How it works

Three steps from idea to AI-ready spec.

1

Organize

Create feature cards with titles, user stories, and acceptance criteria. Drag them across Backlog, In Scope, and Out of Scope lanes.

2

Compile

Select your cards and stack preset, then hit compile. We generate a structured PRD and an AI coding prompt — structured and ready.

3

Ship

Paste the output into Claude, ChatGPT, Cursor, or any AI tool. Get code that matches your stack constraints from the start.

Features

Everything you need to go from brainstorm to build.

Drag-and-Drop Kanban

Organize feature cards across lanes with spatial drag-and-drop. Think visually about scope, priority, and project structure.

Stack-Aware Output

Choose your tech stack preset and get prompts with built-in constraints — Next.js, Rails, Flutter, and more.

Gap Analysis

Spot missing features before you build. Our analyzer scans your cards and flags what’s missing — like auth without password reset, or an API without error handling.

One-Click Compile

Select your cards, hit compile, and get two outputs: a structured PRD for stakeholders and an AI coding prompt with your stack constraints baked in.

Built for builders

Whether you ship alone or with a team, MAGNETprompt fits your workflow.

Independent Devs

Solo developers shipping fast. Turn your feature brainstorm into structured prompts for Claude, Cursor, or ChatGPT in minutes.

Startup Teams

Small teams aligning on scope. Drag cards between Backlog, In Scope, and Out of Scope — then compile what matters.

Agencies

Client projects with clear deliverables. Generate PRDs and prompts per board, per client, with stack-aware constraints.

What builders are saying

Early adopters
“I used to spend 30 minutes writing and researching prompts for each major feature, always worrying about best practices. Now I drag cards into scope and compile — the whole spec is done in seconds. Game changer for solo builders.”

— François REEVES, author of MAGNETprompt

Frequently asked questions

What is MAGNETprompt?
MAGNETprompt is a visual project planning tool that lets you organize features on a magnetic kanban board, then compile them into structured PRDs and AI-ready coding prompts — with stack-aware constraints and built-in gap analysis.
Is it free?
Yes. MAGNETprompt is free to use during the beta. Sign up and start building — no credit card required.
What is gap analysis?
Gap analysis scans the cards on your board and compares them against common software patterns. It flags missing pieces — like a signup feature without password reset, or a payment flow without error handling — so you catch blind spots before you start building.
Which tech stacks are supported?
We ship with presets for popular stacks including Next.js, React + Express, Rails, Django, Flutter, and more. Each preset injects relevant constraints (package versions, architectural patterns) into your compiled output.
Does it work with my AI tool?
Yes. MAGNETprompt generates plain markdown and text prompts. Copy and paste into Claude, ChatGPT, Cursor, Windsurf, Copilot, or any AI coding assistant.
