# Guides to every feature

A page per feature, with pictures of the screens and numbered arrows. The same guides are in the app, under Guide. What a feature is and whether it has been seen working is on [Ideas and where they stand](../ideas/index.md); what exists is the [reality file](../built/index.md).

| Guide | App | What it covers |
|---|---|---|
| [Record a voice note](record/index.md) | VoiceDebrief | Choose who the note is for, then one button records. |
| [Open a note: listen, send, save](note/index.md) | VoiceDebrief | A note opens with its one sentence as the heading, then what has happened to it, the recording, the transcript and the debrief. |
| [The library: every note, and what each one is doing](library/index.md) | VoiceDebrief | Every note kept on this device, newest first, by day. |
| [Vaults: your notes, encrypted, on the device first](vaults/index.md) | VoiceDebrief | A vault is an encrypted, version-controlled folder you own. |
| [Contacts: send a note to somebody](recipients/index.md) | VoiceDebrief | A contact is a person, another device or an agent session that has given you their link. |
| [What happened since you last looked](briefing/index.md) | VoiceDebrief | When you open the app, a card on the Record tab says what is new: an update, with a link to what changed, and what happened to your notes since you last opened it. |
| [Settings: language, saving, experiments](settings/index.md) | VoiceDebrief | Settings is under More, with the few things to set once, and the places for the rest: who you send to, the experiments and what the app has done. |
| [SGit Vaults: open a vault you were sent, or make one](sgit-start/index.md) | SGit Vaults | SGit Vaults keeps photos, videos, large files and secrets in encrypted vaults that a teammate can open. |
| [SGit Vaults: inside a vault, and its history](sgit-vault/index.md) | SGit Vaults | A vault holds folders and files, like a folder on a computer, with every change kept as a signed commit. |
| [SGit Vaults: share a vault, and create one on the server](sgit-share/index.md) | SGit Vaults | Sharing gives somebody the vault's key. |
| [SGit Vaults: secrets, kept in a vault](sgit-secrets/index.md) | SGit Vaults | A secret is a password, a Wi-Fi network, a server or a card, kept as one encrypted file in a vault, behind Face ID. |
