Monitoring tool prices range from $25 to over $3,000 a month, and the sticker price rarely tells you what you are buying. An ai search monitoring tool cost per month figure only means something once you know how many prompts it tracks, across which engines, and how often it refreshes. This guide puts those variables on one scale so you can compare vendors on equal terms.

Quick answer

**Published prices start around $25 to $29 per month for entry tools**, with mid-tier multi-engine platforms running roughly $100 to $500 per month. Enterprise AI search analytics tools are often quote-only, with published examples from about $1,500 to $25,000 per month, according to AI Growth Agent. The right number depends on prompt count and engine coverage.

Key Takeaways

Published prices cluster into three bands.
Price per month means little without a unit.
Prompt count, engine coverage and refresh frequency are the three levers that set a monitoring tool's monthly price.

What does an AI search monitoring tool cost per month?

Published prices cluster into three bands. Entry plans start low: Radarkit and Otterly AI list from $29/month, and Keyword AI Tracker from $25/month, according to Radarkit's survey of AI visibility tools. Mid-tier multi-engine platforms run roughly $100 to $500/month, per AI Growth Agent. Enterprise tools are often quote-only, with published examples from roughly $1,500 to $25,000/month. The average across the tools Radarkit lists is about $337/month, a figure that hides how wide the spread is.

Tool	Starting price	What the price buys
Keyword AI Tracker	$25/month	Entry tier, per Radarkit
Otterly AI Lite	$29/month	15 prompts, per Otterly pricing
xSeek Essential	$49/month	Entry tier, per xSeek
Peec AI	About $95/month (€89)	Per Otterly comparison table
Semrush AI Visibility Toolkit	$99/month per domain	1 domain, 25 prompts, per Otterly table
Ahrefs Brand Radar	$828/month minimum	$129 base plus $699 all-index
seoClarity	Up to $3,000/month	Top of Radarkit's listed range

Prices are as published by each source at the time of research and change often. Verify before budgeting. OtterlyAI's Lite plan costs $29/month for 15 prompts, its Standard plan $189/month for 100 prompts, and its Premium plan $489/month for 400 prompts, according to Otterly's pricing page.

Why do the same-looking prices hide different products?

Price per month means little without a unit. Pepper's analysis of published vendor pricing puts Trakkr Scale at $500/month for 500 prompt-engine units, about $0.13 per prompt per engine. Otterly Premium works out to about $0.31, while Profound Starter at $99 for 50 prompts on one engine comes to about $1.98, a roughly 16x spread, according to Pepper. Profound Starter also tracks only ChatGPT. A cheap-looking plan covering one engine can cost far more per answer you actually measure than a broader plan that looks expensive.

Vendor	Cost per prompt per engine (Pepper)
Trakkr Scale	About $0.13
Otterly Premium	About $0.31
Profound Starter	About $1.98

Calculated from Pepper's published figures for the plans named, not from a vendor-stated metric. According to Otterly's pricing as reported by AI Growth Agent (November 2026), Lite tracks prompts across ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot, while Google AI Mode, Gemini and Claude are sold as paid add-ons.

What drives the monthly price up or down?

Prompt count, engine coverage and refresh frequency are the three levers that set a monitoring tool's monthly price. Prompt count is the number of questions you track. Otterly's own tiers scale from 15 prompts on Lite to 100 on Standard and 400 on Premium, at $29, $189 and $489 a month. Engine coverage is the second lever. Most tools track 3 to 6 engines, while OtterlyAI covers all 7 listed engines and 50+ countries and languages, according to Otterly's blog. Refresh frequency is the third lever. Specifically, the cadence of checks changes the bill:

Daily checks on a large prompt set cost more.
Weekly checks on a small prompt set cost less.
Refresh cadence often changes the bill more than most buyers expect.

Where do AI search monitoring tools hide costs?

The subscription is rarely the full bill for an AI search monitoring tool. Some tools meter usage in credits, which makes a monthly figure hard to predict. AthenaHQ prices in credits per Pepper's analysis, and Scrunch's Core plan starts at $250/month according to xSeek's comparison. Add-ons also stack.

Otterly lists Google AI Mode, Gemini and Claude as paid add-ons on its Lite plan, per AI Growth Agent's pricing review. Monitoring only shows where your brand is absent. Acting on that data requires producing pages, and producing pages consumes writing, review and CMS time. However, no monitoring subscription line item covers that production and maintenance work, so buyers should budget for it separately.

Which vendors publish prices and which hide them?

Pricing transparency varies sharply across AI search monitoring vendors. Otterly, Radarkit and Semrush publish starting prices, and Semrush's AI Visibility Toolkit is listed at $99 per month for one domain and 25 prompts, according to the Otterly comparison table. Scrunch's pricing page does not mention SOC 2, even though Pepper notes that Scrunch is widely described as SOC 2 certified.

