Choose PDFbat if
- you want to act on what the AI finds: edit, redact, translate or sign the PDF.
- you work with scans, invoices or contracts and need structured output.
- you want credit packs that never expire and a free monthly allowance.
- you want an API or MCP server so other AI assistants can use PDF tools.
Choose ChatPDF if
- you only want a minimal chat window and nothing else.
- you ask questions about many documents and like its simple flow.
- you do not want a full PDF suite and prefer a single purpose tool.
- its current limits and pricing already fit your usage.
What the AI can do with your document
A chat box answers questions, but many tasks need an output file. With AI PDF, you can turn a stack of invoices into a CSV, translate a 40 page report into a new PDF, or run a contract review that lists parties, key dates, amounts, renewal terms and risks with the page each appears on.
Because it sits next to the PDF editor, AI can also help edit the document in the editor and draft new documents in Create.
How credits work
Each AI action costs credits based on its size, not a fixed number of actions a day. Free accounts get 200 credits a month and Pro gets 4,000. Packs add more: $5 for 5,000, $10 for 12,000 and $25 for 32,000, and they never expire. See pricing.
Where ChatPDF has the edge
ChatPDF is simple and was one of the first tools of its kind, so it is familiar to many users. PDFbat is newer and broader, which means more screens to learn if you only want a chat window. You can also link PDFbat tools to Claude and other assistants through the MCP server.
