Brevis — Free AI Page Summarizer

About

Stop scrolling. Start understanding.

Brevis turns any web page, article, or blog post into a clear summary in one click — using Chrome's built-in Gemini Nano AI that runs entirely on your device. No API key. No sign-up. No subscription. No data ever leaves your browser.


✨ Why Brevis

🔒100% Private — All AI runs locally with Chrome's on-device Gemini Nano. Your data never touches a server. Zero telemetry. Zero tracking.
⚡ Free Forever — No subscription, no token limits, no account, no credit card.
🚀 One-Click Speed — Press Alt+S or click the toolbar icon to summarize the active tab instantly.
🌍 Works In Your Language — Auto-detects page language and writes the summary in the SAME language. Interface available in 5 languages.


📑 Three Ways to Read Faster

1) SUMMARY — Get the full page in 6 styles:
   • TL;DR (1 sentence)
   • Quick (3–5 bullets)
   • Standard (8–12 bullets)
   • Detailed (in-depth bullets)
   • Academic (Intro–Method–Findings–Conclusion)
   • Comprehensive (Map-Reduce for long documents)

2) ACTIONS — Extract real to-dos from articles, meeting notes, or guides. Each task ships with a priority tag (Urgent / Important / Optional) and an estimated time.

3) INSIGHTS — Surface the "I didn't know that" moments. Brevis highlights surprising, overlooked, or critical information you'd otherwise miss on a quick read.


🎯 Built for Real Work

• News articles — Skim today's headlines in seconds
• Research papers — Pull the abstract, method, and findings
• Long blog posts — Get the thesis without the fluff
• Documentation — Find what you need without Ctrl+F-ing the whole page
• Forum threads — Get the consensus from a long discussion
• Product pages — See real specs and reviews at a glance
• Meeting notes — Turn transcripts into action items


🔐 Privacy You Can Verify

Brevis is built on Chrome's on-device Gemini Nano. The AI model is downloaded once by Chrome and runs locally in your browser. Brevis itself makes ZERO network requests beyond loading its own files. No telemetry. No analytics. No tracking pixels. Your page content, summaries, and history stay on your device — always.


🌐 5 Languages, Intelligent Routing

Interface: English, Türkçe, 日本語, Español, Deutsch.

Summary engine: English / Japanese / Spanish pages use Chrome's native Summarizer API for speed. Other languages (Turkish, German, French, and more) run through Chrome's Language Model API — same on-device Gemini Nano, broader language coverage.


⚙️ How It Works

1. Open any web page
2. Click the Brevis icon (or press Alt+S)
3. Choose Summary, Actions, or Insights
4. Pick your style (TL;DR, Quick, Detailed…)
5. Hit Run — Gemini Nano processes the page locally

For long documents, Brevis automatically switches to Map-Reduce: it splits the text into sections, summarizes each in parallel, then merges everything into one clean meta-summary.
