I pay for Adobe AI. It says that it can analyze a document up to 600 pages. I upload a document that is less than 500 pages and it will answer questions once or twice, then it fails. It says that it can't be used to analyze my document and can only analyze documents less than 200 pages. Honestly, the AI is very slow compared to other free options on the internet, and less insightful as well. I don't think this product is ready for prime time, and definitely not to the point where you should be charging people money for it.
