How it works
Text-Bro · ⌥A
Select text in any app. Get what you need in one tap.
Translate, proofread, explain, check, or formulate — aiCat understands your needs
based on context.
It reads the situation, not your mind. Editable field → it proof-reads.
Not editable → it explains. Not your language → it translates. Your own language → it checks.
Apply puts it back. One click and the corrected text replaces your
selection, in the app you were already in.
Keep asking. The answer window is a conversation about the same
paragraph — shorter, more formal, in any language, whatever you need next.
One key. Refine, translate, check — whichever the text needs.
aiCat is a desktop app for macOS, Windows and Linux. You select text anywhere on your computer, press one hotkey, and an AI does what you need with it — proof-read, translate, explain, check the facts, read it aloud, or answer a question about it.
How much does aiCat cost?
Free to start, with 10 aiCatCoins a month and everything aiCat does included. Premium starts from $6 a month (40% off the $10 list price) and adds Think More, read-aloud, encrypted memory, 5000-character selections and 3000 coins a month. Team + Offline starts from $18 per member and adds local models, a memory you can edit by hand, and MCP access from your other tools. Coins can also be bought outright instead of subscribing, and they do not expire.
Which operating systems does aiCat support?
macOS (Apple Silicon and Intel), Windows 10/11, and Linux as AppImage, .deb or .rpm.
Does aiCat work in every application?
Yes. It works at the operating-system level rather than through per-app plugins, so it covers native apps, browsers, IDEs, terminals and PDF viewers alike.
Is my text sent anywhere?
Only the text you explicitly act on is sent to the model you selected, for that one request. Your history is stored locally on your device. Team + Offline can run a local model so nothing leaves the machine at all.
