Part 3. Beyond Writing: Introducing UPDF AI as a More Versatile AI Assistant

While the Compose AI extension supports and provides enhancements in your writing speed, it lacks various other advanced features. That is why, if you want an all-in-one AI tool, try UPDF AI.

What is UPDF AI?

It is an all-in-one AI chat bot for chatting with your PDFs, images, and any other topics. Besides the lackluster Compose AI, UPDF AI does not disappoint and offers a wide range of features that enhance your workflow. Read through the following extended features of this AI assistance:

Features

• Summarize Documents: It summarizes PDFs up to 1000 pages, with selective words and lines in seconds. Users can manually select the line within the PDF and pick the summarizer tool from the popup or paste the text in the AI Ask textbox.

• Translate: With no language barrier, use the translate feature to generate accurate translations in 27 languages. Translate selective pages of a PDF or let AI translate directly from a page since it understands almost all languages. Moreover, you can translate the entire document while retaining its original layout.

• Analyze Files: Offering you the facility to stop the command when needed, UPDF analyzes your text once given detailed prompt. After extracting the information, you can either regenerate, summarize, translate, or copy to paste it somewhere.

• Convert Files to Mind Maps: If the written content seems too complex, convert it into a mind map with AI. Choose the language and number of pages to convert into a downloadable mind map.

Despite all these features, you get 100 prompts and 5 file analyses for free. However, upgrading to the Paid version can unlock unlimited features. This AI assistant has been integrated into the UPDF app -  an all-in-one PDF editor for managing PDFs, so, you can download it by clicking the button below if you want an AI with more features.

Conclusion

The Compose AI extension proves to be a smart, lightweight solution for users who need quick, on-the-go writing assistance. Its autocomplete, tone adjustment, and email drafting features make it ideal for professionals. However, for users looking for a more comprehensive all-in-one platform that goes beyond just writing and offering advanced document processing, UPDF stands out as a powerful alternative. Not only that, but it also offers multiple formats and broader AI functionalities.
