Siftly is a self-hosted Twitter/X bookmark manager built with Next.js, TypeScript, SQLite, and Tailwind CSS.

It processes bookmarks via a 4-stage AI pipeline: entity extraction from tweet data, vision analysis of media for 30-40 tags per image, semantic tagging for 25-35 tags per bookmark, and categorization into 1-3 categories with confidence scores. Users import bookmarks using a bookmarklet or console script, access AI search, interactive mindmaps, filtered views, and exports, with authentication prioritizing Claude Code CLI or Anthropic API keys.
