// LOVED BY

Shipped by people who'd rather code.

I burned through Claude.ai and ChatGPT tabs all day. aichat replaced both. The prompt library alone pays for itself in a week.

MO
Mira Ostrowski
Senior Engineer

Switching from Sonnet to GPT-4o inside the same conversation is genuinely a superpower. I draft in one, edit in the other.

DH
Daniel Hayes
Content Lead

Keyboard-first, fast history search, exportable. This is the interface ChatGPT should have shipped two years ago.
