AI visibility auditing for website access
isvisible.ai is a free AI visibility audit tool that checks whether major AI systems can reach a website. It focuses on access for search engines, AI training crawlers, and AI answer engines, then turns the result into a score and access map.
To run a check, you paste a URL and the service evaluates robots.txt, llms.txt, and live access from crawlers such as Googlebot, Bingbot, GPTBot, ClaudeBot, and PerplexityBot. The output is an instant 0-100 AI visibility score with an agent-by-agent breakdown, which is meant to show where a site is reachable and where it is blocked.
What isvisible.ai includes
13-crawler access map
The service checks whether access is allowed for 13 AI crawlers, including search, training, and answer-engine crawlers.
0-100 score with grade
The report shows an AI visibility score from 0 to 100 plus a letter grade, giving a quick summary of how accessible the site is to AI systems.
Agent-by-agent report
Reports break down access by crawler and show whether each one was allowed or blocked. The sample report also distinguishes robots.txt blocks from live request failures.
robots.txt and llms.txt analysis
The check evaluates robots.txt and llms.txt, then combines those signals with a live homepage probe using each crawler's user agent.
Shareable PDF output
The homepage says the report can be downloaded as a one-page PDF and is cached for 60 minutes.
Common ways to use isvisible.ai

Audit crawler access rules
An SEO or content lead can review robots.txt and llms.txt behavior alongside crawler-specific access to spot gaps that may affect AI-assisted search and answer surfaces.
Understand different AI access types
A marketer or publisher can compare training crawlers with answer engines to understand whether content is reachable for model training, live browsing, or citation in AI responses.
Verify technical crawl behavior

Share a concise report
A team can export or share the one-page PDF report as a compact snapshot of AI visibility for internal review.
