What players say about the extension

Absolute best chess plugin, this saves so much work compared with manual position setup.

Jan WeststrateChrome Web Store Chessvision.ai Chess Position Scanner · Review excerpt ·

I rarely write reviews but this has been really helpful for me. Any chess project that needs disecting and scanning diagrams, this is the best. Better than normal LLMs at scanning.
