ConOi

AI writer that never repeats a topic or resource, running on a daily schedule from one family to many

ConOi personalizes a daily 'letter' from parent to child, matched to the child's name, age, and interests, and delivers it however the family reads: email today, with a printed A4 letter mailed to the door as the primary long-term channel. Families onboard in a guided wizard, then an AI content engine rotates topics and resources so no letter repeats, writing and sending on a daily schedule without a human in the loop.
