Trace

A private memory for your life, on iPhone and Mac. Capture your day, keep only the memories you approve — each with a receipt — and ask an on-device assistant that shows you why it knows what it knows. Nothing leaves your devices.

Capture

Record voice, scan documents, or jot a thought. Transcription runs on your device — no upload, no account required.

Approve

Trace proposes memories worth keeping. You decide what stays and what's forgotten. The assistant only knows what you allow.

Recall

Ask in plain language. Every answer cites its source — a receipt back to the exact moment it came from.

iPhone + Mac

Trace on iPhone captures and remembers. Trace Desk on your Mac becomes a private command center to review, approve, and chat with everything you've kept — over your own local network.

Private by architecture

Not by policy. On-device transcription and recall, consent for every memory, and a source receipt for every answer. Your memory, your devices, yours.
