RadarKit AI's price was $29/mo, or $99/mo, depending which review you trusted. Here's what to do when a vendor's own price won't hold still.

Two weeks ago, researching this blog's own competitor list, we found something worth flagging: independent sources describing RadarKit AI's pricing didn't agree with each other. One cluster showed a $29/mo entry tier. A separate cluster described a $99/mo-billed-annually tier that only covered ChatGPT. Tonight, re-checking that same price fresh, five differently-worded searches turned up a single, consistent ladder instead — Lite $29/mo, Growth $79/mo, Pro $139/mo, Enterprise custom — and the $99/mo structure didn't resurface anywhere. We can't tell you which picture was ever "wrong," because we can't fetch RadarKit's own pricing page directly to settle it (more on that below). What we can tell you is more useful than a verdict: a young vendor's self-reported price moved, or looked like it moved, in the two weeks between our checks — and that's exactly the kind of thing worth catching before you're the one finding out the hard way, mid-trial, what the real number is.

What two checks, 15 days apart, actually found

On 2026-08-03, building out this site's competitor list, we logged RadarKit's pricing as genuinely disputed: one source cluster cited a Lite-through-Enterprise ladder starting at $29/mo; a second, separately-sourced cluster described a $99/mo annual Starter tier (ChatGPT only, 50 prompts) and a $399/mo annual Growth tier (3 engines, 100 prompts). Both clusters agreed on one thing: every plan runs a 7-day free trial, with no permanent free tier. Tonight, running the same check again, every source that surfaced — RadarKit's own blog, aggregator "best AI visibility tools" roundups, and Trustpilot — pointed to one ladder: Lite $29/mo, Growth $79/mo (marked "Most Popular"), Pro $139/mo, Enterprise custom-priced. The second cluster simply didn't come up, in five separate queries. Trustpilot's own page (11 reviews, none visibly about billing) also surfaced a detail neither of our earlier sources had: a 48-hour refund window after your card is first charged. We tried to settle the discrepancy the direct way — fetching radarkit.ai and trustpilot.com ourselves — and both attempts were blocked before they reached the page, so everything above is search-corroborated, not something we confirmed with our own eyes on the live page. That's a real limit on this post, stated plainly rather than smoothed over.

Why this matters more for a young vendor than an established one

This isn't a claim that RadarKit is misleading anyone — a startup's own pricing page changing twice in a month is a completely normal thing for a fast-moving company to do, and review aggregators are notoriously slow to catch up when it happens. That's precisely the point: in a category this new — AI Search Visibility Monitoring, not "SEO tooling" — most of the vendors are exactly this young, and their public pricing record hasn't had years to settle the way an established tool's has. The alternative to checking is trusting whichever number the first search result gives you, which is how a buyer ends up expecting $29/mo and discovering, after a 7-day trial converts, that the plan they actually need costs $79 or $139.

The checklist to run before you pay a young AI-visibility vendor

1. Load the vendor's own pricing page yourself, today, and screenshot it with the date visible — don't trust a review site's cached number, even a recent one.
2. Read the trial terms specifically: is it a genuinely free tier, or a countdown before your card is charged automatically?
3. Check whether the price is flat per month, or metered by credits/prompts — a metered plan's real bill depends on how busy your month is, not the sticker price.
4. Cross-check the same price on two independent sources dated within the last few weeks of each other. If they disagree, that disagreement is your answer, not a tiebreaker to resolve by picking the lower number.
5. Confirm what happens if you forget to cancel — a stated refund window (RadarKit's own page reportedly gives 48 hours post-charge) is worth knowing before the trial clock starts, not after.

Real buyers already complain about exactly this, elsewhere in this category

Pricing unpredictability isn't a RadarKit-specific worry — it's one of the most consistently named complaints in this whole product category. A G2 reviewer of AthenaHQ put it in five words: "The credit-based pricing creates unpredictable monthly costs." A G2 reviewer of Semrush went further: "I dislike their sales team, they aren't helpful, their pricing is opaque and confusing, and their team doesn't try to help you." A separate reviewer complaint pattern — Profound's cost-per-prompt running higher than expected for the plan advertised — is a third, independent version of the same theme: buyers in this category keep getting surprised by what they actually owe, not by what a tool actually does.

Where PingMyBrand stands, honestly

We're not neutral here — we compete with RadarKit for the same buyer — so the honest version of our own pitch: PingMyBrand's pricing is one flat number per tier, published, unmetered, and it hasn't needed a "reported, unconfirmed" caveat because there's nothing to reconcile across sources — $19/mo Solo, $49/mo Starter, $199/mo Agency, the same numbers whether you check today or next month. The full report itself is free, instantly, with no signup and no trial clock counting down while you decide. The fuller head-to-head against RadarKit covers what they do well too — real location-level tracking across 50+ countries is a genuine strength we don't match — so this isn't the whole comparison, just the pricing piece of it.

Verify it yourself before you verify anything else

Whichever AI-visibility tool you're evaluating, RadarKit or otherwise, load its actual pricing page yourself before you trust a single third-party number, including ours above — this post is dated 2026-08-18 for exactly that reason, so you can tell at a glance whether it's still current when you're reading it. Then run PingMyBrand's free scan on your own domain: no signup, about a minute, and you'll have a real number of your own to bring into whatever comparison you're making next.
