Key takeaways
- Otterly.AI starts at $29/mo -- Promptwatch at $99/mo. If budget is the primary constraint, Otterly wins on entry price. But the gap narrows fast at higher tiers.
- Otterly.AI is a monitoring tool. It shows you data about where your brand appears in AI results. Promptwatch is built to act on that data: content gap analysis, AI content generation, and crawler logs are all included.
- Promptwatch tracks 10+ AI models (including Claude, Grok, DeepSeek, Mistral, Meta AI). Otterly.AI focuses on ChatGPT, Perplexity, and Google AI Overviews.
- If you want to know why you're invisible in AI search and fix it, Promptwatch has the tools. If you just want a dashboard to monitor brand mentions, Otterly.AI covers that at a lower price.
- Promptwatch includes AI crawler logs -- real-time data on which AI bots are crawling your site and when. Otterly.AI has no equivalent feature.
- For agencies or teams managing multiple brands, Promptwatch's multi-site architecture and Looker Studio integration are more practical at scale.
Overview
Promptwatch
Promptwatch is an end-to-end GEO (Generative Engine Optimization) platform used by 1,480+ brands and agencies. It tracks how brands appear across 10+ AI search engines, but the real differentiator is what happens after you see the data. Answer gap analysis shows which prompts competitors rank for but you don't. Content Agents generate articles and briefs grounded in real citation and prompt data. Crawler logs show exactly which AI bots are hitting your site and which pages they're reading. The whole platform is built around a loop: find gaps, create content, track results.
Clients include Booking.com, Center Parcs, Duolingo, Typeform, Yelp, and Shutterstock. It's rated 4.7/5 on G2.
Otterly.AI
Otterly.AI is a monitoring-focused AI visibility tool that tracks brand mentions and citations across ChatGPT, Perplexity, and Google AI Overviews. It's positioned as an accessible entry point into AI search monitoring -- the $29/mo Lite plan is one of the lowest price points in the category. The interface is clean, the setup is quick, and for teams that primarily want to watch their brand coverage over time and compare against competitors, it does the job well. Otterly claims 30,000+ marketing pros using the platform, with case studies from brands like Roche, Opera, and Auto1.
What it doesn't do: generate content, analyze crawler behavior, track ChatGPT Shopping, or help you understand why you're missing from AI results.

Head-to-head feature deep-dive
Monitoring and brand tracking
Both tools track brand mentions across AI search engines, but the depth differs. Otterly.AI gives you brand coverage over time, average brand position, mention counts, and competitor comparisons. The UI is clean and the data is easy to read. For a marketing manager who wants a weekly check on "how often does our brand come up in ChatGPT vs competitors," Otterly delivers that without friction.
Promptwatch covers the same ground but with more granularity. You get page-level citation tracking (which specific URLs are being cited, not just the domain), prompt-level data showing exactly which queries trigger your brand, and competitor heatmaps that show who's winning for each prompt across each AI model. The difference is resolution -- Otterly shows you the headline number, Promptwatch shows you the underlying mechanics.
Verdict: Otterly.AI is easier to get started with. Promptwatch gives you more to work with.
AI model coverage
| AI model | Promptwatch | Otterly.AI |
|---|---|---|
| ChatGPT / OpenAI | Yes | Yes |
| Perplexity | Yes | Yes |
| Google AI Overviews | Yes | Yes |
| Google AI Mode | Yes | No |
| Gemini | Yes | No |
| Claude | Yes | No |
| Grok | Yes | No |
| DeepSeek | Yes | No |
| Meta AI / Llama | Yes | No |
| Mistral | Yes | No |
| Copilot | Yes | No |
This is one of the starkest differences. Otterly.AI covers three models. Promptwatch covers ten. If you care about how your brand appears in Claude, Gemini, or Grok -- which together represent a meaningful and growing share of AI search traffic -- Otterly.AI simply can't tell you.
Verdict: Promptwatch wins decisively on model coverage.
Content optimization and gap analysis
This is where the two tools diverge most sharply. Otterly.AI is a monitoring tool. It shows you data. What you do with that data is up to you.
Promptwatch has an entire layer built on top of monitoring: Answer Gap Analysis identifies the specific prompts where competitors are visible but you're not. Content Agents then generate articles, listicles, comparison pages, and content briefs using real prompt data, citation patterns, prompt volumes, and competitor analysis. Agent analytics tracks the timeline from when you publish a page to when AI crawlers find it and start citing it.
For a team that wants to actually improve their AI visibility -- not just measure it -- this matters a lot. Monitoring tells you the problem. Optimization tools help you fix it.
