Key Takeaways
- Gauge is 6x cheaper for small teams: Starter plan at $99/mo (100 prompts, ChatGPT only) vs Authoritas P1 at £90/mo (~$113) for 2,000 credits -- but Authoritas credits cover more LLMs per query
- Authoritas covers more AI models out of the box: 7 LLMs (ChatGPT, Perplexity, Claude, Gemini, DeepSeek, Copilot, Google AI Overviews) on all plans vs Gauge's ChatGPT-only on Starter, all models on Growth
- Gauge includes content generation: Built-in AI writing agent creates articles grounded in citation data. Authoritas is monitoring-only -- no content creation tools.
- Credit-based vs prompt-based pricing: Authoritas uses credits (1 query = 1-3 credits depending on LLM), Gauge uses monthly prompt limits. Different mental models for budgeting.
- Authoritas integrates with a full SEO platform: AI Tracker is part of a broader SEO suite (rank tracking, technical audits, backlinks). Gauge is AI visibility-focused.
- Gauge targets mid-market brands and agencies: Clear pricing tiers, self-serve signup. Authoritas skews enterprise with demo-required access and higher credit volumes.
Overview
Gauge
Gauge positions itself as a "strategic competitive intelligence" platform for AI visibility. It tracks brand mentions across ChatGPT, Claude, Gemini, Perplexity, Copilot, Google AI Mode, and AI Overviews, then gives you a roadmap to improve. The pitch: don't just monitor -- act. Gauge includes content gap analysis and an AI writing agent that generates articles designed to get cited by LLMs. Pricing starts at $99/mo for 100 prompts (ChatGPT only), jumping to $599/mo for 600 prompts across all models. Founded by a team that previously built SEO tools, Gauge launched in 2024 and targets mid-market brands, agencies, and e-commerce companies.
Authoritas AI Tracker
Authoritas AI Tracker is the AI visibility module inside Authoritas's broader SEO platform. It monitors brand mentions, sentiment, and citations across 7 LLMs: ChatGPT, Perplexity, Claude, Gemini, DeepSeek, Google AI Overviews, and Bing AI. You track how AI engines recommend your brand, which prompts drive visibility, and what sources LLMs cite. Pricing is credit-based: free tier with 50 credits, then £90/mo for 2,000 credits up to £1,125/mo for 42,000 credits. Each query costs 1-3 credits depending on the LLM. Authoritas is a UK-based company that's been in SEO software since 2011 -- the AI Tracker is their 2024 answer to generative search.

Pricing breakdown
Gauge pricing
| Plan | Price | Prompts/mo | LLMs | Articles/mo | Best for |
|---|---|---|---|---|---|
| Starter | $99/mo | 100 | ChatGPT only | 3 | Small brands testing AI visibility |
| Growth | $599/mo | 600 | All 7 models | 18 | Growing brands, agencies |
| Enterprise | Custom | Custom | All models | Custom | Large brands, multi-site tracking |
Gauge's pricing is straightforward: you pay for a fixed number of prompts per month. The catch is Starter only covers ChatGPT -- you need Growth ($599/mo) to monitor all LLMs. The included article generation is a differentiator: 3 articles on Starter, 18 on Growth.
Authoritas AI Tracker pricing
| Plan | Price | Credits/mo | Cost per credit | Best for |
|---|---|---|---|---|
| Free | £0 | 50 | £0 | Testing, small-scale monitoring |
| P1 | £90/mo (~$113) | 2,000 | £0.045 | Brands monitoring 1-2 categories |
| P2 | £225/mo (~$283) | 6,000 | £0.0375 | Mid-size brands, multiple product lines |
| P3 | £495/mo (~$623) | 15,000 | £0.033 | Large brands, extensive prompt sets |
| Enterprise | £1,125/mo (~$1,416) | 42,000 | £0.027 | Publishers, enterprise-scale tracking |
Authoritas uses credits. Each query costs 1-3 credits depending on the LLM (GPT-4o mini is cheaper, Claude 3.5 Sonnet costs more). This means your effective "prompts per month" varies based on which models you query. A 2,000-credit plan might give you 2,000 ChatGPT queries or ~700 Claude queries. The free tier (50 credits) is a nice testing ground.
