Instant AI · fast and simple
Select text anywhere.
AI does what you want
in one tap.
aiCat lives on a hotkey, not in a browser tab. Highlight anything — in Slack, in your IDE, in a PDF, in a form — and rewrite, translate, proof-check, detect AI, explain, listen or dictate. aiCat guesses what you need and does it instantly.

Three seconds, start to finish
The whole point is that there is no workflow to learn.
Select the text
Anywhere on your computer. No extension, no plugin, no pasting into a website.
Press one key
Option alone lets aiCat decide. Option+T translates, Option+R rewrites, and so on. Or click the ✨ button that appears next to your selection.
Apply
The result appears over your selection with the details — corrections, keywords, sources. One click puts it back in place.
aiCat guesses what you need
Press Option with nothing else and aiCat reads the situation: it knows whether you are writing or reading, and whether the text is in your language.
→ Refine
Grammar, spelling and the non-native collocations that give you away — with every correction explained. Wrong keyboard layout is detected and fixed first.
→ Translate
Translation into your language, plus up to ten keywords with transcriptions so you gradually stop needing it.
→ Proof check
Is this correct? What is unsupported? What is missing? Each claim with a status and, where it exists, a source.
Ten things, one hotkey each
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.
Learn more → ⌥RA paraphraser that lives in your keyboard, not in a browser tab
Select any sentence in any application and get a clean paraphrase in one tap — no pasting, no tab-switching, no word limit games.
Learn more → ⌥PProofreading that checks the facts, not just the commas
Option+P on any selection: is this correct, what is unsupported, and what should you also know. With sources.
Learn more → ⌥TTranslate whatever is on your screen, without leaving it
Select foreign text anywhere and press Option+T. Translation, plus the ten keywords worth learning with transcriptions.
Learn more → ⌥DAI checker that works on whatever you are reading
Option+D gives you a likelihood that the selected text was written by a model, with the specific signals that produced the number.
Learn more → ⌥ESelect the confusing part. Press one key.
Option+E turns jargon, legalese, an error message or a dense paragraph into a plain sentence — then a chat if you want to dig in.
Learn more → ⌥LHave anything on your screen read to you
Option+L reads the selection out loud, with speed, volume, trimming and save. Nothing selected? The same key starts recording you.
Learn more → ⌥WDictate into any text field on your computer
Press Option+W, talk, stop. The transcript appears at your cursor — in Slack, in your IDE, in a form, anywhere.
Learn more → ⌥CSelect-to-Ask — the chat already knows what you are looking at
Option+C opens a chat with your selection attached and the first answer already being written. Option+S does the same with web search on.
Learn more → ⌥ISelect a description. Get the picture.
Option+I sends whatever you highlighted to an image model and opens the result in a chat you can keep refining.

Questions
What is aiCat?
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 — rewrite, translate, proof-check, detect AI, explain, read aloud, dictate, or start a chat.
How much does aiCat cost?
Free to start, with 10 aiCatCoins a month and every text task included. Premium is $6 a month (40% off the $10 list price) and adds voice, image and video generation, 5000-character selections and 3000 coins a month. Team + Offline is $18 per member and adds local models that work without internet.
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.
