Where most chatbots optimise for a fast reply, this one holds a long document in its head and argues with you about it. Best free option for anything longer than a paragraph.
Limits reset on a rolling five-hour window rather than a message count, so heavy sessions stop you mid-thought. Plan the session before you start.

We recheck every entry. Subscribers hear first when a free tier quietly shrinks.
