AIAZHHow To Use
- Enter Your Site URL — Type your website address to set the domain for your robots.txt. No server upload — everything stays in your browser for complete privacy.
- Add Crawl Rules — Add Allow or Disallow paths for each user-agent. Block directories like /admin/ or /private/ from search engine indexing.
- Block AI Crawlers — Optionally block AI training crawlers like GPTBot, ClaudeBot, and Google-Extended to prevent your content from being used in LLM training datasets.
- Include Sitemap — Add your XML sitemap URL so search engines discover all your important pages faster through the Sitemap directive.
- Generate & Deploy — Click generate, copy the output, and save as robots.txt in your site root. Keep it private — your rules and data are never stored or tracked.
Frequently Asked Questions
What is a robots.txt generator online and how does it work?
A robots.txt generator online creates a robots.txt file for your website without requiring you to write code. You configure allow and disallow rules visually through a form interface, and the tool outputs properly formatted text following the Robots Exclusion Protocol (RFC 9309). The file tells search engine crawlers like Googlebot and Bingbot which parts of your site they can and cannot access.
How do I use a robots.txt builder to set allow and disallow rules?
A robots.txt builder lets you add User-agent directives followed by Allow and Disallow paths. For example, set User-agent: * with Disallow: /admin/ to block all crawlers from your admin area. Use Allow: / to give specific crawlers full access. The builder handles the syntax automatically so you never need to memorize the format.
How do I block AI crawlers in my robots.txt file?
To block AI training crawlers, add User-agent directives for GPTBot (OpenAI), ClaudeBot (Anthropic), Google-Extended (Gemini training), and CCBot (Common Crawl), each followed by Disallow: /. This prevents these bots from accessing your content for training datasets while keeping search engine crawlers like Googlebot unaffected. Blocking AI crawlers is one of the most important robots.txt updates for website owners in 2026.
What are the most common robots.txt rules for my website?
Common robots.txt rules include: Disallow: /admin/ to block admin panels, Disallow: /search/ to prevent search result pages from being indexed, Disallow: /private/ for sensitive directories, Disallow: /*.pdf$ to block PDF files, and Sitemap: https://example.com/sitemap.xml to help crawlers discover pages. For WordPress sites, also consider Disallow: /wp-admin/ and Allow: /wp-admin/admin-ajax.php.
Is my data kept private when using this robots.txt generator?
Yes. All robots.txt generation happens locally in your browser. Your site URLs, directory paths, and rule configurations are never uploaded to any server. This means you can safely generate files for staging sites, private intranets, and pre-launch projects without exposing sensitive information about your site structure.
What Is a Robots.txt Generator Online?
A robots.txt generator online is a web-based tool that creates a robots.txt file for your website through a visual interface. Instead of manually writing User-agent and Disallow directives, you select crawlers, enter paths, and toggle AI blocks using checkboxes and text fields. The tool then generates a properly formatted robots.txt file following the Robots Exclusion Protocol (RFC 9309). This file tells search engines like Google, Bing, and Yahoo which pages to crawl and which to avoid, helping you manage crawl budget and protect private content.
Building Allow and Disallow Rules with a Robots.txt Builder
A robots.txt builder simplifies the process of creating crawl rules by providing a form-based interface for each directive. You can add multiple User-agent groups targeting different crawlers — for example, a wildcard group for all bots and a separate Googlebot group with specific permissions. The Disallow directive blocks specific paths, while the Allow directive overrides broader blocks for individual files or subdirectories. Rules follow longest-match precedence, where the most specific path pattern wins. This builder ensures your syntax is always correct, preventing common mistakes like missing colons, incorrect path formats, or rules placed before a User-agent declaration.
How to Block AI Crawlers in Your Robots.txt File
Blocking AI crawlers has become essential for website owners who want to prevent their content from being used to train large language models. Dedicated user-agent tokens now exist for all major AI vendors: GPTBot for OpenAI training, Google-Extended for Gemini and Vertex AI, ClaudeBot for Anthropic, and CCBot for Common Crawl datasets. Adding Disallow: / under each of these user-agents tells well-behaved AI crawlers to stay out. Importantly, blocking Google-Extended does not affect your Google Search rankings — Googlebot remains unaffected. This robots.txt rules creator makes it easy to toggle these AI crawler blocks on or off.
