Loop back before you forget

SM-2 spaced repetition with cloze, decks & stats — no cloud.

Free · Local-first · No account required

CardLoop turns anything worth remembering into flashcards and schedules each review for the moment you're about to forget — using the proven SM-2 algorithm Anki made famous.

It needs no account, no cloud and no AI: every card lives only in your browser. Capture anywhere by selecting text on a page and clicking “Add to CardLoop.”

Choose classic front/back or cloze deletions ({{c1::like this}}) with a live Q/A preview, grade Again/Hard/Good/Easy with next-interval previews, and organise with coloured decks, tags, search and state filters.

Track progress with a review heatmap, day streak, retention %, a card-maturity breakdown and a 7-day forecast — and own your data with JSON backup and Anki/Quizlet/CSV import.

Privacy

Why each permission is needed

CardLoop asks for the minimum and explains every one.

storage
Saves your decks, cards, review history and settings locally via chrome.storage. Nothing is sent anywhere.
sidePanel
Shows the CardLoop hub (due counts, decks, quick-add, capture inbox) in Chrome's side panel beside any tab.
contextMenus
Adds a right-click “Add to CardLoop” item so text you select can become a card. Only the text you select is used; CardLoop does not read page contents.
alarms
Periodically recomputes the number of cards due today shown on the toolbar badge. No network activity.
