For everyday users who need to chat with PDFs and extract information from documents, PDF.ai is the clear winner—it's simple, focused, and works out of the box. Cohere is a powerful enterprise LLM platform for developers building custom search or summarization features, but it's overkill and too technical for most non-technical people. The single biggest difference: PDF.ai is a ready-to-use app, while Cohere is a developer toolkit that requires coding.

Common questions
No. For a single PDF, PDF.ai is much easier—just upload and ask. Cohere requires you to write code to send the PDF text to its API, which is overkill for one document.
Neither has a mobile app. PDF.ai works in a mobile browser reasonably well. Cohere is not designed for phone use at all—it's a developer API.
Neither is cheap for casual use. PDF.ai's free tier is very limited, and its paid plan is pricey if you only use it once a month. Cohere's free tier has heavy rate limits, and pay-as-you-go costs add up quickly for general chat.
Yes, that's exactly what Cohere is built for. You can use its Command R+ model and tool-use features to create a custom chatbot. But you'll need a developer to set it up.
Yes, PDF.ai has excellent OCR that handles scanned documents and images with text. It's one of its strongest features.
PDF.ai is better for this. Its multi-document feature lets you upload several contracts and ask questions across all of them, with page citations. Cohere could do this too, but you'd have to build the comparison logic yourself.
PDF.ai wins for everyday document chat; Cohere is for developers building custom AI features.
If you just want to upload a PDF and ask questions without any fuss, go with PDF.ai—it's simple, accurate, and shows you the source. If you're a developer looking to build custom AI features into your own app or website, Cohere is a powerful choice, but be ready to write code and manage costs. For most everyday people, PDF.ai is the practical pick.
