Remember What You Listen To
Most people forget the majority of a podcast within days. Protocol turns listening into lasting knowledge through reflection and science-backed quizzing.


How It Works
Three simple steps to go from passive listener to active learner.
Listen to a podcast
Pick an episode from your favorite show. Protocol supports thousands of podcasts across every genre.
Reflect on what stuck
After listening, answer a few short prompts that help you process and articulate what you learned.
Quiz yourself to lock it in
Take an AI-generated quiz tailored to the episode. Active recall cements knowledge into long-term memory.
Built on Science
Protocol is grounded in decades of cognitive science research on how humans actually learn and retain information.
Active Recall
Testing yourself on material is dramatically more effective than re-reading or passive review.
Spaced Repetition
Reviewing at strategically timed intervals strengthens memory traces before they fade.
Reflective Learning
Writing about what you learned forces deeper processing and personal connection to the material.
