Key takeaways
- Otterly.AI and Goodie AI are the lowest-cost entry points, but both are monitoring-only — they show you data without helping you act on it.
- Peec AI sits in the mid-tier with smart suggestions, but still lacks content generation and deep traffic attribution.
- Promptwatch is the only platform here that closes the full loop: find visibility gaps, generate content to fix them, and track the results — all in one place.
- If you're just starting out and want free or near-free monitoring, Goodie AI or Otterly.AI's entry plan work. But once you want to actually improve your AI visibility, you'll outgrow them quickly.
The AI search landscape shifted fast. In 2024, tracking whether ChatGPT mentioned your brand was a curiosity. By 2026, it's a budget line item for most marketing teams. The problem is that the tool market exploded alongside that shift, and now there are dozens of platforms all claiming to help you "win at AI search" — many of which do roughly the same thing at wildly different price points.
This guide focuses on four tools that come up constantly in budget-conscious conversations: Goodie AI, Otterly.AI, Peec AI, and Promptwatch. They're not all in the same category, and that's kind of the point. Understanding what separates them is more useful than a generic feature checklist.
What these tools actually do (and what they don't)
Before comparing them, it's worth being clear about the two fundamentally different things AI visibility tools can do:
- Monitor: Track how often your brand appears in AI-generated responses, which models mention you, and how you compare to competitors.
- Optimize: Identify why you're not appearing, generate content to fix it, and measure whether that content actually improved your visibility.
Most tools in this space do #1. Very few do #2. That distinction matters enormously when you're deciding what to pay.
Goodie AI
Goodie AI (higoodie.com) is one of the more accessible entry points in the category. It's positioned as a lightweight monitoring tool — you set up your brand, define some prompts, and it tells you whether you're appearing in AI responses.
What it does well is lowering the barrier to entry. If you've never tracked AI visibility before and want to see what the data looks like without committing to a paid plan, Goodie AI is a reasonable starting point.
The limitations show up quickly, though. There's no content gap analysis, no built-in content generation, no crawler log data, and no traffic attribution. You can see that you're not appearing for a prompt — but the tool won't tell you why, and it won't help you fix it. For teams that just want a basic pulse check, that's fine. For anyone who wants to move the needle, it's not enough.
Otterly.AI
Otterly.AI is probably the most-cited "affordable" option in the AI visibility space, and for good reason. Its Lite plan starts at $29/month for 10 prompts across four AI engines (ChatGPT, Google AI Overviews, Perplexity, and Gemini). That's genuinely low for this category.
Otterly.AI
The platform tracks brand mentions, share of voice, and citation rates across those engines. The interface is clean and the setup is fast — you can be monitoring within minutes of signing up. No credit card is required for the free trial, which is a nice touch.
Where Otterly.AI runs into the same wall as Goodie AI is on the optimization side. It's a monitoring dashboard. It shows you the data. What you do with that data is entirely up to you. There's no answer gap analysis, no content recommendations, and no way to generate content directly from the platform. If your brand isn't appearing for a prompt, Otterly.AI will confirm that — but it won't tell you what to write to fix it.
For small teams or solo marketers who just want visibility data at a low cost, Otterly.AI is a solid choice. For anyone who needs to actually improve their AI search presence, the monitoring-only model eventually becomes a ceiling.
Peec AI
Peec AI sits a step above the entry-level tools. Its Starter plan runs around €85/month for 50 prompts across three AI engines. That's a meaningful jump from Otterly.AI's $29 entry point, but Peec AI does offer more — particularly around suggestions and recommendations.
The platform includes some smart prompting features that help you understand what topics you're missing and where competitors are outperforming you. It's closer to an optimization tool than Otterly.AI or Goodie AI, but it still doesn't include built-in content generation. You get the insight; you still need to act on it yourself.
Peec AI also covers fewer AI engines than some competitors at its price point, which is worth factoring in if you care about tracking across Claude, DeepSeek, or Grok in addition to the major three.
