As answered by people managing Twitter Mark and Splitwise.
Twitter Mark's answer
Twitter Mark is local-first: synced X/Twitter bookmarks and likes, indexes, tags, settings, and history stay in your browser's local database instead of a hosted archive. Sync is read-only—it never posts, likes, follows, or removes items for you. It combines incremental/full sync, search, filters, custom tags, resumable background jobs, and JSON backup/restore in one Chrome extension.
Twitter Mark's answer
Choose Twitter Mark if you want a private, user-controlled archive rather than another cloud feed or X automation tool. It handles both bookmarks and likes, keeps archive data on your device, provides read-only and resumable sync, and lets you export and restore JSON backups. A useful free tier is available, while Pro Lifetime is a one-time purchase with no monthly expiry.
Twitter Mark's answer
Twitter Mark is for people who deliberately save useful posts on X and later struggle to retrieve them—researchers, creators, developers, students, and other knowledge workers who want a personal reference library. It especially suits privacy-conscious users who prefer local storage, read-only access, search, tagging, and portable backups.
Twitter Mark's answer
Twitter Mark began with a simple problem: saving posts on X is easy, but finding them again later is not. It was built to turn bookmarks and likes into a fast, searchable local archive while preserving privacy and user control. The result is a read-only Chrome extension with tagging, filters, resilient sync, and JSON backup and restore.
Twitter Mark's answer
Twitter Mark's Chrome extension is built with TypeScript, React, WXT, and Dexie on top of IndexedDB. It uses a Manifest V3 browser-extension architecture and stores archive data locally. The commercial companion site uses React and TypeScript on Cloudflare Workers, with Stripe handling one-time Pro purchases.
