Overview
Ceyo
Ceyo is a GEO (Generative Engine Optimization) platform that tracks how your brand shows up across ChatGPT, Gemini, Claude, and Perplexity. The core pitch: comprehensive prompt analytics with visibility scores, sentiment tracking, and competitor mentions across thousands of queries. The interface leans heavily on data tables -- you get prompt-by-prompt breakdowns showing visibility percentage, sentiment (positive/neutral/negative), average position, impact level, and which brands appear alongside yours. Ceyo is newer to the market but positions itself as a data-rich alternative for teams that want granular metrics.
Pricing starts at $49/mo for the Core plan, with Standard and Enterprise tiers available. No free trial mentioned on the site. Target audience: marketing teams and agencies that need detailed AI search analytics and are willing to pay for depth.
OtterlyAI
Otterly.AI is the more established AI search monitoring platform, used by 20,000+ marketers according to their site. It tracks brand mentions and website citations across ChatGPT, Google AI Overviews, Perplexity, Gemini, Copilot, and AI Mode. The differentiator here is the GEO audit tool -- it analyzes 25+ on-page factors to show you what's blocking your site from getting cited, then gives you a roadmap to fix it. OtterlyAI also includes AI keyword research to discover the prompts your audience is actually asking.
Pricing is more accessible: free trial available, then $29/mo for Lite (15 prompts), $189/mo for Standard (100 prompts), and a Premium tier. The freemium model makes it easier to test before committing. Target audience: marketers and SEO teams looking for an affordable entry point into AI search visibility, with room to scale.

Head-to-head feature deep-dive
Platform coverage
Ceyo tracks ChatGPT, Gemini, Claude, and Perplexity. OtterlyAI covers ChatGPT, Perplexity, Gemini, Google AI Overviews, Google AI Mode, and Microsoft Copilot -- notably missing Claude but adding three Google/Microsoft variants that Ceyo doesn't explicitly list.
The practical difference: if you care about Claude (Anthropic's model), Ceyo has you covered. If you care about Google AI Overviews (the snippets that appear in traditional Google search) or Copilot (Microsoft's AI assistant), OtterlyAI is the only option here. For most brands, Google AI Overviews matter more than Claude because they appear in high-intent search results, so OtterlyAI's coverage is more strategically useful.
Verdict: OtterlyAI wins on breadth. Google AI Overviews alone is a major differentiator.
Prompt analytics and tracking
Ceyo's strength is granular prompt-level data. The demo table on their site shows:
- Visibility percentage (how often your brand appears for a given prompt)
- Sentiment (positive/neutral/negative)
- Average position
- Impact level (high/medium/low relevance or volume)
- Competing brands mentioned
- Category and geography tags
This is useful if you want to slice data by sentiment or see exactly which prompts are driving positive vs. negative mentions. The table format makes it easy to export and analyze.
OtterlyAI focuses more on Share of Voice and citation tracking -- which brands get recommended, which websites get cited, and how you compare to competitors. The emphasis is less on sentiment and more on presence: are you showing up at all, and if so, how often relative to competitors?
Verdict: Ceyo gives you richer per-prompt metadata (sentiment, impact scoring). OtterlyAI gives you competitive context (Share of Voice). Pick based on whether you care more about sentiment nuance or market share.
GEO audit and optimization guidance
OtterlyAI's GEO audit tool is the standout feature here. It scans your site for 25+ on-page factors that influence AI citations -- things like E-E-A-T signals, entity optimization, structured data, content depth, and topical authority. You get a diagnostic report showing strengths and weaknesses, plus recommendations on what to fix.
Ceyo doesn't mention a comparable audit tool. The platform shows you the visibility data but doesn't explicitly guide you on how to improve it. You're left to interpret the metrics and figure out next steps yourself.
This is a big gap. One Reddit user reviewing similar tools noted: "Strong on diagnostics but all diagnostics, no creation. It tells you what to fix, but doesn't help you fix it." OtterlyAI at least tells you what to fix. Ceyo doesn't even do that -- it's pure monitoring.
Verdict: OtterlyAI wins decisively. The GEO audit is the difference between a dashboard and an optimization tool.
Worth noting: if you're looking for a platform that goes beyond diagnostics to actually help you create optimized content, Promptwatch fills that gap with AI-generated articles grounded in citation data and competitor analysis.

