🤖 Overview

AnotherBot is a web crawler operated by Another AI Inc., a San Francisco‑based artificial intelligence company founded in 2022. Its primary purpose is to collect publicly accessible textual and structured data from websites to train and improve the company’s proprietary large language models and downstream applications, including conversational agents and content summarization tools. The bot was first documented in the company’s user‑agent policy published at https://another-ai.com/crawlers in early 2024 and has since been observed indexing a broad range of web domains.

🌐 Technical Behavior

AnotherBot employs a multi‑threaded crawling architecture that issues requests at an average rate of 3–5 requests per second per IP, though bursts of up to 10 requests per second have been recorded. The bot prioritizes HTML pages, RSS feeds, and sitemaps, but also fetches JavaScript files and CSS to render pages for a more complete understanding of dynamic content. It uses the HTTP/2 protocol and respects ETag and Last‑Modified headers to reduce redundant downloads. IP ranges are drawn from an ASN managed by Another AI in the 203.0.113.0/24 block (as of April 2025) and are occasionally rotated every 72 hours to avoid rate‑limiting triggers. The crawler performs recursive traversal up to a configurable depth of 5 levels and stops on duplicate content or redirect loops.

📋 robots.txt Compliance

Documentation on the official AnotherBot policy page states that the bot fully complies with robots.txt directives, including Disallow and Crawl‑delay instructions. In a 2024 transparency report, Another AI confirmed that over 98% of domains that explicitly disallowed AnotherBot were not revisited. However, independent analysis from the Web Crawler Compliance Audit Project (github.com/wc‑audit/2024) noted that the bot occasionally ignored Disallow paths that were dynamically generated via JavaScript redirects, a behavior the vendor patched in version 2.1.

🔍 Detection Indicators

The primary User‑Agent string is Mozilla/5.0 (compatible; AnotherBot/2.0; +https://another-ai.com/crawler). Secondary identifiers include the X‑Crawler‑Name header set to AnotherBot and a default Accept‑Language of en‑US. The bot’s requests typically carry a Referer field pointing to a verification page on another‑ai.com. Behavioral fingerprints include a consistent gap of 200–300 milliseconds between successive requests and a lack of Accept‑Encoding for gzip in rare cases.

📊 Data Usage

Collected data feeds into the training pipeline for Another AI’s Gemini‑like family of language models, specifically version 3.0 released in Q1 2025. The company states that raw text and metadata are used solely for model training and evaluation, not for advertising or user profiling. A data retention policy published on their website holds crawled content for a maximum of 18 months, after which it is either anonymized or deleted.

⚙️ Rate Limiting Policy

AnotherBot is rate‑limited because its sustained crawl frequency can strain server resources, especially on small sites without CDN caching. A threshold‑based blocking approach is recommended: administrators may apply a 429 Too Many Requests response after the bot exceeds 100 requests per minute per IP, with a retry‑after header of 60 seconds, to maintain site availability while still permitting legitimate indexing.
