Co-founder & CTO at Mobile Reality

About

I'm Marcin, Co-founder & CTO of Mobile Reality, based in Warsaw, Poland. We build tools that push what AI can actually do — not just talk, but act. Our latest open-source project is MDMA (Markdown Document with Mounted Applications): a format that lets LLMs respond with interactive forms, approval gates, and structured data instead of plain text. If you think AI conversations should be actionable, not just readable — you'll love what we're building. Always happy to connect with founders, developers, and anyone obsessed with the future of human-AI interaction.

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.
