Key takeaways
- Pendium.ai is a lightweight, freemium AI visibility scanner built for SMBs and SaaS companies that want a quick read on how ChatGPT, Claude, and Gemini perceive their brand -- no setup, no credit card, results in 2 minutes.
- Authoritas is a full-stack SEO + AI search platform with traditional rank tracking baked in alongside AI monitoring. It's built for eCommerce brands, publishers, and agencies that need both worlds in one place.
- Authoritas monitors more AI models (7 platforms including DeepSeek and Bing AI vs. Pendium's 3), and its pricing is transparent starting at £99/mo. Pendium's paid tiers aren't publicly listed, which makes budget planning harder.
- If you already have an SEO stack and just want AI visibility layered on top, Authoritas is the more natural fit. If you're starting from scratch and want something fast and low-commitment, Pendium.ai gets you in the door for free.
- Neither tool offers deep content generation or AI crawler log analysis. Teams that want to go beyond monitoring and actually fix their AI visibility gaps should look at platforms built around the full optimization loop.
- For agencies managing multiple clients across competitive niches, Authoritas has the infrastructure (custom enterprise pricing, multi-site tracking, eCommerce-specific features). Pendium.ai doesn't appear to have an agency tier.
Overview
Pendium.ai
Pendium.ai pitches itself as the tool that teaches AI agents to recommend your business. The core idea is simple: find out what ChatGPT, Claude, and Gemini are saying about you, then publish the content that gets you recommended to the right people. The free visibility scan is the main entry point -- you get results in about 2 minutes with no credit card required. It's clearly aimed at business owners and marketers who aren't deeply technical and want a fast, accessible answer to "does AI know who I am?"
The product feels early-stage but intentional. The focus on "customer personas" and matching AI recommendations to the right audience is a nice angle -- it's not just "are you mentioned?" but "are you mentioned to the right people?" That said, the lack of public pricing for paid plans and the relatively narrow set of monitored AI models (ChatGPT, Claude, Gemini) limits how far you can take it.
Authoritas AI Tracker
Authoritas has been around as an SEO platform for years, and the AI Tracker is their answer to the shift toward AI-driven search. The positioning is honest: "Rankings drop. AI ignores your content. Traditional SEO tools weren't built for the new world of AI-driven search -- so we built one that is." That's a fair summary of where the market is.
What sets Authoritas apart from pure-play AI visibility tools is the depth of the traditional SEO layer underneath. You get keyword rank tracking, site audits, backlink analysis, and content optimization alongside AI monitoring. For an eCommerce brand or publisher that needs both, that's genuinely useful. The AI monitoring side covers ChatGPT, Perplexity, Claude, Gemini, DeepSeek, Google AI Overviews, and Bing AI -- a broader spread than most competitors at this price point.

Head-to-head feature deep-dive
AI model coverage
Pendium.ai monitors three AI platforms: ChatGPT, Claude, and Gemini. That covers the three most consumer-facing models, which is a reasonable starting point for most SMBs. But it misses Perplexity (which is increasingly a go-to for research queries), DeepSeek (growing fast in certain markets), and Google AI Overviews (which is arguably the highest-traffic AI surface for most brands right now).
Authoritas covers seven platforms: ChatGPT, Perplexity, Claude, Gemini, DeepSeek, Google AI Overviews, and Bing AI. For brands in competitive niches where AI search is already driving meaningful traffic, that breadth matters. You're not flying blind on any major platform.
Verdict: Authoritas wins on coverage. If Perplexity or Google AI Overviews are relevant to your business (and for most brands they are), Pendium.ai's three-model focus is a real limitation.
Traditional SEO integration
This is where the two tools diverge most sharply. Pendium.ai is AI-visibility-only. There's no keyword rank tracking, no site audit, no backlink analysis. If you already have an SEO stack (Semrush, Ahrefs, Search Console), that's fine -- Pendium slots in as a focused add-on. But if you're looking to consolidate tools, it won't help.
Authoritas is a full SEO platform that added AI monitoring. That means you can track traditional keyword rankings alongside your AI visibility scores in the same dashboard. For eCommerce teams managing large product catalogs or publishers tracking content performance, that unified view is genuinely valuable -- you can see when a page loses traditional ranking and also drops out of AI citations, which tells a more complete story.
