Promptwatch vs Vaylis (2026): Full comparison

Key takeaways

• Vaylis is the cheaper entry point at €49/month vs Promptwatch's $99/month, but the gap closes fast once you need more than basic monitoring.
• Promptwatch is the only one of the two with a built-in AI content generation engine -- it doesn't just show you what's missing, it helps you write the content to fix it.
• Both tools track a similar set of AI models (ChatGPT, Perplexity, Gemini, Claude, Copilot, etc.), but Promptwatch adds DeepSeek, Mistral, and Google AI Mode.
• Promptwatch includes AI crawler logs, which show you exactly which pages ChatGPT and Perplexity are crawling and where they hit errors. Vaylis has no equivalent feature.
• Vaylis is a solid monitoring and benchmarking tool, well-suited for smaller brands or agencies that want clean dashboards without a steep learning curve.
• If your goal is to actually move the needle on AI visibility -- not just watch the numbers -- Promptwatch's action loop (find gaps, generate content, track results) is a meaningful advantage.

Overview

Promptwatch

Promptwatch is an end-to-end AI search visibility platform used by 7,000+ brands including Booking.com, Center Parcs, and ABN AMRO. It tracks how your brand appears across 10+ AI models, identifies content gaps where competitors are visible but you're not, and includes a built-in AI writing agent to create content engineered to get cited. Crawler logs, prompt volume data, Reddit/YouTube citation tracking, and ChatGPT Shopping monitoring round out a feature set that goes well beyond what most monitoring tools offer.

The core pitch: most AI visibility tools show you a dashboard. Promptwatch shows you a dashboard and then helps you do something about it.

Vaylis

Vaylis is a newer AI search optimization platform targeting brands and agencies that want to track and improve their visibility across ChatGPT, Perplexity, Google AI, and other AI-powered search engines. It covers the fundamentals well: competitor benchmarking, citation analysis, visibility scoring, and actionable recommendations. The agency-facing workflow is a particular strength -- the global filter system and multi-company management make it easy to handle multiple clients without getting lost.

Vaylis is more focused than Promptwatch. That's not necessarily a weakness. For teams that want clean, straightforward monitoring without a lot of extra surface area to manage, it's a reasonable choice.

Side-by-side comparison

Head-to-head feature deep-dive

AI model coverage

Both tools cover the major AI search engines your customers are actually using. Promptwatch tracks ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews, Google AI Mode, Copilot, Meta/Llama, DeepSeek, Grok, and Mistral. Vaylis covers ChatGPT, Perplexity, Google AI, Copilot, Claude, Gemini, Meta AI, and Grok.

The practical difference is smaller than the list makes it look -- DeepSeek and Mistral are still niche for most Western brands. But Google AI Mode is a meaningful gap; it's a distinct surface from Google AI Overviews and increasingly important for search visibility.

Verdict: Promptwatch has broader coverage, but Vaylis covers the models that matter most for the majority of brands.

---

Content gap analysis and content generation

This is where the two tools diverge most sharply.

Promptwatch's Answer Gap Analysis identifies specific prompts where your competitors appear in AI responses but you don't. You see the exact questions AI models are answering without citing your brand, along with the content topics your site is missing. Then -- and this is the part Vaylis can't match -- Promptwatch's built-in AI writing agent generates articles, listicles, and comparison pages grounded in real citation data. The content is designed to get cited, not just to rank in traditional search.

Vaylis provides "actionable recommendations" for improving your AI presence, but there's no content creation engine. You get told what to do; you have to go do it yourself elsewhere.

For teams with dedicated content writers, that might be fine. For teams that are already stretched thin, Promptwatch's generation capability is a real time-saver.

Verdict: Promptwatch wins clearly here. Vaylis monitors and advises; Promptwatch monitors, advises, and helps you execute.

---

AI crawler logs

Promptwatch's crawler log feature is genuinely unusual in this space. It shows you real-time logs of AI crawlers (ChatGPT's GPTBot, Perplexity's PerplexityBot, etc.) hitting your website -- which pages they read, how often they return, and where they encounter errors. If an AI model is ignoring your most important pages, you'll see it here and can fix it.

Vaylis has no equivalent. This isn't a minor gap -- understanding how AI engines discover and index your content is foundational to improving your visibility, and most platforms (not just Vaylis) skip it entirely.

Verdict: Promptwatch only. This feature alone is a reason to choose it over Vaylis if technical AI SEO is part of your workflow.

