Doxy vs pdfAssistant.ai

Supported inputs include PDFs, Word, PowerPoint, Excel, images, audio, HTML, CSV, ZIP and EPUB files, plus web links and YouTube URLs. YouTube questions use the video transcript. Users can upload and ask questions in many languages, with answers in the question’s language where the source supports it. Pro and Business plans generate multiple-choice quizzes with explanations and open-ended practice exercises from selected sources. The Free plan costs nothing for 3 documents, 20 questions monthly and 10 MB files. Pro costs $4.99 a month for 100 documents, 1,000 questions monthly and 50 MB files. Business costs $9.99 a month with unlimited documents and questions and 200 MB files. An account is required.

pdfAssistant.ai is a web-based, no-code PDF platform that turns natural-language requests into reusable workflows for batch processing. It provides more than 40 operations, including compression, merging, extraction, redaction, conversion, and watermarking. Saved workflows can run on uploaded folders containing hundreds or thousands of documents. AI Studio handles one-off analysis, summaries, key-term extraction, and PDF creation from descriptions. The service supports multiple PDFs per chat and scanned PDFs, with exports including PDF, DOCX, XLSX, PPTX, Markdown, PDF/A, PDF/X, PNG, JPEG, TIFF, GIF, BMP, FDF, XFDF, XML, XDP, and XFD. MCP integrations are listed for ChatGPT, Claude, and Codex, but require a paid plan. Adobe Express add-ons export PDF/X, PDF/A, or custom images. Starter is free with preview mode; full downloads require payment. The maker says transfers use TLS 1.3, stored files use AES-256, and files are deleted within 24 hours.
