What is Instant Summary
Summarize the active article page locally with zero external API calls. Summarize any article in one click — without your data ever leaving your browser.
Instant Summary - Local AI uses AI to generate concise summaries of articles, blog posts, and news — all processed locally on your device. No cloud servers. No API keys. No subscriptions. Your reading habits stay yours.
WHY LOCAL MATTERS
Most summarization tools send your content to external servers. That means someone else sees what you read, processes your data, and stores it on infrastructure you don't control.
Instant Summary runs the AI model directly in your browser. Your article text never leaves your device. Period.
