Play Chess with ChatGPT (OpenAI, GPT 3.5 or GPT 4) or GeminiPro (Google). There are two modes: (A) The standard mode, both you and the AI would follow the standard chess rule, so no illegal move! You can choose between: 1. The native ChatGPT4 API (weakest chess player); 2. Prompt improved GPT4 API (e.g. better chess player); 3. Enhanced backend chess calculation API call with GPT4 (i.e. strongest chess player). (B) The No-Rule chess mode. In this mode, we strictly follow the instruction provided by ChatGPT AI to make the move. Enjoy a chaotic and hilarious chess game. Don't be surprise if AI makes illegal moves, captures its own piece, generates random pieces, and suicides. :) You can choose different LLM AI: 1. GPT 3.5 (OpenAI); 2. GPT 4 (OpenAI); 3. Gemini Pro from Google. A minimalist design, just start to play, that simple. Also, the ChatGPT will talk to you during the play! Come and see if you can beat the ChatGPT in chess!

Verdict
The clearest difference is review sentiment: Chess Jester at 100% against GPT Chess's 33%. GPT Chess's advantage is rating (4.1 vs 3.7) and update cadence (every 9 days vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. GPT Chess sells 1 in-app purchase, starting at $1.99 per month and Chess Jester sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
GPT Chess holds the better App Store score, 4.1 against 3.7. That said, the two scores are not equally well evidenced: GPT Chess has 16 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 33% of GPT Chess's written reviews are positive against 100% of Chess Jester's, so the app with the better star average is not the one people write more warmly about.
GPT Chess ships an update every 9 days, Chess Jester every 3 months. Both last shipped on October 24, 2026.
