“I like how Perplexity makes research faster by combining AI-generated answers with web search and citations. It helps me quickly understand complex topics, verify information, and find useful sources without having to open dozens of websites. Perplexity is very useful for research, but there are a few areas where I think it could improve. During longer research sessions, the interface can start to feel a bit cluttered, which makes it harder to stay focused. I’d also like to see deeper integratio”
“A lot changed around the start of this year, and not for the better. Three specific things broke the experience for me:Upload limits. There is now a cap on how much you can upload, which killed one of my most-used workflows, screenshot and getting contextual responses.AI switching. When Claude usage hits a threshold, Perplexity automatically switches to its own AI model. The quality difference is noticeable and jarring. It no longer feels consistent.Context retention. This was the final straw. When I continue a conversation on the same topic, it no longer holds the context of earlier exchanges. I have to re-explain everything from scratch, which defeats the entire purpose of a conversational search tool.”
“Very clean and easy to work with. The deep research is also pretty fast and accurate. For market research, I don’t want random answers, and Perplexity gives me the source right next to the information so I can open the report, article, or company page and verify it myself. That makes the research much more usable and trustworthy for my needs... When I’m researching industry numbers, I still have to check original sources since different reports often use completely different definitions. Perplex”
“It saves me a lot of research browsing before I start designing. The AI models sources citations is so necessary for me. If I'm researching a design pattern or looking at how competitors structure something, I can actually open the sources and see where the information came from..The pricing is pretty affordable too. Sometimes the research is still too text-heavy for design work. If I'm researching visual patterns, I want to see more actual interfaces and examples rather than just descriptions o”
“What made me decide to renew my Perplexity Pro subscription after 1 year is that the models I can choose from can be used more freely than, for example, with Gemini directly (much more creative and not with an extreme temperature of .4) – also, my data is not used for training purposes as it is with Gemini Pro. Claude sonnet 4.5 thinking is a great model that allows for much more token consumption than with Claude directly. Perplexity is perfect for everyday use. However, Perplexity alone would ”
“$2,400 a year for this bs no worth it: Not worth it”
“Can’t follow instructions: Can’t follow simple instructions then says you’ve used you freebie and tries to make you pay to finish what it should have done the first pass. Don’t waste your money”
“Review those Terms of Services. They literally own everything you do inside their browser. Don't do any confidential work or any kind of protected work. Yes, it sees whats in your browser; yes they save it and train on it.”

“这期视频介绍了Perplexity Comet实际能提升工作流效率,但隐私问题确实值得警惕。感谢作者的真实体验分享!”
“Perplexity has become my primary OS for information. I use it for hours every day, and it has almost entirely replaced other LLMs for me. It’s a true all-in-one powerhouse: from quick daily chores to deep technical research and multi-page project planning.The UI is a masterclass in "clean focus" I love how it feels both on desktop and mobile. Features like sharing conversation links, seamless voice interaction, and the ability to switch between all top models in one place make it indispensable for my workflow. Even the image generation and file/photo analysis are surprisingly robust. It’s rare to find a tool that handles everything from shopping links to complex document summaries so gracefully.”
“Love Perplexity for Information Suggested Talking Points for Prospects. | I think it's excellent for querying how to approach specific prospects based on the persona I created. | Pros: Research the company that my prospects work for. | Pros: Research background on my prospects. | Pros: Combine those two and come up with about one page on how to approach them based on the space (persona) I created. | Cons: Sometimes navigation is a little tricky. | Cons: I would appreciate a better delineation w”

“It has completely replaced standard Google searching for my day-to-day work. Instead of opening 10 tabs, scanning through fluff, and manually compiling answers, Perplexity gives a synthesized summary with clear footnotes to the original pages right away. The Pro search feature is great when I need a multi-step dive into complex topics, and the Focus modes (like Academic or Writing) help narrow the scope so I don't get irrelevant web clutter. It essentially functions as a hyper-efficient research”
