Questions

Simmer is a free Chrome extension that remembers what your tabs were for. It turns a pile of open tabs into a short list of the things you're in the middle of, such as choosing a camera or planning a trip, lets you close a whole task at once, and brings every tab of it back in one click.

Most tab managers ask you to sort tabs into groups, folders or workspaces. Simmer does the sorting itself: it works out which tabs belong together from what opened what, from your Chrome tab groups, and by comparing tab titles on your computer. You don't make groups, write rules or file anything.

Not until you say so. The first run reads your tabs and changes nothing until you press the button. After that, tabs left unused for a day or more can go to the back burner, a whole task at a time, and the first automatic clear always asks first. The active tab, pinned tabs, tabs playing sound, private windows and sites you keep open are never touched.

It is saved before it closes, in Simmer's list on your computer and, if you choose, in your Chrome bookmarks. Nothing is dropped to make room. Every action is listed under Recently with Undo.

Open Simmer's side panel from the toolbar and press Bring back on a task: every tab reopens together, in its group. You can also search all your tabs, saved tabs and bookmarks from the side panel, or type sm and a space in Chrome's address bar.

No. Mail, chat and calendars stay open by themselves, and you can keep any site open. Pinned tabs always stay.

Yes. Everything Simmer does is written down under Recently, in plain words, with Undo next to it.

No. There's no account and no Simmer server. Your tabs and everything Simmer saves stay in Chrome on your computer. The model that compares tab titles is part of the extension and runs there. Network features, such as using your own Claude API key, are off until you turn them on.

No. Install it and it works. There is nothing to sign up for.

Not by itself: what Simmer saves stays on the computer where you saved it. If you choose to save put-away tabs to your bookmarks as well, those bookmarks sync wherever Chrome syncs your bookmarks.

Simmer is built for Google Chrome on desktop and installs from the Chrome Web Store.

Yes. The model that compares tab titles works in English and Japanese, and can join an English and a Japanese tab about the same thing.

Yes. Simmer is free, with no account and no ads.

Yes. You can turn on automatic backups, which write a file to Downloads/Simmer on your computer. Chrome asks for permission when you turn it on.

Simmer can put tabs you haven't used for a while to sleep, which lets Chrome free their memory while they stay in your tab strip. Putting a task on the back burner closes its tabs altogether.
