Grok is xAI's AI assistant, with live access to the web and to posts on X. It's for founders who want to know what people are saying right now, about a trend, a competitor or a launch, as well as everyday chat. It's free to try on the web and in the iOS and Android apps. On xAI's pricing page, the Free plan includes limited chat and limited image generation, but not video. Paid plans start with Plus at $8 a month. Premium, at $30 a month, has four times Plus's usage, the latest Grok models and video generation, and Super ($100) and Ultra ($200) raise usage further. The Grok page itself still offers an upgrade called SuperGrok, for higher limits and multi-agent reasoning, but doesn't show its price.
What it can do for you
Ask what's being said on X about your product category this week, get a quick summary of a breaking story, or generate an image for a post (or a short video, on Premium and above). Voice chat is handy for thinking out loud. The live X search is the thing no other mainstream assistant offers in the same way.
What people like
Real-time awareness is the draw: answers that reflect what's happening today, including on X. People also like having image and video generation in the same app.
The honest downsides
- Free limits are tight and shifting. xAI doesn't publish a fixed free quota. Reddit threads describe reduced limits, waits after a handful of messages and features restricted on many free accounts.
- Quality complaints. Some Reddit users say answers got weaker after model changes, and describe overly agreeable writing.
- X is not the world. Social posts are fast but often wrong; treat X-based answers as a pulse check, not facts.
- Video and the newest models cost more. Video generation isn't on Free or Plus; it starts with Premium at $30 a month. The Grok page's "SuperGrok" upgrade doesn't match the plan names on xAI's pricing page, so check which plan you're buying.
Skip it if
- you want a dependable free assistant for long working sessions
- you don't care about what's happening on X
Alternatives
- Better pick for everyday free use: ChatGPT. OpenAI's free plan gives unlimited everyday text chats, so you're far less likely to be cut off mid-task. Use Grok alongside it when you need live X search.
- Perplexity if you want cited answers from the web.
