ExplainThisDoc: PDF & Archive

Keep letters, bills, and PDFs together. Find your documents again and get difficult letters explained whenever you need help understanding them. ExplainThisDoc helps you keep personal paperwork handy on your iPhone and iPad without maintaining a folder system. Explanations, personal notes, and linked documents stay together.

Your archive and everyday document tools are free. Only Pro explanations use credits: one credit per analysis. No subscription.

COLLECT AND FIND
Scan your letters, documents, and paperwork with your camera, or import PDFs, photos, and supported files already saved on your phone, attached to emails, or shared by other apps. You can also add text from the clipboard. Use search and filters to find documents in your archive. Link related documents, such as a contract and its invoice.

WORK WITH THE ORIGINAL
Open documents in the built-in reader and search their recognized text. Highlight passages, add annotations, and add a signature. Rotate saved PDF and scan pages.

CHOOSE HOW TO UNDERSTAND
• Archive only: Save, read, and find documents without using AI.
• On-device analysis: Get categorization, free short summaries, and key information directly on your device.
• Pro analysis: Get more detailed explanations, context, and possible next steps.

Depending on the document and the analysis you choose, results may highlight deadlines, amounts, tasks, and important conditions. Add recognized appointments to your calendar and open addresses in Maps.

PRO WHEN YOU NEED IT
Each Pro analysis uses one credit. Buy additional credits as one-time in-app purchases. Your first installation includes three trial credits, provided once, for three Pro analyses. Your free archive remains usable without credits.

YOUR DOCUMENTS, YOUR CONTROL
Your archive is stored on your device. Optionally sync it through iCloud across your own devices using the same account. Protect access with Face ID, and use export and import to back up or transfer your collection. No ads or trackers.

Text recognition and on-device analysis run on your device. For Pro, recognized document text is sent through our server to your chosen AI provider. Original files, PDFs, photos, and scans are not sent to these AI providers.