For teams that want more than raw monitoring data but aren't ready for a full-featured platform, Peec AI is a reasonable middle ground. Just go in knowing you'll still need a separate content workflow to act on what you find.
Promptwatch
Promptwatch is a different kind of tool. Where the others are monitoring dashboards, Promptwatch is built around an action loop: find the gaps, create content to fill them, track the results.
The Essential plan starts at $99/month (1 site, 50 prompts, 5 AI-written articles per month). That's more than Otterly.AI's entry price, but you're getting something fundamentally different: not just data about where you're invisible, but a built-in workflow to fix it.
The Answer Gap Analysis shows you exactly which prompts your competitors are appearing for that you're not — with the specific topics and angles that AI models want to see covered on your site. From there, the built-in AI writing agent generates articles, listicles, and comparisons grounded in real citation data (880M+ citations analyzed). This isn't generic content; it's engineered to get cited by ChatGPT, Claude, Perplexity, and other models.
Promptwatch also covers 10 AI models (ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews, Google AI Mode, Grok, DeepSeek, Copilot, and Meta/Llama), which is the widest coverage in this comparison. The Professional plan ($249/month) adds AI crawler logs — real-time data on which pages AI crawlers are reading, how often they return, and what errors they encounter. That's a feature most competitors don't offer at all.
Traffic attribution is another differentiator. Promptwatch connects AI visibility to actual revenue through a code snippet, Google Search Console integration, or server log analysis. You can see whether the content you published actually drove visits and conversions — not just whether it got cited.
The platform is used by 6,700+ brands including Booking.com and Center Parcs, and its data has been cited in the Wall Street Journal and Axios.

Which tool should you actually use?
The honest answer depends on where you are in your AI visibility journey.
If you've never tracked AI visibility before and want to see what the data looks like, start with Otterly.AI. The $29/month entry point is low enough to justify as a learning exercise, and the interface is clean enough that you'll understand the data quickly.
If you want something free to dip your toes in, Goodie AI works for that initial pulse check.
If you're past the "what is this" phase and want smarter suggestions about where to focus, Peec AI is worth a look — especially if you're already running a content operation and just need better direction.
But if you're at the point where you need to actually move your AI visibility numbers, monitoring-only tools will frustrate you. You'll see the gap clearly and have no built-in way to close it. That's where Promptwatch earns its price difference. The combination of gap analysis, content generation, and result tracking means you're not just watching the problem — you're fixing it.
The Professional plan at $249/month also adds crawler logs, which is genuinely useful for diagnosing why AI models aren't citing your pages. If a crawler is hitting your site and encountering errors, you'll know. Most tools in this space don't surface that data at all.
A note on the "free" tier question
Several people searching for this comparison are specifically looking for free or near-free options. That's a legitimate constraint. Here's the realistic picture:
- Goodie AI has the lowest barrier to entry and is worth trying if budget is the primary concern.
- Otterly.AI's $29/month Lite plan is genuinely affordable and gives you real data across four engines.
- Promptwatch offers a free trial, so you can experience the full platform before committing.
The tradeoff is predictable: free and low-cost tools give you monitoring. Optimization costs more because it's doing more. If you're a small brand just starting to think about AI search, the free/cheap tier is fine. If you're a marketing team with revenue targets tied to AI visibility, the ROI math on a full-featured platform tends to work out quickly.
The bigger picture
The AI visibility tool market in 2026 is genuinely crowded. A comparison published by Visiblie in April 2026 tracked pricing across nine platforms and found entry prices ranging from $29/month (Otterly.AI) to custom enterprise pricing. The category is maturing fast, and the gap between monitoring tools and optimization platforms is becoming the defining split.
Goodie AI and Otterly.AI sit firmly in the monitoring camp. Peec AI is edging toward optimization but hasn't fully crossed over. Promptwatch is the clearest example of a platform that treats monitoring as the starting point, not the end goal.
That framing — monitoring vs. optimization — is probably the most useful lens for evaluating any AI visibility tool in 2026. The question isn't just "does this show me data?" It's "does this help me do something with it?"
