Everything it does, on your phone

This list follows the app as it is today. Every item works in the Android test build. What it does not do is at the bottom.

Recording

Records with the screen off: Runs as a foreground service with a quiet notification.
Pause and resume: Also automatic when a call comes in.
Live text: Text appears while people speak (NVIDIA Nemotron). With the compact models (phones with less than 6 GB of RAM), Whisper writes each stretch of speech after a short pause.
Meeting language: Eight languages or automatic detection; your last choice is remembered.
Silence: After five minutes of silence the app asks whether to stop. It never stops by itself.
Airplane-mode label: Shown on every recording made fully offline.

Final transcript: Transcribed again afterwards with NVIDIA Parakeet, with a time for every word. If that fails you keep the live text and can retry.
Speaker separation: After the meeting, on the device. Every speaker gets a colour.
Name speakers: During and after recording.
Remember voices: Off by default. Voice profiles live only in the encrypted database; delete one or all.

Six-part summary: Summary, key points, decisions, action items, next steps and open questions. In the app's language.
Action items: Who and when, and one tap to your phone's calendar.
Open points from last time: In the next meeting with the same people.
Ask questions: Chat about one meeting; answers link to the transcript.
Insights: Talk time, who spoke when, chapters, mind map and a careful estimate of the tone (only when it is reliable enough).

Library: Search everything, your own labels, filters for date, length and language.
Share as text: Summary, parts, action items or (part of) the transcript through the share sheet.
Privacy receipt: Per meeting: whether there was a connection during recording, how everything is encrypted, what happened to the audio and which models ran.
Auto-delete audio: Choose off, 1, 7 or 30 days. By default audio is already deleted once the transcript is done.

Android 11 or newer: Vault Notes is Android only.
Large screens: On tablets and foldables the list and the meeting sit side by side, never across the fold.
App in eight languages: Dutch, English, German, French, Spanish, Portuguese, Italian and Polish.

Real screens from the app, filled with a sample meeting.
