- The five categories that matter: engines covered, prompt panel size, run frequency, alerting, and per-engine breakdown.
- Optymia covers 7 engines from $39.99/mo — most competitors gate multi-engine to $99+ tiers.

What is LLM brand mention monitoring?
LLM brand mention monitoring is a scheduled service that queries large language models with a fixed set of prompts, parses the answers for brand mentions (yours and your competitors'), and stores the results as a time-series so you can see share-of-voice trends and get alerts on new or lost mentions.
It is different from social listening (Twitter, Reddit) — LLM monitoring watches the actual answer that a buyer sees when they open ChatGPT, not the training-corpus source.
Why LLM mentions matter more than social mentions in 2026
A buyer researching "best CRM for SaaS startups" now opens ChatGPT before they open Google. If ChatGPT's answer names three vendors and you are not one, you never get the pitch. Social mentions are lagging indicators of awareness; LLM mentions are the point of purchase.
Perplexity now handles 500M queries/month; ChatGPT Search handles ~2B. Every one is a chance for your brand to be named or skipped.
What to look for in an LLM brand mention monitoring tool
Engines covered — ChatGPT and Perplexity are table stakes. Gemini, Claude, Copilot, and Grok separate serious tools from the demos.
Prompt panel size — anything under 20 prompts is not a signal, it is a demo. Look for 25+ per brand.
Run frequency — weekly is standard; anything less misses index drift.
Alerting — email is minimum; Slack, webhook, and Zapier separate the pros.
Per-engine breakdown — averages hide the truth. You need to see Claude and Perplexity side-by-side because they behave completely differently.

Optymia LLM brand mention monitoring — setup walkthrough
1) Add your brand + root domain in the dashboard. 2) Auto-generate or paste a 25-prompt panel. 3) Add up to 3 competitor brands to track on the same panel. 4) Pick engines (all 7 included on Starter). 5) The Monday cron runs the panel and writes to the history table.
Alerts fire when a new mention appears (Slack ping with the raw answer excerpt), when a mention is lost (investigate — did the engine reindex? did a competitor publish a listicle?), and when a competitor overtakes you on any single engine.
Building it yourself vs. buying
Build cost: one engineer week for the happy path, one full engineer month for the edge cases (footnote parsing, link-card extraction, partial-brand-name matching, engine rate limits, proxy management, Slack integration). Then ongoing maintenance every time an engine changes its response format.
Buy cost: $39.99/mo. The math is not close for any team under 50 people.
Frequently Asked Questions
What is LLM brand mention monitoring?
LLM brand mention monitoring is a scheduled service that queries large language models with a fixed prompt panel and tracks whether your brand is mentioned in the answers. It's the AI-era replacement for social-listening tools like Mention or Brandwatch.
Which LLMs should I monitor?
For B2B in 2026: ChatGPT, Perplexity, Gemini, Claude. Add Google AI Overviews if your ICP is enterprise, and Copilot if you sell into Microsoft-heavy orgs. Grok matters for consumer/political brands.
How is LLM monitoring different from social listening?
Social listening watches Twitter, Reddit, and news for mentions of your brand — lagging indicators of awareness. LLM monitoring watches the actual answer a buyer sees when they research inside ChatGPT — the point of purchase.
Can I monitor competitors with the same tool?
Yes — every serious LLM monitoring tool lets you add competitor brands to the same prompt panel so you get share-of-voice comparisons per engine. Optymia includes 3 competitors on Starter and 10 on Growth.

Otterly Lite is $29/mo (15 prompts, 4 engines). Optymia Starter is $39.99/mo (25 prompts, 7 engines). Profound Starter is $99/mo (ChatGPT only). Enterprise tiers are $400–$1000+/mo across all vendors.
