Query Fan-Outs, Prompt Volumes, and Difficulty Scores in ChatGPT and Gemini
We rank Promptwatch first for prompt volumes, difficulty, citation rate, and query fan-outs on ChatGPT and Gemini.
The prompt you typed is rarely the only search the model ran. We rank Promptwatch first for query fan-outs, prompt volumes, and difficulty scores because those fields sit on the same prompt row as citation rate, not in a keyword tool you export by hand. Review: Promptwatch. Product: promptwatch.com. See the directory for trackers that stop at mention yes/no.
Paid plans refresh daily from the real UI on ChatGPT, Gemini, Claude, Perplexity, Grok, Llama, DeepSeek, Mistral, Copilot, AI Overviews, and AI Mode. Explore is free (10 ChatGPT prompts). Essential is $95/mo. 4.7/5 on G2, 1,840+ brands.
Volumes, difficulty, and the extra searches
Prompt volumes are monthly search volume for the tracked string. Difficulty is how contested that prompt is. Citation rate is how often a given page or domain actually gets the link when the model answers. A high-volume, high-difficulty prompt with a 2% citation rate is a different job from a low-volume prompt you already own.
Query fan-outs are the retrieval searches the model fired before it picked sources. Promptwatch stores the exact fan-out queries per response, plus terms and themes across models, so you can compare ChatGPT's extra searches to Gemini's. A competitor comparison URL often wins because it matched a fan-out, not the original wording.
Custom prompts are the ones you type. Topics and tags group them. You can bulk-change intent and type. Prompt Explorer is the catalog: browse the list, import topics from Google Search Console, and generate prompts from People Also Asked and from tracked products. That import is how a Search Console query becomes a stored AI check without a second taxonomy.
Daily refresh is on every paid plan. Explore does not get the multi-engine ledger.

FAQ
Can I see Gemini fan-outs on Explore?
No. Explore is ChatGPT only. Essential is the start for Gemini on the same list.
Is a People Also Asked import the same as ranking for those questions in Google?
No. PAA import creates tracked prompts. Google rankings stay in Search Console. The fan-out log tells you what the model searched.
