Mynt is an AI writing interface that lets users generate content using large language models. It supports uploading reference data from files, websites, and code, and provides an AI chat feature to discuss and comprehend that data. Users can write and edit documents based on their inputs, then share the output to Word, Docs, PDF, and other formats. The platform emphasizes security by not storing user IP addresses and not using data to train models. It offers a free tier with basic models and the option to connect an Open Router account, as well as paid Pro and Enterprise plans with additional features like collaborative spaces, data encryption, and custom integrations.