Buyers should verify that SOC 2 claim directly with Scrunch before relying on it. Enterprise AI search analytics platforms often withhold figures entirely, and AI Growth Agent reports that such tools are frequently quote-only. Where a vendor's pricing is not publicly documented, the practical step is to request a written quote and compare each line item against the others.

If a price can only be obtained from the vendor's sales team, that price cannot be benchmarked against the rest of the market. Requesting quotes in a consistent format lets buyers compare Otterly, Semrush, Radarkit and quote-only platforms on equal terms.

How should you choose the right monthly budget?

Start from the decision, not the cheapest plan. Count the prompts that map to your buyers, decide which engines actually send you traffic, and set a refresh cadence your team will act on. Divide each candidate's monthly price by prompts times engines to get a comparable figure. Then add the cost of content production and maintenance.

Specifically, a tool that tracks your gaps but cannot help you close them automatically may cost less on paper and more in staff hours. Fastlook's Citation Analytics tracks exactly where your brand appears across major engines. Page Engine publishes the citation-ready pages that close the gaps it finds, so the monitoring and the response sit on one bill.

Frequently asked questions

How much does an AI search monitoring tool cost per month?

**Published prices start around $25 to $29 per month for entry tools**, with mid-tier multi-engine platforms running roughly $100 to $500 per month. Enterprise AI search analytics tools are often quote-only, with published examples from about $1,500 to $25,000 per month, according to AI Growth Agent. The right number depends on prompt count and engine coverage.

What is the cheapest AI search monitoring tool?

Keyword AI Tracker is the cheapest listed option, **starting from $25 per month**. Radarkit and Otterly AI start from $29 per month, according to Radarkit's survey. However, entry plans usually cap prompt counts. For example, Otterly's Lite plan covers 15 prompts. Some tools also add engines or features as paid add-ons, so the low starting price may not cover your full use case.

How do I compare AI monitoring tools with different pricing units?

Compare tools by converting each plan to a cost per prompt per engine. This standardises plans sold in different units, such as flat monthly prompt bundles or credits. According to Pepper's analysis, **Trakkr Scale works out to about $0.13**, Otterly Premium to about $0.31, and Profound Starter to about $1.98 on this basis, a roughly 16x spread. Divide the monthly price by prompts multiplied by engines tracked to place every vendor on the same scale.

What drives the price of an AI search monitoring tool?

Three factors dominate the price of an AI search monitoring tool: prompt count, engine coverage and refresh frequency. Otterly's tiers scale from 15 prompts at $29 to 400 prompts at $489 per month. Most tools track 3 to 6 engines. However, OtterlyAI tracks all 7 listed engines, so broader coverage and more frequent checks raise the bill.

Is AI search monitoring the same as LLM monitoring?

AI search monitoring and LLM monitoring overlap but differ in scope. AI search monitoring tracks whether your brand is cited in answers from engines such as ChatGPT, Perplexity and Google AI Overviews. LLM monitoring focuses more broadly on model outputs. Buyers focused on discovery and citations usually need AI search monitoring. However, buyers should confirm which engines a specific tool actually covers, because coverage varies. According to Otterly's blog, OtterlyAI tracks all seven listed engines, while most tools track three to six.

What hidden costs sit on top of an AI monitoring subscription?

Credit-based pricing, paid engine add-ons and enterprise setup fees can all raise the total cost. For example, Otterly's pricing lists Google AI Mode, Gemini and Claude as paid add-ons on its Lite plan, according to AI Growth Agent. Monitoring also reveals content gaps that someone must fill, which consumes writing, review and CMS time. Total cost of ownership therefore includes production and maintenance, not only the subscription line.

Which AI search monitoring tools have transparent pricing?

Otterly, Radarkit, Semrush and xSeek publish starting prices in the sources reviewed here. Scrunch and AthenaHQ show plan prices, although AthenaHQ uses credits. For example, Scrunch's Core plan starts at $250 per month and AthenaHQ's Self-Serve plan at $295 per month, according to the xSeek comparison. Enterprise platforms are frequently quote-only. Where a vendor's pricing is not publicly documented, request a written quote and compare it line by line.

Should I pay for a monitoring tool or a content platform?

Monitoring shows where your brand is absent, while a content platform helps you close those gaps. Fastlook combines Citation Analytics with Page Engine. However, Page Engine publishes AEO-optimised pages to WordPress, Webflow and Shopify. Compare the combined monthly cost against a monitoring tool plus the staff hours needed to produce the pages yourself.
