What languages does Sudowrite work in?

It supports almost any language; the AI matches your language for suggestions when using Write, but may fall back on English for other features.

Can Sudowrite plagiarize?

No, unless forced. It generates original text by guessing one word at a time based on learned concepts, making verbatim copying extremely unlikely.

What public language models does Sudowrite use?

It uses Claude by Anthropic, OpenAI models, open-source models, and in-house Muse models, with proprietary processing for unique features.

Do you claim any rights over my writing?

No, Sudowrite claims no rights over user input or AI-generated content; you retain full ownership.

No, it's a creativity tool to assist and speed up writing, similar to a writing partner, not a replacement for your work.

If I cancel, do I lose access to what I've written?

You can always access and edit your projects, but AI features require a paid plan; content is never held hostage.
