About SuperDoc

SuperDoc is an open source document editor bringing modern DOCX editing and advanced collaboration to the web.

We care a lot about building simple, beautiful document experiences that teams can self-host, extend, and trust. Our editor powers real-time collaboration, dynamic LLM-driven suggestions and actions, streamlined agentic workflows, and more. SuperDoc is already the editor platform of choice for a new wave of LegalTech and GovTech companies.

Under the hood, we dynamically bind MS Word OOXML to a ProseMirror schema in our editor JS library, and make it easy for customers to add their own features and AI actions on top. Any prior experience building/extending editors (ProseMirror, TipTap, Lexical, etc.) or parsing OOXML is a big bonus.

We’re a small engineering team that ships fast and works closely with our user community. SuperDoc is an Equal Opportunity Employer.
