Phaedo

Your cognitive fingerprint, on every AI surface.

Every AI tool today re-learns you from scratch — or never learns you at all. Phaedo learns how you think — communication style, working style, decision pattern — into a portable, encrypted, user-owned cognitive fingerprint, built on your own device from your real usage. It travels with you: any AI tool knows you from the first message, and autonomous agents can consult your decision pattern — “would my human proceed here?” — instead of guessing.

Local. Encrypted. Yours. The fingerprint never leaves your devices unencrypted, and consultations return signals — never your data.
