GEO Tool vs Rank Prompt (2026)

GEO Tool's Paid GEO Audit starts at €299 (about $335) one-time, and its readiness check is free, with no signup, account or card. Rank Prompt runs from $49 a month for Starter, with 150 credits and 10 brands, to $299 a month for Agency Plus, with 2,000 credits and 1,000 brands. It keeps a standing free plan, and the 7-day trial of a paid tier asks for a card.

The free check scans one URL and returns a GEO Score from 0 to 100 in about 47 seconds, by the vendor's own timing. The vendor says the scan checks readiness signals and does not claim a live engine measurement. Claude, Copilot and Google's AI Overviews and AI Mode appear as targets the audit scores against, and Grok is not covered. Live answers, with cited sources and named competitors, are collected only in an early-access workspace that queries three surfaces.

Rank Prompt queries ChatGPT, Perplexity, Google AI Mode, Claude, Gemini and Grok on every plan. Copilot is not tracked. It reports mention rate and share of voice, names each cited domain and page, and detects competitors automatically, down to the sources that cite them and not you. Articles and audits draw on the same credits as prompt scans. One reviewer puts 10 prompts a day across all six engines at roughly 600 credits a month, four times what Starter holds.

Rank Prompt has a documented REST API even on its free plan. GEO Tool's public API carries only blog posts and an aggregate visibility index, not the page analysis. GEO Tool shows which AI crawlers your robots.txt permits and leaves log-file analysis to the paid audit. Rank Prompt counts AI referral sessions, not bot visits. GEO Tool's Berlin team sells audits, implementation and reporting as done-for-you work, while Rank Prompt quotes a separate engagement from $2,500 a month.
