Selection & sources
These are editorial selections for discovering useful channels, not a ranking by subscribers, popularity or revenue. Entries are alphabetical. We include independent creators, creator-led teams and a small number of educational organisations. AI covers tools, research, creative work, coding and the foundations needed to understand it. Tech includes software, hardware, electronics, repair and engineering.
Channel identities, descriptions and recent upload titles were checked against public YouTube pages on 9 November 2026. The blurbs are our own editorial summaries; inclusion does not mean we have watched every video or endorse every claim. Some channels have valuable archives even when they publish less frequently.
Project links come from official channel pages or the project's own website. The relationship label distinguishes personal sites, courses, communities and businesses. A linked product is not automatically owned by the creator; corporate ownership has not been audited. We omit sponsor and affiliate recommendations from the project field unless a separate creator relationship is established. “No separate project confirmed” means our reviewed sources did not establish one, rather than that none exists.
Creators may appear in both collections. Related channels from the same creator are not counted twice within a list. Luke Byrne publishes this directory and is included with that relationship disclosed. No one paid for inclusion. For corrections, use the contact details on our About page.
