Dru from Diffbot here.<p>Sorry to hear about the issues you ran into when trying out Diffbot! If you have some examples, I&#x27;d like to take a look into whether we can improve.<p>In cases where our automatic extraction using computer vision isn&#x27;t 100% accurate, we offer a visual interface for actually overriding our default extraction. This input is then used as additional training data for the ML models.<p>Mozenda et al. are great if you only need data from a couple of sites and you don&#x27;t mind spending time manually specifying and maintaining CSS selectors for each website and page layout you need data from.<p>Our crawling, and proxy support, is fairly robust thanks to our hiring the creator of Gigablast [<a href="https:&#x2F;&#x2F;gigaom.com&#x2F;2013&#x2F;09&#x2F;10&#x2F;diffbot-brings-big-time-search-poobah-aboard-to-help-it-scale&#x2F;" rel="nofollow">https:&#x2F;&#x2F;gigaom.com&#x2F;2013&#x2F;09&#x2F;10&#x2F;diffbot-brings-big-time-search...</a>].<p>If you&#x27;d like to give Diffbot another go or you have some examples where the extraction could be improved, please let me know!
