Both Dropbox Dash and Adobe Acrobat AI Assistant help summarize and organize documents. The AI features in both are very useful, but which is better?
Platform and costs

You can access Adobe Acrobat AI Assistant through the desktop version of Adobe Acrobat, the browser version, and the mobile version (in beta at the time of writing).
You must purchase Acrobat AI Assistant as a separate add-on to your Acrobat package. Any type of plan can use Acrobat AI Assistant, even free plans – but you must purchase AI Assistant to use it. The price is $4.99/month, regardless of which plan you have. This means that even users of Adobe Acrobat Pro – a paid subscription – still need to purchase the AI Assistant add-on separately.
Dropbox Dash is available as a separate app, but is also available through a browser and a mobile version, available only in the United States. You can access Dropbox Dash on both Windows and Mac computers, Apple and Android mobile devices, and all major browsers.
Summary tool

Using both Acrobat AI Assistant or Dropbox Dash to summarize documents is one of the most useful ways to use either tool. While there are other AI tools like Otter to summarize audio material into written summaries – a great AI tool for content writers – AI Assistant and Dash both do a great job of summarizing Long text quickly.
When you open a document with Acrobat AI Assistant, you're immediately provided with a basic overview. You don't need to do anything to get an overview, this gives you an instant document snapshot – and you can upload documents up to 600 pages in size and up to 10 documents at once. for a while.
Dropbox Dash can quickly summarize countless documents. Not just documents and files you've uploaded, but also summaries of work meetings, emails, Notion boards, and many other text-based and text-in-image documents. It summarizes much more than Acrobat can provide, but has a heavier usage system in comparison. You can find a summary by asking questions about the document, file, or connected account.
Search engine

Acrobat AI Assistant offers a variety of search tools, including typing a question or using voice search. The application overview generates general but related questions that you can use as a starting point if you don't have any yet. There is also a text box where you can write your own question.
Dropbox Dash has a universal search function that can scan and search not only your documents but also the files and apps you connect to your account. It can act as a search engine in documents, files and personal accounts, allowing you to save time searching for answers by asking Dash instead.
Voice search

Using Acrobat AI Assistant from your smartphone, you can use voice to search your documents. Acrobat AI Assistant for phones is in beta at the time of writing, so it's not currently 100% effective, but given Adobe's history, good results can be expected when the feature This is completely public.
After using the voice search function, you can play the answer out loud so you can hear it instead of just reading it.
Note: At the time of writing, Dropbox Dash does not have voice functionality or voice search capabilities.
Quote

When using Acrobat AI Assistant to scan through documents, summarize, or answer questions you've asked the AI about your document, the results will always appear with an associated citation. Doing so ensures you can demonstrate where Acrobat AI Assistant found the information it presented to you.
Thanks to the citation, it also proves to you that any information provided comes directly from the information you provide to Adobe Acrobat. It doesn't pull inaccurate or incorrect information from other sources, and you can always go directly back to exactly where it summarizes the information for your peace of mind.
Dash Dropbox also cites its sources, but its citations are not as clear or easy to retrieve as Acrobat's. Because Dash has access to more content and data, due to the integrated apps you can connect to, the possibility of providing misleading information in answers is higher.
Connect to external applications

Acrobat AI Assistant does not connect to other applications outside of the Adobe toolset. While it may sound limited, because it works in Adobe Acrobat, it has a lot of built-in features, so you don't miss out on much by not connecting to external applications.
Adobe Acrobat AI can connect directly to Adobe Express, one of the best Adobe applications today. Through this connection – although slightly different from the Acrobat AI Assistant tool – you can integrate AI-generated images and add designed layouts to your documents. Great!
Dropbox Dash's interface features a control panel that allows you to connect any and almost all management and productivity software tools to Dash. Doing so allows you to use Dash's AI search capabilities across all other apps, including email, chat threads, and calendars, etc.
Tips: The more applications you connect to Dash Admin Console, the more you benefit from using Dash. Dash can provide answers not only from its documents, but also from accounts you've linked by reading messages or other information shared through linked accounts.
Although these two tools offer similar features, they are different enough to have their own place. Adobe Acrobat AI Assistant is the best choice for not being region-blocked for the US.
You can rest assured that Acrobat uses citations; they're clear and transparent, something you won't find in Dropbox Dash's vague quotes. Many people also like the fact that Acrobat has no external application connections. They don't want AI interfering in every step of their lives, and it's annoying to have to launch Dash every time they open their laptop instead of only accessing it when they want or need it.
