One question: a three-day trip to Lisbon on a budget. Watch Kayts plan it; the button turns the sound on.
Writing
Write with an editor beside you
Emails, essays, posts and messages. Paste what you have or start from one sentence; Kayts writes in your language and keeps your voice.
- Rewrites in the tone you ask for: shorter, warmer, more formal
- Answers in the language you write in, and translates between languages
- Dictation: say the draft, read the result
- Code too: Python and JavaScript run right in your browser
Make this friendlier, but keep the deadline: “The heating has been off for three days. Fix it this week or I’ll call the housing office.”
Hi Mr. Kowalski, the heating in the flat has been off since Tuesday, and with the cold nights it's getting hard to stay in.
Could you have someone look at it this week? If that's not possible, I'll need to ask the housing office for help. Thank you!
Files
Ask your files anything
Drop a PDF, a Word or Excel file, a photo or a screenshot into the chat. Kayts reads it on your device and answers from what's inside.

- Photos and screenshots: a menu, a form, a whiteboard, a chart
- Scanned PDFs with text recognition, up to 30 pages

- Your files
- Searches the OpenAlex catalog with filters for year, type, topic and open access, sorted by relevance, citations or date
- Adds a paper in one click and fetches its full text when it's open access; otherwise it works from the abstract
- Reads PDF, Word, Excel, CSV and text files right in your browser
- Cites its sources like [1] and says when they don't cover your question
- In any chat, looks up papers on its own when you ask about research, and lists the ones it found
Up to 12 sources in one chat. Scanned PDFs are read with text recognition (OCR), up to 30 pages; the result may contain errors.
Why do residual connections help very deep networks?
Plain networks get harder to train as they grow deeper: past a point, even training accuracy drops.
Residual blocks learn only a change to their input, which is added back through a shortcut. That made networks with over 100 layers train well. 1

Models
Five models, one assistant
All five are in the chat's menu; your plan decides which you can use. Fast for everyday questions, stronger for demanding work.
Your data
Your conversations stay yours
We collect only what Kayts needs to work, and we never sell your data.
Stored in the EU
Your account and chats are kept in the European Union.
You decide about training
Your chats can help train future Kayts models. One switch turns it off, when you sign up or anytime in settings. For users under 18 it stays off unless they turn it on.
Files read on your device
Research files are opened in your browser. Only their text goes with your questions, never the file itself.

Five: Mihr, our fast model for everyday tasks; Anahit, our smarter model for complex work; Siran and Nareia, stronger models for demanding work and long projects; and Monte, our most powerful model. Mihr and Anahit are named after Armenian deities: Mihr, god of the sun and light, and Anahit, goddess of wisdom. Every model can think a question through before it answers; Mihr, Anahit, Siran and Monte also read images. Free includes Mihr and a taste of Anahit; Plus adds Anahit, Pro adds Siran and Nareia, and Max adds Monte.
