Speak.
Structure.
Save.

Record a voice note. Whisper transcribes it. An on-device LLM removes the filler words, infers structure, and saves a clean markdown note. No cloud. No subscriptions. Just your voice.

How it works

01
Record
Tap the mic. Speak naturally — filler words and all. Stop when done.
02
Transcribe
Whisper Small converts your audio to raw text at 16kHz with high accuracy.
03
Structure
Gemma 3 4B removes fillers, detects note type, formats markdown, extracts action items.
04
Save
Stored locally in SQLite. Categorised. Searchable. Never leaves your device.
// features

Built for real use

🔒
Fully private
Audio processed on-device. No analytics, no telemetry, no cloud sync. What you say stays on your phone.
✂️
Filler removal
Strips um, uh, like, you know, basically and 15+ other fillers. Your notes sound like you meant them.
🗂
Auto-categorised
Meeting notes get headers. Todos get checkboxes. Ideas get headlines. The LLM picks the right format every time.
⚡️
Action items
Anything you say you need to do gets extracted into a separate action items list automatically.
🔍
Full-text search
Search across titles, bodies and raw transcripts. Filter by category. Find anything instantly.
📤
Share & export
Copy to clipboard or share the structured markdown note anywhere with one tap.
// categories

Six note types,
zero configuration

The LLM automatically detects what kind of note you're taking and formats it appropriately — you never have to choose a template.
