Why we built these tools
AI search is now a top-of-funnel channel for most sites, but the scaffolding it depends on — llms.txt, AI-aware robots.txt, FAQ JSON-LD, ai-plugin.json — is missing on most of the web. So we built clean, free versions of the five files you actually need. Fill in a form, get a valid copy-ready file, ship.
Ship them in this order
AI-aware robots.txt
The gate. Sets crawler permissions for GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended and more. Get it wrong and nothing downstream matters.
llms.txt
A Markdown brief at your domain root pointing AI models at your canonical pages — the executive summary you'd hand an analyst.
JSON-LD schema
Organization on every page; Article on posts; Product on PDPs; FAQPage on Q&A. How AI engines verify what your pages are about.
FAQ schema
Highest-leverage schema for AI Overviews and chat-assistant citations. Build it for your top 5–10 pages.
ai-plugin.json
Only if you have an API worth exposing. Hosted at /.well-known/ai-plugin.json so agent frameworks discover it.
How each AI engine reads your files
Match the right file to the right crawler. An hour spent here saves months of guessing why citations aren't moving.
| Crawler | Owner | robots.txt | llms.txt | JSON-LD |
|---|---|---|---|---|
| GPTBot | OpenAI | |||
| OAI-SearchBot | OpenAI | |||
| ClaudeBot | Anthropic | |||
| PerplexityBot | Perplexity | |||
| Google-Extended | Google (Gemini, AI Overviews) | |||
| Applebot-Extended | Apple Intelligence, Siri | |||
| CCBot | Common Crawl |
A pragmatic order for a busy team
robots.txt
Allow GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended. Add sitemap directive. Push to /robots.txt.
llms.txt
Short, opinionated: H1 brand, blockquote summary, ## Docs list of ten canonical pages. Push to /llms.txt.
Organization JSON-LD
One block in your site-wide template. Gives every AI engine a verified brand entity to attach citations to.
FAQ JSON-LD ×5
Pricing, home, top blog post, primary product page, contact. Four to eight real Q&A pairs each.
Mistakes we catch every week
A wildcard Disallow: / for User-agent: * also catches every AI crawler. Six months of zero ChatGPT citations follow.
A 301 from /llms.txt reads as 'file missing' to most AI crawlers. The file must live at the root.
Some CMSes wrap files in an HTML shell. curl -I should return text/plain or text/markdown — not text/html.
Engines spot-check rendered HTML. Mismatch = schema ignored, sometimes for the whole domain.
Half the URLs 404. Engines learn to distrust the file and de-rank everything in it.
Every acronym, defined
These generators produce files. They don't crawl your site, audit your existing schema, check whether your pages are actually cited by AI engines, or monitor for drift over time. That's what the full OptimAIze scan does — also free. Generate your files here, then run a scan to verify they're discoverable and that the rest of your site is pulling its weight.
Want the full audit, not just the files?
OptimAIze scans your whole site, validates the files you just generated, and shows you exactly which AI engines can read what — in under 60 seconds.
Run a free scanFrequently asked questions
Are these tools really free?
Yes. Every generator on this page runs entirely in your browser, no signup, no rate limits, no email required. We ship them because making the web AI-readable is upstream of the audit business we run — the more sites publish proper llms.txt, FAQ schema, and AI-aware robots.txt, the healthier the AI search ecosystem becomes.
Which file should I publish first?
Start with an AI-aware robots.txt — that one decides whether GPTBot, ClaudeBot, PerplexityBot, and Google-Extended can read your site at all. Then publish an llms.txt at your domain root to point engines at your best pages. After that, add FAQ JSON-LD to your highest-intent pages (pricing, docs landing, top blog posts) so AI engines can lift answers verbatim.
Do I need all five files?
Most sites benefit from llms.txt, AI-aware robots.txt, and FAQ + Organization JSON-LD. ai-plugin.json only matters if you expose a real API that agents can call (search endpoints, lookups, transactional actions). Product JSON-LD only matters for e-commerce. Pick what fits your stack — they all stack additively.
