Rank Prompt Review 2026: The Brand Count Grows 100x, the Credits 13x

Rank Prompt is one of four tools in this comparison that puts Claude on its cheapest plan, and it is the only one we have found that charges extra for Gemini. Both facts come from the same line on its pricing page, and that line is worth more than the price list.

The tiers climb from $470 a year to $2,870. Along the way the number of brands you may track multiplies by a hundred, exactly, while the credits that measure them multiply by thirteen and a third. At the top plan, a fully loaded agency has two credits per client per month.

Disclosure: EchoWi competes with Rank Prompt. Every price, credit allowance, brand count, seat count and engine name below was read from Rank Prompt’s own pricing page on 7 August 2026, and every derived figure shows its arithmetic so you can repeat it.

The short version

1. From $470 a year, and annual is the only billing offered. There is no monthly price anywhere on the page.
2. Six engines on every tier, including the cheapest, with no coverage ladder.
3. Claude is in the base credit. Gemini and Grok are not. That is backwards from the rest of this market.
4. Full six-engine coverage costs three credits, not one, so every headline allowance is a third of what it looks like.
5. The volume discount stops at the Agency tier. The plan above it costs fractionally more per credit.

What it costs, verified

Every tier names the same six platforms: ChatGPT, Perplexity, Google AI Mode, Gemini, Claude and Grok. A 7-day trial with 50 free prompts comes with the paid plans. Credits reset monthly on the billing date and, in the page’s own words, “don’t roll over”.

The line that changes all of it

Buried in the pricing calculator, not the plan table:

the four standard engines are bundled into one credit per prompt, and each premium engine adds one on top

The four standard engines are ChatGPT, Perplexity, AI Mode and Claude. The two premium ones are Gemini and Grok. So one prompt measured across everything Rank Prompt sells is three credits, not one.

That divides every allowance on the page by three:

Nothing here is hidden and nothing is misstated. The page publishes both numbers and the rule that connects them, which is more than most of this market does. But the plan table shows 150 and the calculator shows the divisor, and a buyer comparing tools on a Tuesday afternoon reads the first number.

A Gemini answer costs four times a ChatGPT answer

Follow the same rule the other way and it produces the oddest fact in this review.

One credit buys a prompt on four engines. One credit also buys a prompt on Gemini alone. So at the Agency tier, where a credit works out at $0.119:

Four times the price for the same question on a different model. There may be a good reason, and API costs differ between providers, but the page does not give one.

What makes it strange is which engine sits on which side. Several tools in this comparison treat Claude as the premium one, kept behind an unpriced Enterprise tier: Writesonic, Cognizo and Siftly all draw that line. Rank Prompt bundles Claude at $470 a year and charges a premium for Google’s model instead. Athena HQ goes further still and covers Claude on its free tier.

If Claude matters to your category, this is among the cheapest ways to measure it.

Where the ladder stops paying

Divide each annual price by the credits it buys in a year:

The discount is steep and then it is over. Starter to Pro nearly halves the unit price. Pro to Agency takes another 16% off. Agency to Agency Plus takes nothing off at all, and the arithmetic puts Agency Plus four hundredths of a cent above the tier below it: $0.11917 against $0.11958.

That is not a criticism, it is a buying instruction. Agency Plus does not sell cheaper measurement, it sells brand slots and seats. If you are climbing to it for volume, you are paying $2,870 for what two Agency plans would give you at $2,860, and the tier below already reached the floor.

The number that does not scale with the others

Now put the brand allowance beside the credits.

From Starter to Agency Plus the brand count multiplies by exactly a hundred, the credit allowance by thirteen and a third, and the price by just over six. The three numbers advertised together move at three different rates, and the one printed largest moves fastest.

Read the last column honestly. An agency that actually filled its thousand brand slots would have two thirds of one six-engine prompt per client per month. Not two thirds of a report. Two thirds of a single question, asked once.

No agency fills those slots, and that is the point. The brand count is headroom, not capacity, and it is doing the work of making a plan feel large. The credits are the capacity, and they are the number to buy on.

To be fair to Rank Prompt: this shape is not unique to it, and at least here you can calculate it. The Agency tier’s 1,000 credits against 500 brands is legible in a way that “unlimited brands” on some competitors’ pages is not, because unlimited brands against a fixed credit pool is the same trade with the arithmetic removed.

What a prompt costs here, against the rest

Per single engine answer, the standard-engine figure of $0.030 at Agency sits mid-table: close to Nightwatch at €0.027 on its top tier, cheaper than Athena HQ at $0.082, and well above Siftly at $0.0055.

