Byline is an opinionated writing flow tool. It is a web rich text editor for writers who want AI help while ACTUALLY being in control. It is a rich-text editor where writers define their writing context and receive suggestions directly at the cursor: hints, phrases, sentences, or questions. Nothing enters the document until the writer accepts it. Users can also paraphrase, find synonyms, adjust tone, and connect two sentences. Byline combines grammar checks from Harper.js, reader feedback, and source-backed findings from its Library, which extracts useful information from links and PDFs. Writing must involve lots of reading, so we want to streamline this back-and-forth into one workflow. Built with TipTap, FastAPI, and React. All inference runs on Meta models. The whole app is built to challenge one assumption: AI should generate everything in one go. We want AI to help line Byline.
