Voice notes app for mobile - 100% Rust, built with Dioxus.
Featured on Awesome Dioxus.
Most of my ideas come when I'm walking or between two tasks. And they vanish just as fast.
FlowFlow is a voice notes app that captures what you say, transcribes it, and lets you chat with your notes later. You ask "what was that pricing idea?" and the right passages come up - with links to the original notes.
No manual searching. No folders to dig through. Just talk, and find it later.
- Voice capture - tap to record, real-time waveform, pause/resume, auto-transcription via Soniox, background audio with a Dynamic Island live timer
- Multi-device sync - encrypted LAN P2P between iPhone and Mac (Noise protocol, no server, no cloud), QR pairing, real-time UI refresh, zero data loss by design
- Backup & restore - export everything (notes, audio, vectors) as one archive via the share sheet, API keys and pairing secrets never leave the device; import is a validated, crash-safe atomic replace, and sync reconverges without resurrecting deleted notes
- RAG chat - powered by rig: ask questions about your notes, get answers with tappable sources; hybrid search (BM25 + vector + RRF + LLM rerank), temporal queries, folder-scoped chat, agent tools
- Smart reminders - notes like "pick up the kids at 5pm" become iOS reminders, detected by LLM with one-tap confirm
- AI organization - auto-title while you write, single-word auto-tags, folders with hierarchy
- Document import - PDF (native OCR for scans), DOCX, TXT, MD, CSV via the native iOS picker, auto-embedded for chat
- Audio playback - play, pause, delete recordings from any note; filler words (euh, um) auto-stripped from transcripts
- Bilingual - English + French UI, auto-detected, switchable in Settings
- Local-first - SQLite for metadata, LanceDB for vectors, your data stays on your devices
100% Rust. Zero JavaScript. The UI is Dioxus rendering natively on iOS and macOS; the Dynamic Island Live Activity is the only Swift, bridged via FFI.

Talk → Record → Transcribe → Clean fillers → Auto-embed → Store → AI title (1-3 words)
Later: Ask → Embed query → Hybrid search (BM25 + vector + RRF)
→ LLM rerank → Temporal boost → Tag-enriched context → Agent with tools → Answer with sources
Sync: Save → debounced trigger → Noise-encrypted LAN session → version-vector merge → UI refresh < 1 s
Backup: Export → scrubbed SQLite snapshot + WAV + manifest (zip) → share
Import → read-only validation → atomic swap at next launch → vector index rebuilt offline
