Cove Voice
Record meetings, lectures, and ideas — transcribed and organized on your phone, never on a server.
Features
-
Long-form recording
Record up to six hours in a single session. Cove auto-segments by silence and pause, so a long call stays browsable.
-
On-device transcription
Whisper-grade transcription runs entirely on your phone. No upload, no per-minute fee, no waiting for a queue.
-
AI-organized notes
Cove turns a raw transcript into action items, key quotes, and an outline you can paste straight into your tool of choice.
-
Stays on your phone
Recordings, transcripts, and AI notes live only in your phone's storage. There is no Cove server to sync to.
How people use it
-
Capturing a client discovery call
Record a 60-minute call, then ask Cove for action items, decisions, and follow-up questions. The whole transcript stays on your phone — no NDA-violating cloud upload.
-
Turning a lecture into a study guide
Record a Tuesday-morning lecture. By the time you walk to lunch, Cove has the outline, key terms, and three review questions ready — even on dorm Wi-Fi.
-
Brain-dumping ideas on the drive home
Talk for twenty minutes while you drive. Park the car, open Cove, and you have a tidy todo list and a saved transcript instead of a 20-minute audio file you will never replay.

Who is this for
- Knowledge workers running back-to-back calls who don't want every conversation siphoned to a SaaS dashboard.
- Students who want their lecture audio without paying a monthly transcription bill.
- Anyone who would rather their recordings never touch a server they cannot audit.
When not to reach for it
- Live captioning during the meeting itself — Cove transcribes after the recording ends, not in real time.
- Multi-speaker enterprise transcription with speaker-separation SLAs — for that, hire a service with human review.
Frequently asked questions
How does Cove transcribe without the internet?
Cove ships an on-device transcription model alongside Gemma. The first launch downloads the models once; after that every recording, transcript, and AI note is computed locally on your phone.
How long can a single recording be?
Up to six hours per session in the current build. Longer recordings can be split across sessions; Cove preserves segments and lets you stitch transcripts together.
How accurate is the transcription?
On clean single-speaker audio in supported languages, Cove sits within a few percent of cloud transcription quality. In noisy multi-speaker rooms accuracy drops — that is a real limit of running locally on a phone, not a marketing footnote.
Can I export to Notion, Obsidian, or Markdown?
Yes. Every transcript and AI-organized note can be exported as Markdown, plain text, or copied straight to clipboard. Cove never silently uploads anything during export.
