Grok
“A chatbot strong at real-time search” — the plugged-in colleague who hears breaking news first
What is Grok?
Grok is a conversational AI from xAI that scans X (formerly Twitter) and the web directly, pulling the latest news and reactions into its answers. The same app can also generate images and video.

What sets it apart
These are the differences we found by running the same material through several tools in our training sessions.
See what was just posted
The official app description says Grok has direct access to X and the web to bring you the latest news, trends, and conversations. Because it picks up reactions before they become news articles, it is useful for quickly checking what is being said in your industry.
Ask and create in one app
The official app description lists Grok Imagine alongside chat, deep research, and coding help. You can generate images from text or by voice, and remove objects or change backgrounds in existing photos, all on the same screen.
Start free with the app
According to the official Apple App Store listing, the app itself is free to download and use, and additional features are unlocked through in-app purchases. Korean is among the supported languages, so you can chat in Korean without any extra setup.
⚖️ The weaknesses are clear, too
Because it pulls in public opinion and reactions as they are, the basis is often just a single post. Click through to the original before using anything in a report. In 2026, regulators in the UK, Europe and Canada were also reported to have opened investigations or issued violation findings over its image generation feature.
💡 In plain EnglishLike a well-connected colleague with great sources: they hear things before anyone else, but sometimes repeat them word for word, so you need to check.
There are clearly times when you need to scan real-time opinion and reactions fast. For the same reason, though, the evidence can be thin, so it is safer for an organization to decide in advance what it will treat as a reference and what it will verify.
Same job, different approach
This morning, a story about our industry is circulating online
The old way
- You search portal news, but there is no article yet
- Visit community and social accounts one by one
- Can’t trace where a rumor started
- Say “we’re looking into it” in the afternoon meeting
With Grok
- Ask what the story is and when it started circulating
- Pull in the most widely shared posts and the reactions to them
- Click through to the original posts to separate fact from rumor
- Report what is confirmed and what is not, separately
Common uses
Scan public sentiment quickly
Check what is being said right now about your company, competitors, and industry. Always verify what you get against the original sources.
Catch signals before they become news
See reactions before they become formal news coverage. Use it only to judge whether an issue needs a response.
Light image work
Image and photo cleanup for internal sharing is handled in the same app. Anything published externally needs a separate review.
Who it’s for
Best for
- ✓PR and marketing managers who need to scan online opinion quickly
- ✓Planners who want early signals before they reach the news
- ✓People who actually use X (formerly Twitter)
Better served by other tools
- –Reports and regulatory work where source authority matters
- –Anyone who creates images for external use under the company name
- –Organizations that can only use tools that have passed a security review
Can we use it at work?
The questions that adoption leads and security teams ask first.
Note: The pricing and terms pages on x.ai and grok.com would not open during this check, so we could not confirm from official documentation how X Premium subscriptions relate to Grok usage limits, the data training policy, or enterprise plans.

Using it with other tools
Linking two or three tools changes your work more than any single tool does.

Before you start
- Don’t rely on a single post. Click through to the original and verify it before putting it in a report.
- Don’t experiment while logged in with your company’s official account. Your account is linked to X.
- Have a separate review done before you publish generated images under your company name.
- Don’t enter customer information or unreleased materials until you have reviewed the data training policy.

Checked 21 Sep 2026 · The pricing pages at x.ai and grok.com would not open during this check, so we copied the Korean won in-app purchase amounts shown in the Apple App Store listing for the official xAI Grok app (seller X Corp.).

Where Grok falls short
We don’t just list the positives. Here is what fell short when we used it.
- The pricing is hard to follow
Because pricing is shown as a list of in-app purchases, it is hard to tell what is a monthly charge and what is a one-time top-up. It is also hard to know how much you can use per day for free.
- You’ll need to rework the tone
Answers tend to be casual and mix in jokes, so they are hard to paste straight into a report. You will always need one more step: asking it to rewrite in a formal tone.
- It’s tied to X, which is a hassle
Because your account is linked to X, a timeline and notifications come along even if you only want to use it for work. If you don’t use X, you have one extra step before you can start: signing up.
