Overview

Otterly.AI

Otterly.AI positions itself as "the #1 rated AI search monitoring platform" with automatic tracking across six major AI search engines. The platform targets brands that want comprehensive coverage of where their name shows up when users ask ChatGPT, Perplexity, or Google AI for recommendations. Otterly.AI's pitch centers on moving beyond traditional SEO -- "stop Googling, start monitoring" -- and includes a GEO audit tool to help you fix on-page issues holding back your AI visibility.

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

PromptScout

PromptScout takes a more focused approach, monitoring three core AI platforms (ChatGPT, Gemini, Google AI Overviews) with an emphasis on actionable insights and competitor benchmarking. The dashboard shows you not just whether you're mentioned, but which competitors AI recommends instead, which domains get cited most often, and what AI systems actually say about your brand in their own words.

PromptScout offers a freemium model with a genuinely usable free tier, then paid plans from $15/mo (Starter: 50 prompts), $39/mo (Growth: 150 prompts), $99/mo (Pro: 500 prompts), plus custom agency pricing. Early adopters get 30% off for three months with code FOUNDER30.

Side-by-Side Comparison

Pricing: PromptScout wins on value for small teams

The pricing gap is stark. PromptScout's Starter plan costs half what Otterly.AI charges and includes more than 3x the prompts. For a solo founder or small marketing team testing AI visibility for the first time, PromptScout's free tier removes all friction -- you can start monitoring today without a credit card.

Otterly.AI's pricing makes more sense for established brands with budget allocated to AI search optimization. The 14-day trial helps, but you're committing to $29/mo minimum after that. The jump to $189/mo for 100 prompts feels steep compared to PromptScout's $39/mo for 150 prompts.

One caveat: Otterly.AI's Premium plan offers unlimited prompts, which could matter for agencies or enterprises monitoring dozens of brands. PromptScout caps out at 500 prompts on the Pro plan before moving to custom agency pricing.

AI engine coverage: Breadth vs depth

Otterly.AI monitors six AI platforms: ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, Gemini, and Microsoft Copilot. That's comprehensive coverage of the major players in AI search. If your audience uses Perplexity heavily or you want to track Copilot specifically, Otterly.AI has you covered.

PromptScout focuses on three engines: ChatGPT, Gemini, and Google AI Overviews. These are arguably the three that matter most for brand visibility -- ChatGPT dominates conversational AI, Gemini powers Google's AI features, and AI Overviews appear in traditional search results. PromptScout's bet is that monitoring these three well beats monitoring six platforms with less depth.

In practice, the difference matters depending on your audience. If you're a B2B SaaS tool and your buyers use Perplexity for research, Otterly.AI's coverage is valuable. If you're optimizing for mainstream consumer queries, ChatGPT and Google AI Overviews are the battlegrounds that matter -- PromptScout covers those.

Worth noting: if you're also looking to track how your brand shows up across a wider range of AI models (including Claude, DeepSeek, Grok, Meta AI, and Mistral), Promptwatch monitors 10+ engines and adds content gap analysis to help you fix visibility issues, not just track them.

Features: Monitoring vs optimization

Brand monitoring and citation tracking

Both platforms automatically track when AI engines mention your brand and which websites they cite. Otterly.AI shows you "which brands get recommended, which websites get cited, and where you stand." PromptScout breaks this down further with a source domain analysis showing exactly which sites (G2, TechCrunch, Reddit, etc.) drive your citations, categorized by type (editorial, UGC, review sites).

PromptScout's citation breakdown is more actionable. Seeing that Reddit drives 12 citations while your own blog drives 2 tells you where to focus -- build community presence, not just publish more blog posts.

Competitor analysis

Otterly.AI tracks competitor mentions and share of voice. PromptScout goes a step further with a competitor leaderboard showing exactly how many times each competitor gets mentioned versus your brand. The dashboard example shows "TechFlow: 47 mentions, Flowwise: 38, StreamAI: 32" -- concrete numbers that make the competitive gap obvious.

Both platforms let you see what AI says about competitors, but PromptScout surfaces this as "AI Insights" with specific recommendations ("Flowwise is your closest competitor in AI responses -- focus on content creation").

