See it move

One canvas, any depth

A slide in GlideDeck is a frame on an endless canvas, and a frame can sit inside another
frame. Put the summary on the surface and the proof a hundred times deeper. The show flies you
in, and everything stays crisp, because it is all drawn as vectors on your graphics card.

The whole story in one window

Tools on the left, the slide you are working on in the middle, its details on the right, and
your path along the bottom: every stop, with the camera move between each pair. Click a
stop and the editor flies there. Press Ctrl/⌘+K, type a few letters and run any command.
Dark or light, the layout is the same.

Download and install

Your computer	Download	How to install
Windows 10 / 11 (64-bit)	⬇ GlideDeck-x64.msi (always the latest version)	Double-click the file and follow the installer. It adds GlideDeck to the Start menu.
Mac with Apple Silicon or Intel	⬇ GlideDeck.dmg (always the latest version)	Open the file and drag GlideDeck into Applications. The app is signed and notarized by Apple.
Other versions	All releases	Every version, with release notes and SHA-256 checksums.

• Already installed? Choose File → Check for updates….
  GlideDeck downloads the new installer for you, and installing it upgrades your copy in place.
• Code signing policy: Windows installers are signed with a free certificate from
  SignPath Foundation; see the code signing policy.
• Windows says "Windows protected your PC"? Windows warns about new downloads until they
  build up a reputation. Click More info → Run anyway.
• Want to play YouTube, Vimeo or Loom videos inside GlideDeck too? Also install yt-dlp:
  winget install yt-dlp on Windows, or brew install yt-dlp on a Mac. (They always play in
  the web page export.)
• Want to play videos in your slides? Install FFmpeg once: winget install Gyan.FFmpeg on
  Windows, or brew install ffmpeg on a Mac.

What you can do

• Tell a story with space. Zoom out for the big picture, dive into a detail, turn a corner
  to the next idea. Seven camera moves (smooth zoom, swoop, spin, punch and more) make each
  step feel different.
• Import a PowerPoint deck and make it move. Open any .pptx. Your slides, text,
  pictures and speaker notes come along. One click arranges them into a carousel, a spiral,
  orbits or a tree.
• Export back to PowerPoint or PDF. Get a .pptx where every move is a native Morph
  transition, or a PDF to share.
• Share it as a web page. Export a single .html file that plays the show in any browser
  exactly as GlideDeck does: every camera move, animation, parallax layer and effect.
• Bring slides to life. Make text and pictures appear, take the spotlight and leave, with
  a click or automatically. Auto-animate does a whole slide at once.
• Find anything in two keystrokes. Ctrl/⌘+K opens the command search: type a few
  letters to run a command or jump to a slide by its text.
• Start in style. New decks open in Darkroom, the house look: flat graphite, bold type
  and one signal yellow. Daylight is its bright twin. Ten more themes and 18 templates are
  one click away.
• Put YouTube, Vimeo and Loom videos on a slide. Paste a link onto the canvas. The video
  zooms and turns with your slides, and plays in the site's own player in the web page export.
• Present like a pro. Presenter view shows your speaker notes, the next slide and a timer
  on your screen while the audience sees only the show.
• Never lose work. AutoSave keeps your file saved as you go, and if GlideDeck or your
  computer crashes, your unsaved changes are waiting for you next time.
• Use any font on your computer. The font picker shows every installed font in its own
  face, and you can add a font file that then travels with the presentation.
• Let AI do the first draft. Claude and GitHub Copilot can build a complete GlideDeck
  presentation for you, in the same house style, ready to edit.

Carousel: slides glide past over drifting parallax layers	Presenter view: your notes, the next slide, a timer
A PowerPoint deck, imported and arranged as a carousel	Animations, with the click order on the canvas

Get started in two minutes

1. Open GlideDeck and press F5. The welcome canvas is itself a presentation, so you can
   see what's possible. Press → to move on and Esc to stop.
2. Start your own. Use File → New from template (try Carousel), or
   File → Import PowerPoint….
3. Edit. Double-click any text to change it. Add slides with Layouts on the tool rail
   at the left, or press F and drag to draw a new slide (a frame) anywhere on the canvas.
   To find any command, press Ctrl/⌘+K and type a few letters.
4. Write your speaker notes in the Slide tab of the side panel, under Speaker notes.
5. Make it move.
   • Camera move in the Slide tab sets how the camera flies into each slide.
   • Auto-animate in the Animate tab builds a slide's content in.
   • Arrange on the path strip at the bottom reshapes the whole path.
6. Present with F5. With a second screen or projector connected, presenter view starts
   automatically. On one screen, press Alt+F5 to rehearse with your notes.
7. Share. Use Share → Web page (HTML)…, PowerPoint (Morph)… or PDF…, or just send the
   .glide.json file.

