I built this because I wanted a Google Docs-style editor with GPT-3 tie-in. There are some of these in the wild, but they are expensive.
Why is it useful?
1) It's 50x cheaper to run than commercial solutions that mostly just wrap GPT-3 (you bring your own OpenAI API key)
2) It means you don't have to share your writing with someone in the middle.
