4.5/5

Best For

Researchers, students, and professionals who need fast, accurate answers with verifiable sources, not just raw links.

Key Features

✓
AI-Powered Search with Citations
I tested this daily. It delivers concise, conversational answers with inline citations you can click to verify the source instantly. This is its killer feature.
✓
Copilot (Guided Search)
In my experience, turning this on refines vague queries. It asks clarifying questions, leading to dramatically more relevant and comprehensive answers.
✓
Focus Filters
You can restrict searches to academic papers, YouTube, Reddit, or general web. I use 'Academic' constantly for research, filtering out SEO junk.
✓
File Upload & Analysis
Upload PDFs, images, or text files. I've analyzed research papers and screenshots of code. It summarizes and answers questions based on the content.
✓
Threaded Conversations
Follow-up questions stay in context. What surprised me was its ability to reference sources from earlier in the thread, maintaining a research trail.
✓
Pro Search (Pro Feature)
Uses more powerful models (GPT-4, Claude 3, etc.) with higher rate limits. For complex analysis, I find its outputs are more nuanced and reliable.
✓
Mobile Apps
The iOS app is fantastic. I use it for on-the-go queries. The voice search is accurate, and it feels faster than opening a browser.
✓
Discover/Collections
A feed of trending queries and user-created collections on topics. I find it great for inspiration, but the real value is in your own saved threads.
✓
Library
Saves your entire search history and threads. I rely on this to revisit past research. It's searchable, which is a lifesaver.
✓
Writing Mode
Switches from Q&A to a drafting assistant. I use it to brainstorm outlines or refine paragraphs, though it's not a full-fledged writing tool.
✓
Code Execution (Pro/Experimental)
Can run Python code in a sandbox for calculations or data analysis. I tested it for quick stats; it's powerful but requires precise prompts.
✓
Shareable Threads
You can generate a public link for any conversation. I share these with colleagues to show my research process, sources and all.

Tips & Tricks

TIP

Always enable Copilot for complex or exploratory questions. The extra 20 seconds of clarification saves minutes of manual filtering.

TIP

Use the 'Academic' or 'YouTube' focus filters first. They cut through commercial noise and surface expert or video-based answers directly.

TIP

Upload a PDF and ask it to 'find contradictions' or 'summarize for a beginner.' This extracts incredible value from dense documents.

TIP

When you get a great answer, immediately save it to your Library. Your future self will thank you when you need that source again.

TIP

For Pro users, experiment with model selection in settings. I use Claude 3 for nuanced reasoning and GPT-4 for coding-related queries.

Limitations

-It can still occasionally 'hallucinate' or misrepresent a source, so I always spot-check critical citations.
-The free plan's 5 daily Copilot searches feel restrictive for serious research days.
-It's not a document creator. Its writing aids are basic compared to dedicated tools like Claude or Notion AI.

Frequently Asked Questions

Is the free plan good enough for a college student?+

Absolutely. I tested it for a semester's worth of research. The 5 daily Copilot searches and unlimited standard searches with citations cover most needs. Upload lecture slides or papers for analysis. Upgrade only if you hit the Copilot limit daily.

How accurate are the citations? Can I trust them?+

In my experience, they are highly accurate for direct quotes or specific facts. However, I've seen it occasionally cite a correct source but misinterpret its conclusion. My rule: for critical work, open the top 2-3 cited links to verify context. It's a guide, not a gospel.

What's the biggest advantage over just using Google?+

Time. Google gives you 10 blue links to decipher. Perplexity gives you a synthesized, sourced answer. I tested side-by-side for 'latest treatments for condition X.' Perplexity gave a concise summary with study links in 30 seconds. Google took 5 minutes of clicking and skimming.

Can I use it for coding help?+

Yes, but with a caveat. For explaining concepts or generating snippets, it's excellent, especially with cited documentation. For debugging complex projects, I still prefer ChatGPT or Cursor. Its Pro code execution is neat for data tasks but not a full IDE.

Should I upgrade to Pro?+

Only if the free plan bottlenecks you. If you use Copilot more than 5 times a day, need unlimited file uploads, or want access to the strongest models (Claude 3, GPT-4) for every query, then yes. For casual use, the free tier is remarkably powerful.
