Character.AI

Been using it daily for a month. It genuinely changed how I work: I describe the feature, review the diff, ship. The occasional wrong turn is easy to catch because it explains its plan first.

Excellent core experience. Docking a star because pricing gets steep once you're a heavy user, and the free tier limits hit faster than expected.

it's fine? my little sister loves it. i used it to rehearse a job interview and it was surprisingly useful. the filters are heavy handed and the app is full of ads now.
