Rewrite any text, anywhere on your computer
Select the sentence. Press Option+R. aiCat rewrites it — fixing grammar, and the awkward collocations that quietly mark you as a non-native speaker.
Rewriting normally means: copy the text, open a browser tab, paste it, write a prompt, wait, copy the answer, switch back, paste. Seven steps, every single time, and you lose your train of thought in the middle.
aiCat collapses that to two: select, press. The rewritten version appears over your text with an Apply button that puts it back where it came from.

What makes aiCat's rewrite different
Grammar and spelling
Every mistake is listed separately with a short explanation, so you learn instead of just accepting.
Non-native collocations
"Make a photo" → "take a photo". This is the class of error that generic grammar checkers miss and native readers notice instantly.
Wrong keyboard layout
Typed Russian on a US layout? aiCat recognises the gibberish, converts it, and then rewrites it.
Your tone stays yours
It fixes what is wrong. It does not turn your message into corporate filler.

Why it is cheap
aiCat picks the cheapest model that is good enough for the task in front of it, instead of sending a comma fix to a frontier reasoning model. That single decision is why a month of aiCat costs $6 rather than $20.
You are billed in aiCatCoins: $1 buys 100 coins, one coin is roughly 10 000 tokens of an average text model — about one ordinary request. Coins never expire, so a quiet month costs you nothing.
