Start with one thought

A note, decision, task or conversation summary is enough. Your first entry will appear here.

One record, many contexts

Use the Related entries field to link information across Life and Projects. Selective sharing only includes the entry you explicitly choose.

AI continuity: not connected yet

You can record conversation summaries now. Automatic ChatGPT/Claude ingestion and the historical Codex migration require separate authorised integration.

Backups & settings

Your records live only in this browser's storage. This is not yet the historical local Life Codex or a synced account. Safari may clear local data; an encrypted backup is essential.

Create encrypted backup

Download one AES-256-GCM encrypted file. Keep its password somewhere safe: it cannot be recovered for you.

Restore encrypted backup

Restoring replaces all entries on this device. First back up anything you want to keep.

Encryption protects downloaded backup contents, not records while this app is unlocked on your device. No automated AI ingestion, cross-device sync, remote hosting of your records, or background backup. Never put passwords in chats or GitHub.
