Kairo studio

My creations

Images, videos, documents, slides and websites—all in one place. Images and videos expire after 24 hours; download them to keep a copy.

Create a document manually

Ask in chat: “Make me a PDF about…” or “Create slides from this lesson.” Your files appear here, privately saved to your account.

Your library

Search your work

Type at least two characters. Search checks your saved titles and text.
Your private workspace

Projects

Keep related chats, files, lessons, research and created work together. Kairo uses relevant material when you chat inside a project.

Deleting a project removes its notes and links. Your original chats and files stay in their libraries.

Materials

Files keep their original expiry. To inspect image pixels, attach the image to your message. Project memory does not retrain Kairo.
Kairo Travel

A little less planning. A lot more exploring.

Plan 1–14 days at a time.
Total on-trip budget: stays, food, local transport and activities. Flights excluded.

Your trips stay private and are saved until you delete them.

Where will curiosity take you?

Tell Kairo about your trip. Get days that flow, a practical budget, and room for the things you love.
Kairo Sites

From an idea to a website.

Describe what you want. Kairo will design and build it locally.

Your sites are private until you export and host them.

Websites and browser apps. Payments, accounts and sending forms need a connected backend.

Preview

Your next idea starts here.

A portfolio, a landing page, a shop concept, a game.
Describe it and watch it take shape.
