What you give up either way
- Proprietary in-house fiction model (Muse) and any model-level optimizations they advertise
- Prebuilt plugin ecosystem and third-party integrations
- Polished UX, themes, and long-term reliability/scale of a mature SaaS
- Advanced features like Feedback scoring, undoable multi-step rewrites, and art/visualize generation
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Sudowrite, and it does not prove anyone has run it for a month. How we decide.
