Using Perplexity's Comet web browser for research is a delight as it saves considerable time over just a search engine. Not only does it make a concise summary, but it also lists all its sources via links. Preplexity's performance as a research/data AI, I think, is excellent. I am using the free version, so the price is right. When I have fact-checked Perplexity's results, it has always been correct. Review collected by and hosted on G2.com.

I do not have a downside or dislike for Perplexity, but I only use it for research, and I use Galaxy.ai for creating images and videos. Review collected by and hosted on G2.com.

I like best about Perplexity is its ability to provide concise, well-referenced answers instantly. It combines the speed of an AI assistant with the reliability of real web sources, making it perfect for quick research or fact-checking. I also appreciate its clean interface and built-in citation system, which makes verifying information effortless. Review collected by and hosted on G2.com.

I dislike about Perplexity is that it sometimes lacks depth or contextual understanding in longer or more complex queries. While it’s great for quick answers, it occasionally gives surface-level explanations or repeats information from sources without deeper analysis. Additionally, customization options and conversation continuity could be improved to make it more flexible for power users. Review collected by and hosted on G2.com.

I’ve had the Pro version for over a year. The responses are very sharp, and honestly, the image editing is better than other AI tools on the market. Review collected by and hosted on G2.com.

Sometimes I used it to review and to confirm answers for exam questions, but the responses were not accurate at all. It failed badly on questions for the final module a CPR course. I know is not meant to be use this way. However, I was looking for a different approach and perplexity didn't fulfill the expectations Review collected by and hosted on G2.com.

Perplexity doesn’t just have one model; it works more like a model aggregator with citations, and it almost feels too good to be true when I’m doing research. The Deep Research and Apps feature (it was Labs at first) are really useful, the UI looks amazing, and the latest computer update is what convinced me to get the Max subscription.

Sometimes the citations aren’t accurate, and since its USP was delivering accurate results, it can end up hallucinating too much. The live data integration also doesn’t make it feel unique anymore. Review collected by and hosted on G2.com.

I like that I can use different AI models from various providers on the same site with a single subscription, which makes it very practical and convenient. Review collected by and hosted on G2.com.

I believe that if you are not attentive to the model you want to use, the system that automatically assigns one to you is usually not very accurate. That's why you have to pay close attention and choose the model you want to use yourself. Review collected by and hosted on G2.com.

What I like best about Perplexity is that it gives fast answers with sources attached, so I can trust what I’m reading and check it myself. It feels like a search engine and an AI assistant working together instead of making me dig through a bunch of tabs. Review collected by and hosted on G2.com.

What I dislike most about Perplexity is that it can still be shallow or repetitive on harder questions, even when the answer looks polished. It’s great for fast research, but you still have to double-check facts because AI tools can make mistakes or oversimplify complex topics. Review collected by and hosted on G2.com.

I really like the new conversational style and how well it remembers context across multiple questions. It’s become much better at structuring long, complex answers into clear sections that I can reuse in my work, and the citations make it easy to double‑check key points when I need to share them with others.

Sometimes the answers can be a bit too detailed when I just need a quick, two‑line summary, so a clearer ‘brief vs deep’ toggle would help. I’d also love even more transparency on which sources are being prioritised in the citations, especially for news or opinion‑heavy topics. Review collected by and hosted on G2.com.

It can be used in browsers across different operating systems as well as on smartphones. The interface is simple and streamlined, and the various options are easy to spot and understand right away. You can use operators to better refine searches (for example, limiting the query to a specific website or to a defined time period), or choose specific scopes (academic, social, web or finance) depending on where you want to look for information. In the results, links to the sources are clearly provided, so you can open and consult them if needed. You can also share search results with other people and decide what type of access they have for viewing. Shortcuts help speed up input and you can create custom ones to handle recurring actions. In the Spaces area, you can organize searches based on your needs by creating folders dedicated to particular topics or projects. Review collected by and hosted on G2.com.

Sometimes it provides incorrect information. Even though it is based on real-time, web-updated sources, I have, for example, come across inaccuracies regarding recent changes in regulations. When I repeated the same search a few days later, or explicitly pointed out that there had been recent updates on the topic, the response I received actually differed from the previous one. For this reason, it’s not appropriate to take everything it says at face value.

More advanced features—such as creating recurring tasks by giving instructions to run certain searches on a defined schedule, choosing which AI model to use, or accessing a dedicated support service—require a Pro subscription.

In the free version, the Spaces area is quite limited, both in the number and types of files you can upload and in the sharing limits with collaborators. Review collected by and hosted on G2.com.

I really like Perplexity’s ability to retrieve data from the web. Since I work in research, it used to take me a lot of time to find information by opening each URL and digging through multiple websites. Perplexity has completely changed that for me. With a single prompt, and even when I use customized prompts or system instructions, it delivers the results I’m looking for.

I’ve been using Perplexity for about a year now, and I still haven’t found another tool that does this as well. I’m also using the Comet browser, which I think is awesome because it can control the browser and complete tasks on its own. For research, having a browser that can do that is genuinely valuable. Review collected by and hosted on G2.com.

Its biggest drawback lies in its strongest feature, it searches the web amazingly well, but while presenting the source URLs, they are often inaccurate. Sometimes the links are broken and lead to “page not found,” or they appear to be hallucinated.

Also, context is lacking in Perplexity. I’ve found that ChatGPT and Claude provide better context, which sometimes makes me unsure about relying on it.

I have also used Perplexity API keys for data retrieval, but I was quite disappointed with its performance. At times, it didn’t return the data I needed; sometimes it hallucinated results, and occasionally there were errors. Review collected by and hosted on G2.com.

I'd say the citations. I can quickly check where an answer came from instead of just trusting the AI. Makes researching stuff way easier, and I end up wasting less time double-checking everything. Review collected by and hosted on G2.com.

Probably the message limit when I'm in the middle of researching something and suddenly I have to wait. Review collected by and hosted on G2.com.
