5 Favorite AI Tools for Web Research

This updated guide compares favorite AI tools for web research and highlights the details that matter most. Gone are the days when online research was a time-consuming (and frankly, boring) process. Artificial intelligence (AI) is crawling the web for insights, whether you want basic tips or need research for your college thesis.

1. Perplexity

Perplexity is one of the best AI tools if you want software that acts like a search engine. Every time you search for a topic, you get a comprehensive reasoning and a list of sources where the information was extracted. The app then provides a summary of your responses and follow-up questions so you can dig deeper into your research if needed.

While the app's basic tools are some of the best, Perplexity does not stop there. With the Deep Research feature, you'll first get some initial information about your query. Then the app will dig deeper to find all the stats and citations you need. Once you're done, you'll see everything in three tabs:

1. Deep Research
2. Images
3. Sources

In our experience, Perplexity's Deep Research tool is significantly more comprehensive than Copilot and ChatGPT (though It is best to still consider subscribing to Perplexity Pro and ChatGPT Plus ). Overall, Perplexity is so good that it might turn AI skeptics off; Along with browsing articles, you'll also get images and videos related to your search.

Perplexity is available as a web app; the desktop app does not offer any additional benefits, so you'll want to use it in your browser from your computer. You can download the app on iOS and Android.

2. ChatGPT Deep Research

You can use ChatGPT Deep Research in a variety of ways, such as exploring statistics and sourcing for your larger research projects. it is a great companion for students, academics, and you'll find similar uses if you're looking to do research for your work. At the time of writing in April 2025, the software is available to ChatGPT Plus and PRO users.

While searching the web, ChatGPT provides live updates. You'll see what the software has found throughout the research process, giving you a better overall picture. This is especially helpful considering that ChatGPT usually takes at least 3-5 minutes to collect research and put it all together in the app.

Once you've compiled your research, ChatGPT's Deep Research tool gives you a full breakdown. You'll see the sources used for each point, allowing you to choose through and research further if needed. You'll get access to a limited number of Deep Research credits each month if you have a premium subscription.

3. Microsoft Copy

While Copilot's Deep Research tool isn't on the same level as ChatGPT or Perplexity, the basic version can compete with them. Copilot is great at visualizing data and making it easier to understand. for instance, its mind map graphics tend to be less glitchy than ChatGPT's.

Copilot is great for creating tables. You can use this to compare different products you might want to buy, and it is also useful for highlighting key statistics or talking points from your research projects.

To use Copilot, you can sign in with your personal Microsoft or GitHub account. The basic version is free, but you can subscribe for $20/month. You can try it for free for 30 days before paying a monthly fee.
