Three things I built and shipped

BePresent

Your memory for the people you care about.

Write one sentence and an AI agent works out who it’s about, what it is and where it belongs, or asks you before saving anything.

Illustration: the sentence “Dinner with Dad on Friday at 9” becomes a person, an event, a time and a calendar entry, saved with an undo.

Illustration: searching “elecciones” finds an English story about a runoff vote, and a question about the story gets a streamed answer grounded in the article.
