BiliMind

About

BiliMind is a Chrome extension that instantly generates interactive mind maps from Bilibili
  video subtitles, helping you grasp the structure of any video in seconds.

  HOW IT WORKS
  1. Open any Bilibili video page (bilibili.com/video/*)
  2. Click the BiliMind icon in your toolbar to open the side panel
  3. Sign in with your Google account
  4. Add your SiliconFlow API Key in the profile settings
  5. Click "Generate Mind Map" — BiliMind extracts the subtitles and uses DeepSeek-V3 AI to build
  a structured mind map
  6. Explore, zoom, and export the result

  KEY FEATURES
  • AI-powered mind maps — powered by DeepSeek-V3 via SiliconFlow, turning raw subtitles into
  clean, hierarchical maps
  • Single-color branch style — clean, readable tree layout instead of the default rainbow colors
  • Subtitle viewer — read, copy, or refresh the full subtitle text at any time
  • Auto-load history — previously generated maps reload automatically when you revisit the same
  video
  • Export to Markdown — save your mind map as a .md file
  • Resizable side panel — drag to adjust the panel width
  • Fullscreen mind map — expand the map to fill the panel for easier reading
  • Token usage stats — track how many AI tokens each generation consumed

  YOUR DATA & PRIVACY
  • Your SiliconFlow API Key is stored only in your local browser (chrome.storage.local) and is
  never sent to our servers
  • Subtitles are fetched directly from Bilibili's public API and sent to SiliconFlow solely to
  generate your mind map
  • We store only the generated mind map and basic account info (email, name, avatar from Google
  sign-in)
  • Full privacy policy: https://bilimind.vercel.app/privacy

  REQUIREMENTS
  • A free SiliconFlow account and API Key (siliconflow.cn) — the extension uses your own key so
  you control your costs
  • A Google account for sign-in
  • Works only on bilibili.com/video/* pages
