Key takeaways
- Otterly.AI is the cheapest way in (Lite from $25-29/mo, Standard $189/mo) and has unlimited seats and, from Standard up, unlimited workspaces. It is monitoring only.
- Peec AI has the cleanest dashboards and bundles Gemini and AI Mode as model options, but its standard tiers cap projects at 1, 2 and 5. Check its separate agency pricing page before you commit.
- Slate is a different animal: an execution platform with an Agency tier at $2,000/mo. It only makes sense if you want the tool to ship content, not just report.
- The three tools count usage in different units (prompts, prompts across engines, and AI answers), so a straight price-per-prompt comparison misleads.
- Whichever you pick, treat citation counts per engine with caution. Promptwatch Data shows engines cite very different numbers of sources.
Why these three get compared
They show up together in almost every 2026 roundup, but they are not really the same kind of product. Peec AI and Otterly.AI are trackers. You enter prompts, they run them against AI engines, and you get dashboards of mentions, citations and share of voice. Slate pitches itself as the next step: tracking tied to content production and workflows.
That matters for agencies. A tracker is a reporting tool you bill clients around. An execution platform is closer to a production tool that replaces labor. Slate's own blog sorts the market this way: monitoring-only tools (Peec, Otterly, Profound, BrandRank) for teams with five or more writers, and execution platforms like Slate for teams with one to three people covering content and SEO. That is vendor-biased, obviously, but the split is a useful way to think about it.
One more caveat: some of the comparison material online is written by the vendors. Otterly's list ranks itself, and Slate's list crowns Slate. I leaned on the official pricing pages for numbers and treated the rest as opinion.
Quick comparison table
| Slate | Peec AI | Otterly.AI | |

Peec AI
Peec is a Berlin company, and its pricing page now says it is trusted by 3,500+ brands and agencies. Older articles still quote 2,000+ marketing teams, so that number is stale.
Pricing
Prices are in euros per month. Every plan includes unlimited users and daily tracking.
| Plan | Price | Prompts | Projects |
|---|---|---|---|
| Starter | EUR 85 | 50 | 1 |
| Pro | EUR 205 | 150 | 2 |
| Advanced | EUR 425 | 350 | 5 |
| Enterprise | Custom, annual | Custom | Unlimited |
If you saw Pro quoted at EUR 199 somewhere, that is out of date. It is EUR 205 now. On the standard tiers you pick three models. Advanced adds multi-country and the Looker Studio integration. Enterprise unlocks up to 13 LLMs, API, SSO and the choice of daily or weekly tracking.
What agencies get
The obvious draw is unlimited seats and a clean interface. Reviewers keep praising the dashboards for being easy to show to clients who do not live in AI search. Peec has also been known for free pitch workspaces, which are handy when you are trying to win a prospect with their own visibility data. There is a separate agency pricing page at peec.ai/pricing-agencies. I could not verify what is on it, so read it directly before assuming the standard project caps apply to you.
That cap is the real issue. One client brand usually means one project. On the standard tiers, five projects is a ceiling a growing agency will hit quickly.
The feature list is broader than the old reputation as a basic tracker suggests: AI Shopping with SKU-level tracking, an ads library, brand perception, crawlability audits across 40+ bots, prompt volume scoring and a built-in agent. I could not confirm which tier gets which feature, because the comparison grid lost its tick marks in the scrape.
Weak spots: reviewers note a lack of deep optimization guidance, and the methodology is not publicly documented in detail.
Otterly.AI
Otterly is the budget entry point and it knows it. It is also a legitimately agency-capable product once you get past Lite.
Pricing
The pricing page shows two sets of numbers (looks like monthly versus discounted views), so treat the lower figures as annual-ish promo pricing and confirm at checkout.
| Plan | Price | Prompts | Notes |
|---|---|---|---|
| Lite | $25-29/mo | 15 | 1 workspace, Query Fan Out and prompt research tools |
| Standard | $160-189/mo | 100 | Unlimited workspaces, API, MCP, agent analytics, Data Studio connector |
| Premium | $489/mo | 400 | For mid-sized companies and agencies |
| Enterprise | Custom | 1,000+ | SSO, quarterly GEO health check, dedicated CSM |
Extra prompts run $99 per 100. All plans include unlimited team members, brands, competitors, countries and languages, plus daily tracking.
The add-on catch
ChatGPT, AI Overviews, Perplexity and Copilot come on every plan. Claude, Google AI Mode and Gemini are paid add-ons. Since AI Mode and Gemini are the two Google surfaces most agencies' clients care about, the real cost of a four-engine-plus-Google setup is higher than the sticker price. Peec, by contrast, lets you choose Gemini and AI Mode as part of your base model picks.
