The short answer
LLM Scan, Otterly.AI and Peec AI all run the questions your buyers ask through AI assistants and record whether your brand is mentioned, where it ranks and which sources get cited. Otterly.AI and Peec AI re-check answers every day and cover more assistants on their entry plans. LLM Scan has the lowest entry price, re-checks weekly on Starter and PRO, and puts Google rankings next to AI answers in one weekly report with 3 fixes. If you need daily data across many assistants, start with Otterly.AI or Peec AI. If you want an affordable weekly view of AI answers and Google in one place, start with LLM Scan.

Where LLM Scan is different
- Price to start. LLM Scan Starter costs $19 per month, against €29 for Otterly.AI Lite and €85 for Peec AI Starter.
- Google and AI in one report. Every LLM Scan plan tracks your Google rank and AI Overview citations for your keywords, next to the AI answers for the same prompt set, in one weekly report.
- A weekly fix list. Each report ends with the 3 things to fix next.
- A free technical scan without an account. It checks whether AI crawlers such as GPTBot and ClaudeBot can read your site: robots.txt, llms.txt, sitemap, structured data and semantic HTML.
- Agents that act on the plan. On Enterprise, an MCP-compatible agent can read the Playbook, save drafts and report progress with a scoped workspace key.
Where Otterly.AI and Peec AI are ahead
- Cadence. Both re-check answers daily on every plan. LLM Scan re-checks weekly on Starter and PRO, twice a week on Agency and daily on Enterprise.
- Assistant coverage. Otterly.AI Lite already covers 4 AI search engines, and Peec AI Starter lets you choose 3 models. LLM Scan covers 1 assistant on Starter and 2 on PRO and Agency. Claude and Gemini need Enterprise. Microsoft Copilot and Google AI Mode are not tracked.
- Seats. Both include unlimited users. LLM Scan includes 1 seat on Starter, 2 on PRO and 5 on Agency.
- Prompt volume. At similar prices, Otterly.AI and Peec AI include more prompts on their higher plans.
How to choose
- Pick LLM Scan if you are a small team or a single brand, want to start for under $20, and care about Google rankings as much as AI answers.
- Pick Otterly.AI if you want daily data on ChatGPT, AI Overviews, Perplexity and Copilot from the first plan, with unlimited team members.
- Pick Peec AI if you need more prompts, daily tracking and deeper analytics across several projects, and the budget starts at €85 per month.