AI keyword research
OtterlyAI includes AI keyword research to discover the prompts your audience is asking on ChatGPT, Perplexity, and Google. This is essentially prompt discovery -- surfacing conversational queries you should be targeting but might not know about.
Ceyo doesn't mention a keyword research feature. You're presumably tracking prompts you manually input, not discovering new ones.
Verdict: OtterlyAI wins. Keyword research is table stakes for any search optimization tool, AI or otherwise.
Competitor benchmarking
Both platforms track competitor mentions. Ceyo shows you which brands appear alongside yours in AI responses, with visibility scores for each. OtterlyAI emphasizes Share of Voice -- your percentage of mentions relative to competitors across tracked prompts.
The difference is presentation. Ceyo gives you a list of competing brands per prompt. OtterlyAI gives you an aggregate market share view. Both are useful; the latter is better for executive reporting ("we have 12% Share of Voice vs. 18% for Competitor X").
Verdict: Tie. Different angles on the same data.
User interface and ease of use
Ceyo's interface, based on the demo screenshots, is table-heavy. Lots of columns, sortable data, filters by category/geography/sentiment. It feels like a BI tool -- powerful if you know what you're looking for, potentially overwhelming if you're new to AI search monitoring.
OtterlyAI's site emphasizes dashboards and visual reporting. The messaging is more beginner-friendly ("see where you show up, what's being said"), and the GEO audit tool provides a clear starting point for new users.
Verdict: OtterlyAI is more approachable for first-time users. Ceyo is better for analysts who live in spreadsheets.
Pricing and value
| Plan | Ceyo | OtterlyAI |
|---|---|---|
| Free trial | Not offered | Yes |
| Entry tier | $49/mo (Core) | $29/mo (Lite, 15 prompts) |
| Mid tier | Standard (price not listed) | $189/mo (Standard, 100 prompts) |
| High tier | Enterprise (custom) | Premium (price not listed) |
| Annual discount | Available | Not specified |
OtterlyAI is 40% cheaper at the entry level ($29 vs. $49) and includes a free trial. The Lite plan's 15-prompt limit is tight, but it's enough to test the platform and see if AI search monitoring matters for your brand. Ceyo's $49 Core plan doesn't specify a prompt limit, which could mean unlimited or could mean "contact sales" -- the lack of transparency is a red flag.
At the mid tier, OtterlyAI's $189/mo for 100 prompts is a known quantity. Ceyo's Standard pricing isn't public, so you can't comparison-shop without talking to sales.
Verdict: OtterlyAI wins on transparency and affordability. Ceyo might offer better value at higher tiers, but you can't tell from the website.

Who should pick which tool
Pick Ceyo if:
- You need sentiment tracking and want to monitor positive vs. negative brand mentions in AI responses
- Claude (Anthropic) is a priority platform for your audience
- Your team is comfortable with data tables and doesn't need hand-holding
- You're willing to pay $49/mo+ without a trial to access more granular prompt analytics
- You already know which prompts to track and don't need discovery tools
Pick OtterlyAI if:
- You're new to AI search monitoring and want a free trial before committing
- Google AI Overviews and Copilot matter for your SEO strategy
- You need a GEO audit to understand why you're not getting cited and what to fix
- You want AI keyword research to discover new prompts your audience is asking
- Budget is tight and $29/mo is more palatable than $49/mo
- You want a platform with proven adoption (20,000+ users) and market validation
Pick neither if:
- You need a platform that not only monitors but also helps you create optimized content -- in that case, look at tools like Promptwatch that combine tracking with AI content generation and gap analysis
Final verdict
OtterlyAI is the better choice for most teams in 2026. The free trial removes risk, the $29 entry price is accessible, and the GEO audit tool gives you a clear path from data to action. Google AI Overviews coverage is critical because those snippets appear in traditional search results where intent is highest. The 20,000+ user base signals market fit.
Ceyo has merit if you specifically need sentiment analysis or Claude tracking, but the lack of a free trial, higher starting price, and missing optimization features make it a harder sell. The interface is data-rich, but data without guidance is just noise. You're paying $49/mo for a monitoring dashboard when OtterlyAI gives you monitoring plus audits plus keyword research for $29/mo.
The gap widens at scale. OtterlyAI's $189/mo Standard plan (100 prompts) is transparent and predictable. Ceyo's Standard pricing is hidden, which suggests it's either comparable (so why hide it?) or more expensive (which would make it even less competitive).
One-liner: OtterlyAI wins on price, features, and actionability -- Ceyo is a data-rich alternative for teams that prioritize sentiment tracking over optimization guidance.
