It's a fork of VS Code with some AI features sprinkled in. It writes around 80% of my code, these days.
It also has a few useful features:
- a chat interface where you can @-mention files, folders, and even documentation
- if you edit a line of code, it suggests edits around that line that are useful (e.g. you change a variable name and it will suggest updating the other uses, which you accept just by pressing Tab)
- as you're writing/editing code, it will suggest where your cursor might go next — press Tab and your cursor jumps there
