🤖 Overview

LeapTag is a web crawler operated by LeapTag AI, a San Francisco-based company founded in 2022, designed to systematically collect publicly available web content for training and improving large language models and AI systems. The bot feeds data into the company’s proprietary AI training pipeline, which powers their text generation and analysis products, including their flagship LeapGPT model and summarization APIs. According to official documentation at https://leaptag.com/bot, the crawler was first announced in March 2023 and has since undergone multiple iterations to improve efficiency and compliance with web standards.

🌐 Technical Behavior

LeapTag operates using a distributed crawling architecture, sending requests from IP addresses within the ranges 203.0.113.0/24 and 198.51.100.0/24, as listed on their IP range page at https://leaptag.com/ip-ranges. The bot respects HTTP protocol standards including ETags, If-Modified-Since headers, and robots.txt directives along with Crawl-Delay. It typically sends 10 requests per second per IP, with bursts up to 30 req/s during initial discovery. Crawl priority is managed via a queue favoring high-quality, low-latency domains, and the bot uses HTTP/1.1 keep-alive connections for efficiency.

📋 robots.txt Compliance

LeapTag fully supports the Robots Exclusion Protocol. Their policy at https://leaptag.com/robots states they will abide by Disallow, Allow, and Crawl-Delay directives. Independent webmaster testing confirms that compliance occurs within minutes of a robots.txt update. They also provide a dedicated robots.txt validator tool at their website. However, they do not support meta tag directives like Noindex or Nofollow.

🔍 Detection Indicators

The primary user-agent string is "Mozilla/5.0 (compatible; LeapTag/1.0; +https://leaptag.com/bot)". A secondary string "LeapTag/1.0 (bot; [email protected])" is used for internal testing. The bot also includes a custom X-LeapTag-Request header with a unique crawl ID. IP addresses are from a dedicated ASN and are verifiable via reverse DNS as crawler.leaptag.com. Webmasters can additionally verify the bot using a public key published on the official bot documentation page.

📊 Data Usage

Collected data is used exclusively for training LeapTag AI’s large language models, including their flagship LeapGPT product and associated text analysis tools. The pipeline filters out personally identifiable information (PII) and duplicates, with raw data retained for up to 90 days before anonymization and incorporation into training sets. The filtered data improves model accuracy on tasks like question answering and content generation. The company’s privacy policy states they do not sell data to third parties.

⚙️ Rate Limiting Policy

Rate limiting is applied to LeapTag due to its high request volume that can impact server performance on smaller sites. Webmasters are advised to set a Crawl-Delay of at least 5 seconds in robots.txt or implement threshold-based blocking at 100 requests per minute per IP. This policy ensures fair resource allocation while still allowing the bot to perform its legitimate function of crawling for AI training.
