Relevance, not the algorithm

A feed that's ranked to your goals

Tell Prism what you're learning and it reads each video's transcript to score how useful it actually is — so the best stuff rises to the top and clickbait sinks.

  • Scored against your goals, not view counts
  • See why each result matched
  • Less doom-scroll, more progress

FAQ

Questions, answered

The words we use and how Prism fits into how you learn.

Prism is YouTube for people who watch to learn. It scores every video against what you're trying to learn and plays only the parts worth your time - so a two-hour talk becomes the fifteen minutes that actually move you forward.
Your Lens is your learning profile - the topics you care about, the goals you're working toward, and how you like to learn. Everything Prism ranks and recommends is filtered through it, which is why the feed rebuilds itself the moment you sign up and set one.
Instead of sorting by views or recency, Prism reads each video's transcript and scores how closely it maps to your goals. The most relevant results come first, and each one shows why it matched - so you're not guessing whether something is worth opening.
Prism breaks a video into labeled segments and scores each one for relevance. Green sections are the high-value parts; dim ones are tangents or filler. You can jump straight to any section or let Prism skip the low-relevance ones for you.
Focus Play is an auto-supercut: it strings together just the high-relevance sections - across a single video or an entire project - and plays them back-to-back, skipping everything in between. It's the fastest way to get through a topic.
A project is a collection of videos pointed at one goal (“Learn Django,” “Ship my first AI agent”). Save videos from your feed, from YouTube, or by pasting a link; each one gets its own notes, timestamps, and quiz, and Focus Play can run the whole project as one lesson.
Prism AI reads the transcript so it can summarize a video, answer questions about it, and generate quizzes - with answers cited back to the exact timestamps, so you can verify and jump straight to the source.
Three steps:
  1. Create a free account and build your Lens - pick your topics and goals.
  2. Your feed rebuilds around you. Watch with Sections and Focus Play, save what matters into projects.
  3. Take notes, quiz yourself, and ask Prism AI anything. Your library syncs across devices, and the browser extension lets you save straight from YouTube.
Yes - it's free to start. Create an account, build your Lens, and start learning; you can explore the whole flow before deciding whether you want more.
All the content is YouTube. Prism doesn't host videos - it's a lens on top of YouTube that scores, sections, and organizes them around your goals, so you keep the library you already know with a way to learn from it deliberately.
