Free AI Summarizer - ChatGPT, Claude, Gemini 作成者: futamura

Free AI Summarizer extracts the main content of the page you are reading and hands it to the AI chat service of your choice, together with a summarize prompt. There is no API key and no account for this extension: it uses the AI service's own website in a new tab, so you need to be signed in to that service if it requires it.

How it works
1. Open a web article or a YouTube video.
2. Click the toolbar button (on Firefox for Android: menu → Extensions; on desktop you can also right-click the page) and choose an AI service.
3. A new tab opens the service with the article and your prompt already sent.

Supported AI services
ChatGPT, Claude, Gemini, Google AI Studio, Grok, Perplexity, DeepSeek, Kimi (kimi.ai), Qwen

Supported content
- Web articles, blog posts and general web pages
- YouTube video transcripts
- PDF files are not supported in the Firefox version: Firefox opens PDFs in its built-in viewer, where extensions cannot run.

Features
- A customizable prompt for each AI service, and model selection where the service allows it
- Copy the extracted article to the clipboard
- Context menu entries (desktop)
- Settings in the Firefox sidebar on desktop, in a tab on Firefox for Android
- Dark and light themes

Privacy and data
- The extension has no server of its own and does not use analytics or tracking.
- Extracted articles and your settings are stored locally in your browser.
- When you choose an AI service, the page title, URL and extracted text are sent to that service, under your own account, and are handled according to that service's privacy policy. Nothing is sent until you choose a service.
