How TabMerger compares

A fair, side-by-side look at TabMerger and 9 other tab managers: what each one does, and what it costs.

Checked on Nov 5, 2026

Sync the server can't read

Every synced group is end-to-end encrypted, always. Your tabs are locked with a key only your devices hold.

AI that does the filing

Group a mess of tabs, name a group, or get a one-line summary of a page. With Pro AI or your own key.

Move over in a minute

Copy your OneTab lists into a .txt file and import it from Settings → Data: each list becomes a group. Bookmarks HTML and JSON work too.

Switching from OneTab?

Your lists come across as groups, titles and all. Nothing leaves your browser.

Add to Chrome — It's Free

In OneTab, open Export / Import URLs and press Copy to clipboard.
Paste it into a plain-text file (Notepad, or TextEdit set to plain text) and save it as .txt.
In TabMerger, open Settings → Data, press Import and choose the .txt file.
Confirm. Each OneTab group becomes its own group, named “Imported 1”, “Imported 2” and so on.
Coming from another tool? Export your bookmarks as HTML, or a JSON file, and import that the same way.
