Checkpoint

Checkpoint is a side panel extension that tracks your reading progress for manga, manhwa, and manhua across any website you read on. Open the side panel, navigate to what you're reading, and hit +. Checkpoint auto-detects the title and chapter from the page, searches ComicK first (with AniList and MangaDex as fallbacks), grabs the cover art and metadata, and saves it to your local library. Re-add a title at a higher chapter and your progress updates automatically — it never goes backwards. Everything is stored locally on your device. No accounts, no tracking, no analytics. TRACKING & PROGRESS — One-click tracking with automatic title and chapter detection — Smart progress that only moves forward — you can't accidentally lose your place — Continue reading — each title remembers where you were, click Open to jump back — Pin titles to the top of your library, regardless of sort order — Sort by Last Updated, Alphabetical, Chapters Ahead, or Recently Added DISCOVER — Trending — browse what's popular right now on ComicK, filterable by Manga, Manhwa, or Manhua.
