Prompt
Describe what you want in one plain-language prompt — the goal, the inputs, the output you care about.

Turn one prompt into a validated multi-agent AI workflow.
AI Workflow Builder takes a plain-language prompt, interrogates you only about the genuinely ambiguous parts (the Grill-Me loop), and produces a versioned spec, a dependency-checked workflow DAG, and runnable Python orchestration code.
How it works
Three stages, one goal: a workflow that runs the first time.
Grill-Me spec loop
Instead of guessing, the builder asks only about what is genuinely ambiguous and resolves it into a versioned spec — before any code exists.
Validated workflow
A workflow DAG is scaffolded, checked for cycles and dangling dependencies, and compiled into runnable Python orchestration code.
What's inside
A complete studio for designing production multi-agent systems.
Deterministic Grill engine
Asks only the questions that matter, scored by ambiguity — no infinite questionnaires.
Workflow DAG designer
Visual node graph with dependency checks — no cycles, no dangling references.
Pre-flight validator
Checks the workflow before it runs, so failures surface at design time, not runtime.
Python code generation
Compiles the validated DAG into runnable Python orchestration code.

100% self-hosted
Download, npm install, npm run dev — done. No accounts, no SaaS, no lock-in.
Self-host in minutes
The entire product runs on your machine. Node.js 22.5+ is the only requirement.
- Download the code from Gumroad (or clone the repo) and unzip.
- Install — installs the API and the web studio together.
- Run — starts the API on
:4000and the studio on:5173. - Open
http://localhost:5173and start building. No sign-up required.
# 1. unzip the download (or git clone …)
$ cd ai-workflow-builder
# 2. install both workspaces (server + web)
$ npm install
# 3. run API (:4000) + studio (:5173) together
$ npm run dev
# 4. open the studio
$ open http://localhost:5173Need the full walkthrough? See the usage guide in the repo.
