Too much content, too little time. The AI Summarizer bookmarklet extracts the most important sentences from any webpage in seconds.
It uses extractive summarization, meaning it only selects sentences already in the article. No hallucinated text, no external servers, no API keys.
How It Works #
- Sentence extraction breaks text into individual units
- Word frequency analysis ranks sentences by importance
- Position scoring boosts earlier sentences slightly
- Top results become your summary
What the Panel Shows #
- Word count and estimated read time
- Condensed summary with key sentences
- Top 3 highlighted sentences
- One-click copy for summary or full output in Markdown
Best Results #
Works best on articles with 500+ words and clear paragraph structure. Shorter content may return most of the original text.
Everything runs locally in your browser. Nothing leaves your machine.
