MDMA - GenUI for apps
Turn AI chat responses into interactive forms and workflows
MDMA is an open-source format that lets LLMs respond with mounted applications — forms, approval gates, interactive tables, and webhook triggers — right inside Markdown. No custom UI needed. Works with any model: OpenAI, Anthropic, Gemini, or local.
Hey Product Hunt! I'm Marcin, Co-founder and CTO at Mobile Reality, and I've been obsessed with one problem: AI chat responses are only text.
LLMs can reason, plan, and write - but the moment they respond, everything collapses into a wall of plain text. Need user input? "Please fill in these fields." Need approval? "Reply YES to confirm." It's like having a genius assistant who can only communicate through sticky notes.
MDMA (Markdown Document with Mounted Applications) changes that. It's an open-source format that lets any LLM respond with real, interactive UI: forms, approval gates, editable tables, charts and webhook triggers. All embedded right in Markdown.
No custom frontend needed. No vendor lock-in. Works with OpenAI, Anthropic, Gemini, or your local model. Your AI response becomes an app.
We've built the parser, the React renderer (but will add more renderers soon), a prompt pack for major LLMs, and an evaluation suite with 60+ tests. It's MIT-licensed and ready to use today.
Would love to hear what use cases come to mind for you! What would you mount in your AI responses?
Finally, interactive components instead of walls of text. MIT licensed and an MCP server included, going to try this on my next agent. Congrats on the launch.
We open-sourced MDMA because plain-text LLM output was the bottleneck in every agent we built. Now the model replies with forms, tables, approval gates and charts instead of paragraphs, parsed deterministically from Markdown plus YAML, with PII protection and an audit log built in. 98% reliability across GPT, Claude, Gemini and Llama, MIT licensed, MCP server and Agent Skill included. Try it and tell us what breaks, we read every issue.
