Hi Product Hunt! 👋

I’m the maker of PostHistory.

We’ve all experienced that annoying moment on X: you’re halfway through reading an interesting post, the feed suddenly auto-refreshes, and the post disappears forever before you had a chance to bookmark it.

I built PostHistory to solve this problem once and for all — without compromising privacy.

⚡ How it works:

Enable the lightweight PostHistory Safari Web Extension on your iPhone. Whenever you browse x.com in Safari, posts that appear on your screen are automatically saved to your local history log.

✨ Key Features:

• 🔍 Instant Search & Filters: Find any post you saw earlier by keyword, @handle, Today, Favorites, Images, Videos, or Articles.

• 🔒 100% On-Device Privacy: Everything stays inside a local SQLite database on your iPhone. Zero external servers, zero tracking, and no account login or X API needed.

• 📱 Cleaner Mobile Safari UI: Automatically hides intrusive "Open in App" banners on mobile web.

• 🏷️ Custom Tags & Export: Organize favorite posts with custom tags and export your data to JSON/CSV anytime.

💎 Pricing:

PostHistory is free to use (stores up to your latest 100 viewed posts, with favorited posts protected forever).

For power users, PostHistory Pro ($0.99/mo, $6.99/yr, or $11.99 one-time lifetime) unlocks unlimited history storage, promoted post filtering, calendar date range search, and smart recording rules.

I’d love for you to try it out and let me know what you think or what features you'd like to see next! 🙏
