Mentions.so entered the AI visibility space with a simple promise: track how AI chatbots mention your brand. It works -- you can monitor ChatGPT, Claude, Perplexity, and other models, see sentiment scores, and compare yourself to competitors. The free tier (25 prompts, 3 LLMs) is generous for testing, and the $249/mo paid plan covers most use cases.
But here's the problem: Mentions.so shows you the data, then leaves you stuck. You see that competitors are mentioned more often. You notice your brand isn't showing up for key prompts. You track sentiment trends. Now what? The platform doesn't tell you which content is missing, doesn't help you create it, and doesn't show you how AI crawlers interact with your site. You're paying for a dashboard that points out problems without solving them.
That's why people look for alternatives. Some want deeper analytics. Others need content optimization tools. Many want to close the loop from "we're invisible" to "we fixed it" without switching between five different platforms.
Promptwatch
Promptwatch is the only AI visibility platform built around taking action, not just watching numbers. It's rated as a "Leader" across all categories in a 2026 comparison of 12 GEO platforms, and the reason is simple: it shows you what's missing, then helps you fix it.
The core difference is the action loop. Answer Gap Analysis shows exactly which prompts competitors rank for but you don't -- the specific topics, angles, and questions AI models want answers to but can't find on your site. You're not guessing what to write. You're seeing the actual content gaps that cost you visibility.
Then the built-in AI writing agent generates articles, listicles, and comparisons grounded in real citation data (880M+ citations analyzed), prompt volumes, persona targeting, and competitor analysis. This isn't generic SEO filler. It's content engineered to get cited by ChatGPT, Claude, Perplexity, and other AI models. You go from "we're invisible for this prompt" to "here's the article that will fix it" in one platform.
Finally, page-level tracking shows exactly which pages AI models cite, how often, and by which models. Close the loop with traffic attribution (code snippet, GSC integration, or server log analysis) to connect visibility to actual revenue.
Most Mentions.so competitors stop at step one. Promptwatch is the only platform that completes the cycle: find gaps, generate content, track results.
Additional capabilities that support the action loop:
- AI Crawler Logs: Real-time logs of ChatGPT, Claude, Perplexity crawlers hitting your site -- which pages they read, errors they encounter, how often they return. Fix indexing issues before they cost you citations. Mentions.so doesn't have this.
- Prompt Intelligence: Volume estimates and difficulty scores for each prompt, plus query fan-outs that show how one prompt branches into sub-queries. Prioritize high-value, winnable prompts instead of guessing.
- Citation & Source Analysis: See exactly which pages, Reddit threads, YouTube videos, and domains AI models cite. Know where to publish and what to optimize.
- Reddit & YouTube Insights: Surface discussions that directly influence AI recommendations -- a channel most competitors ignore entirely.
- ChatGPT Shopping Tracking: Monitor when your brand appears in ChatGPT's product recommendations and shopping carousels.
- Competitor Heatmaps: Compare your AI visibility vs competitors across LLMs. See who's winning for each prompt and why.
- Multi-language & Multi-region: Monitor AI responses in any language, from any country, with customizable personas that match how your actual customers prompt.
Pricing: Essential $99/mo (1 site, 50 prompts, 5 articles), Professional $249/mo (2 sites, 150 prompts, 15 articles, crawler logs, state/city tracking), Business $579/mo (5 sites, 350 prompts, 30 articles). Free trial available.
Best for: Marketing teams, SEO teams, and agencies that want to actually improve AI visibility, not just track it. If you're tired of monitoring-only dashboards that show problems without solving them, Promptwatch is the answer.
Otterly.AI
Otterly.AI positions itself as the affordable entry point to AI visibility tracking. At $29/mo for the Lite plan (15 prompts), it's the cheapest option on this list. The Standard plan ($189/mo, 100 prompts) covers most use cases, and Premium pricing is custom.
The platform monitors ChatGPT, Perplexity, Google AI Overviews, AI Mode, Gemini, and Copilot. You get brand mention tracking, share of voice comparisons, and sentiment analysis. The GEO Audit tool analyzes 25+ on-page factors to reveal what's holding your site back from earning citations -- a useful feature that Mentions.so lacks.
Otterly.AI also includes AI keyword research to discover the prompts your audience is asking, which helps you prioritize what to track. The interface is clean and the 14-day free trial (no credit card required) makes it easy to test.
