About GEO Probe

GEO Probe is a workshop companion tool built by Agifly for the Agoria GEO Masterclass (21 May 2026). It fans a single prompt out to four generative-search engines — ChatGPT, Perplexity, Google Gemini and Claude (Anthropic) — in parallel, auto-detects brand mentions and citations, surfaces likely inaccuracies, and exports the results into the workshop's Prompt Test Capture XLSX template.

The tool is designed for the two live exercises in the masterclass: the Digital Twin Audit (Exercise 1) where each participant tests three protocol prompts about their own brand, and the Golden Source re-run (Exercise 5) where the same prompts are repeated after content interventions to measure movement. A free-form mode is also available for experimentation during breaks.

Privacy. Prompts and ground-truth fields are kept on your own device (browser localStorage) and are not stored on any server. Each prompt is, however, sent to the four model providers you have configured (OpenAI, Perplexity, Google, Anthropic) so that they can run search and return an answer. Please avoid pasting confidential customer data; use the official brand profile your marketing team is happy to see indexed.

Source & license. Built as a Next.js 14 app, source available to Agifly team members. For questions during the workshop ask Alain (alain@agifly.be).
