ChatGPT-web is a simple one-page web interface to the OpenAI ChatGPT API. To use it, you need to register for an OpenAI API key first. All messages are stored in your browser's local storage, so everything is private. You can also close the browser tab and come back later to continue the conversation.
Why not use the official ChatGPT interface? Becauce ChatGPT-web will allow more customization, and since it uses the commercial OpenAI API it should be more reliable. It's also much cheaper than ChatGPT Plus - at $20 per month, you would need to use 10 million tokens on the OpenAI API for this to break even. Finally, since ChatGPT-web is open source, so you can host it yourself and make changes as you want.
