X Search

X Search
"Browser extension that lets you full-text search anyone's X (Twitter) posts.
X's built-in search is unreliable and limited. This fixes that by indexing posts locally in your browser."

How it works

1. Visit any X profile
2. Click "Index" in the extension popup to scroll through and capture all posts
3. Search across all indexed profiles or within a single profile

Posts are stored locally in IndexedDB using Dexie.js. Nothing leaves your browser.

Features

• Full-text search across all indexed profiles
• Per-profile search with result highlighting
• Profile management (view indexed count, delete profiles)
• Pause/resume/re-index controls
• Works with X's virtual DOM and lazy-loaded content

Stack

• Plasmo (browser extension framework)
• React + TypeScript
• Dexie.js (IndexedDB wrapper)
• @tabler/icons-react
