Guides & comparisons
Everything aiCat does, how it stacks up against the tools you already pay for, and how to spend far less on AI without noticing the difference.
What aiCat does
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.
A 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.
Proofreading 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.
Translate 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.
AI 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.
Select 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.
Have 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.
Dictate 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.
Select-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.
Select 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.
