You'll spend years of your waking life on this content anyway, so you might as well retain the ideas you take in! Most of them vanish within days. BrainRetain fixes that with spaced repetition, the memory method med students use to hold thousands of facts for years. Whenever you see something you want to remember for the long term, share it with BrainRetain, and our algorithm forces your nervous system into remembering it. What you learn online finally stays. It uses the same method about 68.3% of US med students use to remember thousands of facts: spaced repetition. IT ACTUALLY WORKS: • 317 published experiments confirm spaced repetition beats cramming information for long-term recall (Cepeda et al., Psychological Bulletin 2006). • About 68% of US medical students use spaced repetition (Halperin et al., J Med Educ Curric Dev 2024). • Week-later recall jumps from 36% to 80% when you swap re-reading for being quizzed (Karpicke & Roediger, Science 2008). HOW YOU USE IT: • You see content that you want to remember for the long run. • Share a video, podcast, article, screenshot, or your own notes from any of the supported apps. • BrainRetain pulls out the key ideas in minutes. • Rate how difficult each idea was to remember. • Our algorithm shows you the ideas in a pattern that forces them to become long-term memory. WORKS WITH: • YouTube, TikTok, Spotify, Apple Podcasts, Medium, Substack, news sites, and any text you can paste. PRIVACY: • https://brainretain.app/privacy BrainRetain Pro is an auto-renewable subscription. Your subscription auto-renews unless canceled at least 24 hours before the current period ends.

Verdict
The clearest difference is ads: BrainRetain at none against Doomlearning's shown. BrainRetain also leads on update cadence (every 5 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
