What features stood out to me in Perplexity AI?
Within the first month of testing Perplexity AI with my usual research tools, I started noticing features that would explain why my colleague kept talking about it. What began with simple article research soon turned into the discovery of features that genuinely improved my workflow. Here's what impressed me during my testing period:
Claude integration
First, I tried this feature on semiconductor manufacturing research, which I report on quite regularly. In Perplexity AI and my usual tools for research, I typed a request to "explain current semiconductor supply chain issues." The difference was clear. Where others gave me broad overviews, the integration of Perplexity AI's Claude offered insights from recent industry reports, connected these with global trade data, and cited specific company statements from TSMC, Intel, and Samsung.
The real value came when I asked follow-up questions. Without restating the context, I could ask, "What's their solution for this?" and get relevant answers about each company's expansion plans and investment in new manufacturing facilities. Each response included links to official announcements and recent financial reports.
Copilot mode
It soon became the feature I relied on most for hard-core topics. The day my editor asked for an article about quantum computing breakthroughs, I fired up Copilot mode and asked, "What are the latest commercial quantum computing developments?" It naturally led to more profound knowledge regarding various companies' approaches, challenges, and market effects.
For example, IBM's quantum roadmap mentioned bringing the latest technical papers, development timeline, and recent announcements concerning its new processors online without starting another search.
Real-time information processing
Thus, fact-checking required testing its real-time capability. When Microsoft announced updates to its AI tools, I ran parallel searches on Perplexity AI and traditional search engines. Events changed when Perplexity AI pulled quotes from Microsoft's developer blog, tech news sites, and social media announcements just minutes after release. What was different was that it ordered everything chronologically and then underlined what conflicted across sources.
The practical example: A search for "Microsoft Copilot enterprise features" returns the latest pricing changes, compatibility updates, and user reviews, dated and sourced appropriately. It beats scrolling through multiple tabs and cross-referencing dates manually.
Research collections feature
This feature seemed so simple until I started organizing my research related to the tech industry. I created separate collections for AI developments, semiconductor industry news, and renewable energy innovations. Instead of just bookmarking links, Perplexity AI automatically categorized related searches and underlined connections between topics.
For instance, my AI collection automatically connected related searches about the chip requirements for large language models with semiconductor manufacturing capability, allowing me to spot some industry trends I would have missed.
Multi-source verification
When testing this feature, its accuracy stood out. Perplexity AI tabulated automatic data from research papers, company benchmarks, and independent testing when researching one conflicting claim about AI model performance benchmarks. It clearly showed when sources disagreed and highlighted the most recent verified information.
I have extensively tested this, comparing ChatGPT to a tool that pulls performance metrics from official documentation, user reports, and independent evaluations to distinguish what has been marketed and verified.
How did Perplexity AI perform in real-life scenarios
Taking Perplexity AI from mere testing to actual work projects showed its capabilities. Here is what happened when I put it through actual tasks during my testing period.
Technical article research
I had an article about AI chip architecture to show how different companies approach neural processing units. I asked, "Compare current NPU designs from major chip manufacturers." Perplexity AI gathered information from semiconductor industry reports, technical documentation, and recent conference presentations.
What impressed me most was the way it introduced technical content. For example, the in-depth study on NVIDIA Tensor Core architecture analyzed performance metrics from developer documentation and architectural diagrams. Each technical detail references a source from official documentation and recent benchmarking.
Market analysis tasks
My editor assigned me a story about emerging AR/VR markets. I fed in the query, "current AR/VR market share and growth trends." Perplexity AI's newest market data feature compiled information from IDC reports, quarterly earnings calls from industry leaders, and market analyst forecasts.
The real value came in the cross-referencing. When Meta announced new VR features, Perplexity AI immediately tied this together with predictions of market impact and responses by competitors such as Apple and Sony.
Academic research support
I tested this feature while creating a research paper on renewable energy storage, and it was competent. I needed to find recent breakthroughs in solid-state batteries. Perplexity AI found relevant papers, sorted them by the researchers' institutions, and highlighted key findings.
Fact-checking breaking news
It was interesting to test the accuracy of Perplexity AI with breaking technology news. When NVIDIA recently released its latest line of GPUs, I used it to fact-check many performance claims. It simultaneously pulled test results from tech reviewers, user benchmarks, and official specifications. That helped me catch discrepancies between the marketing claims of performance against real-world no time.
Teaching assistant work
I tried Perplexity AI while preparing materials for a programming course. A search for "latest Python web development frameworks 2025" yielded up-to-date documentation, user reviews, and GitHub statistics. It was good at finding recent code examples and implementation challenges.
