Chat, work
& code, in private.
Anonymous by default · messages not stored on our servers · open-weight models · what is and is not protected
A complete assistant, for your everyday.
Understand, draft, compare, decide. The best open models, served by European GPUs.
An agent that delivers the file, not just the answer.
Up to 8 chained steps: research, calculation, file generation. Kowork runs Python, produces your Excel, Word, PDF and slide decks, and connects to your tools (Linear, GitHub, Notion, Slack).
An agent that writes, runs, and verifies.
Kode reads your project, proposes a fix, runs the tests, and proves it works.
What happens to a question,
in four steps.
No account needed
Your question travels over TLS with no account or identifier attached. The computer that answers reads it, as any online service would.
A peer GPU answers
A computer lent by its owner hosts the model, never a Korai datacenter.
Anonymous tokens pay
One anonymous token covers the request. Neither your card nor your email travels with it.
Tokens are not linked to you
Korai cannot match a spent token to the one it signed. Your IP address and a random browser id can still link chats from one browser to each other.
For work, for life,
and everything else that stays private.
Writing
From rough notes to finished text: letters, contracts, articles, messages. Without your drafts training someone else's model.
Fiduciary & legal
Case analysis on open-weight models. Check your professional-secrecy obligations first: the computer that runs the model reads what you send.
Code
Write, debug, understand a codebase. The Kode agent runs the tests and proves it works.
Documents
Summarize, extract, cross-reference your PDFs and spreadsheets. Files are read in your browser and travel with your message, never stored on Korai's servers.
Health
Ask the questions you don't want in any advertising history. Korai builds no ad profile and does not store your messages.
Research
Ein Thema gründlich erkunden mit dem Deep-Modus: Das stärkste Reasoning-Modell arbeitet es Schritt für Schritt durch.
What Korai guarantees,
and what it doesn't.
Three things we can state plainly today. The limits are listed on the About page.
Encrypted in transit
TLS on every hop, from your browser to the host computer. Not end to end: the servers on the way read the message while it passes.
Tokens, not accounts
In anonymous mode you pay with blind tokens and no account is sent with your message. Chats from one browser still share a random id.
No stored messages
Korai's servers do not store the text of your messages. Your history stays in your browser unless you turn on encrypted sync.
Always the best
open-weight models on the market.
Three profiles cover speed and everyday reasoning (Qwen 3.8), multimodal (Gemma 4), and the deepest reasoning in Ultra Deep (Kimi K3). The fleet is audited every 30 days against public benchmarks and updates itself automatically across the whole network.

Your GPU has value.
The reef proves it.
Korai owns no datacenter. The network is made of machines like yours: a Mac, a tower with an NVIDIA card. You host open models, you get paid per second of compute.
The app detects your hardware, loads the right models, and the network does the rest. Requests arrive without the requester's account or IP address, but you can read the text your machine processes.
Simple pricing,
built for Europe.
Four tiers, from a free no-signup entry to intensive professional use. These are the tiers in effect, not a projection.

Korai names are stable: the backend is always the best open-weight model available, the catalog rotates.
Korai Current: up to 27% cheaper than equivalent market API pricing on input, with EU sovereignty and privacy on top.
