GPTyper is a minimalist note taking app that uses LLMs to help you write essays, lecture notes, stories, poetry, project plans, daily journals, and more. This was originally a Node.js web-app, but has been converted to a static site for reduced server costs. Check it out at gptyper.jckpn.com (requires OpenAI API key).

Made with jQuery, this also serves as an example of a static site with language model capabilities. This is usually a bad idea due to API key exposure, but this risk is nullified as the user provides their own API key.
