Use Case Recommendations
Best for: llms.txt Generator
llms.txt Generator turns a website's sitemap into a spec-compliant llms.txt file with AI-written descriptions for each page. llms.txt is a proposed web standard, created by Jeremy Howard of Answer.AI in late 2024, that gives large language models a structured markdown summary of a site — an H1 title, a blockquote summary, and grouped link sections with a short description beside each URL — so that a model answering a question about your business reads a curated map instead of guessing from whatever pages it happened to crawl. The generator's argument for why this matters is a direct comparison: without the file, an AI answering a question about a company produces something vague and generic; with it, the answer names the product, the pricing, the audience and the integrations correctly, because those facts were stated in a format built to be parsed. The tool crawls the sitemap, writes a description per page, and delivers a hosted file at a permanent URL with automatic regeneration on a schedule, plus email delivery and dashboard access. A free scan runs the first twenty URLs with AI descriptions and returns a full page count and AI-visibility audit with no signup. The site notes Google Lighthouse now audits llms.txt readiness.
Ideal use cases:
- •Teams or individuals who need spec-compliant llms.txt output: h1 title, blockquote summary, grouped link sections
- •Teams or individuals who need ai-written description for every page, generated from your sitemap
- •Teams or individuals who need hosted file at a permanent url with scheduled automatic regeneration
- •Teams or individuals who need free 20-url preview plus a full ai-visibility audit, no signup
- •Anyone focused on llms-txt workflows
- •Anyone focused on geo workflows
Best for: Otterly.AI
Otterly.AI monitors whether AI search engines mention your brand and cite your site, across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Gemini and Claude. The product is organised in three stages. Prompt research surfaces the prompts, topics and intent patterns that actually drive AI-generated answers in your category, so you are tracking real questions rather than guessing at them. Analytics then measures how your brand appears — or disappears — against competitors, with brand coverage over time, raw mention counts, average brand position and a brand visibility index, sliceable by branded versus non-branded, top versus bottom of funnel, engine and country across fifty-plus markets. Optimisation closes the loop with a generative-engine-optimisation audit, link-citation analysis, domain ranking and weekly recommendations. For teams building this into a workflow rather than a dashboard habit, the middle tier and above expose an API, an MCP server and agent analytics — the MCP surface in particular means the data is reachable from an agent rather than only from a browser. Agencies get unlimited workspaces and unlimited team members on every tier, which is unusual in a category that normally charges per seat. The vendor reports 30,000-plus marketing users and holds a Cool Vendor listing in an AI-in-marketing report.
Ideal use cases:
- •Teams or individuals who need tracking across chatgpt, ai overviews, ai mode, perplexity, copilot, gemini and claude
- •Teams or individuals who need prompt research surfacing the questions that drive answers in your category
- •Teams or individuals who need brand visibility index, average position and competitor comparison
- •Teams or individuals who need link citation analysis and generative-engine-optimisation audits
- •Anyone focused on geo workflows
- •Anyone focused on ai-search workflows
