- Pricing gap is massive: OtterlyAI starts at $29/mo for 15 prompts while Authoritas starts at £99/mo (~$125) -- over 4x more expensive at entry level

Overview
Authoritas AI Tracker
Authoritas is a UK-based SEO platform that added AI search monitoring to its existing suite of traditional SEO tools. It tracks brand mentions, sentiment, and citations across ChatGPT, Perplexity, Claude, Gemini, DeepSeek, Google AI Overviews, and Bing AI. The platform targets eCommerce brands, publishers, and agencies managing competitive niches with global reach. Pricing starts at £99/mo for the Essential plan and scales to £799/mo for Expert tier, with custom enterprise options available.

OtterlyAI
OtterlyAI is a dedicated AI search monitoring platform used by 20,000+ marketers. It tracks brand mentions and website citations across ChatGPT, Google AI Overviews, Perplexity, Gemini, Copilot, and AI Mode. The platform offers visibility dashboards, competitive benchmarking, and GEO (Generative Engine Optimization) audits. Pricing starts with a free tier, then $29/mo for Lite (15 prompts), $189/mo for Standard (100 prompts), and a Premium tier.
The pitch: pure AI search monitoring without the bloat. You're not paying for SEO features you might not need. Just track where your brand shows up in AI answers and optimize from there.
Side-by-Side Comparison
| Feature | Authoritas AI Tracker | OtterlyAI |
|---|---|---|
| Starting price | £99/mo (~$125) | $29/mo |
| Free tier | No | Yes |
| AI engines tracked | ChatGPT, Perplexity, Claude, Gemini, DeepSeek, Google AIO, Bing AI | ChatGPT, Perplexity, Gemini, Copilot, Google AIO, AI Mode |
| Traditional SEO tools | Yes (rank tracking, technical audits, backlinks) | No |
| GEO audit | Not mentioned | Yes (25+ on-page factors) |
| Competitive benchmarking | Yes (Share of Voice) | Yes |
| Keyword/prompt research | Journey mapping, persona-based | AI keyword research |
| Citation tracking | Yes | Yes |
| Target audience | Enterprise eCommerce, agencies, publishers | Marketers, SMBs, agencies |
| User base | Not disclosed | 20,000+ |

