UPDF AI FAQs

There are several reasons why you cannot find the AI Assistant Icon. Here are all of them.

• 1. You may not know where the AI Assistant icon is. You can follow these steps to find the icon: open one PDF file on UPDF, then navigate to the right bottom menu, and click on the AI Assistant icon to open it.
• 2. If you have UPDF in the old version: older than 1.6.3 for Mac and 1.6.5 for Windows, you cannot find the AI Assistant icon. If you are in the old versions, you can click "Help" > "Check for Updates" to update your UPDF to get the AI Assistant features.

If you're using the AI Assistant within the UPDF app, you can't directly upload a new PDF in Ask PDF mode—it only analyzes the currently open PDF. To switch PDFs, close the current one, open the new PDF, then click the "AI Assistant" icon, select "Ask PDF," and click "Get Started" to upload and analyze it.
However, for the online version, you can upload another PDF directly by clicking the "+" icon in the top-left corner.

AI Assistant is not included in the UPDF Pro Plan. That is why you are in the free trial version of AI Assistant when you already have UPDF Pro. If you need to use AI Assistant Pro, you need to upgrade to AI Assistant Pro.

If you buy a perpetual UPDF and the AI Assistant Pro with an Annual plan, you will be charged annually for AI Assistant.

If you want to cancel your AI Assistant subscription, you need to log in UPDF account, then, find the "Cancel Subscription" button in the "Subscriptions" part, and click on it to cancel.

Chat mode allows you to ask anything, while Ask PDF only answers the questions about the PDF you uploaded.

If you are using AI Assistant free trial version, you can only upload 5 PDF files in Ask PDF mode. And the PDF file size is limited to 10MB for each one and each PDF can have at most 100 pages. And when you communicate with AI Assistant, you can only send 100 messages.

Upgrading to the paid version of UPDF AI Assistant offers the following benefits: upload unlimited PDF files per month, support for PDFs up to 2GB and unlimited pages each, and send unlimited messages for communication.

No, you don't need to purchase the AI Assistant separately for each platform. Buy it once and use it on multiple platforms (Windows, Mac, iPhone, iPad, Android, and web) with a single account. The AI benefits apply across all five platforms, so any remaining benefits from your plan can be used on other devices.

If your storage is full, you can delete some files from the UPDF Cloud to upload more PDF files again.

The UPDF app is downloadable software that provides a range of PDF editing tools and integrated AI features. In contrast, the AI Assistant Online offers AI functionality accessible through a browser without requiring installation, with a focus on tasks such as summarizing and translating PDF content.
Both versions share the AI benefits in one UPDF account. For example, if you have got the free trial of AI Assistant and have uploaded one PDF to it for analysis within the app, then you are only allowed to upload four more PDF files in the web version, as the total free uploads allowed are three.

Compared to other AI PDF tools like Adobe Acrobat, UPDF stands out due to several key advantages:

• 1. UPDF's integrated AI assistant handles larger files and more pages. Adobe Acrobat AI can only work with up to 25MB and 120 pages. UPDF's AI assistant can handle 100MB-2GB and 100-unlimited pages per PDF, depending on the plan.
• 2. It supports analyzing scanned PDF documents. Simply follow the prompt to perform the OCR process first.
• 3. Analyzes and translates documents in almost all languages in the world, unlike Adobe Acrobat AI which only supports English.

Compared to other PDF chatting tools like ChatPDF, there are several significant benefits to using UPDF's AI assistant:

• 1. The AI Assistant tool has two modes: Ask PDF and Chat. Users can ask questions related to the content of their PDFs. They can also chat with AI on topics beyond the scope of the PDFs.
• 2. Supports summarizing and translating PDFs by pages.
• 3. Supports direct summarization and translation of selected PDF content.
• 4. Generates summaries in clear bullet points.

The AI assistant of UPDF is powered by GPT-4 technology, with summarization features using GPT-4o. We continually update it for maximum usability and accuracy. Future updates may integrate GPT-4o technology into all features of UPDF's AI assistant.
