Flompt

Flompt is an open-source visual prompt-engineering tool that decomposes raw prompts into typed, editable blocks (role, objective, constraints, examples, output format, etc.) and recompiles them into Claude-optimized XML so LLMs produce more consistent, reliable, and token-efficient outputs; it runs compilation client-side for privacy and adds AI-focused features like a prompt-quality audit, context memory, version history, and 100+ templates to help you spot gaps and improve prompts. It offers a browser extension that injects structured prompts into ChatGPT/Claude/Gemini, an MCP server for Claude Code and programmatic workflows, and one-click automations (Make.com) — useful for prompt engineers, AI developers, and creators who want repeatable, high-quality LLM behavior without hand-crafting long “wall of text” prompts.