To…	Do this
Zoom / move around	Scroll or pinch · drag with Space held down (or the middle mouse button)
Rotate the view	Alt + scroll, or [ ]
Edit text	Double-click it, or select it and press Enter
Resize / rotate an object	Drag a corner handle · drag the round knob (Shift snaps to 15°)
Present	F5 from the start · Shift+F5 from the current slide · Alt+F5 presenter view
See every shortcut	F1

Works with PowerPoint

Bring your decks in. Choose File → Import PowerPoint…, or drop or open a .pptx.

• Each slide becomes a frame on the canvas, in order.
• Text keeps its formatting.
• Shapes, pictures, slide backgrounds and master logos come along.
• Speaker notes appear in presenter view.

Then use Arrange on the path strip to turn the grid of slides into a story. Choose from a
carousel with a parallax backdrop, a spiral, orbits, a tree, a zoom tunnel and more.
(Tables, charts and SmartArt aren't converted yet; GlideDeck lists them for you.)

Paste from PowerPoint. Copy shapes in PowerPoint and paste them into GlideDeck. They
arrive as editable text, shapes and pictures (Windows).

Send decks back out.

• Share → PowerPoint (Morph)… writes one slide per stop on your path, linked with Morph, so
  PowerPoint itself animates the zooms, pans and turns. Icons stay editable vectors; videos are
  embedded.
• Share → PDF… writes one page per slide, exactly as presented.

Share as a web page

Share → Web page (HTML)… (or File → Export web page (HTML)…) writes one .html file that
anyone can open in a browser. Nothing needs to be installed.

• The show is the same show. Camera flights and all seven transition styles, builds
  (typewriter, count up, spotlight and the rest), parallax and fades play exactly as they do
  in GlideDeck. Unlike a PowerPoint export, nothing is approximated.
• Sharp at any zoom. Text is embedded as vector outlines, so it looks the same without the
  fonts, and pictures and SVGs are embedded in the file.
• Videos are copied to a <name>_media folder next to the page; keep the two together.
• YouTube, Vimeo and Loom videos play in the site's own player, right on the slide, and
  move with the camera. YouTube only plays inside pages served from a website (GitHub Pages,
  your intranet…); when the page is opened as a file, a click opens the video on YouTube.
• Controls: → / Space / click for next, ← for back, Home / End, F for fullscreen, the
  mouse wheel to look around, and swipe on a phone or tablet. Press ? for the list.

Feature tour

A canvas without edges

• Put anything anywhere, and zoom a million times deeper. Text, shapes and icons stay
  razor sharp at every size.
• Slides are frames: draw one around anything to make it a stop on your path. Frames are
  invisible in the show unless you give them a border, and moving a frame moves what's inside.
• The path strip along the bottom shows every slide as a thumbnail, with the camera move
  between them. Drag to reorder, and right-click for more.
• Command search: press Ctrl/⌘+K, type a few letters, and pick a command or a slide.

Motion

• Camera moves between slides:

  • Smooth zoom pulls back for context, then dives in.
  • Swoop is a sideways arc with a roll.
  • Spin is a barrel roll.
  • Punch overshoots, then settles.
  • Fade dips through the background.
  • Direct and Cut are plain moves.

• Animations inside a slide (the Animate tab of the side panel):

  • appear effects: fade, rise, focus, zoom, pop, drop, fly in, spin, typewriter, word by word and count up;
  • emphasis: spotlight, highlight marker, underline, color pop, pulse, glow and wiggle;
  • disappear: fade out, sink, zoom out, fly out and shrink.

  Numbers on the canvas show the click order, and Preview plays them in the editor.

