For every article you starred and forgot.

TL;DR is a Chrome extension + AI pipeline that automatically summarizes any article you save — and reads it back to you like a podcast. Save it once. Get the summary. Listen on the go.

Built at DiamondHacks 2026, powered by Browser Use.

• One click — save any article from Chrome with the extension
• AI browsing agent — Browser Use navigates the live page like a human, extracting the full content
• Gemini summarization — clean, concise 3-5 sentence prose summary, no bullet points
• Audio version — full text-to-speech MP3, ready to listen like a podcast
• Email notification — get pinged the moment your summary is ready
• Live dashboard — your digest, stats, and audio player, all in one place

Works on articles, PDFs, research papers, news sites — anything.

Dashboard shows summary + audio player

• Stats — total saved, summarized, time saved, audio ready
• Article cards — summary, source, read time
• Audio player — play/pause, skip ±15s, scrub bar
• Mode toggle — Text, Audio, or Both
• Email notifications — register once, get pinged every time

• Some sites (e.g. Medium) require Cloudflare to auto-resolve — this adds a few seconds
• Gmail SMTP requires an App Password, not a regular password
• Gemini free tier has rate limits — use a billing-enabled project for heavy use
