Perplexity AI features

Perplexity AI is built for deep thinkers, curious minds, and anyone tired of surface-level search results.

From academic research to creative exploration, here are the key features that make it happen.

Feature #1: Deep research mode

This is the crown jewel. Perplexity’s Deep Research mode runs multiple simultaneous web searches, pulls comprehensive insights from across the web, and stitches together detailed reports. It makes researching faster and much easier for everyone.

It’s ideal for policy analysis, academic research, and complex topics like AI ethics or quantum computing.

Feature #2: Source transparency

You’ll never have to wonder, “Where did this come from?” Source references back every response—be it scientific journals, government sites, or major publications.

That’s a game-changer for professionals in healthcare systems, customer support systems, and academic fields, where verified data matters.

Feature #3: Multimodal capabilities

Perplexity supports text, image, PDF, and even audio inputs, allowing users to upload files or ask questions in various formats. It also lets you export the generated data in different formats.

This makes it super useful for creative tasks, data synthesis, or even reviewing user feedback or business reports by uploading a PDF. It’s all about boosting user interaction and contextual understanding.

Feature #4: Advanced AI models

If you upgrade to Perplexity Pro, you unlock GPT-4o, Claude 3. 5 Sonnet, and Sonar Large—each built for in-depth information, real-time data, and advanced reasoning.

It’s perfect for those working on AI project management tools, market research, or complex tasks like statistical data analysis.

Perplexity AI is your research assistant, deep search partner, and sometimes, creative wingman. Whether you’re exploring AI writing tools, digging through multiple sources, or trying to optimize tasks in seconds, it’s designed to slot right into your existing workflows.

What Is Grok AI?

Grok AI is a next-gen generative AI assistant built by xAI. It is designed to give you real-time, unfiltered answers with a healthy dose of wit and brainpower.

Unlike your average chatbot, Grok doesn’t just respond—it reasons, researches, summarizes, and even helps you code.

Whether you’re an analyst, developer, or just someone who prefers truth with a little sarcasm, Grok brings powerful use of AI tools to your fingertips. It also offers real-time awareness to enhance your experience.

Grok AI features

Grok AI boasts an impressive suite of features that make it stand out in the world of generative AI. Here’s how.

Feature #1: Deep research

Need to dive deep into a topic? Grok’s DeepSearch scans across X (formerly Twitter) and the broader web to dig out niche insights, summarize findings, and transparently show its reasoning—perfect for everything from policy analysis to trend breakdowns. Plus, it links the sources, too!

DeeperSearch (launched in March 2025) takes it further with an even more in-depth experience. It offers extended search and deeper reasoning by analyzing broader data sets, providing you with longer and more detailed answers.

Plus, it remembers past conversations, giving you more personalized, context-rich responses.

Pair it with Big Brain Mode (yes, it’s really called that, and it delivers!), which brings logical flow and advanced reasoning to tackle complex queries with impressive clarity.

This mode allocates additional computational power and is particularly useful for addressing questions in fields like quantum computing, economics, or philosophy. In these areas, straightforward factual answers may not suffice.

Feature #2: Coding assistance

Developers, meet your brainstorming buddy. Grok helps you generate clean code snippets, guides you through best practices, and explains concepts—whether you’re tinkering in Python or working on a React project. It won’t debug, but it helps get unstuck fast.

Feature #3: Image generation

Grok transforms text into stunning visual realities using its advanced image-generation capabilities. From abstract art to realistic depictions of people or landscapes, users can create images like ‘a cyberpunk-inspired city at night’ or ‘a river otter playing the ukulele. ’

Feature #4: Real-time search integration

What sets Grok apart? It taps directly into X’s live pulse— over 580 million monthly active users —to bring you real-time news, hot takes, and emerging trends. Unlike general web crawlers, it can smartly choose to search public posts on X or scan the wider web in real time, depending on what you need.

It’s ideal for journalists, marketers, and anyone who wants to stay current on the latest news or controversial opinions.

Feature #5: Advanced reasoning models

Built on Grok-3, Grok uses reinforcement learning and massive context windows to understand long-form content and multi-part questions.

The Think Mode connects the dots across complex ideas, making it a solid companion for academic research, strategy, or big-picture thinking.

Grok AI: Grok’s DeeperSearch sifts through X and the web for nuanced insights and synthesizes complex topics with narrative depth. However, it can be slower and less structured in citations.

Feature #3: Personality and engagement

Perplexity AI: Professional, factual, and straight to the point. Great when you don’t want fluff.

Grok AI: Injects humor, sarcasm, and even memes when the moment’s right, especially with Persona Mode. It makes learning or browsing less dry and more dynamic.

Feature #5: Cost and accessibility

Perplexity AI: Has a generous free version and a Pro upgrade at $20/month.

Grok AI: While Grok 3 is currently available for free, this is expected to be temporary. Advanced access is available in the X Premium+ plan or can be purchased separately with a SuperGrok subscription ($30–$40/month). This may not appeal to casual users.

Perplexity AI Vs. Grok AI on Reddit

Nothing gives you a better idea of product comparisons than customer reviews, right? Hence, we turned to Reddit to see what users think about the whole Perplexity AI vs. Grok AI comparison.

Here’s what we found.

A user, oplast, on r/perplexity_ai, finds Perplexity’s research capabilities promising.

…I’d describe Perplexity more as an internet search tool with chatbot-like features. In fact, after using it for almost two years, I find it to be the most accurate tool for research, excelling at providing precise, up-to-date, and relevant responses backed by cited sources…

However, another Perplexity AI review by 4sater expressed concern over irregularities in content generation.

The main issue with Perplexity’s Deep Research is the insane hallucination levels. Sometimes an entire report can be hallucinated text with irrelevant links that contain the keywords from your query but don’t actually answer the question or contain the information that Perplexity supposedly “cited” from there.

When it comes to Grok, user Objective-Row-2791 had this to say on r/grok.

I’m having a blast with Grok, seems like their massive GPU investment is paying off. The fact it’s neutral and not censoring much is welcome. Also the responses are very natural.

On the other hand, another user, Istmnck, expressed dissatisfaction with Grok’s pricing.

Pricing is kinda off. $8 premium is useless due to low message limit and $40 premium plus is too much

Yes. ClickUp Brain saves me a ton of back and forth honestly. I know there are AI tools with a pretty efficient free tier, but the constant switching between tabs takes a toll. And honestly, when I’m in my deep work zone, this is the last thing I want to do. I primarily use the AI for writing stuff since I’m in the content industry. It also edits what I’ve written (ah-mazing!). Another thing that really helps me is Docs. I love the formatting options, especially those banners. So cute!

ClickUp’s One Up #2: Turn ideas into action

Does exporting content from AI tools give you a headache, too? Sometimes the file won’t export, or the formatting of the copied content is all off. Well, that’s not the case with ClickUp Docs.

You can create documents containing the generated content right from Brain or use the AI tool inside a document. Create wikis, SOPs, brainstorms, and team notes, then instantly link them to tasks, assign action items, and comment collaboratively in real time.

Create beautiful, searchable hubs for policies, playbooks, and FAQs that everyone can access, edit, and update. Unlike Perplexity and Grok, which help individuals learn, ClickUp helps you retain and scale your collective intelligence.

I like that it will reference your other docs and content, for example, I made a template doc for creative briefs and now when I ask it to write a full brief based on a small paragraph it will write it out in the form of my template, that has been nice.
