The web, open on your terms. Private apps and an AI agent, built into your browser.
Apps run on your device and your data stays yours. The agent asks before the steps that matter. Keep what you find and find it again.
Free to use. Releases are listed on the Download page as they become available. AI tasks use a model you choose, on your device or from a provider you connect.

Approval needed

Writing to your Library needs your approval the first time this task runs.
AI agent
Let your browser help with the work.
Give the agent a task in plain words. It reads the pages you have open, uses the apps you have installed and works in your Library. A step that changes something needs your approval.
How approvals work Save a task and run it again- You stay in charge
- Steps that change, send or delete need an approval from you, given once or as a rule you set. Payments and passwords are always yours. Stop any task at any time.
- It works where you work
- Open tabs, installed apps and your Library are the tools. Files are used only when you choose them.
- Your choice of model
- Run a model on your device or connect a provider. Each cloud provider needs your consent before anything is sent.
