DeinPDF vs Doxy

DeinPDF is a browser-based assistant for asking questions about contracts, invoices, letters, and technical documents. Users can upload PDFs and images, including scanned pages, then ask questions across one or several documents in a temporary chat with page references. The service can summarize long documents and translate them into more than 16 languages. Suggested actions can help surface legal risks, deadlines, payment terms, action items, and obligations, or explain documents in simpler language. In instant mode, the file, index, and chat are erased after the conversation, with confirmation. The maker says documents are stored in Germany and AI processing takes place in the EU, with no transfer to third countries; it also says user documents and inputs are not used to train models. Security features listed include two-factor authentication, SSL/TLS encryption, and tenant isolation. DeinPDF works in a browser and can be added to an iPhone or Android home screen without an app store. There is no monthly base fee or forced subscription. Usage-based charges apply, with €0.50 starting credit and top-ups from €10. The terms warn that AI output may be incorrect or misleading and does not replace professional advice.

Doxy is a web document-chat app for asking questions about uploaded files and other source material.