GEO auditing: Otterly.AI's differentiator

Otterly.AI includes a GEO audit tool that analyzes 25+ on-page factors to identify what's holding your site back from earning citations. This is a real differentiator -- most AI visibility tools (including PromptScout) stop at monitoring. Otterly.AI at least attempts to help you fix the problem.

The audit covers technical factors, content structure, and optimization opportunities. It's not as comprehensive as a full content gap analysis (which would show you specific prompts competitors rank for that you don't), but it's more than just a dashboard of metrics.

PromptScout doesn't include any audit or optimization features. You see the data, you figure out what to do about it.

AI keyword research

Otterly.AI converts traditional keywords into conversational prompts users ask AI engines. This helps you understand how people phrase questions to ChatGPT versus how they type queries into Google. Useful for content planning.

PromptScout's keyword research is more limited -- the focus is on tracking specific prompts you define, not discovering new ones.

Visibility scoring

Otterly.AI uses "Share of Voice" metrics to show your brand's presence relative to competitors. PromptScout calculates an "AI Visibility Score" as a percentage (e.g. "78% -- mentioned in 31 of 40 responses"). Both approaches work; PromptScout's percentage feels more intuitive at a glance.

User experience and interface

PromptScout's dashboard (based on the live website data) looks cleaner and more modern. The overview shows your visibility score, which AI engines mentioned you, competitor rankings, top citation sources, and AI-generated insights all on one screen. It's designed for quick daily check-ins.

Otterly.AI's interface isn't shown in the website data, but the marketing copy emphasizes "automatically track brand mentions" and "stay ahead of competitors by spotting opportunities." The focus seems to be on comprehensive data collection across multiple engines rather than streamlined presentation.

For teams that just want to check "are we visible or not?" once a week, PromptScout's simpler approach probably wins. For teams doing deep competitive analysis across six platforms, Otterly.AI's breadth matters more than UI polish.

Automated monitoring and alerts

Both platforms run automated checks and send alerts when your visibility changes. Neither provides specific details on alert customization or frequency in the available data, so assume basic functionality is similar.

What's missing from both

Neither platform offers:

• AI crawler log analysis: You can't see when ChatGPT or Perplexity's crawlers visit your site or what errors they encounter
• Content generation: No built-in tools to create content optimized for AI citations
• Traffic attribution: No way to connect AI visibility to actual website traffic or conversions
• Reddit/YouTube-specific tracking: PromptScout shows Reddit as a citation source, but neither platform monitors Reddit discussions or YouTube videos that influence AI recommendations
• Multi-language monitoring: No mention of tracking AI responses in languages other than English

• You have budget for $29-189/mo and need more than 50 prompts

Otterly.AI makes sense for established brands with dedicated marketing teams and budget allocated to AI search optimization. The GEO audit feature adds value if you're willing to act on the recommendations.

Who should pick PromptScout

Choose PromptScout if:

• You're just starting to explore AI visibility tracking
• You want to test for free before committing any budget
• ChatGPT, Gemini, and Google AI Overviews are your priority engines
• You need more prompts per dollar (50 for $15 vs 15 for $29)
• You value a clean dashboard and actionable insights over feature breadth
• You're a solo founder, small team, or agency managing multiple clients on a tight budget
• You want to see exactly which domains drive your citations and what AI says about you

PromptScout is the better entry point for teams new to AI visibility monitoring. The free tier removes all risk, and the paid plans offer better value at the low end.

Final verdict

PromptScout wins on value and accessibility. The free tier, lower entry price, and better prompt-to-dollar ratio make it the obvious choice for small teams and anyone testing AI visibility tracking for the first time. The cleaner interface and citation source breakdown also make the data more actionable.

Otterly.AI wins on breadth and optimization features. If you need to monitor six AI engines instead of three, or you want built-in audit tools to identify what's holding you back, Otterly.AI justifies the higher price. The GEO audit is a real differentiator that moves beyond pure monitoring.

For most teams starting out: try PromptScout's free tier, see if AI visibility matters for your brand, then upgrade to paid if you need more prompts. If you outgrow PromptScout's three-engine focus or want optimization tools, Otterly.AI is the natural next step.

One-liner: PromptScout is the better value for testing and small-scale monitoring; Otterly.AI is the better investment for comprehensive coverage and optimization once you're committed to AI search visibility.
