 ## Benchmarks
 
-> [!TIP]
-> Try the interactive [Format Tokenization Playground](https://www.curiouslychase.com/playground/format-tokenization-exploration) to compare token usage across CSV, JSON, YAML, and TOON with your own data.

 Benchmarks are organized into two tracks to ensure fair comparisons:
 
 - **Mixed-Structure Track**: Datasets with nested or semi-uniform structures (TOON vs JSON, YAML, XML). CSV excluded as it cannot properly represent these structures.

+## Playgrounds
+
+Experiment with TOON format interactively before installing:
+
+- **[Format Tokenization Playground](https://www.curiouslychase.com/playground/format-tokenization-exploration)** – Compare token usage across CSV, JSON (pretty/compressed), YAML, and TOON formats. Use preset datasets or paste your own data to see real-time token comparisons.
+- **[TOON Tools](https://toontools.vercel.app/)** – Full toolkit including bidirectional converters (JSON, CSV, XML, YAML ↔ TOON), token counter with side-by-side comparison, TOON validator, batch file converter, and format playground.
+
 ## Installation & Quick Start
