Post Library

Save your own saved Threads posts into a private, searchable library on your device — offline, organized, yours.

I built Post Library because my Threads saved list turned into a black hole. Hundreds of posts I "saved for later", and I could never find any of them again. And if a post gets deleted or the account goes private, it's just gone. Post Library backs them up to your own computer. Press Start and it opens your Saved list, goes through the posts one by one, and keeps the text, the best replies, the photos and the videos. After that the library is yours: browse it offline, search the full text, filter by category or author, play the videos right there. A few things I cared about while building it: Everything stays on your machine. No account, no server, no analytics. I never see your data — there is literally nowhere for it to be sent. It only reads your own saved posts. You have to be logged in to your own Threads account, and it simply reads the same Saved list you already see. The AI tagging is optional and runs on your own API key (Gemini or Agnes AI). Turn it on and it sends the post text to the provider you picked, which writes back a category, a few tags and a one-line summary. The key is stored on your computer and goes nowhere except to that provider. OCR is optional too and runs entirely on your device, so the text inside screenshots becomes searchable without any image being uploaded anywhere. You're not locked in. One click exports everything as JSON, and each scrape also writes a plain backup.html that opens in any browser — no extension needed, handy if you ever stop using this one. By default it scrapes slowly with random pauses, so it never hammers Threads. This is an unofficial tool and is not affiliated with, endorsed by, or connected to Meta Platforms in any way
