It would be great if there was an option to use it for free, at least test it on a few games. Maybe by running a small AI on the user device.

Hi, this is super cool! My friend and I built a super simple codebase over the past few weeks, that does a similar thing as your idea, which is almost ready for production. I just stumbled on your project a few minutes ago. Your project is more developed than ours. The main difference is that our project is for interactive play between human and computer. We use Stockfish with skill levels to match the human player's level, and then we feed the Stockfish analysis of every human move to the LLM, which will produce coaching guidance based on the Stockfish analysis.

Here's a link to the backend of our project:

@torn swift @peak minnow you can connect to chessagine using your local LLM from ollama such as gpt-OSS models and other big or small models

#

It’s free to use chessagine thanks to Yager for this idea to start with

I added chessAgine cloud models

In my ChessAgine app, I added Q/A mode where ChessAgine asks you chess questions so you have to think and answer it back rather than getting an easy answer. This makes #chess analysis via #LLMs fun, you can be wrong and agine would know it!!

nmp (@nmp123.bsky.social)

my ChessAgine app now has built-in LLM models, I call it ChessAgine Cloud, where people can plug into it without any setup. Here I'm analyzing #chess game between Gukesh vs Arjun using gpt-oss:20b model.

if anyone wants to try it feel free to here, its under active development www.chessagine.com
