How does AI determine the right spacing interval?

AI agents use algorithms based on the Ebbinghaus forgetting curve, adjusted for individual performance. If an employee consistently recalls a concept correctly, intervals lengthen. If they struggle, intervals shorten and the agent provides additional practice. The system optimizes for long-term retention with minimal review time.

Spaced Repetition

A learning technique where information is reviewed at increasing intervals over time to optimize long-term retention. AI tutoring and training agents use spaced repetition algorithms to resurface concepts just before they would be forgotten—typically at 1 day, 3 days, 1 week, 2 weeks, and 1 month intervals. This approach is 2-3x more effective than massed practice (cramming) for long-term knowledge retention.

Example

An AI compliance training agent teaches a data privacy concept on Monday, quizzes the employee on it Wednesday, again the following Monday, then two weeks later. Each successful recall extends the interval; a failed recall shortens it and triggers a refresher module.
