AI API tools and services

ChatGPT-web is a simple one-page web interface for the OpenAI ChatGPT API. You need to register an OpenAI API key before using it. OpenAI is billed per token (based on usage), which means it is much cheaper than ChatGPT Plus unless you use more than 10 million tokens per month. All messages are stored in the browser's local storage, so everything is private. You can also close the browser tab and come back to the conversation later. As an alternative to OpenAI, you can also use Petals swarm as a free API option for open chat models like Llama 2.
