Story Theorem is powered by Claude, Anthropic's advanced AI assistant. We've chosen Claude not only for its nuanced understanding of writing and craft, but for its strong commitment to user privacy.
Your manuscript is your intellectual property. Period. We use Claude's API to analyze your work and provide feedback, but your content is never used to train AI models.

Delta, your privacy-centric AI servant.
We understand authors' concerns about AI and creative work. Here's exactly how we protect your writing.
Story Theorem uses Claude's commercial API, which treats your manuscript as protected business data. API content is never used to train AI models—a core policy distinction from consumer AI products.
API logs are retained for only 7 days for technical support purposes, then permanently deleted. Your manuscript content is not stored long-term by Anthropic.
You retain full intellectual property rights to your manuscript. We never claim ownership of your creative work, and it is never shared with third parties.
This isn't like pasting your manuscript into a standard AI chatbot. We use commercial API, which means your manuscript gets the same security standards as sensitive corporate data.
We believe in transparency. Here are Anthropic's official resources about how Claude handles data:
