About Protocol
We believe that the hours you spend listening to podcasts should translate into real, lasting knowledge -- not information that fades within a week.
Our Mission
Research shows that people forget up to 90% of what they hear within a week. That means the insightful interview you listened to on Monday is mostly gone by Friday. The breakthrough idea from your favorite show? Barely a memory by the next episode.
Protocol exists to change that. We combine proven learning science -- active recall, spaced repetition, and reflective practice -- into a simple workflow that turns passive listening into active learning.
Our goal is straightforward: make every podcast episode you invest time in actually stick.
What Protocol Does
Reflect
After listening to an episode, Protocol prompts you with reflection questions that help you process and articulate what you learned. This is where passive hearing becomes active understanding.
Quiz
AI-generated quizzes test your knowledge on each episode. Retrieving information from memory -- rather than simply recognizing it -- is the most effective way to build durable, long-term retention.
The Team
Protocol is built by a small team passionate about learning, cognitive science, and great design. We are podcast listeners ourselves who got tired of forgetting everything we heard. So we built the tool we wished existed.
