# VectorGap

Local AI visibility, measured by city and by language.

## What it is

Maker-submitted description:

VectorGap measures what AI assistants answer when someone looks for a local professional or brand. We ask 8 buyer questions to 7 AI models (ChatGPT, Claude, Gemini, Perplexity, Grok, Mistral, Muse Spark by Meta), first without web search, then with live web search, in each language the market speaks: French, Dutch, German or English. The report shows whether the business is named, what the models say about it, and who they recommend instead. Every result carries its date, and the Brand Snapshot includes a re-measurement after 30 days. VectorGap works with marketing and SEO agencies that serve local businesses, through a partner program, and directly with multilingual brands. Founded by Johnny Lagneau in May 2026 and based in Brussels, Belgium. Public measurements: city pages for Paris, Brussels, Luxembourg and Montreal at vectorgap.ai/ia-locale, and a monthly barometer of Belgian e-commerce brands at vectorgap.ai/barometre.