• Arrange slides (the Arrange button on the path strip) reshapes the whole path for any number of slides.
  Choose a carousel, spiral, orbits, sunflower, ring, honeycomb, journey, wave, staircase,
  tree, zoom tunnel, snake or grid.

• Parallax: give any object a Depth (Design tab → Layout). In the show, far objects
  drift slower than the slides and near ones faster.

Design that looks good by default

• 18 templates, each a complete story with a theme and a camera path:
  • Business: carousel, pitch deck, roadmap, showcase, branches.
  • Storytelling: journey, summit, spiral, deep dive.
  • Ideas & maps: big picture, hive, orbit, mood board.
  • Teaching: lecture, chapters, workshop, cycle.
• Twelve themes, including the house style, Darkroom (flat graphite, bone-white type,
  one signal yellow) and Daylight (cool white with a cobalt accent), and the 2026 palettes
  Dusk (deep violet with aurora accents) and Cloud (warm white with teal and coral).
  New presentations start in Darkroom. Switching themes restyles text and colours while
  keeping the colours you picked by hand.
• 20 slide layouts, such as title, agenda, three points, comparison, dashboard, team,
  timeline, process, Venn and hub & spokes.
• 1,500 vector icons, soft shadows, gradients, image masks, and smart guides as you drag.
• Design check finds low-contrast or too-small text, empty slides and low-resolution
  images, with one-click fixes.

Content

• Rich text: bold, italic, underline, strikethrough, colours and sizes, bullets and
  numbering. Right-to-left languages (Hebrew, Arabic) work too.
• Fonts: pick any font installed on your computer, previewed in its own face, for one text
  box or for the whole theme (Design tab → Fonts, with nothing selected). Add font file… copies a .ttf or
  .otf into the presentation, so it looks right on any computer.
• Pictures: insert them, drag and drop, or paste screenshots and images from other apps.
• SVG graphics: shown as true vectors.
• Video: with sound, autoplay, loop and mute.
• Web video: paste a YouTube, Vimeo or Loom link (or a link to a video file), or use
  Video → Web video link… on the tool rail. Its poster is saved with the presentation; the video streams when it
  plays. In PowerPoint it becomes the poster, linked to the video.

Your work is safe

• AutoSave (File → AutoSave, on by default) saves a presentation that has a file a moment
  after each change. The top bar shows Saved next to the deck name.
• Crash recovery: unsaved changes, even in a presentation you never saved, are kept in a
  recovery copy. If GlideDeck doesn't close normally, it offers them the next time it starts.

Presenting

• Fullscreen show with keyboard and clicker support. Press B or W to black or white
  out the screen.
• Presenter view: the audience sees the show on the projector, and you see the live slide,
  the next slide, your notes, a timer and the clock.
  • On a single screen, presenter view shows everything in one window, so you can rehearse.
  • Open audience window adds a separate slides-only window when you need one, for example
    to share in a video call.
• Speaker notes live in the Slide tab of the side panel. Use # headings, - bullets and
  **bold**.

Let Claude or GitHub Copilot build your deck

GlideDeck comes with an MCP server and an agent skill. They let Claude (Claude Code,
Claude Desktop) and GitHub Copilot (VS Code and CLI) create presentations for you. The
assistant:

• picks a template, writes every slide and the speaker notes;
• shapes the path and adds animations;
• checks each slide visually;
• saves a normal GlideDeck file you can open and edit.

To set it up, run this once in the folder where you keep your presentations:

glidedeck agent-setup

Then ask, for example:

Create a 7-slide GlideDeck presentation about our Q3 results in q3.glide.json, with
speaker notes, and export a PowerPoint copy.

The server has 27 tools:

• Find: catalog, search_icons.
• Create and read: create_presentation, import_pptx, get_presentation.
• Edit: add_slide, update_elements, add_text, add_image, set_theme, remove_slide,
  add_web_video, arrange_slides, edit_presentation, list_fonts, add_font.
• Bring it to life: animate, auto_animate, set_transitions, set_notes,
  clear_animations.
• Check and deliver: render_slide, export_pptx, export_pdf, export_html, save_as,
  open_in_editor.

