Voice notes for iPhone and Mac - 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.
- macOS (Apple Silicon) - grab the DMG from the latest release, drag FlowFlow to Applications. First launch: right-click > Open (the build is not notarized yet).
- iOS - on the App Store (v1.0, selected regions while EU rollout completes).
- From source - see Setup below; one
makeinstalls on your own iPhone or Mac.
- Voice capture - tap to record, real-time waveform, pause/resume, auto-transcription via Soniox or fully on-device with local Whisper models, background audio with a Dynamic Island live timer
- Offline transcription - download a Whisper model (tiny to large-v3-turbo) in Settings and transcribe in airplane mode; audio never leaves the device, sha256-verified downloads, errors surfaced inline in your language
- 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, agent tools, and a per-conversation theme scope that is remembered when you come back
- Web search in chat - open the composer's + menu and turn web search on for that chat (per conversation, off by default); it queries the web via Exa in parallel with your notes, the two ranked lists fused by Reciprocal Rank Fusion (rank, not score), so fresh web facts and your own notes land in one answer, with web sources in their own section that open in your browser
- Composer tools (+ and @) - a + menu gathers tools and connectors per chat (and on notes): a bottom-sheet you drag down to dismiss on iPhone, a popover with a hover tooltip on Mac; type @ to scope a question to a specific note
- External connectors - link a service like Google Sheets and arm the assistant to one or several of your spreadsheets (pick from the list or paste a link); every tool call passes a governed permission gate, enforced on-device and re-checked server-side, so the model only acts on the sheets you armed and only as the connector's contract allows (account-based, premium). This is the groundwork for an agent marketplace - signed agents, account roles, and server-governed tools - in progress
- Save from chat - keep any answer or a whole thread as a note: AI-titled, embedded for search, filed in the chat's own folder, with its web sources preserved and openable; saved notes render as clean markdown
- Note to chat - jump from any note straight into the chat, already scoped to that note's theme, then one tap on the back arrow returns you to the exact note; the round trip works on iPhone and Mac
- Note threads - group related notes into one titled, chronological thread you read top to bottom and append to in place; a thread needs at least two notes (a lone one stays a plain note), chat can be scoped to a single thread, and threads sync and back up like everything else
- Smart reminders - notes like "pick up the kids at 5pm" become iOS reminders, detected by LLM with one-tap confirm; reminder chips open Calendar on Mac too
- AI organization - auto-title while you write, single-word auto-tags, themes with hierarchy, searchable chats
- Document import - PDF (native OCR for scans), DOCX, TXT, MD, CSV via the native pickers on iOS and macOS, auto-embedded for chat
- Audio playback - play, pause, delete recordings from any note, on both platforms; filler words (euh, um) auto-stripped from transcripts
- A real Mac app - keyboard-first: ⌘N new note, ⇧⌘Enter new chat, ⌘F search, ⌘⌘ switch Notes/Chats, ⌃⌃ theme picker with arrow-key navigation, ⌘←/→ view history, double-Esc home; instant page switches, hover states, native file dialogs (full list in Settings > Keyboard shortcuts)
- Polished by design - one design system: edge-swipe drawers and drag-to-dismiss sheets, a 60fps waveform, anchored context menus, confirm-before-delete everywhere, inline rename with Enter/Esc, copy any note or chat answer in one tap, incremental list rendering that stays smooth past hundreds of notes
- Bilingual - English + French UI, auto-detected, switchable in Settings; even error messages are localized
- 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 (cloud or on-device) → Clean fillers → Auto-embed → Store → AI title
Later: Ask → Embed query → Hybrid search (BM25 + vector) ∥ Web search (Exa, when enabled)
→ RRF fusion → 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
