How to Stop Forgetting What You Read

For people who read to apply knowledge—not just to enjoy it—forgetting is a major bottleneck: studies cited in the transcript say readers lose about 75% of what they read within seven days. That gap matters when the stakes are practical, like learning common mistakes for a new software business, preparing for high-stakes exams such as the MCAT or LSAT, or improving communication to protect a relationship. The core fix offered is spaced repetition, a method designed to resurface information just as it’s about to fade.

Readwise’s Daily Review turns spaced repetition into a daily workflow. It uses an algorithm to bring back notes and highlights from books, articles, podcasts, tweets, and more, and it can import highlights from over 30 platforms. Users can complete reviews in whatever channel fits their routine—email, the web app, or iOS and Android apps. Even without existing highlights, the system can still generate reviews using supplemental highlights or by importing from physical books; there’s also a feature to photograph a page and convert the captured text into a digital highlight.

The transcript emphasizes that the approach isn’t just theoretical. Readwise cites internal surveys running since 2017, reporting that the average user remembers about twice as much after signing up, and that many users feel better able to apply ideas over time—connecting concepts into a personal “big picture,” improving writing by studying others, and even using survival knowledge when circumstances demand it.

Beyond the basic resurfacing, the Daily Review is presented as highly tunable. Users can set delivery timing and frequency (daily, every other day, weekly, or never) and choose a time zone and time of day, including push notifications and an iOS widget that cycles highlights on the home screen. Review length is adjustable: the transcript notes that a default of 15 highlights felt too long for one user, who later found five highlights per review to be a “sweet spot.” The algorithm can also be biased toward newer or older highlights, and a “highlight filter” can remove sentence fragments and overly long highlights that may lose meaning when reviewed out of context.

Users can further control what appears by adjusting document types and tags. Frequency tuning lets people prioritize certain sources (like research papers over books and tweets) or focus on a tagged interest set in Readwise Reader, such as video scripting. During a review, users can also nudge the system to show more or less of a specific document.

Finally, the workflow scales from simple to advanced. Email is positioned as a low-friction option for reconnecting with highlights, while clicking into the web or mobile app adds editing, progressive-style formatting (bolding main points), note expansion, inline tags, and tagging support for Reader. Desktop tools include keyboard navigation, copying highlights, discarding them so they won’t resurface, favoriting, and creating shareable quote images. The system tracks streaks, breaks if a review is missed, and can be recovered within seven days. The overall promise is straightforward: spaced repetition plus customization makes forgetting less likely—and makes reading more usable.
