Frequently asked questions
Can AI document summarizers handle scanned PDFs?
Yes, many modern AI summarizers use optical character recognition to read scanned documents, though tools with multimodal capabilities like ChatGPT and Gemini generally perform better with scanned files.
Are my confidential documents safe when using AI summarizers?
It depends on the platform. Enterprise tools like Microsoft Copilot and paid corporate tiers of ChatGPT and Claude guarantee that your data is not used for training models, whereas free consumer tools may retain data.
What is the difference between a context window and a file size limit?
A file size limit refers to the physical weight of the document in megabytes, while a context window measures the amount of text tokens an AI model can hold in its active memory at one time.
