Mintlify is a documentation platform that makes developer docs structured and machine-readable, including for LLMs and AI search agents. Geology is a Generative Engine Optimization platform that measures how AI engines describe your whole brand (not just docs) and ships the fixes that change those answers. Mintlify is for engineering and DevRel teams who want clean, AI-ready docs as a publishing surface. Geology is for marketing and growth teams who need to see and influence brand visibility across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews.
Different problems, different buyers, occasional overlap.

What Mintlify does
Mintlify is a modern documentation platform aimed at API-first companies. It hosts MDX-based docs, ships interactive components, and recently leaned into AI-friendly publishing: an `llms.txt` generator, AI search inside docs, and structured output that LLMs can ingest cleanly. Customers like Anthropic, ElevenLabs, and Cursor use it to publish API references and developer guides. Their homepage positions the product as documentation that's "loved by users and AI." G2 reviewers call out the publishing experience and the speed of rolling out a polished docs site; the trade-off is that it's a docs platform, not a marketing or visibility tool.
What Geology does differently
Geology answers a question Mintlify isn't built to answer: "what does ChatGPT actually say about us when a buyer asks?" The platform tracks brand visibility, citations, and positioning across the five major AI engines, then pairs that measurement with execution across the whole site, not just the docs subdomain. Page audits flag content the model is misreading. Prompt management captures the queries your buyers run. Content briefs turn gaps into work the team can ship. An agentic optimization layer applies the common fixes (schema, FAQ structure, internal linking) automatically. The scope is the brand and the buyer journey, not the API reference. If your docs are on Mintlify, that's a strong technical foundation. Geology measures whether that foundation is actually translating into visibility, then closes the loop on the marketing pages that aren't.
Pricing
Mintlify offers a free tier for small projects, paid plans in the low hundreds per month, and custom enterprise quotes for larger deployments. Geology is sold on a transparent subscription with public tiers, scoped to brand-level AI visibility rather than docs hosting. The two are complementary spends, not competing line items.
When Mintlify wins
If your priority is shipping a fast, polished, AI-readable developer docs site, Mintlify is the right pick. The MDX components, the llms.txt support, and the in-docs AI search are genuinely useful for any API-first company.
When Geology wins
If your priority is brand-level visibility in AI answers (across product, solutions, pricing, and case-study pages, not just docs), Geology fits. You get measurement across all five major AI engines plus the execution layer that turns visibility gaps into shipped fixes. Mintlify is a publishing surface; Geology is a measurement and optimization layer over the whole site.
