Does Scrunch track Claude and Gemini on its entry plan?
No. Scrunch Core supports ChatGPT, Perplexity, Google AIO and Copilot; Claude, Gemini, Meta AI, Google AI Mode and Grok are listed on Enterprise. Proofsource includes Claude on the trial and in every plan's default four.
How often does Scrunch run each prompt?
Scrunch does not publish a cadence; it publishes a monthly response budget. At 125 prompts on 4 engines, 5,000 responses a month works out to about 10 reads of each prompt on each engine a month. Proofsource re-reads every question on every engine a plan picks, on the cadence it picks: daily or weekly.
Where Proofsource shines: 4 things it is built to do.
Each one is a mechanism: what runs, how often, and what would catch us out if it were not true.
The free trial is the real report.
The free trial asks 25 buyer questions on ChatGPT, Perplexity, Claude and Google AI Overviews, 2 scans a day apart, and hands back what a subscriber reads: which questions name you on which engine, who is named instead, and the pages each engine cited. No card, no call. One per company domain.
Every number arrives with the interval it was measured at.
Ask an engine the same question twice and you can get two answers, so one read is a draw, not a fact. We publish a 95% Wilson interval on every percentage and hold alerts until a change clears it. A tool that treats a single run as a finding will sell you progress on a day you did nothing.[2]
Four engines from the free trial, 4 on the price card.
ChatGPT, Perplexity, Claude and Google AI Overviews run side by side from the free trial upward, each priced per question on paid plans; Google AI Mode, Gemini, Microsoft Copilot, Grok, DeepSeek and Meta AI are enabled on a call. The questions are re-asked on their own on the cadence you pick: daily or weekly. The full history leaves as CSV or JSON over any date range, or through the REST API, so the record is yours.
Each gap names the page that beat you, then drafts the answer.
A gap carries the sources the engines cited instead of you. Then a draft built on what those pages have and yours does not, held for a human to approve, because nothing should publish itself in your name.
Already using Scrunch?
You do not have to choose on day one. Here is how teams run Proofsource beside Scrunch and decide on their own data.
Keep Scrunch running
Nothing about trying Proofsource needs you to stop Scrunch. Your history and reports there stay where they are.
Bring your questions across
Export or copy the prompts you track in Scrunch and add them as buyer questions in Proofsource, so both tools ask the same things.
Run both side by side
Read the two for the same days on your own domain. Where the numbers differ, Proofsource shows the answers and the pages each engine cited, so you can see why.
Keep what serves your team
Many teams keep one tool for reporting and another for fixes. Pick on your own evidence, not on a comparison page.

Where do the Scrunch facts on this page come from?
From Scrunch's own public pages, linked in the Sources list with the date we read them. We have not run Scrunch on a domain of our own, so no measured number on this page is theirs. If a row is out of date, tell us and we will change it.
Where each fact on this page comes from.
- Scrunch pricing, read Oct 5, 2026. Scrunch's own page; no third-party roundup is used as a source.
- Wilson score interval. The interval we put on every visibility percentage. Introduced by E. B. Wilson in 1927 and standard for binomial proportions, because it stays honest at small sample sizes and near 0% or 100% where the naive normal approximation breaks.
- Proofsource sampling: day-over-day change in which brands get named, same question one day apart. Perplexity 27%, ChatGPT 18%, Google AI Overviews 12%, Claude 9%. How we measure.