Will Google penalize me for adding AI files?
No. None of these files conflict with Google ranking signals. robots.txt rules for AI bots are independent of Googlebot, llms.txt is ignored by classic search, and JSON-LD has been a Google-recommended format since 2015. The only risk is over-promising in schema (e.g. fake reviews) — which is the same risk that already existed.
How do I know my files are working?
After publishing, run a full OptimAIze scan on your domain. The scanner fetches each file the way AI crawlers do, validates structure, checks discoverability, and tells you which AI engines can actually parse what you shipped. It's the verification step the generators don't do.
What's the difference between llms.txt and sitemap.xml?
sitemap.xml is an exhaustive machine list of every URL for search-engine indexing. llms.txt is a short, curated, human-readable brief for AI models — it picks your canonical pages and explains the site in plain English so LLMs can quote you accurately. They serve different jobs and both should exist.
Boost Your AI-Search Presence with OptimAIze Free Tools
OptimAIze offers a suite of free, powerful tools designed to elevate your content's visibility within the rapidly evolving AI-search landscape. These utilities directly address common challenges in SEO/AEO, from schema validation to content optimization. By leveraging these tools, you can ensure your digital assets are not only discoverable by traditional search engines but are also explicitly understood and prioritized by advanced AI crawlers like GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, and Google-Extended, which power generative AI experiences. Integrating them into your workflow provides a strategic advantage, transforming how AI finds, interprets, and cites your information. Begin by identifying your specific content or schema deficit, then select the tool best suited to resolve it.
Schema Validator: The Foundation of AI Understanding
The Schema Validator is crucial for ensuring your structured data speaks the language of AI. Problem: Your existing schema might be malformed, incomplete, or incompatible with modern AI-search requirements, leading to poor data extraction by crawlers. Workflow: Use this tool after implementing any Schema.org markup (e.g., Article, Product, LocalBusiness). It identifies errors, missing properties, and provides actionable fixes. Output Change for AI Crawlers: A valid schema means GPTBot and OAI-SearchBot can accurately extract facts, attributes, and relationships from your page, increasing the likelihood of direct answers and featured snippets. It ensures Google-Extended reliably parses your content for AI summarization and answer generation, setting your content apart from competitors with invalid or absent schema.
Content AI-Readiness Checker: Optimizing for Generative AI
The Content AI-Readiness Checker is designed to assess how well your page content aligns with the expectations of generative AI. Problem: Your content might be verbose, lack clear answer-first phrasing, or fail to directly address user queries, making it difficult for AI to summarize or quote. Workflow: Apply this tool to key informational or commercial pages post-drafting. It analyzes clarity, conciseness, and directness, suggesting improvements for AI summarization. Output Change for AI Crawlers: For ClaudeBot and PerplexityBot, highly AI-ready content translates into more accurate summaries, direct quotes, and improved answer generation. This tool aims for a 'clarity score' above 85%, ensuring AI can quickly identify and utilize your core message, making your content a preferred source for AI responses. Google-Extended will also prioritize such content for training and real-time query responses.
Local Business SEO Scan: Dominating Local AI Search
The Local Business SEO Scan is vital for businesses relying on local visibility within AI-driven search. Problem: Inconsistent NAP (Name, Address, Phone) data, unoptimized local schema, or missing Google My Business (GMB) connections hinder local AI-search performance. Workflow: Run this scan quarterly for local businesses or whenever location details change. It scrutinizes your NAP consistency across the web, validates LocalBusiness schema, and suggests GMB optimization. Output Change for AI Crawlers: For GPTBot and OAI-SearchBot, consistent NAP and valid LocalBusiness schema (e.g., `@type": "LocalBusiness"`) directly inform geo-specific queries. This increases the chance of your business being cited for "near me" searches by AI assistants. Google-Extended uses this data to provide highly relevant local recommendations and direct users to your establishment, significantly boosting GEO visibility thresholds.
