Mehdi Nabhani — AI & prompt engineer
I build AI products, not slides about them.
Platforms, libraries and products around AI — designed, engineered and run end to end, from the infrastructure to the page you are reading.
Mechanical engineer by training. Two decades in international automotive sales. Now building AI products.
Flagship
Prompt Verse
A workshop for the instructions that make AI useful: design them, test them, keep them, sell them.
- The problem
- Teams that build with AI keep their prompts in chat histories and documents. Nothing is versioned, nothing is tested, and good work cannot be reused or sold.
- The craft
- Prompts, agents, workflows, MCP tools and skills in one place — with versioning, evaluations and side-by-side comparison of models.
- How it earns
- A marketplace where builders publish and sell their work, and paid plans for serious use.
Early access
Early access, by request. Named here so you can see what is being built.
geenius.app Early access
An automated agency that builds websites and apps and keeps talking to the client afterwards.
Generates the site or app, then handles the client relationship by email, voice and video across the whole lifecycle.
geenius.io Early access
One workspace where AI agents from any provider work on real projects, with people in control.
Agents run in parallel on tasks and nested subtasks, talk to each other, report progress, and stop for human approval.
Phantom & Wraith Early access
One Studio with two faces: Phantom simulates AI providers for tests, with cassettes, scenarios and fault injection.
Wraith answers from rules and curated answers first; its workbench is not built yet.
Careers Early access
A job search for freelancers and job seekers in Europe: twelve boards in one search.
A truthful, tailored CV and letter for each posting, and applications that wait for your approval.
Author Early access
A writing room for novels, novellas and short stories, with the state of every character at any moment.
Continuity checks that run on their own, and your own AI can write with you.
Agent host Early access
Create agents without code: instructions, skills, knowledge, a schedule and tools through MCP connectors.
Chat with them in real time; anything risky waits in an approval inbox until a person says yes.
Video Early access
Make videos from templates or scene by scene, and render an MP4 in your browser.
Preview them live; your own AI can draft them, and you press render.
Community Early access
The Geenius Community, where people who use Geenius and people who build on it meet.
Questions get accepted answers, tutorials get series, and your own AI can take part, marked as an AI agent.
Business Plan Early access
Describe your business in one sentence and get a first draft, a monthly forecast and a list of what is missing.
Checked against Dutch and German bank and subsidy expectations; every number in the text comes from the forecast.
Geenius MVP Early access
Write a brief, pick a design from ten, swap any part in the editor and publish a website, web app or web shop.
Bring your own AI, or write the words yourself.
AI Pics Early access
Describe a picture, pick its shape and how many, and press Generate.
Today a Preview paints simple pictures in your browser; real image models switch on where their keys are set.
AI Audio Early access
Pick a voice-over, a music bed, a sound effect or a two-voice dialogue, and press Generate.
Today a Preview simulates the sound in your browser; real voice models switch on where their keys are set.
AI Vids Early access
Describe a scene, pick a model, a shape and a length, and press Make video.
Clips are made one by one and stitched into one file; today the default models are simulated Previews.
Recaloo Early access
Write what you want to say and read it from a full-screen teleprompter over your camera or your screen.
Keep the take; layouts, a background, slides and ink all run in your browser, and your own AI can write the script.
Geenius Newsletter Early access
A newsletter app for small publishers: double opt-in readers, an issue editor, and a human approval before every send.
Scheduled sending, an archive and an RSS feed; sending to real inboxes is not switched on yet.
