AI Highlighter

Highlight the important AI news on any page with your own Claude, GPT or Gemini key. Learns your taste. Private & local. AI Highlighter finds the genuinely new and important AI-world sentences on any web page and paints them right on the page in bright color — then gives you a skimmable reading list and a short briefing in the side panel. Built for people who follow AI news every day.

WHY IT'S DIFFERENT

• On-page highlights — the real sentences, marked in color where you actually read them.
• Skim-first side panel — each item leads with a one-line "why it matters"; click it to jump straight to that spot on the page.
• Page briefing — a 2–4 sentence summary of what's new for AI on the page.
• Learns your taste — 👍/👎 each highlight; your feedback distils into editable KEEP / SKIP rules that sharpen every future scan.
• Bring your own model — Anthropic Claude, OpenAI GPT, or Google Gemini. Your key, your choice, with a built-in "Test key" check.
• Any language — summaries follow the page's language automatically, or force one (e.g. always German).
• Per-tab + pop-out — the panel matches the tab you're on; pop it into its own window for screen-sharing or a second monitor.
• Persistent — highlights are saved per URL and repaint on reload, with no re-scan and no extra cost.

PRIVATE BY DESIGN

• Manual only — nothing is sent anywhere until you click the icon, press the shortcut, or hit Rescan.
• Your API key is stored only in your browser, on your device. It is never synced, never sent to us, and we run no server.
• When you scan, the page text goes straight from your browser to the AI provider you chose — and nowhere else.
• No account, no analytics, no tracking.

HOW TO USE 1. Install, open Options, pick a provider and paste your own API key (from Anthropic, OpenAI, or Google), and click Test key. 2. Open an article and click the toolbar icon (or press Alt+Shift+H). 3. Skim the side panel, click any item to jump to it on the page, and 👍/👎 to teach it your taste.
