[Review] Grok Pricing: The Official Page Loads Fine, But Every Number Is Hidden

Grok is the X (formerly Twitter)-integrated chatbot built by xAI, sold on real-time information and a blunter, less filtered tone than most chatbots. We went looking for a straight answer on Grok pricing and its free tier limits, and ran into something unusual: the official pricing page works, but it won’t tell you anything.

This piece is a review of what we actually found when we checked, not a restatement of xAI’s marketing. Three checks, three dead ends on the official channel — and the numbers we do have came from somewhere else entirely.

The pricing page that shows nothing

Here’s the part that will frustrate anyone trying to research Grok pricing before signing up. grok.com/pricing returns a normal HTTP 200 response — the page is live, not broken. But the static HTML behind that response contains no plan names and no prices. What’s actually there is a set of Stripe billing codes (the payment processor’s internal labels), not consumer-facing text. The real pricing text only gets built in the browser by JavaScript, and when a browser actually tries to load it, Cloudflare’s bot-check screen gets in the way. We don’t bypass verification walls, so that route stayed closed.

Illustration: Official pricing remains hidden behind empty dynamic pages, verification hurdles, and blocked doorways that prevent price checks.

We then tried x.ai/grok, a second official domain that sometimes carries pricing info for xAI products. Three separate attempts, three 403 responses — “forbidden,” meaning the server actively blocked the request, which is a different situation from a page simply not existing (a 404). xAI’s own channels, in other words, were reachable but unreadable, twice over, on the same day.

Where the real numbers came from

Since grok.com and x.ai wouldn’t surface prices directly, the only working source was Apple’s App Store listing for Grok, where in-app purchases are legally required to be spelled out in plain numbers. That listing shows four paid tiers: SuperGrok Lite at US$10/month, SuperGrok at US$30/month, SuperGrok Plus at US$100/month, and SuperGrok Heavy at US$300/month. A third-party tracking site, felloai.com, independently lists the US$30/month SuperGrok price too, which lines up. The App Store listing also shows an annual option on the SuperGrok tier at US$300/year — worth noting separately from the US$300/month Heavy price, since those two numbers look identical but describe completely different billing periods.

A free tier that exists, but isn’t measured anywhere official

The good news: Grok’s free tier is real, and it’s genuinely free — not a trial. The App Store’s purchase list confirms every paid item belongs to the SuperGrok family, meaning basic chat access doesn’t require payment at all. What xAI has never done, according to felloai.com, is publish an actual usage number for that free tier — no message cap, no daily limit, nothing official. A number circulating online (something like “10 messages every 2 hours”) has no official source behind it, so we’re not repeating it as fact.

What we can say about the free tier: it runs on a lighter model (Grok 4 Mini rather than the full Grok 4), includes basic real-time web and X search, has a restricted voice mode, and lost image and video generation entirely as of March 19, 2026. Access requires an X account, and in Taiwan specifically, credit card verification is required even to use the free version — an unusual friction point for something that costs nothing.

🔍 AMPM exclusive check

Here’s what our check found that the vendor page does not spell out, and where it genuinely differs from what you’d assume from a glance at Grok’s site. First: a “200 OK” on a pricing page sounds like success, but in this case it’s an empty shell — the actual prices only render client-side, and the verification wall between us and that rendered page is the real reason we couldn’t read it directly, not a dead link. Second: x.ai/grok’s 403 responses, three times in a row, mean the server is actively refusing the request — that’s meaningfully different from the page not existing, and most casual visitors would just assume “it’s down” rather than “it’s blocking me.”

Third, and most interesting: digging into Grok’s page configuration data, we found two internal flags — temp_supergrok_heavy_discount_enabled and supergrok_paywall_free_trial_zero_price — sitting in the HTML setup with no readable terms attached. These flags suggest xAI has built machinery for a free trial and a Heavy-tier discount, but neither comes with public conditions we could verify. Separately, the SuperGrok Heavy plan’s own listed text promises “67% off for 3 months, then US$300/month” — that’s real text in the plan data, not a flag, but it carries no stated end date for the offer itself. So we have three separate signals (two hidden flags, one promo line) pointing at “there might be a deal,” and zero confirmed terms to tell a reader whether that deal is live right now. That’s a real gap between what the official page implies and what it actually discloses — not us dressing up common knowledge.

☀️ AMO, the budget-minded cat

AMO’s question is simple: is free enough, and is paying worth it? The free tier clears the first bar — it’s actually US$0, confirmed by what Apple requires Grok to disclose, not a disguised trial. You get real-time search and basic conversation with no card charge, though Taiwan users still need to verify a credit card just to activate the free account, which is an annoying step for something that’s supposedly costless. The bigger problem is that xAI has never published a usage ceiling for free use — no daily message count, no token limit, nothing. That means a budget user has no way to plan around the free tier; you just use it until you hit a wall you didn’t know was there, and since March 2026 that wall also means no image or video generation at all on free.

If you do want to pay, the ladder is steep: US$10, US$30, US$100, US$300 a month, with a US$300/year option sitting at the second tier (SuperGrok, not Heavy — don’t confuse the two “300"s). For AMO, the US$10 Lite tier is the only one that looks like a measured step up from free: it adds 2x longer conversations and one “Expert mode” AI agent slot, which is a modest, legible upgrade. Jumping straight to US$30 SuperGrok adds real image/video generation (HD 720p, 30-second clips) and 5x longer conversations — that’s the tier where paying starts looking genuinely worth it, assuming the free tier’s invisible limit is already cramping you. The Heavy tier’s “67% off for 3 months” is the one AMO won’t bank on: no end date on the offer, so budget planning around it is guesswork.

🌙 PIMI, the performance-minded cat

PIMI cares whether Grok actually performs, not what it costs. The tier structure tells a fairly clean story about where the real capability jumps are. Free tier runs on Grok 4 Mini, the lighter model — fine for casual use, but a deliberate downgrade from the flagship. The jump to paid SuperGrok tiers brings “higher usage of best models,” faster response speed, and more capable code tools, plus voice conversations that run longer than the free version allows.

The real performance ceiling is Heavy, at US$300/month: “fastest speed, highest usage,” the most capable model tier, and — unlike the lower tiers — multi-agent team collaboration, where several AI agents work together rather than one at a time. Heavy also adds one-click app building: describe an app in a single prompt and deploy it to the web, plus a bundled X Premium+ subscription and priority support. SuperGrok Plus, at US$100/month, sits as a usage-quota step between SuperGrok and Heavy rather than adding new features — it’s more of the same at a higher ceiling, not a different tool.

On compliance basics: Grok’s output can be used commercially, and nothing produced carries a watermark, which matters if you’re generating content for client work. The real performance risk PIMI flags isn’t model quality — it’s the fuzzy line between free and paid: because xAI hasn’t published what “free” actually means in numbers, a workflow that leans on Grok for anything time-sensitive can get rate-limited without warning, and you won’t know in advance where that line sits.

Verdict: who should use it, who should skip it

Use Grok free if you want real-time X-integrated search and don’t mind an undefined, possibly-tight usage ceiling — and budget the friction of credit card verification in Taiwan even for the free tier. Pay for SuperGrok (US$30/month) if you specifically want its image/video generation and longer conversations, since that’s where the feature jump is clearest and the price is independently confirmed by a second source. Skip Heavy’s “67% off” promo as a reason to buy right now — there’s no end date attached to it anywhere we could verify, and the hidden discount flags on the page don’t resolve into actual terms. Skip the whole platform if you need a documented, predictable free-tier quota for planning a workflow — xAI simply hasn’t published one, and that’s not something we can fill in for them.
