A short, practical walkthrough — no account needed to try it.
Step by step
- Install aiCatDownload the build for your operating system and open it. Two minutes, no account needed to start.

- Select any textIn any app: your mail client, an IDE, a browser, a PDF viewer.
- Press Option+R (Alt+R on Windows and Linux)The rewritten version appears in a small window over your selection, with the corrections listed.

The default hotkeys (all editable)
| Keys | What happens |
|---|---|
| Option / Alt | aiCat guesses: rewrite if you are writing, translate if you are reading something foreign, proof-check otherwise |
| Option + R | Refine / rewrite |
| Option + T | Translate |
| Option + P | Proof check |
| Option + D | Detect AI |
| Option + E | Explain |
| Option + C | Start a chat with the selection attached |
| Option + S | Chat with web search |
| Option + L | Read aloud — or record you, if nothing is selected |
| Option + W | Dictate: speak, and the text appears at your cursor |
| Option + I / V | Generate an image / a video |
| Option + H | History of everything you selected and what came back |
Why this is faster than the alternative
The usual route is: copy, switch app, paste, prompt, wait, copy, switch back, paste. Eight actions and a broken train of thought.
Selecting and pressing one key is two actions, and you never leave what you were doing. Over a working day that difference compounds into real time.
