Stop editing massive system prompts. Break agent and coding prompts into reusable, testable building blocks.

If you're composing complex prompts for agents or code, just a text editor isn't enough.
Designed for agent system prompts, coding task scaffolds, and meta-prompts.
The recommended way to structure an agent prompt.
The embedded ChatNode lets you run your composed prompt, see the rendered output, and iterate quickly—all without leaving the canvas.
ProForge helps you design and validate prompts—you run them wherever you like.
Export your final prompts as plain text, Markdown, or structured formats. Paste into Cursor, OpenAI, Anthropic, automation tools, or your own code.
You own your prompts. ProForge is your design workspace.
Drag images onto the canvas, use them with ImageGenerationNode, and build richer prompts visually.
Limited projects, basic nodes
Unlimited prompts, export, chat testing
Version history, advanced nodes
ProForge is a visual IDE for composing, understanding, and debugging large AI prompts. It's designed for people who build serious AI workflows—agent developers, automation engineers, and prompt power users who have outgrown text editors and copy-paste workflows.
ProForge isn't a chat interface—it's a prompt design tool. You use ProForge to compose, structure, and test your prompts visually, then export them to run in ChatGPT, Claude, Cursor, or any AI tool you prefer. Think of it as an IDE for prompts, not a replacement for the AI itself.
TextNodes hold pieces of your prompt—instructions, examples, rules. TemplateNodes let you combine them using moustache variables like {{role}} and {{task}}, making it clear how each part contributes to the final prompt. You drag and connect them on a visual canvas.
Yes. ChatNodes let you run your composed prompt directly and see the output without leaving the canvas. This is for design iteration and validation—once you're happy with a prompt, you export it and run it wherever you need.
ProForge has built-in support for ChatGPT, Claude, and image generators. But the prompts you build are plain text—you can export and use them with any AI model, including Cursor, Gemini, open-source models, or your own fine-tuned models.
ProForge is not for casual ChatGPT users, beginners learning about AI, or one-off simple prompts. It's built for people who write prompts over 500 tokens, build AI agents, or need to maintain and debug complex prompt systems.
You can copy the rendered prompt text with one click, or export as plain text or Markdown. The prompt is yours—paste it into Cursor, your automation tools, or your own code.
Your prompts stay in your control. We don't send your prompt content to third parties unless you explicitly run it through a built-in AI service. You decide where your prompts go.
