Kayts for Chrome: ask about any page without leaving it

Kayts is coming to Chrome: the chat in the side panel next to any page, and a right-click menu to explain, translate, fact-check or sum up what you read. The extension is in review now.

Kayts is coming to Google Chrome as an extension. It opens Kayts in the browser's side panel, next to the page you are reading, so you can ask about it, sum it up or check what it says without switching tabs. The extension is waiting for review in the Chrome Web Store; as soon as it passes, you will find it on our downloads page. It will be free; like Kayts, it needs an account, which is free too, and it is for adults.

The chat beside any page

Click the Kayts icon in the toolbar (if you don't see it, pin it from the puzzle-piece menu) and the panel opens at the side of the window. It is the same chat as on kayts.ai, built from the same parts: pick a model and how long it thinks, stop an answer, start a new chat. The clock icon opens Recents, your chats grouped by day, with search. When you open the panel again, the chat you had open comes back.

Your chats are kept with your account, so what you start in the panel is on kayts.ai too, and the other way round. In the panel's menu, Open this chat in Kayts takes it to the full site.

Right-click for the Kayts menu

Select some text on any page, right-click it and choose Kayts:

  • Ask Kayts puts the selection into the message box as a card, ready for your question.
  • Explain simply, Translate and Check the facts send it straight away. Translate puts it into the language you use Kayts in; Check the facts answers with sources.

Right-click anywhere on a page, with nothing selected, for two more:

  • Summarize this page sends at once; Ask about this page waits for your question.
  • Both add the whole page to the chat as a source, so a long article is read in full rather than cut to the length of one message. The panel shows the page above the message box.

The menu is in English, Polish or Armenian, following your browser's language. The answers come in the language you chose in Kayts.

Files, photos and your voice

As on kayts.ai, drag a file onto the panel, paste a screenshot with Ctrl+V or use +. Photos go with your message; PDF, Word, Excel and text files are read in your browser. Dictation and voice mode work in the panel too. The first time, Kayts opens a tab where Chrome asks for the microphone, because Chrome doesn't ask inside a side panel; once you allow it there, the buttons work in the panel.

What it reads, and what it doesn't

The extension sees a page only when you choose something from the Kayts menu, and only the tab you clicked in. It doesn't watch your other tabs or run on pages in the background. Chrome's own pages, extension stores and the built-in PDF viewer are closed to every extension, and the panel tells you when you are on one.

Explain simply, Translate and Check the facts each start a chat of their own. Text on a web page can hide instructions meant for an AI, and a new chat has nothing earlier in it that such an instruction could give away.

Sign in through kayts.ai

The extension never asks for your password. "Sign in or sign up" opens kayts.ai in a tab, where you sign in the way you always do: Google, ORCID iD, a password or a code from your email. Kayts then asks whether to allow the extension; after you allow it, the tab closes and the panel is signed in. In the chat, Settings → Account → Connected apps lists it, and Remove access takes that access away.

Your plan, your limits

The panel works with your Kayts plan: the same models, and the same limits, shared with the chat on kayts.ai. A few things stay on the site for now: running Python, charts, creating PDF, Word and Excel files, and reading scanned PDFs. For those, Open this chat in Kayts takes your chat there.

Kayts also has apps for Windows and Linux on the downloads page. If something in the extension doesn't work for you, write to us through support.
