Best LLM Monitoring Tools for Agencies

A client emails you: "Are we showing up in ChatGPT yet?" You pause. You are not sure, and you do not have a report to send back. If that feels uncomfortable, take a breath. You are not behind. Almost every agency is working this out at the same time you are.

Here is the reassuring part. You do not need to build an answer-engine team to keep up. You need one tool that can monitor client brands across LLMs, from one login, with a clean report you can put in front of each account.

That is what this guide is for. Picking from the best LLM monitoring tools for agencies comes down to four things, and those four things are exactly how we ranked the shortlist below. Let's walk through them together, then look at each tool in detail.

How we picked these tools

Agency LLM monitoring is a different job than monitoring one brand. You are juggling a portfolio, a margin per client, and a renewal conversation every quarter. So we scored each tool against the four criteria that actually decide whether it survives your delivery workflow.

1. Multi-client workspaces. Can you run each client in its own isolated space, with its own prompts and competitors, without one account bleeding into another?
2. Cross-model coverage. Does it track the engines your clients care about: ChatGPT, Perplexity, Gemini, Claude, Google AI Mode, and Copilot?
3. Per-prompt tracking at scale. Can you follow mention and citation rates prompt by prompt, across enough prompts to cover a whole roster?
4. Client-ready reporting. Can you hand a client a report that looks like it came from you, not from a tool they have never heard of?

We looked at four tools agencies actually shortlist: DeepSmith, Profound, Otterly.AI, and maxAEO. Every price, engine count, and feature below comes from each vendor's public pricing and product pages. Where a vendor keeps something behind custom pricing, we say so rather than guess.

DeepSmith lands at number one here, and we will be honest about exactly why, including where a competitor is the better call for you. That matters more than a ranking. Let's dig in.

What LLM monitoring actually tracks

Before the tools, a quick grounding. It makes every comparison below easier to read, and it gives you the language to explain the service to a client who has never heard of any of this.

Three numbers do most of the work. Mention rate is how often an AI names your client's brand in an answer. Citation rate is how often it links to their pages as a source. Share of voice is their visibility measured against competitors, so a client can see whether they are winning or trailing in the answers that matter. A good tool tracks all three, per prompt, over time.

Why per prompt? Because a client does not care about visibility in the abstract. They care about the exact questions their buyers ask. "Best CRM for small teams." "Is X worth the price." You define those prompts, the tool checks them on a schedule, and the trend line tells you whether your work is moving the needle.

That is the reassuring truth about agency LLM monitoring. It is not magic. It is a handful of clear metrics, tracked consistently, turned into a report a client can understand. Every tool below does that core job. The differences are in how well they do it across many clients at once, how many engines they reach, and how the report looks when it lands.

The tools at a glance

Keep this table handy as you read. The detail underneath is where the real fit lives.

1. DeepSmith

Best for: agencies that want the monitoring and the content in one place, so tracking a gap and closing it are not two separate tools and two separate logins.

Most tools on this list tell you where a client is invisible in AI answers. DeepSmith tells you that, then helps you fix it. It is an AI search analytics and content production platform in one, and that combination is why it earns the top spot for agency work. You see the gap and you produce the on-brand article that closes it, from the same client context.

Start with the tracking. DeepSmith reports Mention Rate, Citation Rate, Share of Voice, and Visibility Trend across ChatGPT, Perplexity, Gemini, Claude, and Google AI Mode. You define the prompts your client's buyers actually ask, and the platform checks them on a schedule. You get a per-platform breakdown, a competitor leaderboard, and the exact pages AI cites most. When a client asks how they stack up against a rival, the answer is already sitting in the dashboard.

Now the part that saves your margin. Every client lives in its own workspace, fully isolated, with its own context, content, and plan. Each workspace is billed and limited on its own, and you invite teammates as owners or members per account. One client's brand voice never leaks into another client's drafts. That isolation is the whole game when you monitor client brands across LLMs for a dozen accounts at once.

Then there is production, which none of the other three match. Content Studio takes an idea to a finished article: the Writer researches it, grounds it in the client's stored context, adds internal and external links, a cover image, and publish-ready metadata. Autowrite can run that on a schedule with no one in the app, landing drafts in Produced Content for review. You publish straight to WordPress, Strapi, Webflow, or a webhook. Every finished piece ships with social posts ready to copy, so you deliver a channel plan, not just a blog post.

