What's great

easy to use (7)fast performance (13)user-friendly interface (10)mobile app (3)AI-powered search (20)time-saving (4)clean interface (2)source transparency (9)deep research capabilities (10)

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.

What needs improvement

As a heavy user, I've noticed a few pain points. First, the recent change in how the tool handles full dialogue history seems to have slightly degraded the quality of responses in long threads. Second, when a conversation gets too long, I wish it would automatically summarize or carry the context over instead of just suggesting a new start. Lastly, I've seen some older Spaces stop working properly, which is a shame since they are great for organization. Fixing long-thread context management would make this tool perfect.

vs Alternatives

I chose Perplexity because I need an aggregator of intelligence, not just a chatbot. While ChatGPT and Claude are great, Perplexity gives me the best of all worlds in one interface. The transparency of citations is critical for my research, and the Deep Research mode performs better than any manual search I could do. I also love the direction the team is taking with products like the Comet browser (worthy tool!).

What's great

AI-powered search (20)accurate results (9)search engine alternative (17)

For almost two years, Perplexity wasn't just a search tool, it was the first app I opened every morning on my iPhone. I used it for everything: running advice tailored to my age, diet recommendations, shopping decisions at Watsons, even how to respond to certain messages. I'd screenshot a conversation and upload it, and the response was always sharp, contextual, and genuinely useful.

What made it special wasn't just the search quality, it was the feeling that it actually understood me. It made searching feel like talking to someone informed and reliable, not just querying a database. For a long time, I preferred it over ChatGPT without hesitation.

What needs improvement

limited models (2)hallucinations (6)

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.

vs Alternatives

ChatGPT by OpenAI

Claude by Anthropic

I used Perplexity over ChatGPT for nearly two years because the search quality and contextual understanding felt superior. Perplexity felt more like a research companion, it would go and find things, then tell you what to do with the information.

ChatGPT felt more like a text generator. That gap has narrowed significantly now that Perplexity's quality has dropped.

What's great

fast performance (13)user-friendly interface (10)AI-powered search (20)accurate results (9)citations (16)deep research capabilities (10)

Been using this for quick research and it feels faster than traditional search.

What stands out:
• Answers with sources
• Clean minimal interface
• Good for quick learning

Still testing deeper features but so far it’s really useful for everyday questions.

What needs improvement

deep research capabilities (2)occasional incorrect answers (5)hallucinations (6)

I usually compare tools like ChatGPT or traditional Google search when researching topics.

Perplexity stands out because it combines AI answers with source citations, which makes the information easier to verify. Instead of browsing multiple websites, it often summarizes everything in one response while still linking to the original sources.

vs Alternatives

ChatGPT by OpenAI

Been using this for quick research and it feels faster than traditional search engines.

What stands out:
• Answers usually come with sources, which makes it easier to verify information
• The interface is very clean and minimal
• Responses are fast compared to most AI search tools

It’s been really useful for quick research, learning new topics, and getting summarized information without opening dozens of tabs.