Agency angle
Unlimited workspaces from Standard is the strongest argument for Otterly if you manage many small clients. The research I pulled does not show the agency partner program or white-label details on the pricing page, though other reviews mention white-label reporting and centralized billing. Ask sales to confirm in writing.
The honest criticism, from a Reddit tester quoted in Ziptie's roundup, is that it tells you that you are losing but not why. Manual prompt entry and no automated query discovery came up too. Think thermometer, not GPS. That is fine if reporting is the job.
Slate
Slate is priced and built differently, so comparing its $499 entry point to Otterly's $25 is a little unfair. They are not selling the same thing.
Pricing
| Plan | Price | Credits | AI answers/mo | Pages monitored |
|---|---|---|---|---|
| Growth | $499 | 15,000 | 10,000 | 1,000 |
| Scale | $999 | 50,000 | 20,000 | 5,000 |
| Agency | $2,000 | 100,000 | 50,000 | 10,000 |
| Enterprise | Custom | Custom | Custom | Custom |
Annual billing saves 20%. Growth includes 1 user and 1 workspace. Scale adds custom users and workspaces, 1:1 onboarding and a dedicated account manager. All plans track ChatGPT, Perplexity, AI Overviews and AI Mode. Claude and Gemini come as add-on packs of 1,000 answers, and only Enterprise includes all six platforms.
Reading the units
An AI answer is one response from one platform for one prompt in one location. So 333 prompts tracked daily on a single platform eats roughly 10,000 answers a month. The same prompts run weekly use about 1,450. Tracking draws from its own allowance and does not burn credits. Credits pay for agent work like content production, Cowork tasks and workflow runs. If credits run out, workflows pause.
That means a Slate agency plan is only good value if you actually use the execution side. If you just want reports, you are paying $2,000 for a tracker.
The pricing unit problem
The single biggest trap when comparing these is the unit.
- Peec counts prompts, and you choose roughly three models per standard plan.
- Otterly counts prompts across four base engines, with add-ons for the rest.
- Slate counts answers, which is prompts x platforms x frequency x locations.
So 150 prompts on Peec Pro and 100 on Otterly Standard are not interchangeable with 20,000 Slate answers. Convert everything to the same scenario first: how many client brands, how many prompts per brand, how many engines, how often. Then price it.
The same caution applies to the metrics. Promptwatch Data's average sources per response report shows ChatGPT citing about 5 sources per web-search answer, Google AI Overviews about 10, and Perplexity almost exactly 10 every day. Copilot swung from under 2 to nearly 17 sources within a few weeks before settling low. So a citation count in one tracker is not comparable across engines, and Copilot readings are best judged on monthly trends rather than weekly ones. Perplexity makes a stable test bench if you want to sanity-check any tool.
Which one fits which agency
Small agency testing the waters
Otterly Lite or Standard. Low cost, unlimited seats, and you will learn what clients actually ask for before spending real money.
Agency with many mid-sized clients and client-ready reporting
Peec if the project caps work out, or its agency plan if the numbers there suit you. Otterly Standard or Premium if unlimited workspaces matter more than interface polish. Run both on the same ten prompts for a week and see which output you would rather send a client.
Lean team that needs output, not just charts
Slate. If you have one to three people covering content and SEO, a tool that turns citation gaps into shipped pages can be worth more than a prettier dashboard. If you already have a content team, you are overpaying.
Alternatives worth a look
The field is crowded. If none of the three fits, these are the ones I would check next.
Promptwatch goes beyond tracking: it combines real-UI prompt tracking, IP-verified AI crawler logs and a Content Agent that writes and publishes to Webflow, Framer or WordPress. Agency plans start at $199/mo (Kick-off) with unlimited projects and 10 seats, which is a notably different structure from per-project caps.
Rankability and Goodie are built around agencies specifically.
Profound is the enterprise option, and ZipTie is worth a look if browser-level accuracy matters to you.
For a wider scan of the category, the GEO software directory lists far more options than any single roundup.
Questions to ask before you sign
- What happens to my project or workspace count when I add the tenth client?
- Which engines are in the base price, and what do Gemini, AI Mode and Claude cost on top?
- Is white-label reporting included, and in which plan?
- Can I tell, per prompt, which engine and country produced the result?
- For Slate: how many credits does a typical month of my content workload burn?
Bottom line
Pick Otterly for the lowest-risk start and many-workspace setups, Peec for clean client-facing dashboards and broader model choice, and Slate only if you want the platform to produce content as well as measure it. Confirm current prices at each vendor's pricing page, since the figures shown here come from scraped pages and several had promo or ambiguous views.
