Forget “one-click” proposal builders. The secret to success in Horizon Europe is not automation — it’s smart interaction. With HorizonEurope.ai, you get step-by-step, prompt-based guidance to co-create powerful proposals with any generative AI tool you prefer.
Why Most AI Tools Fail at EU Proposal Writing
Most AI-based proposal tools make one of two mistakes:
They automate without structure, generating vague or off-target sections.
They skip the evaluator’s mindset, failing to meet key Horizon Europe scoring criteria.
AI is a brilliant assistant — but only if you guide it with the right instructions. That’s where prompt engineering comes in.
Your AI Assistant Doesn’t Need to Know Horizon Europe. You Do.

Created by One of Europe’s Top Funding Experts
This tool was built by Nikolaos Floratos, an EC evaluator since 2003 and EU funding coach with over 27 years of experience.
He developed this prompt-based system after realising what every expert knows:
"AI can support the process, but success comes from using the right questions, not the wrong answers."
Stop Using AI Like a Toy. Start Using It Like a Tool.
Sometimes, You Need a Human — Not Just a Prompt.
Even the best prompts can’t replace an experienced expert who’s seen hundreds of winning and losing proposals.
That’s why we offer something no automated tool can match:
🔴 Live 1:1 or team Zoom consulting sessions with a Horizon Europe expert
🕒 From 1 to 3 hours, tailored to your needs
💡 Focus on your idea, your call, and your proposal strategy
✔️ Walk through the Horizon structure step-by-step, while co-developing content using your favourite AI tool
