The safe way for AI to act in your accounts
Daiku gives the AI people already use a browser of its own, logged in to their sites. Only the person's passkey can say yes to a send, a payment or a delete.
What we believe
- 1
AI apps can talk. Next, they have to do things in people's real accounts.
- 2
Most of that work sits behind logins, on sites with no way in but a browser.
- 3
People want the help, but not the risk.
- 4
Daiku gives each person a private browser that their AI apps can share, with approvals only that person can give.
- 5
It works with AI apps instead of competing with them, so it grows as they grow.
Why now
- Dec 9, 2025
The open standard AI apps use to add tools moved to the Linux Foundation, backed by Anthropic, OpenAI, Google, Microsoft and AWS. One link now works across AI apps.

xAI, Meta and OpenAI each launched AI that works for people in a cloud computer of its own. Each one lives inside its maker's own app.

Why Daiku wins
Neutral
It works with Claude, ChatGPT, Claude Code, Cursor, Codex and more, while each big platform pushes its own.
A yes no AI can fake
Approval is the person's passkey, bound to the exact action and to what goes out.
Rules only get stricter
An AI can make Daiku stricter, never looser. Looser needs the person.
Built for Europe
Each person's browser and log are stored in the EU. Daiku puts browsers in Germany, France, the UK, Switzerland and 7 more countries. Some new assistants aren't offered in Europe yet.

Cheap to run
Each browser sleeps when no one uses it, so cost follows use.
