Algernon Sprintv1.0.0

A student has 25 minutes before an exam and wants to review multiple subjects. They run a sprint that shuffles due cards from all installed materials, forcing interleaved retrieval across topics to strengthen long-term retention.

After completing a sprint, the system automatically administers a 5-card post-sprint retrieval test and calculates retention gain compared to FSRS predictions, providing feedback on the effectiveness of interleaved practice.

A user wants a focused 45-minute study block. The sprint automatically limits cards to 60 and includes a 5-minute break, then a test, making it ideal for structured, time-boxed study.

A learner has due cards from biology, history, and math. The sprint interleaves them so no two consecutive cards are from the same material, enhancing context switching and recall.

After each sprint, results are appended to a conversation log in the format '[HH:MM] sprint 25min Cards: 20 | Sprint retention: 70% | Post-sprint: 75% | Gain: +5%', enabling tracking of study progress over time.

Basic sprint functionality (15-minute sprints) is free, while 25- and 45-minute options, detailed analytics, and post-sprint gain metrics are premium. Revenue comes from monthly subscriptions.

Users can buy additional sprint durations or themed sprint packs (e.g., exam prep, language learning). Each pack costs a fixed price, generating incremental revenue.

Schools or tutoring centers license the sprint module for use by students or teachers. Pricing is per-seat or per-school, with volume discounts.