Verdict: Promptwatch is the only option here. Otterly.AI has no content optimization features.
AI crawler logs and technical insights
Promptwatch's crawler log feature is genuinely unusual in this category. It shows real-time logs of AI crawlers (ChatGPT, Claude, Perplexity, etc.) hitting your website -- which pages they read, how often they return, any errors they encounter, and when a crawled page moves to being actively cited. You can connect it through Cloudflare, Fastly, Vercel, server logs, Google Search Console, or a tracking snippet.
This is useful for diagnosing why certain pages aren't being cited despite being well-written. Maybe the AI crawler is hitting a 404. Maybe it's crawling the page but not citing it because the content structure doesn't match what the model wants. Crawler logs surface these issues.
Otterly.AI has no equivalent. There's no way to see how AI bots interact with your site.
Verdict: Promptwatch only.
Pricing and value
See the full pricing breakdown below, but the short version: Otterly.AI is cheaper at entry level. The $29/mo Lite plan is genuinely accessible for small teams or individuals who just want basic monitoring. Promptwatch's $99/mo Essential plan includes more features but is a bigger commitment.
At the mid-tier, the gap narrows. Otterly's Standard at $189/mo vs Promptwatch's Professional at $249/mo -- a $60/mo difference, but Promptwatch at that tier includes crawler logs, content generation (15 articles/mo), state/city tracking, and traffic attribution. Otterly's Standard plan is primarily more prompts and more brands.
For teams that need content generation and technical insights, Promptwatch's Professional plan is the better value even at the higher price. For teams that only need monitoring, Otterly is cheaper.
Verdict: Otterly.AI wins on price. Promptwatch wins on value per dollar at mid-tier and above.
Ease of use and setup
Otterly.AI is genuinely quick to set up. You add your brand, add competitor brands, pick your prompts, and you're tracking within minutes. The interface is straightforward and doesn't require much onboarding.
Promptwatch has more surface area -- more features means more to configure. The crawler log setup requires a website integration (Cloudflare, Vercel, etc.), which adds some technical overhead. That said, the core monitoring setup is also fast, and the platform has a free trial that lets you track 50 prompts before committing.
Verdict: Otterly.AI is simpler to get started with. Promptwatch has a steeper learning curve but more to learn.
Agency and enterprise features
Promptwatch has a dedicated agency offering with custom pricing, multi-site management, Looker Studio integration, and an API for custom workflows. It's used by agencies like Monks, IO Digital, and Adwise. The platform supports white-label reporting and multi-client dashboards.
Otterly.AI supports tracking multiple brands, which works for agencies at a basic level, but there's no dedicated agency tier, no Looker Studio integration, and limited API access. It's more suited to in-house marketing teams than agencies managing multiple clients.
Verdict: Promptwatch is the stronger choice for agencies.
Pricing comparison
| Plan | Promptwatch | Otterly.AI |
|---|---|---|
| Free / trial | Free trial (50 prompts) | Free trial |
| Entry paid | Essential: $99/mo (1 site, 50 prompts, 5 articles/mo) | Lite: $29/mo |
| Mid tier | Professional: $249/mo (2 sites, 150 prompts, 15 articles/mo, crawler logs) | Standard: $189/mo |
| Higher tier | Business: $579/mo (5 sites, 350 prompts, 30 articles/mo) | Not publicly listed |
| Agency / Enterprise | Custom pricing | Not available |
| Annual discount | Yes | Not confirmed |
The $29/mo Lite plan from Otterly.AI is hard to beat for pure affordability. But it's worth being clear about what you're getting: basic monitoring across a limited set of models, no content tools, no crawler data. For a solo marketer or small startup that just wants to know if their brand is showing up in ChatGPT, that might be enough.
For anyone who wants to actually move the needle on AI visibility -- create content, fix crawl issues, track which pages are driving citations -- the Promptwatch Professional plan at $249/mo is where the real work happens.

Final verdict
Otterly.AI is a solid monitoring tool at a price that's hard to argue with. If you want a lightweight way to check whether your brand shows up in ChatGPT and Perplexity, it works. But it stops there.
Promptwatch is built for teams that want to do something about what they find. The content generation, crawler logs, answer gap analysis, and 10-model coverage aren't just nice-to-haves -- they're the difference between knowing you have an AI visibility problem and actually fixing it. For any team serious about GEO in 2026, Promptwatch is the more complete platform.
If you're comparing the two and budget isn't the deciding factor, Promptwatch is the stronger choice. If $29/mo is what you can spend right now, Otterly.AI gets you started -- just know you'll likely outgrow it.
