A Comprehensive Review of Petal AI & Its Better Alternative

Generative AI tools are becoming a new norm with every passing day. Today, there are plenty of AI assistant tools that make it easy to consume complex content, such as research papers, user manuals, and others. Petal AI is one such AI document analysis platform that provides a wide range of features to assist in document reading and analysis with AI assistance. Therefore, this guide is going to conduct a comprehensive Petal AI review, including its performance analysis, user reviews, and pros/cons. The guide also presents its better alternative, the UPDF AI, at the end. So, let's begin our discussion.

Part 1. Petal AI – A Complete Overview

Before we head for a thorough performance analysis of Petal AI, it's important to understand its basics.

1.1 What Is Petal AI? What Is It Used For?

Petal AI is a web-based document analysis platform that provides an AI chat box to ask document-related questions. It allows us to upload any type of document and then begin chatting with the document. It even allows annotating text, adding comments, and sharing the file with others through a shareable link.

It also provides a central cloud space to manage all documents. Besides that, its "AI Table" feature allows us to ask a similar question from multiple documents at once. In short, Petal AI is a virtual AI assistant for interacting with documents deeply and understanding complex concepts easily.

Although the Petal AI chat box is easy to use, its 400-character limit per query can hinder its functionality. The chat box should have a large character limit so that we can type lengthy queries. In contrast, UPDF AI, another document analysis platform, not only provides a powerful AI assistant to chat with documents but also provides a larger character limit per query. Besides that, it offers a more intuitive way to interact with documents. So, if you want a more robust experience, try out UPDF AI instead.

1.2 Is Petal AI Free? Does It Have a Monthly Fee?

Petal AI is not entirely free. In its free plan, you get only 40 credits to use its AI assistant and 1 GB of cloud storage. Other than the free plan, it has multiple monthly fee plans. The image below provides all its pricing plan details:

You can choose between its pricing plans based on how many credits you need for document analysis.

1.3 How Does Petal AI Work?

Being a web-based tool, Petal AI provides an instant way to upload your documents directly from your system or through the cloud. Once the documents are uploaded, you can access them individually and use its AI chat box to interact with documents.

To better understand the performance and efficiency of Petal AI, we will ask Petal AI to perform various tasks and then evaluate its responses to make a conclusive decision on its effectiveness. We will use a technical research paper published in IEEE Xplore about AI techniques for detecting COVID-19.

Petal AI first asked us to create an account before assessing any of its functionality. Once done, we were provided multiple ways to upload our documents.

After uploading the document, it automatically provided us with a very brief summary of the document. However, the text in the summary wasn't good quality-wise and also had grammatical mistakes.

Afterward, we opened the research paper document to ask deeper questions with Petal AI. We first asked it to summarize the research paper to get a more authentic summary. It instantly gave us a brief summary highlighting the research's key points.

Honestly, we were expecting a more detailed summary. So, we decided to ask it to provide a more detailed summary. This time, it provided us with a more detailed summary. However, it took two credits to provide the lengthy summary. It means that the credits can drain quickly for lengthy text requests.

Next, we asked it to explain "how COVID-19 is diagnosed through blood test report". It analyzed the document content and then provided us with the relevant information. So, it works pretty well in terms of explaining concepts.

Now, we decided to test its capabilities in explaining graphical content in the document. So, we asked it to explain figure 2 "SVM Illustration". However, it failed to detect the figure and was unable to answer.

In contrast, UPDF AI is another similar AI assistant to chat with documents, but it was able to respond to our same graphical content explanation query effectively. Try out UPDF AI and test its advanced AI analysis capabilities yourself.

Lastly, we decided to see if it's able to answer questions outside the scope of the document. So, we asked it to tell "When was COVID-19 originated". Although this information was not present in the document, it was still able to provide an accurate response.

Overall, we can say that Petal AI is a powerful document AI assistant tool that can help us chat with documents and consume complex topics effectively. However, its limited credits and occasional failure to respond can hinder its usage potential.

1.4 User Reviews and Pros & Cons

If we look for Petal reviews on the web, we don't find many user reviews. Even reputed review sites, like TrustPilot, also haven't listed it. And the ones that have listed Petal Org have not received any reviews.

After digging and reviewing the small user review responses available on the web, we found that users liked its document analysis capabilities and assistance with AI-driven features. However, the learning curve and occasional missed/inaccurate responses were some concerns with Petal AI.


  • Context-aware generative AI
  • Support multiple languages
  • Easy file management with a centralized cloud drive
  • Easy collaboration and sharing
  • Chat outside the document scope


  • Learning curve
  • Inaccurate/missed information occasionally
  • Limited credit
  • Costly paid plans

In short, Petal AI presents itself as a handy platform for document analysis with the power of AI. However, it often requires double-checking the information it provides. In contrast, UPDF AI is also a powerful document analysis tool that provides an even more intuitive interface and efficient capabilities at a lower price. The next section talks in detail about UPDF AI.
