Key takeaways
- Client work needs more than a dashboard: white-label reporting, per-client pricing that survives small retainers, and a way to ship fixes, not just log mentions.
- Goodie AI is priced per brand workspace, with Core at $399/mo per the third-party sources we found, so ten clients gets expensive fast. Its own blog says plans start at $295, so verify on higoodie.com/pricing.
- Slate positions itself as a content operations platform (from $199/mo, a vendor claim) and fits content-heavy B2B SaaS teams. We could not verify its agency features or white-label options.
- Promptwatch has the broadest documented agency stack (white-label portal, scheduled PDFs, Slack agents per client, crawler logs, Content Agent), with agency plans from $199/mo. The vendor-published comparisons are biased, so run your own trial.
- Whichever you pick, test it on two real client accounts before committing.
What "ready for client work" actually means
A tool can be great for an in-house marketer and still be a headache for an agency. I have seen teams buy a visibility platform, build one beautiful dashboard, and then discover they cannot hand it to a client without exposing the vendor's branding or paying for another workspace.
So before comparing features, here is the checklist I would use:
- Per-client cost. Does each client need a full plan, or is there a pooled allowance?
- Reporting. White-label PDFs, scheduled sends, a client portal.
- Engine coverage. Which AI models are included on the plan you will really buy, not the enterprise tier.
- Execution. Can the tool help produce and publish the fix, or does it stop at a chart?
- Proof. Does it connect visibility to traffic and conversions, so you can defend the retainer?
- Pitching. Can you run prospects through it before they sign?
A quick note on sourcing. Most of what is public about these three comes from vendor blogs and from competitors writing comparison posts. I flag who is saying what below, and where I could not verify something, I say so.
The three platforms at a glance
| Slate | Goodie AI | Promptwatch | |
|---|---|---|---|
| Positioning | AI-search-first content operations | AEO platform with optimization workflows | End-to-end AI visibility and GEO platform |
| Entry price | From $199/mo (vendor claim) | $399/mo Core (third-party), $295 per Goodie's blog | Free Explore tier; Essential $95/mo |
| Agency pricing | Not verified | Agency Growth $275/mo plus a full brand plan per client workspace | Kick-off $199, Growth $399, Scale $799 with unlimited projects |
| White-label reporting | Not verified | Not described on pricing page | White-label workspace, client portal, scheduled PDFs |
| Content execution | Core strength | 50 to 100 optimizations a month by plan | Content Agent with Webflow, Framer, WordPress publishing |
| Crawler logs | Not verified | Not documented in our sources | IP-verified AI crawler logs |
| Best fit | B2B SaaS and content-led teams | Content-led SaaS, publishers | Agencies needing monitoring plus execution plus attribution |
Always confirm current numbers on each vendor's pricing page. These move monthly.
Slate
Slate describes itself as an AI-native content marketing and GEO platform. It monitors AI search visibility, automates content creation and refreshes pages at scale. Its own blog says it starts at $199/mo and is strongest for B2B SaaS and content-led teams, which is a vendor claim worth treating as such.
A competitor, Analyze AI, positions Slate as a fit for agencies scaling content production and SEO workflows. That is also a rival's view, but it matches the product shape: Slate is built around producing and refreshing content, with tracking feeding that loop.
Where Slate looks strong
If your agency's service is mostly content, and your clients want volume, a content-operations-first tool makes sense. Tracking and production live in one place, which cuts the handoff between the person who spots the gap and the person who writes the page.
What I could not verify
This is the gap that matters for this article. I did not find public detail on Slate's agency features, white-label options, or prompt and engine limits. That does not mean they are missing. It means you should ask directly, and I would not sign anything until you have seen a client-ready report produced in the product.
Questions to put to Slate's sales team:
- Is there a multi-client workspace, and how is it priced?
- Can reports carry our branding?
- How many prompts and which engines are included at the $199 level?
- Does it read AI crawler logs, or only track responses?
Goodie AI
Goodie AI is an answer engine optimization platform that bundles monitoring with optimization workflows. GTMonly describes it as combining AEO, traditional SEO and competitive ads intelligence, and recommends it for content-led SaaS companies, publishers and brands investing in AI-driven content discoverability.
Pricing, and the discrepancy you need to resolve
Third-party sources (ContentMonk, citing Goodie's pricing page) list these tiers:
| Plan | Price | Models | Prompts | Optimizations/mo | Seats |
|---|---|---|---|---|---|
| Core | $399/mo | 5 | 120 | 50 | 5 |
| Pro | $999/mo | 8 | 250 | 100 | Unlimited |
| Enterprise | Custom | Up to 13 | 500+ | Custom | Custom, SOC 2, strategist |
Goodie's own blog says plans start at $295/mo and covers 11+ engines including Alexa for shopping. That conflicts with the $399 figure. Plans and packaging change, so check higoodie.com/pricing yourself before you build a proposal around either number.
Two more details from the third-party reviews. Gemini only appears from Pro, and Claude, Grok, Meta AI and DeepSeek need an Enterprise contract. And Goodie has no Google rank tracking.
The agency math
Goodie's Agency Growth plan is $275/mo and includes 10 pitch workspaces a month, MCP access and unlimited seats. But each client workspace is a full brand plan, with Core at $399 as the lowest. Moistur, which sells a competing product and so has its own angle, calculates ten clients at roughly $4,265/mo at annual-billing rates. White-label reporting is not described on the pricing page.
That is the pattern to watch. Per-client-workspace pricing is fine when you manage three large accounts. It is painful when you have eight small retainers at $1,500 a month, because the tool cost eats a big slice of each one.
