I’m building a tool to fix my broken anime history (and sync it to MyAnimeList)

I realized something kind of annoying recently — my MyAnimeList is completely wrong.

I’ve watched a ton of anime across different platforms, but never kept it updated properly. At this point it’s missing entire shows, wrong episode counts, and just generally useless.

So I started building a small tool for myself:

The idea is simple:

• paste or upload your watch-history page (HTML)
• the app parses it locally
• figures out what you’ve actually watched
• groups everything into real anime progress
• matches it to MyAnimeList
• lets you review everything
• then updates your MAL safely

No scraping, no extensions — just using your own data.

Right now I’m working on:

• Crunchyroll HTML import
• parsing + aggregation
• MAL matching + preview

The goal is basically:

messy watch history → clean, accurate MAL

I’m building this pretty quickly and sharing progress as I go.

Curious if anyone else has this problem or if I’m the only one who let their MAL fall apart over time.
