robots.txt Generator
Build, edit, validate, and test robots.txt rules for search engines, AI discovery, model training, and user-requested agents.
How to use
- Choose a starting template or import an existing robots.txt file.
- Build user-agent groups and set separate policies for AI discovery, training, and user-requested crawlers.
- Test important URL paths and resolve validation errors or warnings.
- Review the editable source, then copy or download robots.txt.
Example
Input
Allow AI search crawlers, block model-training crawlers, protect /admin/, and add a sitemap
Output
A validated robots.txt file with a tested crawler policy.
What robots.txt Generator returns
robots.txt Generator is designed to build and verify crawler directives for search engines, AI discovery, model training, and user-requested agents.
Input: templates or imported source, user-agent groups, allow/disallow paths, sitemap URLs, and purpose-specific AI crawler policies. Output: an editable and validated robots.txt file with path-test results.
How robots.txt Generator works
The builder creates RFC-style groups, preserves protected paths in explicit crawler groups, validates the editable source, and applies longest-match testing to a selected URL path.
Test representative public, private, asset, and query-string paths for the wildcard group and every crawler with a specific policy.
A useful situation for robots.txt Generator
Use it when you are keeping public pages discoverable while protecting operational paths and separating AI answer visibility from model-training permission.
The workflow is intended for site owners, SEO specialists, developers, content teams, and privacy-conscious operators.
Limits and common errors
Robots.txt is public and advisory, does not reliably prevent indexing, and may not control user-triggered fetchers.
A common mistake is using one blanket AI switch even though search, training, and user-requested fetchers publish different tokens and may follow different rules.
Privacy and the next step
Generation, imported-file parsing, validation, and path testing run locally without requesting the website.
For a broader workflow, pair the crawler policy with page-specific schema for machine context and Open Graph tags for social sharing.
If the result matters later, review official crawler definitions and retest important paths whenever search or AI access policy changes.
FAQ
Does robots.txt guarantee crawler behavior?
No. It is a public directive that reputable crawlers usually follow, not an access-control system.
Can I allow AI search while blocking model training?
Yes. Providers publish separate crawler tokens for search, training, and sometimes user-requested retrieval, so each purpose can have its own rule.
Does robots.txt prevent a page from being indexed?
Not reliably. Use a robots meta tag, X-Robots-Tag, authentication, or another appropriate access control when indexing or privacy must be prevented.
Is robots.txt Generator free to use?
Yes. The public robots.txt Generator runs in the browser and does not require a sign-in for normal use.
How does robots.txt Generator handle my input?
Generation, imported-file parsing, validation, and path testing run locally without requesting the website.
What should I check before relying on the result?
Test representative public, private, asset, and query-string paths for the wildcard group and every crawler with a specific policy. Also confirm that the input reflects the exact situation you are working on.
What is a common mistake with robots.txt Generator?
A common mistake is using one blanket AI switch even though search, training, and user-requested fetchers publish different tokens and may follow different rules. Review the original material and the final output before publishing or sharing it.
What should I use with robots.txt Generator?
Pair the crawler policy with page-specific schema for machine context and Open Graph tags for social sharing. Related tools can help you check the same task from another angle.
