Geology and PromptWatch overlap on prompt monitoring, then diverge sharply. PromptWatch is a focused brand-monitoring tool that watches how your name appears across prompts and answers in the major AI assistants. Geology is an AI-driven SEO and GEO agency: the same monitoring across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews every week, plus AI agents and a team that ship the technical SEO, content, schema, internal linking, and off-site citation work that changes what the assistants say.
If you want a lightweight prompt watcher for a PR team that handles everything else itself, PromptWatch does that job. If you want the watching plus the work that closes the loop, Geology does both.

What PromptWatch does
PromptWatch is a brand-monitoring product purpose-built for the AI assistant era. It runs your tracked prompts on a schedule against ChatGPT, Perplexity, Gemini, and Copilot, captures the answers, and flags whether your brand (and competitors) appeared, in what position, and with what sentiment. Reports surface share of voice across prompts, citation sources, and changes over time. The tool is light on setup, opinionated about prompts as the unit of measurement, and reads as a focused alternative to broader analytics suites. PR and brand teams use it as a daily pulse on AI mentions, similar to how a media monitoring tool works for traditional press. The boundary is clear: PromptWatch measures and alerts. The work of changing what the models say (page rewrites, schema, FAQ structure, citation building) sits with your content team.
What Geology does differently
Geology covers the same prompt-level monitoring and then does the work the data points to. Page audits flag which pages an AI model is misreading and explain why. The team turns mention gaps into content with target prompts and angles built in, then writes and publishes it. AI agents apply the structural fixes that consistently move citations: schema markup, FAQ blocks, internal linking, citation hygiene, and answer-shaped copy. Off-site citation work builds the sources AI engines pull from, and tracking includes Google AI Overviews alongside the four assistants. The thesis is direct. Mention dashboards are the easy half of GEO. The hard half is making the changes that bring the mentions back. Geology runs both halves, so insight-to-shipped-fix happens in days, not quarters. For a California-licensed specialty insurance broker, that took the brand from absent to named in 70% of tracked AI answers in six months.
Pricing
PromptWatch is sold on a subscription with tiers scaled by tracked prompts, brands, and refresh frequency. Geology starts at $3,000 a month and covers the execution, not only the monitoring. For a single brand running a narrow mention watch with in-house staff doing the fixes, PromptWatch is lower-priced and narrower. For teams that want the results, Geology bundles monitoring and shipped work in one engagement.
When PromptWatch wins
If your PR team only needs a daily alert feed on how the brand surfaces in AI assistant answers, with sentiment, and already has content and engineering staff to do any fixes in-house, PromptWatch is an easy-to-deploy monitoring tool for that setup.
When Geology wins
If the dashboard creates an action backlog you struggle to clear, Geology wins. You get prompt monitoring plus a team and AI agents that ship the audits, content, and fixes that turn mentions into change. For teams that need to move metrics this quarter, the closed loop is the differentiator.
