flompt — Visual Prompt Builder — Nyrok

Build structured AI prompts visually and inject them into ChatGPT, Claude or Gemini.

Stop guessing. Start building prompts that actually work.

flompt is a visual prompt engineering tool that runs directly inside ChatGPT, Claude, and Gemini. Instead of rewriting the same prompt ten times hoping something clicks, you break it down into blocks — role, context, objective, constraints, examples — drag them into the right order, and compile a structured, XML-formatted prompt that AI models actually understand.

Think Figma, but for prompts.

What it does:
Paste any raw prompt into flompt. The AI decomposer splits it into semantic building blocks, each one mapped to a specific function. You rearrange them visually in a flowchart editor, tweak the content, then hit compile. Out comes a clean, Anthropic-optimized prompt ready to inject into your current chat — no copy-paste, no tab switching.

Built for people who write prompts seriously.
Whether you're an AI engineer refining system prompts, a content creator building complex writing templates, or a developer debugging LLM behavior — flompt gives you structural clarity that plain text never will. The 11 block types cover everything from chain-of-thought reasoning to few-shot examples and output format control.

Works where you already work.
The extension sidebar opens on chatgpt.com, claude.ai, and gemini.google.com. One click sends your compiled prompt directly into the chat input. No account required. Free.

Key features:
- Visual flowchart editor powered by React Flow
- AI-powered prompt decomposition (Claude & GPT supported)
- 11 specialized block types following Anthropic's prompt engineering best practices

Better prompts. Less trial and error. That's the whole idea.
