The honest one-paragraph version
Evertune is the best-known pure-play LLM monitoring tool. It tracks how brands are cited (or not) across ChatGPT, Perplexity, Google AI Overviews, and Claude — a real and growing measurement need that 90% of brands aren't yet doing.
Theia's AI Overview citation tracking covers the same surfaces, but it's one slice of one pillar (Visibility) in a four-pillar platform that also covers Demand, Sales, and Perception across Google, Amazon, retailer, editorial, and deep-web sources.
The choice between the two depends on whether LLM citation is your only question or one of several.
Where Evertune is strong
- Purpose-built for LLM citation tracking — clean, focused product
- Strong UI for citation share visualisation — easier to grok than a SQL query
- Established LLM monitoring methodology — they've thought hard about prompt diversity and citation extraction
- Lower commitment — narrower product = faster to onboard, easier to evaluate
If your only question is "where am I being cited (and not) by the LLMs," Evertune is the most direct answer.
Where Theia is built differently
| Dimension | Evertune | Theia |
|---|---|---|
| Scope | LLM citation across ChatGPT, Perplexity, Google AIO, Claude | Demand · Visibility · Sales · Perception across all major surfaces |
| Surfaces beyond LLM | None (focus is the moat) | Google SERP, Amazon, retailer pages, reviews, YouTube, Reddit, editorial, deep web |
| Sales integration | None | 1P (VC) + 3P (Stackline) |
| Perception extraction | None (citation only, not feature-level) | Feature × sentiment × trajectory across 100K+ snippets |
| B2B / deep web | Not in scope | 8,000+ classified deep-web sources |
| Strategy outputs | Citation dashboards | L1-L4 strategy briefs + content generation |
| Cross-language | Yes | Yes, with native-language extraction + harmonisation |
| MCP / natural language query | No | Yes |
| Pricing | ~$18k/month for 6 countries (LLM-only) | Tier 3 consumer brand: £6k/month for 4 countries (all 4 pillars) |
Where the genuine overlap is
Both Evertune and Theia track citation share in Google AI Overviews, ChatGPT, Perplexity, and Claude. Both produce per-keyword citation share leaderboards. Both can answer "is my brand cited for these queries?"
The difference is what surrounds the answer:
- Evertune: deep, focused, easy-to-buy LLM citation product
- Theia: LLM citation is one weekly refresh among many; the strategic value is the integration with Demand, Sales, and Perception
For a brand that just wants to know its LLM citation share, the surrounding integration is unnecessary cost. For a brand that wants to know "where am I losing share and why", the LLM citation share is one data point in an answer that needs all four pillars.
Should you have both?
It's reasonable. Evertune for the cleanest LLM citation view; Theia for the broader strategic context. This is a defensible stack if budget allows.
But for most brands, you'll get more strategic value from Theia's integrated view (LLM citation included) than from Evertune alone. The LLM citation share is more actionable when you can see it next to organic visibility, AI Overview rate of appearance, and the sentiment trajectory of the cited content.
Pricing comparison
- Evertune: ~$18,000/month for 6 countries (publicly cited rate)
- Theia Tier 3 consumer brand: £6,000/month for 4 countries (includes LLM citation tracking + all four pillars + L1-L4 strategy)
If LLM-citation-only is the scope, Evertune at the published rate is more expensive per surface than Theia at Tier 3. If broader scope is needed, the comparison is even more favourable to Theia.
What we'd want a fair comparison to include
- LLM citation share accuracy (same keywords, same period, do the numbers agree?)
- Citation source extraction quality (do both find the same source URLs?)
- Trajectory tracking (week-over-week citation share movement)
- Strategy integration (does the citation insight connect to anything else actionable?)
We're happy to run that test side-by-side for prospective clients. The fair comparison isn't price-per-license; it's strategic value delivered against the brand's actual question set.
