Description

You merged some notes, re-imported a deck, or finally fixed a card you'd been failing for months — but Anki still remembers every single wrong answer. The Reset button puts a card back in the new queue, yet its review log stays in your collection forever, quietly feeding your stats and FSRS. Clean History deletes that log for good, so a card really can start from zero. 🧹 Clean History gives Anki the clean slate it's missing. 🧹 Erase the review log of the cards you pick — they become genuinely new, not just rescheduled. 🗂️ Clear the entire collection in one go from the Tools menu, including leftover entries from cards you deleted long ago. 🖱️ Works right from the card browser: select, right-click, done — any deck, subdeck or filtered deck. 🛡️ Makes a backup automatically before every run, and always tells you the exact number of cards it will touch. ⚡ Handles collections with hundreds of thousands of cards without freezing Anki, with a real progress bar. 🌍 Speaks your language: every button and warning reuses Anki's own translations, plus 41 languages for the rest. ⚙️ Two plain checkboxes in a normal settings window — no JSON editing, ever. HOW TO USE Open the card browser (Browse) and select the cards you want wiped. Right-click and choose "Delete review history…". Confirm — a backup is created first, then the cards go back to new. For everything at once: Tools → "Delete review history (Whole Collection)…". SETTINGS Tools → Add-ons → Clean History → Config: choose whether unstudied cards keep their original queue position, and whether repetition and lapse counts are reset. COMPATIBILITY Tested on Anki 25.09 (Qt6) on Windows; it uses only cross-platform APIs, so macOS and Linux reports are very welcome. Note that deleting review logs cannot be undone with Ctrl+Z and requires a one-way sync afterwards — Anki warns you before it happens. CHANGELOG v1.0.0 — 2026-07-14 — Initial release. Free forever, and open source (AGPLv3). If this add-on saves you time, you can support its development: 👍 Enjoying it?
