The (short) story

Wispr Flow raised $81 million to build a voice dictation app.
I got annoyed, spent 3 months of late nights building my own version, and open-sourced it.

That's it.
No funding. No team. Just one stubborn developer who hates subscriptions.

This is what open source is supposed to be.

Why people actually use it

• Hold Fn → speak → release → clean, punctuated text appears anywhere
• Removes "um", "like", all fillers automatically
• Fixes grammar, can rephrase, bullet-point, or even generate text
• Tiny actions already work ("open YouTube", "set 5-min timer")
• Full Prompt Engineering: Every behavior is customizable. Tweak how Jarvis formats mail, cleans dictation, or behaves as an assistant.
• Fully offline with local Whisper or NVIDIA Parakeet (via Sherpa-ONNX)
• 100% Private, Blazingly Fast support for local LLMs via Ollama
• Or use cloud speed with Deepgram + Gemini (1M tokens/day free) — Deepgram requests default to mip_opt_out=true

Zero tracking. Zero telemetry. Zero bullshit.

Quick setup (30 seconds)

1. Download & open the app
2. Go Local (Recommended for privacy):
   • Settings → Transcription → Enable Local Model
   • Choose Whisper (tiny/base/small) or Parakeet (NVIDIA's 600M param model)
   • Settings → AI Models → Enable Ollama (requires Ollama installed)
3. Or Go Cloud (Recommended for speed/accuracy):
   • Paste free Deepgram + Gemini keys
4. Hold Fn and talk

That's literally it.

🦙 Ollama (Local LLM) Support

Jarvis now supports running any LLM locally via Ollama. It's fast, private, and free.

1. Install Ollama: Download here
2. Pull a model:

   # LFM2 (optimized for speed)
   ollama pull sam860/LFM2:1.2b
   
   # Llama 3 (standard)
   ollama pull llama3
   

3. Enable in Jarvis:
   • Settings → AI Models → Enable Use Ollama
   • Select your model from the dropdown (Jarvis auto-detects them!)

⚡ Performance Note

Running models locally depends heavily on your hardware.

• Enabled AI Post-Processing: Adds ~1-3s latency on typical M1/M2 chips.
• Disabled AI Post-Processing: Instant transcription.
• High-End Hardware: M1/M2/M3 Max/Ultra chips are nearly instant.

For Lightning Fast Performance:
If speed is critical, use Deepgram + Gemini (Cloud) or Local Whisper + Gemini Flash, which are significantly faster than local LLMs on standard hardware.

Open source isn't about beating giants.
It's about making sure no one ever has to pay them.
