What tl;dr is

tl;dr is a free Chrome extension and web app that turns long content into short AI summaries.

How it works

1. Install the Chrome extension.
2. On any article, YouTube video, PDF, or newsletter, click the tl;dr icon.
3. In a few seconds you get a concise bulleted summary in the side panel.
4. From there you can chat with the summary (ask follow-up questions), copy it, share it as a public page at tl-dr.cc/s/{slug}, or save it to history.

What it summarizes

• Articles — news, blog posts, long-form essays, research write-ups.
• Videos — YouTube videos (reads the transcript).
• PDFs — arbitrary PDF documents opened in the browser.
• Newsletters — Substack, Beehiiv, email newsletters rendered in the browser.

Web app

The web app at tl-dr.cc hosts:

• Individual shareable summary pages at /s/{slug}.
• Trending hubs at /trending/{today,week,month} showing the most-summarized articles across all topics.
• Per-topic trending pages at /trending/topic/{category}/{period}.
• Account, history, and billing for users who upgrade to Pro.

Pricing

• Free: generous daily/monthly summary allowance, all content types supported.
• Pro: higher rate limits, priority processing. Upgrade from the extension or billing page.
