## What makes RangeSharp different?

* **Decision-tree navigation** — Your strategies are organized the way you think about poker: by position, action, and situation. No more digging through folders.
* **Unified workspace** — Edit, view, and compare ranges all in one place. No switching between separate apps.
* **Spaced repetition** — RangeSharp uses the FSRS algorithm (the same science behind language-learning apps) to schedule your reviews at the optimal time.
* **Paste-to-import** — Copy output from PioSolver, HRC, Equilab, or other solvers and paste it directly. RangeSharp detects the format automatically.
* **AI training debrief** — Get analysis of your training sessions that identifies patterns in your mistakes, not just individual errors.
* **Auto-save with undo** — Your work saves automatically. Made a mistake? Undo up to 100 levels.