The comparison has a caveat that runs the other way from Nightwatch’s. Nightwatch’s per-answer cost looks good because you are also buying a rank tracker. Rank Prompt’s looks worse than it is because a credit buys four answers at once, and worse again if you insist on Gemini.

Is the allowance enough?

The page states monthly credit totals and no refresh cadence, so how the budget is spent is your decision rather than the product’s. That is unusual and mostly good: nothing forces you to spread thin.

It also means the sampling question lands entirely on the buyer. Starter’s 50 full-coverage prompts a month can be 50 questions asked once, or 10 questions asked five times, and those are very different products. For a mention rate near 30%, five observations carry a 95% confidence interval of roughly plus or minus 40 points, and one observation carries no interval at all because it is a draw rather than a rate. The arithmetic behind that is the same one we apply to every vendor here, including ourselves.

Our own measurements this month sharpened why it matters. Re-running one question in three markets returned an almost identical shape and an almost completely different set of stable sources. A credit budget spent on breadth will tell you which questions mention you. Only a budget spent on repetition tells you whether that will still be true next week.

Where Rank Prompt is the right call

You want Claude and Perplexity coverage cheaply, you can commit to a year, and you are tracking a handful of brands rather than hundreds. At $470 for six engines with no coverage ladder, the entry plan gives a small team more engines per dollar than most of this market.

Agencies with real client volume should buy Agency and stop there, because that is where the unit price bottoms out.

Where it is the wrong call

You need monthly billing. There is none, and in a category whose entire premise is that answers move week to week, a twelve-month commitment is a real ask of a buyer who is still evaluating.

You need Gemini specifically. It is the most expensive engine on the platform per answer, and a tool that prices all engines equally will cost less for that job.

You are an agency planning to use the brand allowance as capacity. Buy on credits, then check the brand count is not the number persuading you.

What we could not verify

• Whether prompts run on a schedule or on demand, and what happens to a tracked brand once its credits are spent.
• Seat count on Starter, which the table does not state.
• Whether a failed or empty answer consumes a credit.
• Enterprise pricing, and whether it changes the credit rule.
• Whether the 20% annual saving is against a monthly price that exists, since no monthly price is shown.

The last one is worth a line. The page carries a “Save with annual” toggle of the kind that normally reveals a monthly column, and no monthly column appears. We are reporting what the page showed us.

Rank Prompt versus the alternatives

Against the funded platforms in this category, Rank Prompt is cheap and legible: six engines at the entry price, a published credit rule, and enough numbers on one page to work out what you are buying. That is not common here, and the tools that publish least tend to look best in a feature table.

Against the other tools that publish enough to check, it lands in the same place they do. Nightwatch gives thirty answers per prompt on every tier and sells breadth. Siftly raises depth as the tier climbs. Rank Prompt sells a credit pool and lets you choose, which is the most flexible of the three and the one that most requires you to know what you are doing.

Every price here sits alongside the rest, each read from the vendor’s own page, in our comparison of every tool we verified.

Common Questions About Rank Prompt

How much does Rank Prompt cost?

$470 a year for Starter, $855 for Pro, $1,430 for Agency and $2,870 for Agency Plus, with Enterprise at custom pricing. Those work out at $39.17, $71.25, $119.17 and $239.17 a month, and annual is the only billing the page offers.

How many AI engines does Rank Prompt track?

Six on every plan including the cheapest: ChatGPT, Perplexity, Google AI Mode, Gemini, Claude and Grok. The list does not change as you climb, which only three vendors out of the twenty-four we catalogued can say.

What does one Rank Prompt credit buy?

One prompt across the four standard engines, which are ChatGPT, Perplexity, AI Mode and Claude. Gemini and Grok each add one credit on top, so a prompt measured on all six engines costs three credits. A Starter plan’s 150 credits is therefore 50 full-coverage prompts a month, not 150.

Do Rank Prompt credits roll over?

No. The page states that credits reset monthly on your billing date and do not roll over, so an unused month is lost rather than banked.

Is the Agency Plus plan better value than Agency?

Not per credit. Agency works out at $0.119 per credit and Agency Plus at $0.120, so a little over double the spend buys exactly double the credits and no discount at all. What Agency Plus adds is brand slots, from 500 to 1,000, and seats, from 10 to 25. Buy it for those, not for volume.

Is Rank Prompt good value for an agency?

On credits, yes, at the Agency tier where the unit price bottoms out. On brands, read the arithmetic first: 1,000 brands against 2,000 credits is two credits per client per month, which is two thirds of one six-engine prompt. The brand allowance is headroom rather than measurement capacity.
