Prefer tracks 5 AI engines on every plan: ChatGPT, Gemini, Google AI Overviews, Google AI Mode and Perplexity. Prefer Enterprise is a custom plan that adds every AI model you need, such as Claude, Microsoft Copilot, Grok, Meta AI, DeepSeek and Qwen. Self-serve plans differ on volume, never on which engines you get. *Last updated 3 October 2026* ## The engine list, plan by plan Prefer tracks the same engines on every self-serve plan, so the list does not change when the price does. Here is the full set as the docs and the [pricing page](https://tryprefer.com/pricing/) show it: | Engine | Starter, Growth, Scale | Enterprise | | - | - | - | | ChatGPT | Included | Included | | Gemini | Included | Included | | Perplexity | Included | Included | | Google AI Overviews | Included | Included | | Google AI Mode | Included | Included | | Claude | On Enterprise | Included | | Microsoft Copilot | On Enterprise | Included | | Grok | On Enterprise | Included | | Meta AI | On Enterprise | Included | | DeepSeek | On Enterprise | Included | | Qwen | On Enterprise | Included | | Any other AI model you need | On Enterprise | Included | **Every self-serve plan includes the same 5 engines; the tiers differ on volume, never on engine access.** Starter, Growth and Scale change how many prompts, competitors, articles, projects and seats you get. If you need Claude, Microsoft Copilot, Grok, Meta AI, DeepSeek, Qwen or any other model, [Prefer Enterprise](https://tryprefer.com/solutions/enterprise/) covers it as a custom plan; [book a demo](https://cal.com/javed-khatri-wlgmiv/30min) to scope it. ## Why Google counts twice Google AI Overviews and Google AI Mode are two separate engines in Prefer, not one. They look related, but they cite different pages. In [our September 2026 capture](https://tryprefer.com/learn/answers/ai-overviews-vs-ai-mode/) of 80 questions, only 32% of the pages AI Mode cited also appeared in the AI Overview for the same question. Gemini is a third, separate Google surface. So Prefer reports each one on its own row, and a win on one Google surface does not hide a loss on another. ## Where each engine shows up in the app **Every metric in Prefer splits per engine as well as blended, so you can catch a drop on one engine even when the overall number is flat.** You see the split in four places: 1. **Overview.** The Platform performance heatmap shows Visibility, Share of Voice and Citation Share per engine, side by side. 2. **Prompts.** Each prompt's detail page filters answers by engine, and View all chats shows the exact answer each engine returned. 3. **Competitors.** The Compare and Sources tabs both split by engine, so you can see which engines favor a rival and which cite you. 4. **Filter Bar.** On any Monitor page, pick one engine and every number on the page recomputes for that engine alone. This matters because the engines rarely agree. In Prefer's September 2026 study of 960 answers, 72.7% of the 1,329 cited sites were cited by just one of four engines, and only 29 sites were cited by all four. A single blended score would hide most of that. ## How to set your engines 1. **Pick engines during onboarding.** The wizard has an engines step. Leave all five on unless you have a reason not to. 2. **Run tracking.** Click Run tracking now in the top bar, or wait for the scheduled run. Each run sends every enabled prompt to every enabled engine. 3. **Read the heatmap.** Open Monitor, then Overview, and look for the engine where you are weakest. That is usually where the first action belongs.

A bigger plan buys more tracked prompts, competitors, articles, projects and seats. Only Prefer Enterprise adds engines, and it adds every other model you need, such as Claude, Microsoft Copilot, Grok, Meta AI, DeepSeek and Qwen. No. In Prefer a tracked prompt is one prompt in one country, and every enabled engine runs inside that one slot. Asking one question across all five engines uses one slot, not five. Countries are what multiply the count. Yes. Prefer's onboarding wizard has an engines step where you pick which answer engines to track. Each tracking run then sends every enabled prompt to every enabled engine, so turning one off simply removes it from the runs. ## Also asked as * What AI platforms does Prefer monitor? * Does Prefer cover ChatGPT, Gemini and Perplexity? * Which LLMs are included in each Prefer plan? ## Sources * [Prefer docs: AI answer engines Prefer measures across plans (captured 2026-10-03)](/docs/concepts/engines) * [Prefer Enterprise (our product)](https://tryprefer.com/solutions/enterprise/) * [Prefer docs: Quickstart (captured 2026-10-03)](/docs/get-started/quickstart) * [Prefer pricing FAQ: What counts as a tracked prompt?](https://tryprefer.com/pricing/) * [Prefer AI answer study, September 2026](https://tryprefer.com/data/ai-answer-study/) * [Prefer: AI Overviews vs AI Mode](https://tryprefer.com/learn/answers/ai-overviews-vs-ai-mode/) ## Related * [Does Prefer track Claude?](/docs/help/does-prefer-track-claude) * [Does Prefer track Microsoft Copilot?](/docs/help/does-prefer-track-microsoft-copilot) * [Does Prefer track DeepSeek and Qwen?](/docs/help/does-prefer-track-deepseek-and-qwen) * [What counts as a tracked prompt in Prefer?](/docs/help/what-is-a-tracked-prompt-in-prefer) * [Which AI engines do AI visibility tools track?](https://tryprefer.com/learn/answers/which-ai-engines-do-visibility-tools-track/) * [Prefer Enterprise: every AI model you need](https://tryprefer.com/solutions/enterprise/) * [Answer Engine Insights: per-engine views](https://tryprefer.com/platform/answer-engine-insights/) * [Which engines other tools include, by tier](https://tryprefer.com/learn/answers/which-ai-engines-do-visibility-tools-track/) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