Price comparison example: If you want to monitor 100 prompts across all LLMs monthly, Gauge charges $99/mo but limits you to ChatGPT. Authoritas P1 at £90/mo gives you 2,000 credits -- enough for 100 prompts across multiple models if you average 2-3 credits per query. For 600 prompts across all models, Gauge is $599/mo. Authoritas would need ~1,800 credits (assuming 3 credits/query) -- so P2 at £225/mo is significantly cheaper. But Gauge includes content generation; Authoritas doesn't.
Feature deep-dive
LLM coverage and tracking
Gauge monitors 7 AI models: ChatGPT, Claude, Gemini, Perplexity, Copilot, Google AI Mode, and Google AI Overviews. On the Starter plan, you only get ChatGPT. Growth and Enterprise unlock all models. Gauge tracks brand mentions, citation sources, and share of voice. You see which prompts trigger mentions and how you stack up against competitors.
Authoritas also covers 7 LLMs: ChatGPT, Perplexity, Claude, Gemini, DeepSeek, Copilot, and Google AI Overviews. All models are available on every plan -- even the free tier. Authoritas adds sentiment analysis (positive/negative/neutral mentions) and tracks which sources LLMs cite. The credit system means you can mix and match models based on priority.
Verdict: Authoritas wins on flexibility -- all models on all plans, plus DeepSeek (which Gauge doesn't cover). Gauge's Starter plan being ChatGPT-only is a limitation. If you need multi-LLM tracking from day one, Authoritas is the better pick.
Content gap analysis and recommendations
Gauge's core pitch is the action loop: track visibility, identify gaps, create content. The platform shows you which prompts competitors rank for but you don't. It highlights missing topics and angles. Then the built-in AI writing agent generates articles designed to fill those gaps. You get 3 articles/mo on Starter, 18 on Growth. The content is grounded in citation data -- not generic SEO filler.
Authoritas doesn't include content generation. It's a monitoring and analysis tool. You see the data (mentions, citations, sources), but you're on your own for creating content. The platform does show which sources LLMs cite, so you can reverse-engineer what works, but there's no automated writing or gap-filling.
Verdict: Gauge is the clear winner if you want an end-to-end workflow. Authoritas is monitoring-only. If you have a content team and just need data, Authoritas is fine. If you want the platform to help you create content, Gauge is the only option here.
Competitor analysis
Both platforms offer share of voice tracking. Gauge shows competitor heatmaps -- which brands are winning for each prompt, across which LLMs. You can see where you're invisible and where competitors dominate. The interface emphasizes visual comparisons.
Authoritas tracks SOV trends over time and lets you compare your brand against competitors. The publisher-focused features (tracking how your content is cited, which articles drive mentions) are stronger here. Authoritas also breaks down sentiment by competitor, so you can see if a rival is getting positive or negative mentions.
Verdict: Tie. Both do competitive benchmarking well. Gauge's heatmaps are more visual; Authoritas's sentiment breakdown is more granular. Pick based on whether you care more about quick visual scans (Gauge) or detailed sentiment analysis (Authoritas).
Integration with broader SEO workflows
Gauge is a standalone AI visibility tool. It doesn't integrate with rank tracking, backlink analysis, or technical SEO audits. You'd pair it with another SEO platform (Ahrefs, Semrush, etc.) if you need those capabilities.
Authoritas AI Tracker is part of a full SEO suite. The base SEO platform (separate pricing: Essential £99/mo, Advanced £399/mo, Expert $799/mo) includes rank tracking, technical audits, backlink monitoring, and keyword research. You can view AI visibility and organic rankings side by side. If you're already an Authoritas customer, adding AI Tracker is seamless. If you're not, you're paying for two separate products.