Tracking framework updates worked exceptionally well. When Django released a new version, Perplexity AI automatically highlighted breaking changes and new features, saving hours of reviewing documentation.
Content strategy research
Perplexity AI was useful for planning the content. Researching "emerging technology trends in renewable energy" gave a broader view of industry trends, research breakthroughs, and market predictions.
The tool proved its worth by connecting seemingly unrelated trends. It helped me find possible story angles by connecting the dots between advances in battery technology and solar panel efficiency.
Personal project investigation
I also tested it with my tech projects. In researching home automation systems, I wanted details on which protocols support certain features. This AI from Perplexity helped me sift through technical specifications and user experiences on integration possibilities faster than I usually would through standard research.

It remembered previous queries and built on that knowledge, making the research flow natural and efficient.
User-Friendly Interface
Transitioning from complex research tools, I found Perplexity AI's interface refreshingly clean and intuitive. All necessary features are just a click away. The layout is logical: search history occupies the left panel, main results fill the center, and source citations remain visible. There is no endless menu diving or confusing settings to navigate.
Source quality
I'm picky about sources, especially when it comes to technical articles. Perplexity AI consistently pulled information from reputable journals, official documentation, and recognized industry experts. When citing statistics about AI market growth, it provided links to established market research firms and official company reports rather than random blog posts.
Customization options
Perplexity AI saves time by allowing you to set your search preferences. Setting preferred sources, technical depth levels, and industry focus helps filter irrelevant information. This feature is handy when switching between technical documentation and general-audience articles.
Cross-reference capabilities
However, the system's automatic cross-referencing was genuinely remarkable. When searching for AI training expenses, the tool automatically connected information related to hardware requirements, energy consumption, and cloud computing costs, revealing key cost elements I could have never noticed through traditional research.

Cost-effective research
Perplexity AI service had a lot of value to me compared to separately subscribing to different research databases and news sources. Within my first week of testing, the access it gave me to comprehensive, cited information from several premium sources justified the cost of the subscription.
What didn’t work well with some tools?
Despite these impressive features, a month of testing revealed some fundamental limitations and frustrations. Here's what to know before committing to Perplexity AI.
Information overload issues
Sometimes, it's too informative. For example, a search for "latest developments in quantum computing" yielded extremely long results. Comprehensive, yes, but wading through many research papers, news articles, and technical specifications was quite a chore. A better filtering system would manage this information flood.
Technical glitches
The system periodically paused during extensive research sessions. In fact, after an hour of continuous use researching the manufacturing processes of semiconductors, noticeable increases in response times began to manifest. I had to refresh the page frequently to restore its normal speed, which was frustrating on time-sensitive projects.
Pricing structure limitations
Its limitations as a free version showed up rather quickly. When I reached the daily query limit, I used it to research AI training methodologies. It went from getting detailed responses to essential information, which was pretty jarring. The Pro version solves this, but at $20 per month, that might be steep for casual users.
Source verification challenges
Not every source is equal. In my research of emerging tech startups, I found that some had outdated information interspersed with current information. Sometimes, the tool does not separate primary and secondary sources, which entails additional verification time.
Learning curve
Mastery of advanced features takes time. Advanced features such as custom collections and advanced filters were not intuitive. It took me about a week to fully understand how to structure the queries for optimal results. The tutorial system needs improvement.
Mobile app limitations
While the mobile iteration works, it has its own kinks. During conference coverage, I noticed that the app was a battery guzzler. Its image analysis sometimes couldn't process complex technical diagrams well enough, so I switched to a desktop. It is okay for quick searches but not for heavy, serious research sessions.
Language processing gaps
Sometimes, this system was puzzled over technical terminologies. When searching within certain programming frameworks, it frequently confuses terms of similarity. An example would be where the search term is "React Native performance optimization" but pulls information related to general React.js. Usually, the workaround for this included rewriting queries to particular phrasing to bring the desired correct response.
Integration restrictions
Although it has some browser extensions, it lacks integration with standard research tools and does not have direct export to reference management software such as Zotero or Mendeley. I had to copy and format citations by hand, which was time-consuming for larger projects.
Update inconsistencies
Real-time information isn't always real-time. I've seen delays from official announcements to database updates within Perplexity AI while working on breaking tech news. Sometimes, I wait 30-60 minutes for the latest information to surface in the search results, which isn't the ideal setup for timely reporting.
Search history organization
The search history is a letdown. It's unusable after many hours of research, and finding earlier queries can be challenging. Currently, the system does not offer suitable filtering and categorization options. I often had to scroll through dozens of searches manually to find the earlier points of my research.
