Mintlify is a documentation platform that makes developer docs structured and machine-readable, including for LLMs and AI search agents. Geology is an AI-driven SEO and GEO agency: AI agents run strategy and execution, and our team ships the technical SEO, content, schema, internal linking and off-site citation work across your whole brand (not just docs), then tracks visibility weekly across ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews. Mintlify is software for engineering and DevRel teams who publish docs. Geology is the agency for marketing and growth teams who need their brand to show up in search and AI answers.
Different problems, different buyers, occasional overlap.

What Mintlify does
Mintlify is a 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 service.
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, and how do we change it?" AI agents track brand visibility, citations, and positioning across the five major AI engines and map the queries your buyers run. Our team then does the work across the whole site, not just the docs subdomain: technical SEO, content for product, solutions and comparison pages, schema, FAQ structure, internal linking and off-site citations. The scope is the brand and the buyer journey, not the API reference. If your docs live on Mintlify, Geology checks whether they are being cited and fixes the marketing pages and off-site signals that decide whether buyers hear your name.
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 starts at $3,000 a month for SEO and GEO strategy, execution and weekly reporting. The two are separate spends, docs hosting versus search growth, not competing line items.
When Mintlify wins
If you need a docs hosting platform for your engineering team, with MDX components, llms.txt support and search inside the docs, Mintlify is a docs build tool for that job. Geology does not host documentation.
When Geology wins
If your priority is brand-level visibility in search and AI answers (across product, solutions, pricing, and case-study pages, not just docs), Geology fits. You get weekly measurement across all five major AI engines plus the team that ships the fixes. For a mid-size B2B SaaS company, that work produced 65% organic growth in six months.
