| Fact | Calliope | Scriptorium |
|---|---|---|
| Integrations | The MCP connector supports Claude, ChatGPT, and Cursor, and Calliope also documents a Writer API. | The Pro collaborator can use a local model, Ollama, or the user's own OpenAI or Anthropic account. |
| Privacy | The privacy policy says Rhymenoceros is a GDPR controller, uses hosting, AI-model, analytics and payment subprocessors, does not sell content or build advertising profiles, and supports deletion requests. | The app works offline with local processing by default; if a user enables OpenAI or Anthropic, only the question and relevant passages are sent, and the API key is encrypted on the user's machine. |
| Purpose | Calliope is a manuscript studio for novelists, with AI for research, canon memory, and consistency checking. | Scriptorium is a writing tool for novelists and series writers that searches a manuscript, canon and notes before answering questions. |
