Tephra — Speak it. Find it. Ask it.

Just talk

Tap record and think out loud — keep going with the screen locked or mid-walk. Live controls sit in the Dynamic Island.

AI does the filing

Your voice is transcribed on your device; then the text is formatted by AI — titled, summarized, tagged and linked to the people and ideas you mentioned. Never a raw transcript.

Your vault, your files

Plain Markdown with YAML and [[WikiLinks]] in your own iCloud Drive. Works with Obsidian. Yours forever.

Ask Tephra

Speak it in.
Ask it back.

Ask a question out loud — “what did I decide with Marco?” — and Tephra answers from your own notes, with the sources it used. The search runs on your device; only the answer step touches the AI.

✓ Ask by voice or by typing

✓ Every answer cites the notes it came from

✓ On-device search — your notes stay yours

Ask Tephra

“What did I decide with Marco about the notification service?”

You agreed to start with a simpler CRUD approach with Marco Bianchi, deferring event sourcing for compliance until later.
