Ask questions, summarize, and edit PDFs for $40

TL;DR: Get lifetime access to PDF editor PDNob Pro for $39.97 (reg. $349.95) with code SAVE10.

PDFs are easy enough to open. However, working within them is when things start getting annoying. The PDNob Pro PDF Editor combines the usual editing and conversion tools with AI that can summarize documents, answer questions, and pull out key information. When you use the code SAVE10 at checkout, you can get the lifetime subscription for $39.97 through July 19 at 11:59 p.m. PT.

The AI tools are designed for PDFs that would otherwise take a while to work through. You can ask questions about reports, manuals, research papers, or contracts, get summaries of longer documents, and translate or rewrite content within the software. The lifetime plan includes 6,000 AI credits for these features.

PDNob also covers the less exciting but vital parts of dealing with PDFs. You can edit text and images without converting the whole file, merge or split documents, rearrange pages, add annotations, fill out forms, and sign files digitally. Conversion tools support Word, Excel, PowerPoint, text, and image formats.

For scanned documents, built-in OCR can turn image-based text into editable, searchable content. It can also enhance blurry scans, correct skewed pages, and process several PDFs at once. Batch tools are available for other repetitive jobs, including conversion and compression.

PDNob works across Windows, Mac, and iOS, rather than limiting you to one operating system. The plan supports simultaneous use on two devices and includes 20GB of lifetime cloud storage.

Students could use the AI tools to work through research papers, while freelancers and professionals may get more mileage from editing contracts, organizing client documents, or converting files. The lifetime plan also includes free updates, so there are no recurring subscription or upgrade fees.

If PDFs are a regular part of your work, PDNob Pro PDF Editor is available for $39.97 with the code SAVE10 through July 19 at 11:59 p.m. PT.
