Before they visit a show flat, buyers ask AI which developers build reliably, stick to the Fertigstellung date and handle the Abnahme fairly. MentionX shows what ChatGPT and Gemini say about you, whether it's true, and where you rank on Google.
Shortlists start with AI. "Best Bauträger for Neubau flats in Munich", "reliable developers in Hamburg". If AI doesn't name you, the buyer contacts someone else.
Completion and Abnahme. Buyers ask whether you finish on schedule, how defects are handled at Abnahme, and how payments follow the MaBV instalment plan. Wrong or vague AI answers create doubt.
Old delay stories. A past delayed Fertigstellung turns into "has had delays" in AI answers.
Wrong facts. Old €/m² prices, sold-out projects, wrong energy standard (e.g. KfW Effizienzhaus) or the wrong location.
MentionX compares what AI says with your own website. It does not check registries, authorities or the MaBV status of a project.
Right now, home buyers are asking AI about developers like you. You can't see whether you're named, what it says about your projects, or whether it's true. MentionX shows you, answer by answer.
Example only. Company names are placeholders.
A buyer asks: "Which Bauträger in Frankfurt finish on time?" AI names Company B and Company C and repeats an old delay report about Company A. Google: #3. MentionX shows the claim, its source, and a draft "completed projects and handover dates" page.
Seven steps, from seeing the problem to proving the fix worked.
Not just ChatGPT. MentionX asks ChatGPT, Gemini, Google AI Mode, Google AI Overviews, Perplexity, Microsoft Copilot and DeepSeek the questions home buyers really ask, such as "which developers hand over on time?", and saves every answer word for word. (The number of AI tools depends on your plan.)
Tools available depend on your plan
Fact Check puts what AI says next to the facts on your own website, such as an old price, a sold-out project shown as available, the wrong location or the wrong handover date. You see the wrong claim, the exact quote and how often it comes up.

For each buyer question, one row: the AI answer first, then where you rank on Google. You'll know if you're winning both, losing both, or ranking on Google while AI ignores you.
See which property portals, Reddit threads, YouTube walkthroughs, review sites and news articles shape what AI says, and which of them help your competitors. MentionX doesn't post on social media for you.
The Action Board turns each gap into one clear task, most important first. MentionX can draft the fix, such as a project page with current handover dates, an answer to an old forum thread, a LinkedIn carousel or a short video. Drafts go to your website for you to approve; nothing goes live on its own.
MentionX asks the same questions again every week, so you see whether AI's answers change over time. Board-ready slides and a shareable PDF are included.
Illustrative only, not a real result: Before: AI leaves you out and repeats a wrong fact. After the fix: the weekly re-check shows whether AI now names you and quotes the right facts, with the trend over time.
Keep doing it. But more and more buyers ask AI before they search, and AI gives a short list, not pages of results. Ranking on Google doesn't mean AI will name you. MentionX shows both, side by side.
No. MentionX checks ChatGPT, Gemini, Google AI Mode, Google AI Overviews, Perplexity, Microsoft Copilot and DeepSeek, and shows your Google rank next to each AI answer.
Every AI answer is saved word for word before anything is counted. You can open any number and read the answer behind it.
Plans start from $19.99/month (USD). One lost booking on one unit is worth far more than a year of MentionX.
You choose the questions, and German questions are fine.
Set up questions for Munich, Frankfurt, Hamburg, Stuttgart and others.
No. MentionX drafts the content. You review it and publish it yourself.
"I've spent 13 years helping businesses get found on Google. AI answers are a new problem on top of that: buyers make up their minds before they ever reach your website. I built MentionX so you can see what AI says about you and fix it." — Dipuck, founder of MentionX
We run 20 real questions German buyers ask, e.g. "bester Bauträger Stuttgart Neubau", on ChatGPT and Gemini, send a PDF report, and invite you to a short demo.