Verdict: Authoritas wins clearly for teams that need both. Pendium.ai is fine if you're already covered on traditional SEO.
Ease of entry and setup
Pendium.ai's free scan is genuinely frictionless. You enter your business, get results in 2 minutes, no account required. That's a strong hook for anyone who's curious but not ready to commit. The product is designed to be accessible to non-technical users -- the language around "no engineering skills required" is consistent throughout.
Authoritas requires a demo booking or direct signup. There's no free tier to poke around in. For a team evaluating tools, that's a higher barrier. The platform is more complex by design -- there's more to configure, more data to interpret, and a steeper learning curve if you're new to SEO tooling.
Verdict: Pendium.ai wins on accessibility. Authoritas is worth the setup time if you're serious about it, but you're committing before you've seen the product.
Competitor and market analysis
Authoritas has share-of-voice trend tracking, competitor comparison across AI platforms, and persona/journey mapping that shows how different customer types interact with AI recommendations. The mockups on their site show brand comparisons (Patagonia vs. Lululemon vs. Nike, for example) with percentage breakdowns by date -- that's the kind of competitive intelligence marketing teams actually use.
Pendium.ai's competitive analysis capabilities aren't clearly documented. The product appears to focus more on your own brand's visibility score and content recommendations rather than deep competitive benchmarking.
Verdict: Authoritas wins on competitive intelligence. If you're in a crowded category and want to know exactly where you stand relative to competitors in AI search, Authoritas has the tooling for it.
Content guidance and optimization
Pendium.ai's core promise is "publish the content that gets you recommended." The product positions content guidance as a key output -- you find out what AI says about you, then you get direction on what to publish to improve that. The specifics of how deep this goes aren't fully transparent from the public-facing product, but the intent is there.
Authoritas is primarily a monitoring and analysis platform. It surfaces data about where you're visible and where you're not, but it doesn't appear to have a built-in content generation or optimization workflow. You'd need to take the insights and act on them separately.
Neither tool offers the kind of full content generation loop -- gap analysis, AI-written articles grounded in citation data, then tracking the results -- that more specialized platforms provide. If that's what you're after, it's worth knowing that Promptwatch is built specifically around that cycle: find the gaps, generate content engineered for AI citation, track what improves.
Verdict: Pendium.ai has more explicit content guidance. Authoritas is stronger on the data side but leaves the "what do I do about it" question more open.
Pricing and value
| Plan | Pendium.ai | Authoritas |
|---|---|---|
| Free | Free visibility scan | No |
| Entry paid | Not publicly listed | £99/mo (Essential) |
| Mid-tier | Not publicly listed | ~£299-499/mo (estimated) |
| Top tier | Not publicly listed | £799/mo (Expert) |
| Enterprise | Not publicly listed | Custom |
Authoritas is transparent about pricing, which is a meaningful advantage when you're evaluating tools. You know what you're getting into. Pendium.ai's paid tiers are unlisted, which means you have to go through a sales conversation before you can make an informed decision. That's a friction point.
At £99/mo, Authoritas's entry plan is accessible for a small team. The £799/mo Expert tier is a serious investment, but it's aimed at agencies and larger brands where the ROI case is easier to make.
Verdict: Authoritas wins on pricing transparency. Pendium.ai's freemium entry is great, but the opacity around paid plans makes it hard to evaluate seriously.

Final verdict
These two tools are solving related problems for very different audiences. Pendium.ai is a fast, accessible entry point for smaller businesses that want to understand their AI visibility without a big commitment. Authoritas is a serious platform for teams that need both traditional SEO and AI monitoring in one place, with the depth and breadth to match.
If you're a startup or SMB just getting started with AI search, Pendium.ai's free scan is worth running today -- it costs nothing and takes 2 minutes. But if you're running an eCommerce brand or agency and need competitive intelligence, multi-model coverage, and a platform that scales, Authoritas is the more complete tool. The lack of transparent pricing from Pendium makes it hard to recommend as a long-term solution without knowing what you're actually paying for.