Pricing breakdown
| Plan | Authoritas AI Tracker | OtterlyAI |
|---|---|---|
| Free | Not available | Free tier (limited prompts) |
| Entry tier | Essential: £99/mo (~$125) | Lite: $29/mo (15 prompts) |
| Mid tier | Not specified between Essential and Expert | Standard: $189/mo (100 prompts) |
| High tier | Expert: £799/mo (~$1,010) | Premium (price not disclosed) |
| Enterprise | Custom pricing | Likely available |
The price gap is stark. OtterlyAI's entry point is accessible for solo marketers and small teams testing AI search optimization. Authoritas prices like an enterprise SEO platform because that's what it is -- AI tracking is one module among many.
If you only need AI search monitoring, paying £99/mo for Authoritas means you're subsidizing rank tracking and technical SEO features you might not touch. If you need both, the bundled pricing could make sense compared to buying separate tools.
Feature deep-dive
AI engine coverage
Both platforms cover the major players: ChatGPT, Perplexity, Google AI Overviews, and Gemini. Authoritas adds Claude, DeepSeek, and Bing AI. OtterlyAI includes Copilot and Google AI Mode.
The differences are minor. DeepSeek is a nice-to-have for brands targeting Chinese markets or tech-forward audiences. Claude matters if you're in B2B SaaS where developers use it heavily. AI Mode is Google's conversational search interface -- relevant if you're optimizing for mobile search behavior.
Verdict: Tie. Both cover what matters. The specific engine list won't make or break your decision.
Traditional SEO capabilities
This is where the platforms diverge completely.
Authoritas includes:
- Rank tracking for traditional search
- Technical SEO audits (crawl errors, site speed, indexation)
- Backlink analysis
- Content optimization recommendations
- Competitor analysis for organic search
OtterlyAI includes:
- None of the above
If you're running SEO for an eCommerce site or managing multiple clients, having AI visibility and traditional SEO in one dashboard saves tool sprawl. You can see how AI search performance correlates with organic rankings.
If you already use Ahrefs, Semrush, or another SEO platform and just need AI search monitoring, paying for duplicate SEO features makes no sense.
Verdict: Authoritas wins for teams that want consolidation. OtterlyAI wins for teams that want focus.
GEO auditing and optimization
OtterlyAI explicitly markets a "GEO Audit tool" that analyzes 25+ on-page factors to reveal what's blocking your site from earning AI citations. You get a checklist of strengths and weaknesses.
Authoritas doesn't highlight a dedicated GEO audit feature on their site. They emphasize journey mapping, persona-based prompt tracking, and Share of Voice trending -- more about monitoring than prescriptive optimization.
This is a meaningful gap. If you're new to AI search optimization and need guidance on what to fix, OtterlyAI's audit gives you a starting point. Authoritas assumes you know what to do with the data.
Verdict: OtterlyAI wins for actionable optimization guidance.
Prompt and keyword research
Authoritas uses journey mapping and persona-based tracking. You define customer journeys (e.g. "safety-conscious SUV buyer") and track how AI engines answer questions along that journey. The interface shows question types: informational, where to buy, branded, location-based.
OtterlyAI offers "AI Keyword Research" to discover search prompts your audience is asking on ChatGPT, Perplexity, and Google. The focus is on conversational keywords to guide content creation.
Both approaches work, just different philosophies. Authoritas is more structured around buyer journeys and personas -- good for eCommerce with defined customer segments. OtterlyAI is more exploratory -- good for content marketers hunting for topic gaps.
Verdict: Tie. Pick based on your workflow preference.
Competitive benchmarking
Both platforms track Share of Voice and show which competitors get mentioned in AI responses. Authoritas shows SOV trends over time with line graphs. OtterlyAI emphasizes seeing "which brands get recommended" and "where you stand."
No major difference here. Both give you the competitive context you need.
Verdict: Tie.
Reporting and integrations
Authoritas mentions Looker Studio integration explicitly -- you can pipe data into custom dashboards for client reporting. This matters for agencies managing multiple brands.
OtterlyAI doesn't mention Looker Studio or API access on their site. The platform seems more self-contained.
If you're an agency billing clients and need white-label reporting, Authoritas has the edge.
Verdict: Authoritas wins for agency reporting needs.
User base and adoption
OtterlyAI claims 20,000+ users and positions itself as "#1 rated AI search monitoring platform." The free tier and low entry price explain the volume.
Authoritas doesn't disclose user numbers. The £99/mo starting price and enterprise focus suggest a smaller, higher-value customer base.
Neither claim tells you which tool is better, but OtterlyAI's traction suggests product-market fit for the SMB and mid-market segment.
Verdict: OtterlyAI wins for proven adoption at scale.

Final verdict
This isn't a close call -- the right choice depends entirely on what you already have.
If you're running SEO for an eCommerce site and don't have a traditional SEO platform yet, Authoritas makes sense. You get rank tracking, technical audits, backlinks, and AI search monitoring in one subscription. The £99/mo entry price is reasonable compared to buying Ahrefs + a separate AI monitoring tool.
If you already use Semrush, Ahrefs, or another SEO suite and just need AI search visibility tracking, OtterlyAI is the obvious pick. You're not paying for duplicate features, the entry price is 4x cheaper, and the GEO audit gives you actionable next steps.
For most marketers reading this, OtterlyAI is the better fit. The $29/mo Lite plan gets you started, the free tier lets you test before committing, and the 20,000+ user base means there's a community figuring this stuff out alongside you. Authoritas is a solid enterprise choice, but you're paying a premium for bundled features you might not need.
