Sinain HUD overlay

You, Augmented

AI tools today make you work for them. You copy context into chat windows, alt-tab to paste stack traces, explain what you're looking at. You are the middleware.

Sinain inverts this. Your screen, audio, clipboard — one continuous stream feeding your agent. Answers appear in a private HUD overlay, right where you work. When something needs doing, your agent acts — with tools, subagents, and the full power of Claude, Codex, or whatever you're running.

  • Screen → OCR → context digest, continuous. Audio → transcription → awareness, real-time.
  • HUD overlay: insights and actions appear where you work, not in a separate window.
  • No copy-paste. No alt-tab. Your agent already has the context — and the tools to act on it.

Your Agents. Your Stack. Your Rules.

Claude Code for deep reasoning. Codex for async tasks. Goose for local exploration. Junie for JetBrains. Every developer has a different stack — and it changes monthly.

Sinain doesn't pick a side. It's the nervous system that connects them all.

  • Claude, Codex, Goose, Junie, Aider — they all get the same eyes and ears.
  • Hot-swappable knowledge modules, portable across machines and sessions.
  • OpenClaw gateway, sinain-agent standalone, MCP/ACP — your deployment, your choice.

Cloud by Default. Local When It Matters.

Most days, cloud APIs are fast and practical. But when the stakes change — NDA project, client audit, classified codebase — you flip one switch and everything goes local. Same tool. Same workflow. Zero cloud.

  • off → standard → strict → paranoid — four privacy modes, one config line.
  • Paranoid: Ollama + whisper.cpp, zero network calls. Pull the ethernet cable. Still works.
  • HUD invisible to screen capture (NSWindow.sharingType = .none on macOS, WDA_EXCLUDEFROMCAPTURE on Windows).
  • BYOK, BYOM, BYOI — Bring Your Own Keys, Models, Infrastructure.

Quick Start

npx @geravant/sinain start

That's it. On first run, sinain will:

  1. Run an interactive setup wizard — transcription backend, API key, agent, privacy mode
  2. Auto-download the overlay app, sck-capture binary, and Python dependencies
  3. Start all services — sinain-core, sense_client, overlay, and agent

Re-run the wizard anytime: npx @geravant/sinain start --setup

Prerequisites

  • Node.js 18+ — nodejs.org (LTS recommended)
  • Python 3.10+ — brew install python3 (macOS) or python.org
  • OpenRouter API key (optional for local-only mode) — openrouter.ai

Fully local? No API key needed. Ollama + whisper-cli = zero cloud. See Running Fully Local.

macOS Permissions

  1. System Settings → Privacy & Security → Screen Recording — add your Terminal
  2. System Settings → Privacy & Security → Microphone — add your Terminal

Managing sinain

npx @geravant/sinain stop             # stop all services
npx @geravant/sinain status           # check what's running
npx @geravant/sinain start --setup    # re-run setup wizard
npx @geravant/sinain start --no-sense # skip screen capture
npx @geravant/sinain start --no-overlay  # headless mode

Configuration

All config via ~/.sinain/.env (created by the setup wizard).

Variable Default Description
OPENROUTER_API_KEY — Required (unless fully local)
ESCALATION_MODE selective off / selective / focus / rich
OPENCLAW_WS_URL ws://localhost:18789 Gateway WebSocket endpoint
PRIVACY_MODE off off / standard / strict / paranoid

See docs/CONFIGURATION.md for the full reference (30+ variables).

Privacy Modes

Mode What it does
off All data flows freely — maximum insight quality
standard Auto-redacts credentials before cloud APIs (wizard default)
strict Only summaries leave your machine — no raw text sent to cloud
paranoid Fully local: Ollama + whisper.cpp. Zero network calls.

See Privacy Threat Model for the full design.

Hotkeys

Global hotkeys use Cmd+Shift (macOS) or Ctrl+Shift (Windows):

Shortcut Action
Cmd+Shift+Space Toggle overlay visibility
Cmd+Shift+M Cycle display mode
Cmd+Shift+/ Open command input
Cmd+Shift+H Quit overlay

See docs/HOTKEYS.md for all 15 shortcuts.

Running Fully Local

No cloud APIs needed. Local models handle everything:

# 1. Install local transcription
./setup-local-stt.sh

# 2. Install Ollama + vision model
brew install ollama && ollama pull llava

# 3. Start in local mode
./start-local.sh
Model Size Speed Best for
llava 4.7 GB ~2s/frame General use (recommended)
llama3.2-vision 7.9 GB ~4s/frame Best accuracy
moondream 1.7 GB ~1s/frame Fastest, lower quality