Onboarding is built for how agencies actually start. Signup to a working workspace takes minutes, with the brand brief, competitors, starter tracking prompts, and a first batch of ideas populated before you pay. That matters when you land three logos at once and cannot spend a week teaching a tool each client. The context you set once feeds every module after, so drafts come out on-brand per account without re-briefing. If the fear you know best is "onboarding a new client takes weeks before we produce anything good," this is the part that answers it.

Key features:

• Five tracked engines: ChatGPT, Perplexity, Gemini, Claude, Google AI Mode (coverage rises by plan tier).
• Mention Rate, Citation Rate, Share of Voice, and Visibility Trend, with a competitor leaderboard and page-level citation attribution.
• Multi-Workspace structure: each client isolated, billed and limited independently.
• Content Studio, the Writer, Autowrite, Repurpose, and the Apps Library for content and distribution.
• Pricing: Pro $99/mo, Grow $199/mo, Scale $399/mo (or $80, $160, $299 billed annually), plus custom Enterprise. A 7-day free trial with real data and drafts before you pay, no long-term contracts.

One honest limitation: full five-engine coverage sits on the Enterprise tier. Pro tracks ChatGPT only, Grow adds Perplexity, Scale adds Gemini. White-label reporting is export to Looker Studio rather than a branded dashboard inside the product, so if a native white-label report is your single most important requirement, read the Otterly.AI section closely before you decide.

2. Profound

Best for: mid-market and enterprise teams that want the deepest answer-engine analytics across the widest set of engines, and can absorb a higher monthly floor for multi-model coverage.

Profound is built around a Monitor, Create, Operate framework, and its analytics run deep. Its Answer Engine Insights give you per-prompt citation and mention rates with full answer history, and Prompt Volumes show aggregate query volume across AI search engines, so you can see not just how a client performs but how much demand a prompt carries. There is also Shopping Agent Analytics, which is a genuine edge if your clients sell products through AI shopping surfaces.

For agencies, Profound offers an Agency Growth plan with per-client workspaces and credit allocations per workspace. Engine coverage is the widest here at the top: Enterprise tracks up to ten engines, including ChatGPT, Perplexity, Google AI Mode, Gemini, Copilot, Meta AI, Grok, DeepSeek, Claude, and Google AI Overviews. If a client demands proof that you are watching every surface their buyers might use, that breadth is hard to beat.

Profound also leans into workflow, not just analytics. Its Agents module and Agent Templates push toward content and operational tasks, and Profound University plus its AEO Report give your team and your clients a shared vocabulary. This is a platform aimed at organizations that want depth and are willing to talk to sales to get it.

Key features:

• Answer Engine Insights with per-prompt citation and mention rates and answer history.
• Prompt Volumes for aggregate query demand across engines.
• Shopping Agent Analytics and an Agents module for content workflows.
• Up to 10 tracked engines on Enterprise, with SSO, SOC2, and API access.
• Pricing: Starter $99/mo (billed yearly, ChatGPT only), Growth $399/mo (three engines), Agency Growth and Enterprise custom.

One honest limitation: the Starter plan covers ChatGPT only, so real multi-engine tracking starts at $399/mo Growth. Agency Growth and Enterprise pricing are not published, and white-label reporting is not advertised on the public pricing page. If you want to know your per-client cost before a sales call, that opacity is worth weighing.

3. Otterly.AI

Best for: agencies whose core deliverable is the monitoring report, and who want unlimited client workspaces plus true white-label output from a modest entry price.

If your clients pay you mainly to watch and report, Otterly.AI is built for exactly that shape of work. From the Standard plan up, you get unlimited workspaces separated by client, unlimited brand reports with citation analysis, sentiment tracking, and competitor comparison, and single-invoice billing across every workspace. There is a Partner Program with co-marketing, and Pitch Workspaces let you run a custom audit for a prospect before they sign.

The reporting story is the standout. Otterly.AI offers white-label LLM monitoring through a native Google Looker Studio connector, so the report a client sees carries your brand, not the vendor's. Base coverage spans ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot, with Claude, Google AI Mode, Gemini, and Grok available as add-ons.

The extras are built for the sales side of agency life. Pitch Workspaces let you run a custom audit for a prospect and walk into the pitch with real data about their AI visibility. Single-invoice billing keeps your finance side simple as the roster grows, and the Partner Program adds co-marketing if you want to lean into the channel. For a monitoring-first shop, the pieces fit together neatly.

