LogSlicer identifies 60+ bots across LLM training, search engines, SEO tools, social preview bots, and monitors — down to the exact user agent string.
GPTBot, ChatGPT-User, OAI-SearchBot, ClaudeBot, PerplexityBot, Bytespider — see exactly which AI systems are requesting your pages and where they hit redirects or errors.
