Frequently Asked Questions
What types of data diagrams can I create?▼
Datadef specializes in data architecture: pipelines, warehouses, lakehouses, ETL/ELT flows, data lineage maps, KPI dashboards, and system architectures. Every diagram uses data-specific components like tables, pipelines, data sources, and KPI indicators.
How does the AI generation work?▼
Describe your data stack in plain English: “E-commerce data platform with Fivetran, Snowflake, dbt, and Looker.” Our AI generates a complete diagram with properly connected components, data lineage, and wiki documentation — all in under 2 minutes.
Can I edit AI-generated diagrams?▼
Yes! All AI-generated diagrams are fully editable. Drag nodes, add components, modify connections, change colors, add metadata. The AI gives you a head start — you have full control to refine everything.
How does lineage tracking work?▼
Datadef automatically generates lineage from your diagram connections. Click any KPI or table to see its upstream sources and downstream consumers. Define formulas, track transformations, and do impact analysis before making changes.
What export formats are supported?▼
Export as PNG, JPEG, or PDF for presentations. Export JSON for version control and data portability. Share public links with stakeholders who don't need to log in.
Is my data secure?▼
Datadef never connects to your actual databases. You describe your architecture — we never access your data sources or store sensitive information. All data is encrypted in transit and at rest.
Stop wasting time on diagrams
Whether you're a freelancer delivering client work or a team lead managing complexity — let AI generate the diagrams while you focus on what matters.