Key features:

• Unlimited client workspaces from the Standard plan upward.
• Native Looker Studio connector for white-label client reports.
• Brand Visibility Index, Domain Ranking, Link Citations Analysis, and a GEO Audit.
• Prompt Research Tool with keyword-to-prompt conversion, plus support for 50-plus countries.
• Pricing: Lite $29/mo, Standard $189/mo, Premium $489/mo (or $25, $160, $422 billed annually), plus custom Enterprise.

One honest limitation: base plans cover only four engines, and Claude, Google AI Mode, Gemini, and Grok are paid add-ons rather than included. White-label runs through Looker Studio, so you are working inside Google's reporting layer rather than a fully bespoke dashboard. For pure monitoring-and-reporting agencies, that is a small price. For teams that also want to produce the content, it is a gap.

4. maxAEO

Best for: solo operators and small agencies who need a low-cost way to start, or portfolio operators who want up to four brands under one affordable tier.

maxAEO keeps things lean and cheap. Its Starter plan is $19/mo for a single brand, and its Pro tier at $399/mo covers up to four brands with 400 prompts and a full year of data retention. That makes it a sensible first step if you are testing agency LLM monitoring on a couple of accounts before you commit budget to a heavier platform. Enterprise opens up unlimited brands for larger portfolios.

It tracks roughly six platforms: ChatGPT, Gemini, Perplexity, Claude, Copilot, and Grok. Base plans monitor four of the six, and Enterprise unlocks all of them. Each brand can track competitors, so you still get a benchmarking view even at the lower tiers.

The appeal is the low floor and the clean tiering. If you want to monitor client brands across LLMs for a few small accounts without a sales call or an annual commitment, maxAEO gets you a working dashboard fast. Data retention scales with the plan, so heavier accounts that need a longer history point toward Pro or Enterprise.

Key features:

• Multi-Brand Matrix on Pro: up to 4 brands, 400 prompts, competitor tracking per brand.
• Roughly six tracked platforms, with all six on Enterprise.
• Tiered data retention: 30 days on Starter, 90 days on Growth, a full year on Pro.
• Pricing: Starter $19/mo, Growth $149/mo, Pro $399/mo (or $15, $119, $319 billed annually), plus custom Enterprise.

One honest limitation: base plans cover only four of the six platforms, so full coverage means Enterprise. White-label reporting is not advertised on the public pricing page, and agency-specific workspace management and integrations beyond CSV or API export are thinly documented. If client-ready, branded reporting is central to your offer, confirm those details with maxAEO before you build a service around it.

How to choose the right tool for your agency

Four solid tools, four different shapes of agency. Here is how to match them to yours without second-guessing.

Pick DeepSmith if your deliverable is content, not just a report. When a client wants to see the gap and then see it closed, one platform that tracks visibility and produces the on-brand article saves you a tool, a login, and a stack of manual work. The multi-workspace isolation keeps every client's voice its own. This is the fit for agencies scaling output across a growing roster.

Pick Profound if you serve mid-market or enterprise clients who need the widest engine coverage and the deepest analytics, including prompt volumes and Shopping Agent data, and the budget can carry the higher floor.

Pick Otterly.AI if monitoring and reporting are the whole job. Unlimited workspaces and a native white-label Looker Studio connector make it a clean fit when the report is what the client pays for and you do not need to produce content in the same tool.

Pick maxAEO if budget is the deciding factor and you want to start small. A $19 entry point or a four-brand Pro tier lets you prove the service before you invest in a heavier platform, as long as you accept partial engine coverage at the lower tiers.

One more lens helps: think about your margin, not just the features. The manual work around this service, pulling data, building a deck, and rewriting drafts every month, is what quietly eats your delivery profit. A tool that only monitors leaves the reporting and the content on your plate. A tool that also produces the content takes real hours off it. So weigh the monthly price against the hours it saves you per client, not against the sticker alone. The cheapest tool is rarely the cheapest to deliver with.

Still torn? Start with the client you are most worried about losing. Map what that one account actually needs, tracking depth, engine mix, or a branded report, and let that single decision pick your tool. You can always grow into more.

Ready to see your clients' AI visibility?

You do not have to solve this for the whole roster this week. Pick one client, set up their prompts and competitors, and look at the first report together. That one small step turns "I am not sure" into "here is exactly where you stand," and it is the fastest way to see how a tool actually fits your workflow. Start a DeepSmith free trial and pull real data and a real draft for one account before you decide anything bigger.
