PDF notes that remember their page, and hand off to your AI

3 followers

Pull passages out of any PDF onto a notes canvas, write what you think, and link ideas with labels like "supports" or "contradicts". Click any note to jump back to its exact page. Export the whole map as AI-ready Markdown and give it to ChatGPT or Claude with the PDF. Free, open source, no account, and nothing leaves your browser.
