About AI PDF Classifier
When documents arrive in bulk, figuring out what each one is, an invoice, a contract, a resume, a report, takes time you would rather spend elsewhere. The AI PDF Classifier reads a document and works out what category it belongs to, so you can sort incoming files automatically instead of opening each one.
Upload your PDF and the tool analyzes the content and assigns it a category that fits. It is free, browser-based, asks for no signup, and your file is processed only for the classification and not stored. It is a practical way to triage a stack of mixed documents, and since it bases its call on the text, clear, text-based PDFs give the most dependable results.
