Anki add-on: Anki Time Warp

Anki Time Warp is a review timeline manipulation tool designed for serious Anki users who need greater control over their study schedules. This add-on enables simulation and rewriting of card due dates with full preview capabilities. It was created to help learners: Tackle intensive exam preparation periods by prioritizing specific thematic areas. Avoid review backlogs caused by holidays, breaks, or burnout. Strategically adjust future review loads without manual rescheduling. By visualizing and reshaping your review timeline, Anki Time Warp empowers you to take control of your spaced repetition workflow without compromising long-term retention. -- Key Features Time Stretching Stretch future review intervals by a defined percentage. Helps spread reviews more evenly over time. Time Shifting Shift all scheduled reviews forward or backward by a specific number of days. Ideal for catching up after a break or preparing ahead. Simulation Mode Preview transformed review schedules over a 90-day horizon before committing any changes. Deck & Tag Filtering Select specific decks or filter by tags to isolate exactly the cards you want to manipulate. Filtered Deck Creation Create a filtered deck with the transformed timeline. Review cards in new order without affecting original scheduling unless drawn. Permanent Change Option Apply changes directly to card due dates for long-term impact. Visual Timeline Chart Interactive timeline visualizes the effect of stretching/shifting so you can fine-tune parameters before committing. Motivation Anki’s built-in scheduler excels at optimizing long-term memory retention, but it lacks tools for flexible timeline planning. Whether you're preparing for medical boards, semester finals, or language proficiency exams, there are times when you need to bend the schedule to your needs. This add-on was created to: Facilitate short-term prioritization of important material. Avoid review accumulation after downtime. Provide a visual overview of the review load. Experiment with different scheduling strategies without risk. Source Code The full source code and development repository can be found on GitHub .
