Announcing a community runtime release - free to use, academic and otherwise:

- **ErgoAI Studio 2 with ErgoAI engine, running entirely on your browser**

At [https://ergoai-studio2-wasm.interprolog.com/](https://ergoai-studio2-wasm.interprolog.com/)

Some limitations apply, see menu Help/About ErgoAI Studio 2. Full (searchable) ErgoAI documentation onboard, as well as an IDE tutorial, please see the Help menu.

This is the result of two ongoing projects, to be reported in more detail and open sourced later this Summer:

- **ErgoAI Studio 2,** supporting both the standard XSB based ErgoAI engine, and ErgoAIp.

- **ErgoAIp** , meaning ErgoAI on SWI-PROLOG with a new PROLOG-parseable syntax (plus the ErgoAI standard syntax); the Ergo test suite runs circa 2x faster than on XSB; on WebAssembly, about 5% slower than native SWI; 95% of tests passing at this point; your mileage may vary depending on specific needs .

Please enjoy, and let me know of any problems, questions or suggestions.

Cheers,

Miguel
