The 3-Step Execution Pipeline
How Visual Whiteboard transforms pixels and words into code.
Draw or Describe
Take a picture of your whiteboard layout, capture an ERD screenshot, or describe it in plain English. Paste or upload it directly.
Gemini Structured Analysis
Our secure backend calls Gemini 3.1 Pro under strict JSON schema guidelines, interpreting names, keys, datatypes, and connections.
Get Four Rich Outputs
Review tables/columns, copy clean Prisma models, execute ordered Postgres SQL statements, or interact with a live-rendered Mermaid diagram.
Engineered for Rapid DB Architecting
Everything you need to skip the boilerplate coding of schema creation.
Sketch Image Upload
Drag-and-drop PNG, JPG, WEBP, or GIF sketches of your tables. Files downscaled client-side for rapid generation.
Instant Clipboard Paste
Take a quick crop of a diagram drawing, paste using Ctrl+V anywhere, and generate schemas on the spot.
Natural Language "Describe"
Describe your application needs in plain English and let Gemini structure relationships, primary keys, and junction tables automatically.
Prisma ORM Generator
Generates valid `schema.prisma` files with standard postgres config settings and correctly typed model mappings ready for usage.
Supabase-Ready Postgres
Emits clean CREATE TABLE and ALTER TABLE queries structured in dependency order so database migrations execute without FK errors.
Stateless & Privacy-First
No databases storing your proprietary models or private keys. All configurations are stored locally on your device.
Frequently Asked Questions
Got questions about database generation? We have answers.
How does the image recognition work?
When you drag and drop or paste a whiteboard sketch, our frontend downscales the image client-side to ensure lightweight transmission and sends it secure-proxy style via server actions to Gemini.
What Postgres conventions are followed?
Gemini is constrained to use snake_case plural table names, uuid primary keys with random default values, explicit foreign keys, and safe PostgreSQL types (like jsonb, numeric, text).
Is my data secure?
Yes. Visual Whiteboard is entirely stateless. We do not persist your schemas or files. If you input a custom API key, it is kept 100% locally in your browser's private localStorage.
Are the schemas ready for production?
Yes. The generated Prisma and PostgreSQL SQL are structured logically. However, we advise adding custom row-level security (RLS) policies or specific column validation checks where needed.
