Home of independent expert newsletters on finance, tech, science and more. Individual post URLs import as Website sources; some posts sit behind paywalls.

A good place to find sustained, opinionated analysis from someone who works in the field a notebook is exploring, especially on topics too new or niche for mainstream coverage. There's no editorial vetting behind these newsletters, so the rigor depends entirely on the individual writer, and some of the best ones sit behind a paid subscription.

## Import into Gemini Notebook

1. Copy the link: https://substack.com
2. In your notebook, click Add source → Website.
3. Paste the link and confirm — several links can be pasted at once, one per line.

**Tip:** Public YouTube videos with captions import as sources directly, with timestamped citations. For podcasts, upload the audio file — Gemini Notebook transcribes it.

## More video & audio sources

- [YouTube](https://gemini-notebook-hub.online/sources/youtube.md) — Lectures, talks and interviews — paste the video URL. For whole channels or playlists, see the tools page.
- [TED](https://gemini-notebook-hub.online/sources/ted.md) — Every talk has a full transcript page — paste that URL for a cleaner import than the video.
- [Podcast episodes](https://gemini-notebook-hub.online/sources/podcast-episodes.md) — Find the episode, download the audio file, upload it as a source — long interviews become quotable, searchable text.
- [Pocket Casts](https://gemini-notebook-hub.online/sources/pocket-casts.md) — Podcast app with strong discovery for expert shows. Use it to find episodes, then feed transcripts or show-notes pages into your notebook.
- [Spotify Podcasts](https://gemini-notebook-hub.online/sources/spotify-podcasts.md) — Massive podcast catalog with expert interviews on nearly any subject. Audio can't be imported directly — look for episode transcripts or show notes instead.
- [Vimeo](https://gemini-notebook-hub.online/sources/vimeo.md) — Indie film, documentaries, and design reels without the ad noise. Gemini Notebook can't ingest Vimeo video directly, so pair clips with transcripts.