Verdict: Authoritas wins if you want one platform for everything. Gauge wins if you already have an SEO stack and just need AI visibility bolted on.
Ease of use and onboarding
Gauge has self-serve signup. You can start a free trial, connect your brand, and begin tracking immediately. The interface is modern and visual -- lots of charts, heatmaps, and dashboards. The learning curve is low.
Authoritas requires a demo for paid plans. The free tier (50 credits) is self-serve, but to unlock real volume, you talk to sales. The platform is more complex -- it's built for enterprise users who want deep data. The UI feels like a traditional SEO tool (tables, filters, exports) rather than a sleek SaaS dashboard.
Verdict: Gauge is easier to get started with. Authoritas is more powerful but requires more setup and sales conversations.
Reporting and data export
Gauge provides dashboards and visualizations. Reporting features aren't detailed on the website, but the focus is on actionable insights rather than raw data dumps.
Authoritas is built for reporting. You can export data, create custom views, and generate reports for stakeholders. The enterprise tier (42,000 credits) is designed for agencies and publishers who need white-label reporting.
Verdict: Authoritas is better for agencies and teams that need to present data to clients or executives. Gauge is better for internal teams that want quick insights.
Who should pick Gauge
- Mid-market brands that want an all-in-one AI visibility solution without enterprise complexity
- Agencies managing AI visibility for multiple clients and need content generation included
- E-commerce companies that want to track product mentions in AI search and create optimized content quickly
- Teams that want self-serve access -- no demos, no sales calls, just sign up and start
- Brands that prioritize action over monitoring -- if you want the platform to help you create content, not just show you data
Gauge makes sense if you're a growing brand or agency that needs AI visibility tracking plus content creation in one package. The $599/mo Growth plan is competitive for what you get (600 prompts, all LLMs, 18 articles). The Starter plan is a cheap entry point if you only care about ChatGPT.
Who should pick Authoritas AI Tracker
- Enterprise brands that need high-volume tracking (15,000+ credits/mo) and already have content teams
- Publishers tracking how their articles are cited by LLMs and exploring licensing opportunities
- Brands already using Authoritas for SEO -- adding AI Tracker is a natural extension
- Teams that want sentiment analysis -- Authoritas tracks positive/negative/neutral mentions, Gauge doesn't
- Companies that need a free tier to test before committing -- 50 credits is enough to validate the concept
Authoritas is the better pick if you're a large brand or publisher that needs monitoring at scale and already has a content operation. The credit-based pricing is more flexible for high-volume use cases. The integration with Authoritas's SEO platform is a bonus if you're consolidating tools.

Final verdict
Pick Gauge if you're a mid-market brand or agency that wants AI visibility tracking and content creation in one package. The $599/mo Growth plan is a solid deal for 600 prompts across all LLMs plus 18 articles. The self-serve model and modern interface make it easy to get started. Gauge is built for teams that want to act on the data, not just stare at dashboards.
Pick Authoritas AI Tracker if you're an enterprise brand or publisher that needs high-volume monitoring, sentiment analysis, and integration with a full SEO platform. The credit-based pricing scales better for large prompt sets, and the free tier is a low-risk way to test. Authoritas is monitoring-first -- you'll need your own content team to act on the insights.
If you're also looking to track how your brand shows up in AI search results with a focus on closing the loop from visibility to content optimization, Promptwatch offers a complementary approach. It combines AI visibility tracking with content gap analysis, an AI writing agent, and traffic attribution -- covering the full cycle from finding gaps to creating content to measuring results.
The choice comes down to whether you want a tool that helps you create (Gauge) or a tool that helps you monitor (Authoritas). Both do competitive tracking well. Both cover the major LLMs. The real difference is the action layer -- Gauge has it, Authoritas doesn't.
