inFin is an AI voice notes app for iPhone, iPad and Mac that records, transcribes and translates audio on-device, then turns recordings into summaries, action items and web clips.
About inFin
What Is inFin
inFin is a note-taking app built around voice. You tap once to record a lecture, a meeting or a passing idea, and the app writes it out as text while you speak. The same entry point also handles typed notes and clipped web pages, so voice memos, text and saved articles end up in one library.
What separates inFin from cloud-first note apps is where the work happens. Speech recognition and Chinese to English translation run on the device, not on a remote server. That keeps working on a plane or in a basement with no signal, and it means your recordings stay in local storage instead of a company database.
The trade-off is scope. On-device transcription is tuned for Chinese and English, so other languages lean on online models or fall back to plain text. The AI summaries, mind maps and rewriting tools that many people want most sit behind the inFin+ subscription rather than the free tier. The app is also Apple-only, with no Android or Windows build.
Getting Started
- Download inFin from the App Store on an iPhone, iPad or Mac and open the app.
- Allow microphone access, then tap record and start talking. The transcript appears as you go.
- Pick a language pair if you want live translation, or leave it on plain transcription.
- Save the note, add tags if you want, and run an AI summary when you need the short version.

Key features
On-device transcription that works offline
inFin runs its speech recognition on the device rather than on a server. The company says speed can be up to twice that of cloud-only tools, and recordings keep transcribing with no connection at all. Anything you capture offline syncs once you are back online, so a lost signal doesn't cost you the note.
Real-time Chinese and English translation
The app translates between Chinese and English as you speak, showing both sides of a conversation live. This fits bilingual meetings or language classes where you need to follow along in the moment. The pairing is fixed to these two languages, so it won't cover other combinations on its own.
AI summaries, action items and mind maps
On the paid plan, inFin+ turns a recording into a structured summary, a to-do list and meeting minutes. The company claims it can process two hours of audio in around ten seconds. The same tools draft, polish, expand and proofread text, which covers light writing work on top of note-taking.
One-tap web clipping
A built-in clipper saves web pages and image posts, filters out ads, and pulls the core content into your library. Everything lands under tags you set, and clipping works offline too. For people who collect references as they read, it keeps those saves in the same place as their voice notes.
Tag-based organization and search
Voice notes, typed notes and clips all share one tag system, so you can group a project or topic regardless of how it was captured. Notes stay editable offline and searchable later. The point is to avoid the usual mess of scattered apps and documents.
Local encrypted storage and export
All notes are encrypted and kept on the device, which the developer frames as a private knowledge base rather than a cloud service. You can export a note to Word or as an image at any time. The company states it does not read or sell user notes.