---

Competitor benchmarking and visibility scoring

Both tools do this reasonably well. Vaylis shows a ranked visibility leaderboard comparing your brand against competitors across AI models, with percentage scores and trend indicators. The interface is clean and easy to read -- the kind of thing you'd put in a client report without much editing.

Promptwatch's competitor heatmaps serve a similar purpose, showing who's winning for each prompt and across which LLMs. It goes deeper with prompt-level breakdowns, so you can see not just that a competitor is outperforming you overall, but exactly which questions they're winning.

Verdict: Tie for basic benchmarking. Promptwatch has more granularity at the prompt level; Vaylis has a cleaner presentation for quick overviews.

---

Agency and multi-client support

Vaylis was clearly built with agencies in mind. The global filter system for managing multiple companies is highlighted prominently, and the walkthrough video on their site focuses specifically on agency workflows. The Scale (€289/mo) and Enterprise (€699/mo+) tiers are where multi-client management lives.

Promptwatch has dedicated agency plans with multi-site support, white-label reporting, and Looker Studio integration for custom dashboards. The agency positioning is strong, though the pricing for larger client rosters can add up.

Verdict: Both are viable for agencies. Vaylis may have a slight edge in UX simplicity for non-technical account managers; Promptwatch has more reporting depth and integration options.

---

Traffic attribution

Promptwatch connects AI visibility to actual website traffic through three methods: a JavaScript code snippet, Google Search Console integration, or server log analysis. You can see which AI-driven visits are converting, not just which prompts mention your brand.

Vaylis's website mentions turning "AI answer exposure into qualified traffic and leads" as a goal, but the specific attribution mechanics aren't publicly documented. It's unclear whether there's a comparable traffic attribution layer.

Verdict: Promptwatch has a clear, documented traffic attribution system. Vaylis's approach here is uncertain.

---

Prompt intelligence

Promptwatch assigns volume estimates and difficulty scores to each tracked prompt, and shows "query fan-outs" -- how a single prompt branches into related sub-queries. This helps you prioritize which prompts are worth chasing vs. which are low-traffic dead ends.

Vaylis doesn't publicly document equivalent prompt-level metrics. You can track prompts, but whether you get volume or difficulty data isn't clear from available information.

Verdict: Promptwatch has more sophisticated prompt prioritization tools.

---

Pricing comparison

A few things worth noting on pricing:

Vaylis is meaningfully cheaper at every tier. If you're a small brand or early-stage startup that just wants to know where you stand in AI search, Vaylis's €49/month entry point is hard to argue with.

Promptwatch's pricing reflects what you're getting beyond monitoring. The $249/month Professional plan includes crawler logs and AI content generation -- features that would otherwise require separate tools. If you'd be paying for a content writer and a technical SEO tool anyway, the math changes.

For agencies billing clients, Promptwatch's per-site pricing model is predictable. Vaylis's enterprise tier starts at €699/month, which is competitive for large agency rosters.

Who should pick which tool

Choose Promptwatch if:

• You want to do more than monitor -- you want to actually improve your AI visibility and need tools to help you create the right content
• Technical AI SEO matters to you and you want crawler log data
• You're tracking a complex competitive landscape across multiple prompts and need prompt-level granularity
• You're an agency that needs robust reporting, API access, and traffic attribution to show clients ROI
• You want Reddit and YouTube citation data to understand the full picture of what influences AI recommendations
• You're running an e-commerce brand that needs ChatGPT Shopping tracking

Choose Vaylis if:

• You're a smaller brand or startup that wants solid AI visibility monitoring without a large budget
• You have a content team that can act on recommendations independently -- you don't need the writing tools built in
• You want a clean, simple dashboard that's easy to hand off to non-technical team members or clients
• Agency-style multi-company management at a lower price point is the priority
• You're just getting started with AI search visibility and want to understand the basics before investing in a more complex platform

Final verdict

Vaylis is a competent monitoring tool at a fair price. For brands that are new to AI search visibility or have limited budgets, it covers the essentials without overwhelming you.

But Promptwatch is a different category of product. The gap isn't just features -- it's the underlying philosophy. Vaylis shows you where you stand. Promptwatch shows you where you stand, tells you exactly what's missing, helps you create the content to fix it, and then tracks whether it worked. That full loop is what separates a monitoring dashboard from an optimization platform, and right now Promptwatch is the only tool in this comparison that completes it.

If you're serious about AI search visibility as a revenue channel, Promptwatch is the more defensible long-term investment.
