// why it's different

Built for shipping, not just chatting.

Six things every other AI coding tool gets wrong — and we got right.

01

AI that reads your files

Claude 4.5 and GPT-5.2 get full context of every file before suggesting changes. No more copy-paste-into-chat.

02

Run, don't just write

Sandboxed Python execution and an HTML/JS preview iframe — see your code work without leaving the page.

03

Multi-file projects

Real file tabs, real Monaco editor, real save-and-load. Not a single-file gimmick.

04

Apply patches in one click

When the AI ships a code block with a filename, hit Apply and it lands in the right file.

05

Bring your own login

Email, Google, or GitHub — JWT under the hood, projects saved to your account.

06

Auto-loaded sample project

New accounts spawn with a fully working snake game and pre-seeded AI chat — the wow moment is instant.
