Turns plain English, Terraform or a SQL schema into an editable draw.io diagram in about 20 seconds
Draft1 turns a written description, or a pasted Terraform file, docker-compose or SQL schema, into a diagram in roughly twenty seconds, and hands back something editable in draw.io rather than a flat image. It covers ER, UML, Kubernetes, network, cloud architecture, flowchart and database diagrams, and can generate accompanying documentation exportable as PDF, DOCX or Markdown. There is a documented REST API with key authentication that creates, lists, retrieves and iterates on diagrams in plain English, so it can run inside a build or a docs pipeline. Draft1 is registered at an address in Paris and operates under French law. Quotas are counted in prompts rather than finished diagrams.
Basic is $24/month for 1,000 prompts, Pro $32/month for 2,000 prompts, Enterprise $99 per user per month adding collaboration and GitHub version control. Creating an account gives three free diagrams with no card required. The metering unit is prompts, so iterating on a diagram that comes out wrong draws down the same allowance as generating a new one.
Use tool ↗The useful decision here is the output format: a draw.io file you can keep editing, not a PNG you have to regenerate every time something changes. Accepting Terraform, docker-compose and SQL as input means the diagram can be derived from the actual infrastructure rather than someone's memory of it. The documented API with a PATCH endpoint for iterating in plain English makes it viable as a docs-pipeline step rather than a one-off toy.
Watch out: Prompt-based metering means a diagram that needs five refinements costs five prompts; the 1,000-prompt tier is not 1,000 diagrams.
