Key features
Instant AI summaries, multilingual support, and clickable timestamps — all delivered in Chrome's side panel without interrupting your browsing.
Instant video summaries
Sumbox uses parallel processing to summarize even hour-long YouTube videos in 8–10 seconds. The transcript is split into chunks and processed simultaneously, delivering a TL;DR, full summary, and formatted script all at once.
Clickable timestamps
Video transcripts include timestamps formatted as [MM:SS] that link directly to the corresponding moment in the video. Clicking a timestamp seeks the YouTube player to that exact time — ideal for quickly referencing specific parts of a long video.
Dark mode
A full dark theme transforms the entire interface while maintaining readability. Your preference is saved automatically and persists across sessions so you never have to set it twice.
Works on paywalled articles
Sumbox also summarizes paywalled articles via experimental client-side DOM extraction.
Web article summaries
Sumbox works on any web article, blog post, or news page. It uses Apify to scrape and clean page content, stripping ads and navigation, then delivers a TL;DR and full summary through Google Gemini.
14 languages supported
Get summaries in your preferred language regardless of the source content. Sumbox supports 14 languages including English, Spanish, French, German, Italian, Portuguese, Polish, Dutch, Russian, Chinese, Japanese, Korean, Arabic, and Hindi.
Summary history
Revisit any past summary at any time without re-processing the content. Your summaries are saved locally and always available — perfect for picking up where you left off.
Chrome side panel
Sumbox lives in Chrome's side panel — always accessible alongside your content without covering the page you're viewing. Open it with a single click and get summaries without interrupting your browsing.
Export & share
Export summaries in Markdown, HTML, Rich Text, Plain Text, or JSON to fit your workflow. Use the Copy and Share buttons to instantly send any section via email, messaging apps, or social media.
