Use Case Recommendations
Best for: Not Human Search
Not Human Search is a search engine whose users are meant to be agents, not people, and a scoring tool for anyone who wants to be found by them. It indexes thousands of sites and ranks them on machine-readable readiness rather than on backlinks or bids — the stated rule is that organic rank is based on readiness and never on payment. Readiness is scored 0–100 across agentic signals an autonomous client actually needs to transact: whether an llms.txt exists, whether there is an OpenAPI description, whether an MCP server is exposed, whether Schema.org markup is present, and several more. That produces two distinct uses. If you are building an agent, you can search by category, protocol or the job the agent needs to complete and get back services it can genuinely call rather than marketing pages it would have to scrape. If you run a site, you can score it and see specifically which machine-readable affordance is missing, which is far more actionable than a generic SEO audit because the checks map one-to-one onto files you can ship. Browsing is organised by category — MCP servers, AI tools, developer, data, finance, e-commerce, productivity, security, health — plus top-100 and newest views. Search and scoring are free.
Ideal use cases:
- •Teams or individuals who need 0–100 agent-readiness score across multiple machine-readable signals
- •Teams or individuals who need checks for llms.txt, openapi, mcp endpoints and schema.org markup
- •Teams or individuals who need rank determined by readiness, explicitly never by payment
- •Teams or individuals who need thousands of agent-ready sites indexed and browsable
- •Anyone focused on agentic-web workflows
- •Anyone focused on llms-txt workflows
Best for: Zerply
Zerply is an AEO and SEO platform that closes the loop between measuring AI visibility and doing something about it, which is the gap most tools in this category leave open. The tracking half runs your prompts daily across ChatGPT, Google AI Mode, Google AI Overviews, Perplexity, Claude, Gemini, Copilot and Grok, reporting mention rate, stance, citation rate and share of voice against the competitors you actually lose to, with an industry ranking showing where you sit and how far each rival moved. The signals half traces the sources behind each answer, so a drop in mention rate resolves to which specific pages and citations stopped carrying you rather than to an unexplained number. Foundry is the part that acts: it publishes blog posts and landing pages onto your own domain, so the fix ships rather than sitting in a report. Separately, AI traffic analytics tracks the LLM crawlers themselves — GPTBot, PerplexityBot, ClaudeBot, Google-Extended — so you can see which are actually fetching your pages. The whole platform is exposed as an MCP server with nine tools, meaning an agent in Claude or Cursor can pull metrics, list citations and publish a post directly. Higher tiers add Claude, Meta, Kimi, Qwen, Mistral and DeepSeek API coverage on top of the consumer engines.
Ideal use cases:
- •Teams or individuals who need daily prompt tracking across chatgpt, google ai mode, perplexity, claude and more
- •Teams or individuals who need mention rate, stance, citation rate and share of voice with industry ranking
- •Teams or individuals who need source tracing that explains why visibility moved
- •Teams or individuals who need foundry publishes blog posts and landing pages to your own domain
- •Anyone focused on aeo workflows
- •Anyone focused on geo workflows