But here's the catch: Otterly.AI is monitoring-focused. You get visibility scores, citation tracking, and audit recommendations, but no content generation, no crawler logs, no Reddit/YouTube tracking, and no traffic attribution. It tells you what's wrong and gives you a checklist, but you're on your own to fix it.
Pricing: Lite $29/mo (15 prompts, 3 LLMs), Standard $189/mo (100 prompts, all models), Premium custom. 14-day free trial.
Best for: Startups and small teams testing AI visibility tracking on a budget. Good for understanding the basics without heavy investment. Not ideal if you need advanced optimization tools or want to close the loop from tracking to action.
Peec AI
Peec AI is a European-based platform (pricing in euros) with strong multi-language and multi-country support. Starting at €89/mo for the Starter plan (25 prompts, 3 countries), it's positioned between Otterly.AI and Promptwatch in terms of price and features.
The platform tracks ChatGPT, Perplexity, Claude, and Gemini. You get visibility scores, position tracking, sentiment analysis, and competitor benchmarking. The interface is polished and the smart prompt suggestions help you discover new queries to monitor.
Peec AI's standout feature is multi-language tracking across 10 countries (Professional plan, €199/mo, 75 prompts). If you're a European brand or operate in multiple markets, this is valuable. Most competitors (including Mentions.so) charge extra for multi-region tracking or don't support it well.
The weakness: Peec AI is monitoring-only. No content generation, no crawler logs, no Reddit/YouTube insights, no traffic attribution. You see the data, you get some suggestions, but you're building the solution yourself.
Pricing: Starter €89/mo (25 prompts, 3 countries), Professional €199/mo (75 prompts, 10 countries, all models), Business custom. Free trial available.
Best for: European brands and agencies tracking AI visibility across multiple languages and countries. Good for teams that need multi-region monitoring but can handle content optimization separately.
AthenaHQ
AthenaHQ is a straightforward AI search monitoring tool focused on brand presence tracking. It monitors major AI models (ChatGPT, Claude, Gemini, Perplexity) and provides visibility tracking and citation analysis.
The platform is clean and easy to use. You set up prompts, AthenaHQ tracks them across models, and you get reports on when and how your brand is mentioned. The citation analysis shows which sources AI models reference, which helps you understand the competitive landscape.
But AthenaHQ is bare-bones compared to Promptwatch or even Otterly.AI. No content generation, no crawler logs, no Reddit/YouTube tracking, no GEO audit features, no traffic attribution. It's a monitoring dashboard, period. You see the data, you export it, you figure out what to do next.
Pricing isn't publicly listed, which usually means it's higher than competitors who advertise their rates. For a monitoring-only tool, that's a tough sell when Otterly.AI starts at $29/mo and Promptwatch gives you the full optimization suite at $99/mo.
Best for: Teams that only need basic monitoring and already have content/SEO workflows in place. Not recommended if you want optimization tools or actionable insights.
Profound
Profound markets itself as an enterprise AI visibility solution. The website is currently a domain-for-sale page ($4,988), which suggests the product may be discontinued or rebranding. This is a red flag.
Based on historical data, Profound offered comprehensive monitoring across AI models with strong feature sets, but at higher price points than competitors. It included citation tracking, sentiment analysis, and competitor benchmarking, but lacked Reddit tracking and ChatGPT Shopping monitoring.
The domain status makes it impossible to recommend. If you're evaluating Profound, confirm the product is still active before investing time in a demo.
Best for: No recommendation until the product status is clarified.
Search Party
Search Party
Search Party is an AI visibility and sentiment tracking platform starting at $95/mo. It monitors ChatGPT, Perplexity, Claude, and Gemini, tracking how brands appear in AI-generated answers.
The platform is agency-oriented, which means it's built for teams managing multiple clients. You get brand mention tracking, sentiment analysis, and citation monitoring. The interface is designed for reporting to stakeholders.
The problem: Search Party is monitoring-focused with limited prompt metrics and no content gap analysis. You see what AI says about your brand, you track sentiment over time, but you don't get the tools to improve it. No content generation, no crawler logs, no Reddit/YouTube insights.
At $95/mo, it's more expensive than Otterly.AI ($29/mo) and only slightly cheaper than Promptwatch ($99/mo), which offers far more features. The value proposition is unclear unless you specifically need the agency-oriented reporting features.
Best for: Agencies managing multiple clients who need clean reporting dashboards. Not ideal for brands that want to actively improve their AI visibility.
Authoritas AI Tracker
Authoritas combines AI search monitoring with traditional SEO tools. The AI Search Platform starts free (50 credits) and scales to Enterprise at £1,125/mo (42,000 credits). The SEO Platform is separate: Essential £99/mo, Advanced £399/mo, Expert $799/mo.
The platform monitors ChatGPT, Perplexity, Claude, Gemini, DeepSeek, Google AI Overviews, and Bing AI. You get citation tracking, sentiment analysis, and competitor benchmarking. The integration with traditional SEO tools (rank tracking, backlink analysis, technical audits) is the main differentiator.
Authoritas is built for eCommerce brands, publishers, and agencies managing competitive niches. If you're already using Authoritas for SEO and want to add AI tracking, this makes sense. If you're starting fresh, the credit-based pricing model is confusing and the combined cost of AI + SEO platforms is high.
The AI tracking features are solid but not exceptional. No content generation, no Reddit/YouTube insights, no traffic attribution. It's monitoring plus traditional SEO, not a true optimization platform.
Pricing: AI Search Platform: Free (50 credits), P1 £90/mo (2,000 credits), P2 £225/mo (6,000 credits), P3 £495/mo (15,000 credits), Enterprise £1,125/mo (42,000 credits). SEO Platform separate.
Best for: Existing Authoritas customers who want to add AI tracking. Not recommended if you're looking for a dedicated AI visibility platform with optimization tools.
LLM Pulse
LLM Pulse is a straightforward AI search visibility tracker starting at €49/mo (Starter: 40 prompts, 5 models). The Growth plan (€99/mo, 100 prompts) and Scale plan (€299/mo, 300 prompts) cover most use cases.
The platform monitors ChatGPT, Perplexity, Gemini, Google AI Mode, and AI Overviews. You get visibility scores, citation rate tracking, sentiment analysis, and share of voice comparisons. The interface is clean and the weekly prompt monitoring keeps you updated without overwhelming you with data.
LLM Pulse also includes AI-powered content recommendations to improve how you appear in LLM responses, which is more than most monitoring-only tools offer. But the recommendations are basic compared to Promptwatch's Answer Gap Analysis and AI writing agent.
The 14-day free trial makes it easy to test. The pricing is competitive with Peec AI and cheaper than Authoritas. But you're still missing crawler logs, Reddit/YouTube tracking, traffic attribution, and content generation.
Pricing: Starter €49/mo (40 prompts, 5 models), Growth €99/mo (100 prompts), Scale €299/mo (300 prompts), Enterprise custom. 14-day free trial.
Best for: Teams that want clean, simple AI visibility tracking with basic optimization suggestions. Good for understanding the landscape before investing in a full optimization platform.
Which alternative should you choose?
If you're looking at Mentions.so alternatives, the decision comes down to what you actually need:
Choose Promptwatch if you want to fix your AI visibility, not just track it. The action loop (find gaps, generate content, track results) is the only way to actually improve your rankings in ChatGPT, Claude, and Perplexity. Crawler logs, Reddit/YouTube insights, and traffic attribution close the loop from visibility to revenue. At $99/mo for Essential, it's competitively priced and delivers far more value than monitoring-only tools.
Choose Otterly.AI if you're on a tight budget and only need basic monitoring. At $29/mo, it's the cheapest option that still covers the major AI models. The GEO audit tool is useful. But you're on your own to fix the problems it identifies.
Choose Peec AI if you need multi-language tracking across multiple countries. The €89/mo Starter plan is reasonable, and the Professional plan (€199/mo) supports 10 countries. Good for European brands and agencies.
Choose LLM Pulse if you want straightforward tracking with basic optimization suggestions. At €49/mo, it's affordable and the interface is clean. But you're missing advanced features like crawler logs and content generation.
Avoid AthenaHQ and Search Party unless you have specific needs for their agency-oriented features. Both are monitoring-focused and overpriced compared to alternatives.
Avoid Profound until the product status is clarified. The domain-for-sale page is a red flag.
Consider Authoritas AI Tracker only if you're already using Authoritas for SEO. The combined cost is high and the AI features aren't exceptional.
The honest truth: most Mentions.so alternatives are just different flavors of the same monitoring dashboard. They show you the data, maybe give you some suggestions, then leave you to figure out the rest. Promptwatch is the only platform that actually helps you improve your AI visibility with content gap analysis, AI-generated articles, and crawler logs. If you're serious about ranking in AI search, that's the difference that matters.
