## 總覽

Lexal is a free Chrome extension that turns Gemini into an on-demand critical-thinking companion while you browse. Highlight or select text, right-click, and you can fact-check a claim, scan an article for bias, generate a quick summary, or launch a structured debate that argues both sides of a topic. Replies come back in your browser's language.

## 價格與方案

Free. Lexal is a standalone wrapper that runs on your own Google Gemini developer API key and does not charge for tokens; you only pay Google if you exhaust the free Gemini credit allowance.

## 關鍵功能與能力

- **One-click fact checking:** Select any statement and get Gemini to verify whether a specific claim holds up, right inside the page you are reading.
- **Bias detection:** Scan an article and have the model call out framing, slant and potential bias so you can read more critically.
- **Summarise / TLDR:** Condense long articles, threads or documents into a short TLDR you can skim in seconds.
- **Two-sided LLM debates:** Generate balanced, well-reasoned arguments for and against a topic to stress-test your own position.
- **Browser-language output:** Outputs are returned in your browser's language, so the tool fits naturally into a multilingual browsing session.

## 主要使用情境

- **Check claims before sharing (Everyday reader):** Verify questionable claims in articles and posts before sharing them, using the fact-check function on selected text.
- **Critique news framing (Student or researcher):** Run quick bias checks and summaries to compare how different outlets frame the same story.
- **Stress-test an argument (Writer or debater):** Generate for-and-against arguments on a topic to test your reasoning before writing or debating.
- **Skim long content (Knowledge worker):** Pull a fast TLDR from long documents and web pages without leaving the browser tab.

## 優勢

- Completely free, with no token markup or subscription
- Runs on your own Gemini API key, so there is no third-party data middleman
- Right-click workflow keeps you inside the page you're reading
- Combines four distinct reading aids — fact check, bias check, summary and debate — in one small extension
- Depends only on Gemini, so only one API key is needed

## 限制

- Tiny user base and no reviews, so reliability feedback is limited
- Requires you to obtain and manage your own Gemini API key
- Last updated in July 2024, so it may not track the newest Gemini models
- Right-click only workflow — no persistent sidebar or full-page interface
