About Circaetus
Circaetus keeps your tabs under control. Like the short-toed snake eagle it is named after, it
hovers, watches, and only acts when it is sure.
STOPS DUPLICATE TABS
Open a page you already have open and Circaetus puts your existing tab where the new one was
about to land, then closes the new empty one. Your original keeps its scroll position, history
and anything you had typed. Nothing you could lose is ever closed. Pinned tabs, tab groups and
a list of sites you allow (webmail, docs…) are respected, and one shortcut duplicates a tab on
purpose.
FILTERS THE REST, NO AI NEEDED
One-click sweeps for duplicates, stale tabs, never-read tabs, disposable pages and noisy tabs.
Everything you close through Circaetus is stashed first, so you can bring it back.
GROUPS TABS FOR YOU
• By theme, with rules you can edit.
• By work session: tabs you opened from one another, or back to back.
• Suggested groups by origin or by website. Nothing is applied until you review and name it.
RESCUES FORGOTTEN VIDEOS
Collects the YouTube tabs you abandoned into a real playlist on the account you are already
signed into. No Google project, no API key.
TURNS TABS INTO TODOS
Capture a tab as a TODO in an Eisenhower matrix, in bulk if you like. Export as JSON or
markdown, or hand them to the Penduline extension if you use it.
HANDS THE AMBIGUOUS ONES TO CLAUDE, WITHOUT AN API KEY
Copy a compact snapshot of your tabs, paste it into any Claude session you are already signed
into, then paste the plan back. You preview every step before anything happens.
PRIVATE BY DESIGN
• Everything stays on your device. No account, no analytics, no tracking, no remote code.
• No access to page content: no content scripts and no host permissions.
• Nothing leaves your browser unless you copy it yourself.
SIDE PANEL + DASHBOARD
The toolbar icon opens a side panel that stays open while you browse. A full dashboard gives
you the tab table, groups and the TODO matrix (Alt+Shift+T).