It runs on your computer and makes no network calls. Setup for each app and troubleshooting
are in the AI guide.

Support GlideDeck

GlideDeck is free and open source, and it stays that way: no trials, no watermarks, no
locked features. If it saves you time or helps a talk land, you can support its development.

• Sponsor GlideDeck on GitHub. Any amount helps;
  $9 is a great way to say thanks.
• Star the repo and share it. It genuinely helps other people find GlideDeck.
• Report bugs and ideas in Issues.

The Support GlideDeck button in the app (File → About GlideDeck) opens this section.

Privacy

GlideDeck has no accounts, no cloud and no telemetry. Your presentation is one file on your
disk (.glide.json), with its pictures in an assets/ folder next to it. The app goes online
only when you ask it to: when you check for updates (GitHub), and when you add or play a web
video (the video's site). Details are in the privacy policy.

Code signing policy

Free code signing provided by SignPath.io, certificate by
SignPath Foundation.

• Committers and reviewers: nirlotan
• Approvers: nirlotan

Only installers built from this repository by its GitHub Actions release workflow are signed,
and each release is approved by hand. The full code signing policy
and privacy policy are in the repository.

Questions

Can I open my GlideDeck presentation on another computer? Yes. Copy the .glide.json file
together with its assets/ folder.

Do my viewers need GlideDeck? No. Present from your computer, send a web page
(Share → Web page (HTML)…) that plays the full show in any browser, or export to PowerPoint or PDF.

Will my fonts look right on another computer? In a web page export, yes: text is embedded
as outlines. To edit on another computer, add the font with Add font file… in the font
picker, and it travels in the presentation's assets/ folder.

Where did my notes go after importing a PowerPoint? They come along. You'll find them in the
Slide tab of the side panel, under Speaker notes, and in presenter view.

For developers

Build from source

You need Rust 1.88+ (rustup.rs) plus a platform linker: the Visual Studio
C++ Build Tools on Windows, or xcode-select --install on macOS.

git clone https://github.com/nirlotan/GlideDeck.git

cd GlideDeck

cargo run --release -p glidedeck

See RUNNING.md for the full guide: platform notes, every shortcut, and the
complete CLI and JSON reference. Tests (core maths, exporter, renderer and end-to-end UI flows
driven through egui_kittest on a real GPU device):

cargo test --workspace

Command line and JSON operations

The same program is also a headless tool:

glidedeck new talk.glide.json --template carousel

glidedeck apply talk.glide.json examples/add-slide.ops.json

glidedeck render talk.glide.json --step 3 --out slide3.png

glidedeck import-pptx deck.pptx --out deck.glide.json

glidedeck arrange deck.glide.json --layout carousel

glidedeck export-pptx talk.glide.json --out talk.pptx

glidedeck export-html talk.glide.json --out talk.html

Operations are plain tagged JSON, applied atomically per batch:

[
  {"op": "add_element", "element": {"id": "hello", "transform": {"x": 0, "y": 0},
    "kind": {"type": "text", "content": "Hello", "role": "title"}}},
  {"op": "add_element", "element": {"id": "f1",
    "kind": {"type": "frame", "width": 1600, "height": 900}}},
  {"op": "add_step", "frame": "f1", "transition": {"style": "smooth", "duration": 1.4}}
]

The document format ("format": "glidedeck/1") is stable, pretty-printed JSON. Media lives in
assets/, named by content hash. Full reference: RUNNING.md § 4.

Windows MSI installer

Requirements: the Rust toolchain and the WiX Toolset 3 binaries. Download
wix314-binaries.zip from the WiX releases and
unzip it anywhere; no installation is needed.

powershell -ExecutionPolicy Bypass -File packaging\windows\build-msi.ps1 -WixDir C:\tools\wix314

The script builds the release binary, which embeds the icon and version info, and writes
dist\GlideDeck-<version>-x64.msi. The installer:

• installs per machine into Program Files\GlideDeck;
• creates Start-menu and (optional) desktop shortcuts;
• adds the glidedeck CLI to PATH;
• ships the example deck;
• upgrades earlier versions in place (stable UpgradeCode, major-upgrade rules).