Promptwatch
Promptwatch is an end-to-end AI search visibility and GEO platform. It tracks real interfaces (ChatGPT, Google AI Overviews, AI Mode, Gemini, Perplexity, Copilot and others), then goes further than monitoring: crawler logs, visitor analytics, a content gap analysis, and a Content Agent that plans, writes and publishes.
Agency plans
| Plan | Price | Responses/mo | Notes |
|---|---|---|---|
| Kick-off | $199/mo | 10,000 | Unlimited projects, pitch projects and prompts, 10 seats |
| Growth | $399/mo | 25,000 | Same structure |
| Scale | $799/mo | 65,000 | Most popular agency tier |
The structural difference from Goodie is that agency plans use a pooled response allowance across unlimited projects, instead of a full plan per client. Compare the same ten-client portfolio: one Growth or Scale subscription versus roughly $4,000+ in per-workspace fees. Your usage still matters, because a 10-client account running hundreds of prompts will burn through responses, so estimate your volume before assuming the cheapest tier fits.
What it documents for client delivery
Per Promptwatch's own materials, you get a white-label workspace and client portal, scheduled PDF reports, Excel and CSV exports, and a Slack agent mapped to client projects. Agent Chat can build dashboards and PDF reports on request. Those are vendor claims, so ask for a demo using your own client data.
On the proof side, Promptwatch measures AI-referred visitors on a first-party script rather than relying only on GA4, and its IP-verified crawler logs show which AI bots hit a client's pages and whether they hit errors. For an agency that has to answer "is this actually bringing us customers?", that is the strongest part of the stack. TreeHouse, the company behind Pararius, reported AI search reaching about 25% of organic conversions after fixing crawler access and publishing proprietary data. Crisp reported 2x higher conversion from AI traffic.
A caveat on the bias. The comparison page where Promptwatch scores itself best was written by Promptwatch. Its claim to be the only platform clearing all six capability areas is the vendor's own scoring. The capability list is useful as a checklist anyway.
Where it is not the best fit
Some reviewers find it heavier than a marketer-first dashboard tool. GTMonly calls it more infrastructure-oriented and potentially too technical for teams that just want executive reporting. Also note that third-party listings of its engine coverage vary, so confirm which models are on the exact plan you would buy.
Head-to-head on what agencies care about
| Criterion | Slate | Goodie AI | Promptwatch |
|---|---|---|---|
| Cost for 10 clients | Unknown, ask | About $4,265/mo (third-party estimate) | Agency plan from $199 to $799/mo, depending on volume |
| Pitch workspaces | Unknown | 10 per month on Agency Growth | Pitch projects included |
| White-label | Unverified | Not on pricing page | Documented |
| Content production | Core focus | Optimization quotas | Content Agent, CMS publishing |
| AI crawler logs | Unverified | Not documented | Yes, IP-verified |
| Traffic attribution | Unverified | Unverified | First-party visitor analytics |
| Reddit, YouTube, LinkedIn tracking | Unverified | Unverified | Dedicated reports |
The repeated "unverified" cells are the honest finding. Public documentation for Slate and Goodie is thinner on the agency specifics than the vendors' marketing suggests, so the burden is on you to ask.
Why the evidence layer matters for client reporting
Clients will ask why a number moved. Promptwatch Data shows how different the engines behave. In its analysis of average sources per response (based on 26B+ data points from real UIs, published Sept 2025), ChatGPT cited about 5 sources per web-search answer, while Google AI Overviews and Perplexity cited about 10. More recently, Promptwatch's data shows almost half of ChatGPT responses cite 10 or more unique domains for Sep 28 to Oct 4, 2026. Those numbers change month to month, so treat them as snapshots.
The practical point: a single blended visibility score hides engine differences. Whatever tool you choose, make sure it breaks results out by engine, country and prompt, so you can explain a drop instead of shrugging.
How to run a one-week bake-off
Don't decide from a demo. Run this instead.
- Pick two clients, one large and one small, with different languages or markets if you have them.
- Load the same 30 to 50 prompts into each tool.
- Check that engines and countries match your clients' real audiences, not the enterprise tier.
- Produce one client report in each tool, with branding, and send it to a colleague who has not seen the tools. Can they follow it?
- Ask each tool for one concrete action on a client page, then see who ships it, you or the platform.
- Calculate the all-in monthly cost for your full client list, including pitch workspaces.
The free-trial landscape helps here. Goodie offers a 7-day trial on Core, and Promptwatch offers a 7-day trial on monthly Essential and the agency Kick-off and Growth plans. Confirm Slate's trial terms directly.
Which one should you pick?
Pick Slate if your agency sells content production to B2B SaaS clients and you want tracking inside the same workflow as drafting and refreshing. Get its agency pricing and reporting in writing first.
Pick Goodie AI if you have a small number of high-value brands, want built-in optimization quotas, and the per-brand pricing fits your retainers. Resolve the $295 versus $399 question before quoting clients.
Pick Promptwatch if you manage many clients and need pooled agency pricing, documented white-label reporting, crawler logs and conversion attribution, and you want the platform to help publish the fix. It is the one I would shortlist first for a multi-client agency, with the caveat that you should test it against your own data rather than trust its self-published scoring.
If none of these fit, the GEO software directory at bestgeosoftware.com lists a wider set of options. Cheaper agency-oriented alternatives mentioned in the research include Peec (about $495/mo for 10 clients), Otterly ($489 for 10 clients) and RankPrompt Agency ($119/mo annual with white-label), all per third-party sources.
Rank Prompt
Promptwatch is also running a live session on October 22 titled "Auditing & Scaling AI Search for Clients", which is a low-effort way to see its agency workflow before paying for anything.
The deciding test is simple: can you hand a client a branded report this week, and can the tool show what changed after you fixed something? If the answer to either is a promise instead of a demo, keep looking.
