Free is a great place to begin exploring Theus. It gives writers access to the core workspace, allowing them to organize projects, write inside the editor, and use essential non-AI tools in a dedicated creative environment. Free users can keep up to three active projects, view archived work, and use limited daily exports, making it ideal for getting a feel for the platform before unlocking deeper creative assistance.

Basic is designed for writers who want Theus to become an active part of their process. In addition to the full workspace experience, Basic unlocks Theus discussion, chapter generation, rewrites, chapter memory, continuity-aware support, and the broader suite of AI-powered writing tools. It is built for users who want meaningful creative assistance while maintaining a practical monthly plan that supports regular drafting, development, and refinement.

Premium is the full Theus experience for writers who want maximum creative support and room to work at a higher level. It includes everything in Basic, but with expanded generation capacity, more headroom for intensive use, and the strongest overall access to Theus-powered features. Premium is intended for users building larger projects, generating longer chapters, leaning heavily on memory and refinement tools, and using Theus as a true long-form creative partner.
