What is aiPDF?
aiPDF is an AI tool specifically designed for deep document comprehension, supporting various input formats such as PDF, EPUB, web page URLs, and YouTube videos. Users can ask questions about documents, extract key information, or generate contextually complete summaries at any time. All responses are verified against relevant passages in the original document and clearly labeled with specific sources. The system employs advanced machine learning algorithms and, after preprocessing the document, enables real-time dialogue while fully safeguarding user data privacy and security.

Frequently asked questions
Is my document data secure?
Document security is our top priority: data is stored encrypted and not used for training external models; data sent to OpenAI and other third parties is automatically deleted weekly.
Can free users permanently save their documents?
No. Free users are on the Playful tier, where documents are automatically retained in the database for one month before deletion; if longer retention is required, you’ll need to upgrade your subscription.
