Instead of ChatPDF
ChatPDF alternatives
ChatPDF makes it easy to summarize PDFs and ask questions in a conversational format, with citations that point back to the document. It supports multiple PDFs in one conversation, accepts several file types beyond PDF, and can chat in any language. Sharing controls and document deletion add options for managing access. The free plan allows two documents per day; ChatPDF Plus has no price stated. Readers can use it through a browser or its mobile and desktop platforms, and its API supports custom PDF chatbots.

An alternative may suit you better if your work centers on editing files, extracting structured data, searching scientific literature, or processing documents locally. Compare whether you need conversational answers or document operations, which formats and platforms matter, and whether citations, OCR, integrations, or automation are priorities. Pricing also differs: some alternatives have free plans and paid tiers, while Docling is open source. A tool built for a narrower task may be a better fit than ChatPDF’s general document chat.
