Alerts for the changes that are real, not the daily noise.
Alerts in Proofsource tell you when something meaningful changes in how ChatGPT, Perplexity, Claude and Google AI Overviews answer about your brand: a real drop in mention rate, a new wrong claim, a competitor entering your answers or a hostile source being cited. A visibility alert only fires when the change clears the 95% confidence range.
| Alert | Engine | Why it fired | Status |
|---|---|---|---|
| Mention rate dropped from 48% to 21% | Perplexity | 95% ranges no longer overlap | Significant |
| New wrong claim: “no free plan” | ChatGPT | Contradicts a confirmed fact | Open |
| Competitor named on 3 of your questions | Google AI Overviews | New brand in your answers | Open |
A visibility alert fires only when the change is bigger than the noise.
AI answers move every day. The same question can name you on Monday and not on Tuesday. Proofsource puts a 95% Wilson range on the before and after, and sends a visibility alert only when the two ranges stop overlapping. Smaller moves are recorded in your history and stay out of your inbox.
- Before and after, each with its 95% range
- Watches for drops, rises or both
- No alert for a move the sample cannot support
Visibility, accuracy, competitors and sources, watched for you.
Mention rate is one signal. Proofsource also raises a claim alert when an answer contradicts a fact you confirmed, and flags it when a page attacking your brand starts being cited, when a competitor changes a page that matters, and when a new page names you, a competitor or your category.
- Claim alerts with the wrong sentence attached
- Daily checks of competitor sites and new sources
- Hostile citations flagged the first time they appear
| Signal | Checked | Flagged when |
|---|---|---|
| Mention rate | Every scan | The change clears the 95% ranges |
| Wrong claims | Every scan | An answer contradicts a confirmed fact |
| Hostile citations | Every scan | A cited page that attacks you appears |
| Competitor sites | Daily | A competitor changes a page that matters |
| New sources | Daily | A new page names you, a competitor or your category |
Every alert says what changed, why it matters and where to look.
Significant visibility changes arrive by email and every alert sits in the dashboard with the answers behind it. Each one names the engine, the questions involved and the evidence, so you can act on it without opening five screens first. Dismiss an alert when it is handled, or reopen it later.
- Email for significant visibility changes
- Every alert links to the captured answers
- Dismiss and reopen, so the list stays honest

Questions buyers ask
How do Proofsource alerts avoid false alarms?
Each visibility alert compares the before and after with a 95% Wilson confidence range on each. It fires only when the two ranges do not overlap, which means the change is unlikely to be normal day-to-day variation in AI answers.
What can Proofsource alert me about?
Alerts cover significant drops or rises in mention rate and answers that contradict a fact you confirmed. Proofsource also flags a hostile page being cited about you, changes to competitor websites, and new pages that name your brand, a competitor or your category.
How are alerts delivered?
Significant visibility changes are sent by email, and every alert appears in the dashboard with the answers behind it. You can dismiss an alert once it is handled and reopen it later.
Why do AI answers change from day to day?
AI engines sample their answers, refresh what they retrieve from the web and update their models, so the same question can produce a different shortlist on different days. That is why Proofsource measures over many answers and puts a range on every number.
