MarkMind is a web highlighting & notes tool that helps you capture, organize, and revisit ideas on any web page. ★ Highlighting & Annotation One-click mark on text selection, 6 colors. Supports Markdown notes with live preview. Floating toolbar is draggable & resizable with built-in copy/paste shortcuts. All popups support 8-direction drag-resize and 4 position modes (follow / left / sidebar / center). Works in iframes (Lanhu, Axure, etc.) and chunked streaming pages (CNKI, etc.). One-click copy mark link — opening it auto-scrolls to the corresponding position. ★ Mindmap (Outline) AI induces a knowledge-point hierarchy from the page body, and marks attach as leaves under the best-matching point — revealing the full article structure and where your marks sit. Nodes can be dragged to rearrange; positions and viewport are auto-saved. Marks can be linked via relations (argument / counter / extend / define / contrast — 5 semantic types), distinguished by line style and arrow. Drag a relation edge directly to adjust its curve; hovering shows the relation type name. ★ Organize & Filter Global grouping supports multi-level paths (e.g. "Dev/Frontend"). Marks have a type (mark / bookmark) and group field, with automatic migration of old records. Sidebar filters by page / site / color / group plus full-text search. Split-view divider is draggable. List auto-paginates (50 per page). Star-to-pin-to-top. Batch delete / export / share / set group. ★ Import & Export Import browser bookmarks (Netscape HTML) — auto-converted to marks by group path. Export marks as JSON (full data) or importable HTML bookmarks. ★ Cloud Sync (optional, user-controlled) Sync via your own GitHub or Gitee Gist. Off by default. Token stays local only. Sync scope is selectable (marks / AI config / style settings / mark settings — independently checked). ★ Share (optional) Generate a public Gist share link for selected marks. Others import by pasting the share code — no token needed. Auto-reuses / updates existing shares to avoid duplicates; share history syncs across devices. ★ AI Assistant (optional — requires user-configured API key) Bring your own key and endpoint; supports any OpenAI-compatible API. AI requests go directly from your browser to your configured provider — the developer never touches any data. Available AI actions: - AI Translate: translate marked text to a target language - AI Tags: auto-generate structured tags from mark content - AI Reference: AI interprets the page body and your notes, then extends the thinking - AI Tutor: evaluates note accuracy, points out errors, supports follow-up dialogue All AI entries can be turned off with a single master switch. ★ Customization Light / Dark / System themes. Supports Chinese, English, Japanese, Korean, Russian. Toolbar and mark-detail popup positions are customizable. ★ Privacy Local data is stored only in the browser's IndexedDB and chrome.storage.local. The developer does not collect, transmit, or sell any user data. See the privacy policy for details. Manifest V3 · Vanilla JavaScript · IndexedDB · CSS custom properties · esbuild
