Oh really, then you should check first whether your own M365 account already includes it.

對，這是這一組最該先做的事，做完再談要不要買Grok。搞不好你要的東西已經在手上了。
So the conclusion is
First check whether your Microsoft 365 account already includes Copilot (US$0) — a lot of people already have it and don't know. Once confirmed, then decide whether you still need Grok (starting at US$10).

They also argued about these things on another page.
The web version offers basic text conversation for free; advanced features such as Copilot Chat, Researcher/Analyst agents, and image generation in Office require Microsoft 365 Premium (US$19.99/month) or an M365 subscription.
The official site publishes no concrete usage figures at all for the free tier, and this site does not fill in an estimate. Verification trail (exhausted): grok.com/pricing returns HTTP 200 but the whole page is rendered by JavaScript, so the static HTML contains no plan names or price text, only Stripe price IDs; opening it in a real browser hits a Cloudflare human-verification wall, which we do not bypass; x.ai/grok returned 403 three times in a row (blocked, not 404). What can be confirmed: free use does exist and is US$0, because in the in-app purchase list on the official Apple App Store listing every paid item belongs to the SuperGrok range, so basic chat requires no payment. Third-party felloai.com states plainly that xAI has never published free-tier numbers anywhere, and says the free tier only gets the lighter Grok 4 Mini, includes basic real-time web and X search, has limited voice mode, and that image and video generation were removed from the free tier on 2026-03-19. The widely circulated figure of about 10 messages every 2 hours has no official backing and is not used here. (Verified 2026-08-09)
