LLMrefs is an AI search analytics platform founded in 2024 that takes a keyword-first approach to AI visibility tracking. Instead of asking users to define prompts manually, LLMrefs uses a 4.5 million conversation dataset to generate prompts based on what people actually ask AI. LLMrefs covers 11 AI engines, one of the widest coverages available.
If you're evaluating AI visibility tools, here's a detailed breakdown of how LLMrefs works, what LLMrefs costs, and how LLMrefs compares to Mentionable.
How does LLMrefs track AI visibility?
LLMrefs flips the typical AI visibility workflow. You enter keywords (not prompts), and LLMrefs automatically generates relevant prompts based on its 4.5M ChatGPT conversation dataset. You track what people actually ask, not what you think they ask.
LLMrefs covers 11 AI engines: ChatGPT (including GPT-5), Google AI Overviews, Google AI Mode, Gemini, Perplexity, Claude, Grok, Copilot, Meta AI, and DeepSeek. That breadth is one of the widest available among AI visibility platforms.
LLMrefs' keyword-based tracking lets you enter keywords and generates "fan-out prompts" based on real conversations. Tracking a keyword like "email marketing" gives visibility across dozens of actual prompts people use.
The ChatGPT Prompts Database is free to access, containing 4.5M real conversations from ChatGPT, Gemini, Perplexity, and other AI chatbots. You can explore what people ask in any category before committing to paid tracking.
LLMrefs also offers geo-targeting across 20+ countries and 10+ languages, plus citation and sentiment analysis.
How much does LLMrefs cost in 2026?
LLMrefs offers a free tier plus paid plans. The free tier gives access to the ChatGPT prompts database (no tracking included). LLMrefs Pro costs $79/month for 50 keywords, 11 AI engines, and 500 prompts per month. LLMrefs Enterprise has custom pricing.
| Plan | Price | Keywords | Prompts | AI Engines |
|---|---|---|---|---|
| Free | $0 | N/A | N/A (database access only) | N/A |
| Pro | $79/month | 50 | 500/month | 11 |
| Enterprise | Custom | Custom | Custom | 11 |
The free database access requires no credit card. For actual visibility tracking, LLMrefs Pro at $79/month is competitive given the 11-engine coverage.
What does LLMrefs do well?
LLMrefs' 4.5M prompt dataset means tracking is based on queries people actually use, not assumptions or guesses. That data-driven approach reduces the risk of tracking irrelevant prompts.
LLMrefs covers 11 AI engines including ChatGPT (GPT-5), Claude, Gemini, Grok, and DeepSeek. Few AI visibility tools match that breadth of coverage.
LLMrefs' keyword-first workflow is efficient. Enter keywords, get auto-generated prompts. Less manual prompt research, more automated discovery based on real conversation patterns.
The free ChatGPT prompts database is genuinely valuable for research. Exploring what people actually ask in any category, before committing to paid tracking, helps validate whether AI visibility matters for a specific niche.