To trust it with SmartScreen, sign it with a code-signing certificate:

signtool sign /fd SHA256 /tr http://timestamp.digicert.com /td SHA256 /a dist\GlideDeck-0.1.6-x64.msi

The update check in the app looks for a .msi (Windows) or .dmg (macOS) asset on the latest
GitHub release, so attach installers to each release.

macOS DMG

Run these on a Mac with Rust and the Xcode Command Line Tools. Build for this Mac's
architecture, or as a universal binary:

packaging/macos/build-dmg.sh

UNIVERSAL=1 packaging/macos/build-dmg.sh

The script builds the release binary (with UNIVERSAL=1, both architectures joined with
lipo). It then assembles dist/GlideDeck.app from packaging/macos/Info.plist, generates the
.icns icon, signs the app and writes dist/GlideDeck-<version>.dmg.

To distribute, sign and notarize with an Apple Developer ID. First store notarization
credentials once:

xcrun notarytool store-credentials glidedeck-notary --apple-id [email protected] --team-id TEAMID

Then build, sign, notarize and staple in one go:

SIGN_IDENTITY="Developer ID Application: Your Name (TEAMID)" NOTARY_PROFILE=glidedeck-notary UNIVERSAL=1 packaging/macos/build-dmg.sh

Find your identity with security find-identity -v -p codesigning. Without signing, ad-hoc
signed apps run on the Mac that built them. On other Macs, right-click the app and choose
Open the first time.

For CI, notarize with an App Store Connect API key instead of a stored profile:
NOTARY_KEY_PATH=AuthKey_XXXX.p8 NOTARY_KEY_ID=XXXX NOTARY_ISSUER=<issuer id>.

Releases with GitHub Actions

.github/workflows/release.yml builds the signed and notarized universal DMG on macOS and the
MSI on Windows. To publish a release:

1. Bump version in Cargo.toml and add packaging/release-notes-v<version>.md (used as the
   release text).
2. Commit, then tag and push: git tag v0.1.7 && git push && git push origin v0.1.7.

The release gets GlideDeck-<version>.dmg, GlideDeck-<version>-x64.msi, SHA-256 files, and
stable-name copies GlideDeck.dmg / GlideDeck-x64.msi for the download links above. To test
signing without publishing, run the workflow by hand (Actions → Release → Run workflow)
and download the installers from the run's Artifacts.

Signing needs these repository secrets: APPLE_CERTIFICATE (Developer ID Application .p12,
base64), APPLE_CERTIFICATE_PASSWORD, APPLE_SIGNING_IDENTITY, and for notarization
APPLE_API_ISSUER, APPLE_API_KEY (key ID) and APPLE_API_KEY_P8 (the .p8 contents).

Architecture

crates/
  glide-core     Document schema (serde JSON), f64 camera maths, transitions, builds,
                 themes, the atomic Op set. No GUI/GPU dependencies.
  glide-render   wgpu renderer: lyon tessellation, cosmic-text shaping and editing,
                 vector icons, SVG (usvg), mipmapped images, video (FFmpeg + cpal),
                 analytic shadows, offscreen MSAA targets, headless readback.
  glide-pptx     OpenXML writer: path → slides linked with Morph; vector icons,
                 native SVG, embedded video.
  glidedeck      The app: eframe/egui editor (top bar, tool rail, side panel, path strip, command search,
                 galleries, design check), the show and presenter view, animations,
                 PowerPoint import, PDF export, the CLI and the MCP server.

Design decisions:

• Tessellate once, transform forever. Meshes live in element-local space on the GPU;
  moving and camera motion only update a per-instance affine.
• Precision at depth. Transforms are f64, and each element's matrix is composed relative
  to the camera before dropping to f32.
• One renderer, many outputs. The editor, thumbnails, galleries, the show, PDF and PNG
  export all come from the same offscreen renderer.
• The show renders a scene. Animations and parallax produce a per-frame copy of the
  document; the file itself never changes while presenting.
• Non-destructive and diff-friendly. Geometry and transforms are stored separately, files
  are pretty-printed JSON written atomically, and media is content-addressed.

Roadmap

• Tables and charts from PowerPoint
• Audio clips, video trimming, and video export of the path
• Grouping, more shape types and connectors
