Use Case Recommendations
Best for: Linksii
Linksii tracks how ChatGPT, Claude, Gemini, and Perplexity answer the buying questions in your category. You define the prompts your customers actually ask — natural-language questions rather than keywords — and each one is re-run daily across all four assistants. The output is four linked views: a Brand Visibility Score that rolls up into one number and breaks down per platform; position tracking showing where you rank against named competitors inside a given answer; sentiment analysis splitting positive, neutral, and negative framing; and source citations showing which domains the models are drawing on, tagged by type (corporate, editorial, UGC). Prompts can be tagged by category and funnel stage, so you can see which stage you win and where you disappear. A competitive benchmark view charts your score against specific competitors over 7, 30, and 90 days. Linksii's own positioning argument is against the category norm of gating the useful parts: all four assistants and daily re-runs are included on every plan including the trial, on the reasoning that cross-platform variance is the most diagnostic signal available. It publishes a public research report, The State of AI Search Visibility 2026, covering 200 brands and 1,072 data points, and runs a free no-signup visibility check that returns in about 40 seconds.
Ideal use cases:
- •Teams or individuals who need daily prompt re-runs across chatgpt, claude, gemini, and perplexity on every plan
- •Teams or individuals who need brand visibility score with a per-platform breakdown
- •Teams or individuals who need position tracking against named competitors inside ai answers
- •Teams or individuals who need sentiment analysis and source-citation tracking by domain type
- •Anyone focused on geo workflows
- •Anyone focused on ai search workflows
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
