Tool Information
DGM is a local-first diagramming and sketchnote application with code-based diagrams, freehand drawing, reusable components and optional AI-assisted visual creation. Users should protect architectural and client information, verify generated structures and labels, preserve source files, test exports, review accessibility and collaboration permissions, and retain accountable design ownership.
Use only authorized, minimal inputs. Configure privacy, retention, permissions, integrations, models, disclosure, export, quality, accessibility, moderation and spending controls. Test the complete workflow with representative cases, verify generated facts, links, calculations, code and media, preserve originals and version history, and retain accountable human approval before publication, customer contact, software release or operational action.
The local application is free forever, with optional paid cloud or collaboration services. Storage, synchronization, teams, AI features, hosting, renewal and future plan limits may vary.
AI output can be inaccurate, biased, derivative, insecure, incomplete or misleading. Review consent, copyright, likeness, commercial rights, training and retention terms, renewals, refunds, platform rules and applicable law. High-impact business, hiring, education, security, financial and customer-service decisions require qualified human review.
