I built this for fun. Free to play with your own API key.
Your API key and chat messages are stored locally on your browser. Requests are also sent directly from your browser to OpenAI's server. No data collection.
The original prompt is shown in the first message after you start the game.
Thank you for the suggestion! I'll add an option to select the model soon.
As per your question, currently all the previous messages of the same chat will be included in the request. If you hit the 4k token limit, there will be an error message. I'll look into improving this too.
The landing page is still a work in progress, but the product is fully operational.
Happy to answer any question!
