Connect personal sources and conversations so the twin grows more complete.
Open EchoEcho only knows what you give it. Choose personal sources you are comfortable connecting.
Link the source through the official sign-in. It stays on your personal side, walled from business.
Depth matters more than volume. Honest back-and-forth teaches the twin how you actually think.
The completeness meter is honest: it stays low early and climbs as the twin learns enough to represent you.
