Product: Adobe Acrobat
Device & OS: not provided
Scenario: Using the AI Assistant feature to analyze, summarize, or chat with a PDF document.

Solution 1Recommended

Re-authenticate and Update the Acrobat App

Session errors or outdated software can cause the AI assistant to hang, especially on mobile devices. Refreshing your login and updating the app often resolves this.

This method refreshes your account's cloud connection and ensures you have the latest bug fixes and security patches from Adobe.

Test with a different PDF

Open a completely different PDF file in Acrobat and test the AI Assistant to determine if the issue is specific to one document.

Sign out and sign back in

On your mobile device or computer, tap your profile icon, sign out of your Adobe account, and then sign back in using the same credentials.

Install available updates

Open the App Store, Google Play Store, or Creative Cloud desktop app. Check for Adobe Acrobat Reader updates and install the latest version.

Restart your device

Restart your phone, tablet, or computer to clear temporary cache files, then open Acrobat and try the AI Assistant again.

Re-authenticate and Update the Acrobat App

Corrupted Chat Sessions: If the issue persists on a specific document, the underlying chat session data may be corrupted. Deleting the chat entirely and creating a new one may help after a restart.

Frequently Asked Questions

Why does the PDF AI Assistant keep saying 'Processing' but never finishes?

This usually happens due to a dropped internet connection, an overly large or complex PDF file, or server-side issues with the AI provider. Restarting the application and checking your network connection are the best first steps.

Can the AI Assistant analyze image-based or scanned PDFs?

Most AI Assistants require text to be selectable. If your PDF is purely scanned images, you must first run an OCR (Optical Character Recognition) tool to convert the images into readable text before the AI can analyze it.

Is there a file size limit for PDF AI analysis?

Yes, PDF AI assistants typically have limits on file size and page count (e.g., maximum 25MB or 120 pages). If your document exceeds these limits, the AI may fail to process it. Try splitting the PDF into smaller sections.
