Learn from any YouTube video — and actually remember it. Most of what you watch fades within days. Fathomly makes it stick. Paste a link on any topic and Fathomly turns it into an interactive learning path that breaks down core concepts, tests you with active recall, and brings ideas back just before you forget them. As you improve, questions adapt to your level so you are always challenged at the right depth — whether it is philosophy, business, history, or science. Backed by cognitive science: active recall and spaced repetition are the two most reliably proven methods for long-term retention. Everything you need to master a topic: • AI Video Summaries: Get the core takeaways and structure before you dive in. • Takeaway Gallery: Save key mental models and distilled ideas from each lesson into your personal collection. • Topic Debate: Argue the topic out with an opponent that pushes back, so you truly understand both sides. • Retention Curve: See exactly what you remember and what needs shoring up over time. • Go Deeper: Branch off into deeper subtopics once the basics are locked in. Free to start. Upgrade to Fathomly Scholar (£2.99/week, £8.99/month, or £79/year) to unlock unlimited paths, debates, and summaries. Learn what you want. Remember what you learn.

Verdict

The call

The clearest difference is rating: Peak at 4.7 against Fathomly's 4.0. Peak also leads on ratings volume (146K vs 2) and chart position (#178 vs unranked). Fathomly's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Peak sells 10 in-app purchases, starting at $2.99 per month and Fathomly sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings
