Otterly.AI vs Airefs (2026): Which AI visibility tool is better?

Key Takeaways

• Airefs is 17% cheaper at entry level ($24/mo vs $29/mo) and includes Reddit monitoring that Otterly.AI lacks entirely
• Otterly.AI covers 6 AI platforms (ChatGPT, Perplexity, Google AI Overviews, AI Mode, Gemini, Copilot) while Airefs focuses primarily on ChatGPT and Perplexity
• Otterly.AI includes a GEO Audit tool that analyzes 25+ on-page factors -- Airefs doesn't have this diagnostic feature
• Airefs shows which specific content shapes AI answers (LinkedIn posts, Reddit threads, YouTube videos) -- Otterly.AI focuses on website citations
• Otterly.AI's Standard plan ($189/mo, 100 prompts) is nearly 4x the price of Airefs Pro ($49/mo, unlimited prompts)
• Both are monitoring-only tools -- neither generates content or helps you fix gaps. For that action loop, tools like Promptwatch complement either option by adding content gap analysis and AI writing capabilities.

Overview

Otterly.AI

Otterly.AI positions itself as the "#1 rated AI search monitoring platform" for tracking brand mentions and website citations across six major AI search engines. It launched in 2024 as one of the early movers in the GEO space and has built a reputation for broad platform coverage and straightforward monitoring dashboards.

The core pitch: see where your brand shows up in ChatGPT, Perplexity, Google AI Overviews, AI Mode, Gemini, and Copilot. Track which websites get cited. Monitor share of voice against competitors. The GEO Audit feature analyzes your site's on-page factors to identify what's holding you back from more citations.

Pricing starts at $29/mo for 15 prompts (Lite), $189/mo for 100 prompts (Standard), and custom pricing for unlimited prompts (Premium). 14-day free trial available.

Airefs

Airefs takes a different angle. Instead of just tracking website citations, it shows you the actual content that shapes AI answers -- the LinkedIn posts, Reddit threads, G2 reviews, YouTube videos, and Quora answers that AI models pull from. The tagline is direct: "Be the recommended brand in ChatGPT by creating content and showing up in the right places."

The platform focuses heavily on ChatGPT and Perplexity, with less emphasis on the broader AI engine landscape. But what it does cover, it covers with more granularity -- you see exactly which Reddit thread or YouTube video influenced the answer, not just that your website was cited.

Pricing is more aggressive: 7-day free trial, then $24/mo (Lite), $49/mo (Pro), $83/mo (Expert), $249/mo (Agency). The Pro plan at $49/mo includes unlimited prompts, which is a sharp contrast to Otterly.AI's $189/mo for 100 prompts.

Side-by-Side Comparison

Platform coverage

Otterly.AI: Six engines, broad but shallow

Otterly.AI monitors ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, Gemini, and Microsoft Copilot. That's solid breadth. If you need to know whether your brand appears across the entire AI search landscape, Otterly.AI gives you that view.

The trade-off: the data for some platforms is less consistent. Google AI Overviews and AI Mode coverage is strong, but Gemini and Copilot tracking can be spotty depending on query type. The platform doesn't break down which specific content sources (Reddit, YouTube, etc.) influenced each answer -- you just see that your website was or wasn't cited.

Airefs: Two engines, deep and specific

Airefs focuses almost exclusively on ChatGPT and Perplexity. It doesn't try to cover Gemini, Copilot, or Google's AI products. But what it does cover, it covers with more granularity.

You see the actual Reddit threads, LinkedIn posts, YouTube videos, and G2 reviews that shaped the answer. This is useful if your goal is to understand where to create content, not just whether your website got cited. The platform explicitly tells you "your brand isn't part of that content" and shows you where competitors are showing up instead.

Verdict: Otterly.AI wins on breadth. Airefs wins on depth and actionability for the platforms it does cover.

Pricing breakdown

The pricing gap is stark. Otterly.AI's Standard plan at $189/mo gets you 100 prompts. Airefs Pro at $49/mo gets you unlimited prompts. That's a 4x price difference for fewer prompts.

Otterly.AI's Lite plan ($29/mo, 15 prompts) is workable for very small brands or agencies testing the waters. But 15 prompts runs out fast if you're tracking multiple product categories or competitor sets.

Airefs' pricing structure is more aggressive across the board. The $24/mo entry point is lower, and the Pro plan at $49/mo with unlimited prompts is the sweet spot for most teams.

Reddit, YouTube, and LinkedIn tracking

This is where the two tools diverge sharply.

Otterly.AI doesn't track Reddit, YouTube, or LinkedIn at all. It focuses on website citations. You see which domains get cited in AI answers, but you don't see the Reddit threads, YouTube videos, or LinkedIn posts that influenced those answers.

This is a real gap. Reddit threads and YouTube videos are major sources for AI models -- especially ChatGPT and Perplexity. If you're not tracking those, you're missing half the story.

Airefs makes this its core value prop. The platform explicitly shows you which Reddit threads, YouTube videos, LinkedIn posts, G2 reviews, and Quora answers shaped the AI response. You can click through to the actual content and see what competitors are saying.

This is actionable. If a competitor's Reddit thread is influencing ChatGPT's answer, you know to either engage in that thread or create your own content on Reddit. Otterly.AI doesn't give you that insight.

GEO Audit and diagnostic tools

Otterly.AI includes a GEO Audit tool that analyzes 25+ on-page factors to identify what's holding your site back from earning more citations. This is useful for diagnosing technical issues -- schema markup, page speed, content structure, etc.

The audit gives you a checklist of strengths and weaknesses. It's not as deep as a full technical SEO audit, but it's a decent starting point for understanding why your site isn't getting cited.

Airefs doesn't have a GEO Audit feature. It shows you where you're visible and where you're not, but it doesn't diagnose why. You're left to figure out the fixes yourself.

Verdict: Otterly.AI wins here. The GEO Audit tool adds diagnostic value that Airefs lacks.

Competitor tracking and share of voice

Both tools let you track competitors and see how your brand stacks up.

Otterly.AI shows share of voice across all six platforms. You can see which competitors get mentioned more often and which websites get cited more frequently. The data is aggregated across all tracked prompts.

Airefs shows competitor mentions with more granularity. You see which specific content sources (Reddit threads, YouTube videos, etc.) competitors are using to shape AI answers. This is more actionable -- you can reverse-engineer their strategy and replicate it.

Both tools send alerts when competitors get mentioned and you don't. Both let you track multiple competitors simultaneously.

Verdict: Airefs gives you more actionable competitor intelligence. Otterly.AI gives you broader coverage.

Prompt research and keyword discovery

Otterly.AI includes AI keyword research to "discover the search prompts your audience is asking on ChatGPT, Perplexity, and Google." This is useful for identifying new prompts to track and content gaps to fill.

Airefs has limited prompt research capabilities. The focus is more on tracking the prompts you already know matter, not discovering new ones.

Verdict: Otterly.AI has the edge on prompt discovery.

What both tools are missing

Neither Otterly.AI nor Airefs helps you create content or fix the gaps they identify. They're monitoring dashboards. They show you the problem -- "you're not visible for this prompt" or "this competitor is beating you" -- but they don't help you solve it.

You're left to manually create content, optimize pages, or engage on Reddit/YouTube yourself. There's no AI writing agent, no content gap analysis, no automated optimization.

This is where the monitoring-only model breaks down. You end up with a dashboard full of red flags but no clear path to green.

If you want the full loop -- find gaps, generate content, track results -- you need a platform like Promptwatch that combines monitoring with content generation and optimization tools.

Pros and cons

Otterly.AI pros

• Covers 6 AI platforms (broadest coverage in this comparison)
• GEO Audit tool diagnoses on-page issues
• Prompt research helps discover new tracking opportunities
• 14-day free trial (longer than Airefs)
• Established player with proven track record

Otterly.AI cons

• No Reddit, YouTube, or LinkedIn tracking
• Expensive ($189/mo for 100 prompts)
• Website-citation focus misses the content sources that actually shape AI answers
• Monitoring-only -- no content creation or optimization help

Airefs pros

• 17% cheaper at entry level ($24 vs $29/mo)
• Unlimited prompts at $49/mo (vs $189/mo for 100 at Otterly.AI)
• Tracks Reddit, YouTube, LinkedIn, G2, Quora -- the content that shapes AI answers
• Shows specific posts/threads that influenced answers (highly actionable)
• Faster setup ("up and running in two minutes")

Airefs cons

• Only covers ChatGPT and Perplexity (no Gemini, Copilot, Google AI products)
• No GEO Audit or diagnostic tools
• Limited prompt research capabilities
• Shorter free trial (7 days vs 14)
• Monitoring-only -- no content generation

Who should pick which tool

Pick Otterly.AI if:

• You need to track brand mentions across all major AI platforms (ChatGPT, Perplexity, Gemini, Copilot, Google AI)
• You want a GEO Audit tool to diagnose on-page issues
• You're focused on website citations rather than social/community content
• You have budget for $189/mo+ and need more than 100 prompts
• You value prompt research and keyword discovery

Pick Airefs if:

• You're primarily concerned with ChatGPT and Perplexity (the two biggest AI search engines)
• You want to see the actual Reddit threads, YouTube videos, and LinkedIn posts shaping AI answers
• You're on a tighter budget ($24-$49/mo vs $29-$189/mo)
• You need unlimited prompts without paying $189/mo
• You want more actionable competitor intelligence (see exactly what content they're using)

Pick neither if:

• You need more than monitoring -- you want content gap analysis, AI writing, and optimization tools. In that case, look at Promptwatch, which combines monitoring with content generation and a full action loop.

Final verdict

Airefs wins on value. $49/mo for unlimited prompts beats $189/mo for 100 prompts. The Reddit/YouTube/LinkedIn tracking is a major differentiator -- those content sources matter more than most website citations when it comes to shaping AI answers. The ability to see specific threads and posts gives you a clear action plan.

Otterly.AI wins on breadth and diagnostics. If you need to track Gemini, Copilot, and Google AI products, Otterly.AI is the only option here. The GEO Audit tool adds diagnostic value that Airefs lacks.

But both tools are monitoring-only. They tell you what's wrong but don't help you fix it. You're left to create content, optimize pages, and engage on social platforms yourself. For most teams, that's the real bottleneck -- not knowing where you're invisible, but having the time and resources to actually do something about it.
