PDNob AI goes beyond basic Q&A by integrating a pro-grade AI OCR engine with DeepSeek R1 & ChatGPT dual models. It accurately recognizes scanned documents and screenshots, providing precise source tagging in answers for reliable document analysis.
Simply download and install PDNob, open your PDF, and click the AI icon. Guests and free users get 50 AI credits instantly to explore all features—no credit card required. To unlock 6,000 credits and large file support, upgrade to the Lifetime Plan.
We integrate two of the most powerful models: ChatGPT-4o (for fluent writing and translation) and DeepSeek R1 (for deep logical reasoning and technical analysis). You can switch between them based on your task.
PDNob AI features "Source Tagging." Whenever it provides an answer, it cites the original location and page number. Clicking the tag auto-navigates you to the corresponding paragraph in the PDF for instant verification.
No. A single Lifetime account allows you to log in and access AI credits and features across multiple platforms, enabling a smart workflow on all your devices.
Absolutely. We use enterprise-level encryption to protect your documents during analysis. Your private files and AI conversations are never used to train public models, ensuring your sensitive information remains secure and confidential.
Yes. Our integrated pro-grade AI OCR engine allows PDNob AI to "read" and analyze scanned documents and screenshots. This ensures you can chat with and extract insights from any non-searchable file just as easily as a standard PDF.
It depends on your task. Use DeepSeek R1 for complex logical reasoning and technical data extraction, or switch to ChatGPT-4o for natural language fluency, creative rewriting, and nuanced translations to get the best results.
