TLDR - Page Summarizer

About

TLDR instantly summarizes any web page — articles, news, blog posts, or even pages with multiple posts and feeds.

Click the extension icon, and a dedicated tab opens with a streaming TLDR summary. No waiting — text appears in real-time as it's generated.

Want to dig deeper? Ask follow-up questions right there in the built-in chat. The AI has full context of the page and will respond in the same language as your summary.

KEY FEATURES

* One-click summarization — click the icon and the summary starts immediately
* Streaming output — see the summary as it's being written, not after
* Follow-up chat — ask questions about the page content in a conversational interface
* 10 languages — summarize in English, Chinese, Spanish, Hindi, Arabic, French, Portuguese, Russian, Japanese, or German. Or keep the original language
* Model selection — choose between GPT-5.4, GPT-5.4 Mini, GPT-5.4 Nano, GPT-4.1 family, and o3-mini
* Smart extraction — works with single articles, news feeds, and multi-post pages alike
* Localized interface — the entire UI is translated into all 10 supported languages
* Privacy-first — your API key stays in your browser, no third-party servers
