ERD generator for fast understanding

Turn schema metadata into clear diagrams that people can read and trust. Move from overview to detail in one click and keep diagrams in sync as the schema evolves.

ERD is coming soon. You can start documentation today and add diagrams when ready.

Why teams want ERD inside the same tool

Shared mental model

A diagram is a fast way to align engineers, analysts, and stakeholders on how entities relate and where truth lives.

Fewer mistakes

See keys and cardinalities at a glance. Reduce wrong joins and missing constraints in sensitive areas.

Faster onboarding

New people learn through a visual map with links to table detail and documentation notes.

How ERD in Data Pilot will work

1 Scan the schema to detect tables, keys, and foreign key relations. Group by schema and filter by tags or naming patterns.
2 Lay out the diagram with an automatic engine. Drag to refine. Save your preferred layout per workspace.
3 Click to detail to open the table view with fields, keys, and documentation notes. Update texts and native comments from there.
4 Export clean images for slides and wikis. Choose PNG or SVG and optional labels that fit your audience.

PostgreSQL is available today. MySQL and SQL Server are next. Oracle is planned.

Planned capabilities for ERD

Focus and search

Search by table name or column. Hide noise with schema and tag filters. Highlight the path between two tables.

Annotations

Add notes for tricky domains. Keep purpose and usage near the entities without leaving the diagram.

Diff and version history

Compare diagrams across releases and understand what changed and why. Share a link to a named version.

Non destructive edits

Propose relation notes and naming suggestions without altering the live database. Keep engineers in control.

Timelines may evolve as we gather feedback. We will announce milestones in the changelog.

Benefits you can measure

Clarity for reviews

Code reviews move faster when reviewers see relations in context and can jump to detail on demand.

Better handovers

A shared map reduces back and forth during ownership changes and helps new contributors avoid guesswork.

Docs that people read

ERD and text live together so documentation stays useful and up to date.

How this compares

Many visual design suites are tailored for large enterprise programs and can require higher spend and long onboarding. Data Pilot aims to be simple to adopt with a focus on schema introspection and living docs. Start with documentation today then add ERD when the feature is released.

If you want a detailed comparison page we can publish a table with public plan details from well known tools and keep it current over time.

Security and data handling

Use a read only role and scope access to the needed schemas.
ERD uses metadata such as tables, columns, keys, and relations. Data rows stay in your database.
Secrets are stored with encryption at rest where applicable. Connections use encryption in transit.
You control exports and who can access them inside your workspace.

AI diagram generator with real schema context

Many people search for a diagram generator ai or a diagram ai generator. Data Pilot starts from your live database so relations are accurate. You can move from a clear diagram to table detail, review notes, and export clean images.

Scan keys and foreign keys from your schema
Lay out entities with readable labels that match your naming
Click to detail for columns, constraints, and comments
Export PNG or SVG for slides and wikis, open in diagrams dot net for freeform edits

Mermaid ERD for lightweight docs

Mermaid ERD is popular for quick diagrams in repos and wikis. Data Pilot focuses on diagrams from live metadata. When you need a text based diagram you can export an image and place it next to your Mermaid notes, or embed a small Mermaid snippet for tiny models.

erDiagram
  USERS ||--o{ ORDERS : places
  ORDERS }o--o{ ORDER_ITEMS : contains
  PRODUCTS ||--o{ ORDER_ITEMS : appears

Use Mermaid for tiny examples and keep live diagrams for full schemas.

Prisma ERD generator and live databases

Developers often look for a Prisma ERD generator. Prisma schemas are great for application models. Data Pilot reads the actual database so diagrams match the deployed relations. This helps during reviews and handovers across teams.

Use Prisma for your app model and migrations
Use Data Pilot to scan the live database and share diagrams with non developers
Keep explanations in native comments so diagrams and text stay aligned

A short guide on Prisma and ERD will be available in our blog.

More about ERD and diagrams

Is there an online ERD generator

Yes. Data Pilot will offer a simple online flow when ERD is released. You can create documentation today and join the waitlist.

Can I use diagrams dot net with your exports

Yes. Export PNG or SVG and import it into diagrams dot net for freeform edits.

How is this different from a general chat tool

A chat tool does not know your schema. Data Pilot reads tables, keys, and relations so the diagram reflects reality and links to detail.

FAQs

Which databases will the ERD support

PostgreSQL is available today for documentation. ERD will start with PostgreSQL and then add MySQL and SQL Server. Oracle is planned.

Will ERD change my schema

The first release focuses on read only diagrams. Later milestones may add non destructive proposals that engineers can review.

Can I export diagrams

Yes. The plan is to export PNG and SVG with options for labels and density so diagrams fit slides and wikis.

How does ERD relate to documentation

ERD gives the visual map. Each entity links to table detail where you keep descriptions, notes, and native comments in sync.
