NoteLM.ai YouTube summarizer: paste-a-link notes vs Chrome extension + Gemini API key

Looking for a NoteLM YouTube summarizer, NoteLM.ai YouTube summarizer, or NoteLM youtube transcript notes—without installing a Chrome extension or pasting your own Gemini API key? NoteLM (notelm.ai) publicly markets a YouTube Video Summarizer path centered on a browser extension plus a free Gemini API key you bring yourself, often with chapter timestamps, quotes, and action items. YS Summarizer below is a different path: paste a public YouTube URL in any browser for Key Takeaways, Connected Ideas, Structured Summary, or Detailed Article when captions already exist—then copy/download Markdown or browser-print PDF. We do not offer a Chrome extension sidebar, clickable timestamp chapters, or a bring-your-own Gemini/OpenAI API key workflow. A common comfort ceiling here is about ~90 minutes—do not treat longer claims as parity. Prefer NoteLM when you want their extension + API-key chapter workflow; prefer this tool for a fast paste-a-link text summary. We are not NoteLM.ai / NoteLM and are not affiliated. This page is about NoteLM.ai—not Google NotebookLM (see our separate NotebookLM comparison page).

NoteLM.ai (extension + Gemini API key) vs paste-a-link web notes

NoteLM.ai publicly positions YouTube summary through a Chrome extension workflow that typically expects you to supply a free Gemini API key, often highlighting chapter timestamps, quotes, and action items. YS Summarizer answers a narrower job: when captions already exist on a public YouTube video, paste the link and get structured text notes—no extension sidebar and no API-key setup.

Not Google NotebookLM — and honest product limits

Do not confuse NoteLM.ai / NoteLM with Google NotebookLM. We keep a separate comparison page for NotebookLM. On this site: no clickable timestamp chapters, no extension sidebar, caption-driven only, and a common ~90-minute comfort ceiling—we do not claim parity with longer-video marketing from extension tools.
