About twitterbio
twitterbio is an open-source web application that generates Twitter (X) bios using artificial intelligence. It leverages the Together AI API with two models: Qwen 3.5 9B for fast, direct responses (with thinking disabled) and GPT OSS 20B as a reasoning model that displays a 'Thinking...' indicator before responding. Users fill out a form with their details, and the app streams the generated bio back in real time. Built with Next.js and written primarily in TypeScript, the project is MIT licensed and can be deployed locally or one-click deployed to Vercel.
