Description

I built FSRS Simulator Inspector, an Anki add-on that makes the built-in FSRS simulator much easier to understand and control. Instead of only simulating an entire preset, you can choose a single deck, that deck plus its subdecks, or the whole preset. It shows which cards are actually included, how many are new/learning/review, lets you change simulation settings like desired retention, new cards/day, review limits, maximum interval, and review order, and lets you compare multiple simulation runs on the same graph. It also adds an FSRS Simulator option directly to the deck screen so you can launch a simulation for the deck you are currently viewing. The simulation is read-only unless you explicitly choose Save Changes to Preset.
