Protected in transit
Connections to UltiWrite services use TLS. Authentication credentials are not stored in plain text.
Security
Your manuscript belongs to you.
UltiWrite limits how services participate in your work and keeps authorship, portability, and explicit choices at the center.
Protected connectionsOptional AIPortable exports
Protection with a clear purpose.
Each control answers a practical question about who can reach the work and where it can go.
Payment boundaries
Full payment-card numbers are handled by Stripe rather than stored on UltiWrite servers.
Explicit AI choices
AI tools remain optional. Hosted requests receive only the material needed for the selected operation.
Local model paths
Bring-your-own provider keys are encrypted at rest. Local model connections can keep processing on your machine.
Portable work
Export the manuscript to EPUB, PDF, or DOCX so the finished work can leave the studio in familiar formats.
