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.
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.
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.
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.
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.
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.
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.
