LightMark

Save text highlights quietly as you browse. Export your clips in one click.

LightMark is a lightweight, local-first web clipper. Keep useful text, images and HTML5 video frames while you continue browsing, then export a clear card-style document. Quiet text capture Select text and click the floating capture button, or press Alt+S. Choose the destination project directly from the toolbar to save the selection there. Each clip keeps its page title, source URL and capture time. Web images and video frames Right-click an image to save it to LightMark, or use its floating capture control. Capture the current HTML5 video frame with the video/page title, playback time and a time-positioned page link. A separate user-triggered action downloads a directly accessible video source through the browser. The full video file never enters the notes database or exported document. Readable card exports Export the active project to Word (.docx) or Markdown. Clips stay in chronological order with numbering, clickable source links and timestamps. Word embeds saved images and video stills and includes branded headers and footers. Text line breaks and indentation are preserved. Text-only Markdown is a single .md file; projects with images export as a ZIP containing notes.md and an images folder. Extract and keep both together. Local-first privacy Clips and settings remain in the current browser. No account, developer-server clip uploads, analytics or AI service is required. Fetching an original image or downloading a video contacts the website hosting that media. Browser and device collections remain separate. Projects and language Create projects and preview recent clips in a simple card-style popup. Choose Auto, 中文 or English; the interface and exports follow your selected language. Limits Browser internal pages, store pages and other protected pages may block extensions. A website may also prevent video frame capture. Video source downloads support directly accessible HTTP(S) files; Blob URLs, DRM-protected media and .m3u8/.mpd segmented streams are not supported as complete video downloads. General time-positioned page links require LightMark in the destination browser and the same video on the page; native YouTube time links use the site's timestamp parameter. Use the floating button or change the extension shortcut if Alt+S conflicts with another app. What's new in 0.3.0 Clickable source URLs; direct project selection from the capture toolbar; web image collection; HTML5 video frame capture with timestamps; and separate direct-source video downloads, with existing project data preserved.
