## 概览

Auto Highlight is a free, open-source Chrome extension that automatically highlights the most important sentences in an article using term-frequency analysis, giving you a fast tl;dr without leaving the page.

## 定价与套餐

Free. Auto Highlight has no paid plans, no subscription and no in-app purchases — it is distributed at no cost through the Chrome Web Store.

## 关键功能与能力

- **One-click page highlighting:** Click the highlighter icon in the address bar and the extension immediately marks the sentences that carry the article's core meaning.
- **Adjustable coverage on repeat clicks:** Each additional click increases or reduces how much of the article gets highlighted, so you can dial coverage up or down to taste.
- **Term-frequency sentence ranking:** Important sentences are ranked from term frequencies across the full article, a lightweight extraction-based summarization technique.
- **Visual ink-level indicator:** The toolbar icon visually shows "ink" running out as more highlighting is applied, giving instant feedback on current coverage.
- **Open source and privacy-first:** The source code is published on GitHub, the privacy policy states no data is collected or transmitted, and options stay local.

## 主要用例

- **Skim long articles in seconds (Readers):** Skim the essential sentences of a long news or blog piece before deciding whether to read it in full.
- **Fast source triage (Researchers & students):** Speed up literature and source scanning by jumping straight to the sentences carrying the main information.
- **Quick gist extraction (Writers & analysts):** See the load-bearing sentences of a competitor or reference article quickly to grasp its arguments.
- **Data-free reading aid (Privacy-conscious users):** Users who want short control over consent and analytics can enjoy a reading aid that never transmits data remotely.

## 优势

- Instant tl;dr directly on the page — no copy-pasting into another tool

- Last updated March 2024 and only rated 3.6, reflecting some inconsistent page results
- No native support for PDFs or images — it is built for HTML article text
