Tern is a Mac browser with an agent in every Space. Ask for what you need; it opens the pages, compares them, and checks with you before it acts.
One window. Every part of your life.
A trip, your work and your reading each get a Space, with their own tabs, sign-ins and agent.
Switch, and everything follows.
Tabs, accounts and the agent change with the Space. Nothing leaks between them.
Each Space keeps working.
Its agent carries on while you are somewhere else, and tells you when it's done.
Ask, and it answers in your Space.
The agent reads the pages you have open, and opens more when it needs to.
It compares, so you don't have to.
Two day trips, how to get there, how long they take. One clear answer.
Nothing happens until you say so.
Sending, buying, booking: the agent asks first. Passwords and card numbers it never types.
Small things, done beautifully.
Six of them, and every one is a real part of Tern.
Keep what matters pinned.
Pinned tabs and folders sit at the top of each Space. Close one and it sleeps in its place.

Trackers and ads, blocked.
Known trackers and ad servers can't load, in every Space. If a site misbehaves, turn it off for that site from the shield.
Checked on your Mac, from the EasyList and EasyPrivacy lists.
Every Space looks like itself.
Its own colour and icon, and when nothing is open, its own scene.
Your browsing stays on your Mac.
History
Kept on your Mac, and searchable from the command bar.
Sign-ins
Kept apart for every Space. Deleting a Space deletes them.
The agent
Sends the pages it reads to Anthropic, only when you ask.
Trackers and ads
Blocked in every Space. The list comes with Tern, so pages are checked on your Mac.
Crash reports
Off until you turn them on. No pages, addresses or anything you typed.
Analytics
None. No account, no ads, no tracking.
