Mentionova diffs every prompt run against the last and alerts you the morning an engine drops, demotes, or cools on you — across ChatGPT, Perplexity, Claude, Gemini, Google AI, and Reddit. Track AI visibility metrics for every prompt and see exactly what changed, word by word.
Every prompt run is compared row by row against the previous one — mention presence, position rank, and sentiment score. Any field that changed is highlighted instantly, producing a typed diff, not a raw number.
Each change produces a named event — position declined, mention gained, sentiment shift — tagged loss, gain or neutral and labelled with the engine, the prompt, and the magnitude of the change. See content optimization signals alongside every event.
Drift events land in one shared inbox the morning the run that caught them completes — priority-sorted, engine-labelled, and linked to the exact before-and-after diff so you act immediately, not in the quarterly review. See the full daily brief alongside your alerts.
Mentionova compares each completed prompt run field by field against the previous one — mention presence, position among cited sources, and sentiment score. Any field that differs becomes a typed, tagged event surfaced in your feed before the day starts. AI visibility tracking ties every event back to the underlying metric trend.
Each run is compared with the previous one and emits typed events — mention lost, mention gained, position improved, position declined, sentiment shift — tagged gain, loss or neutral so a glance tells you whether the week went your way. Filter by engine, event type or time window.
Not just a score that dipped — the actual before-and-after of how the engine describes you, with the phrase you lost and the competitor that took your place highlighted. Scrub back through any prompt's history to see when the wording turned.
Drift events, new citations and milestones land in one inbox per workspace, so the whole team sees the same timeline — and big losses surface the morning they happen, not in the quarterly review.
AI answer drift is any change in how a large language model responds to a category query between runs — losing a mention, slipping in position among cited sources, or a shift in the tone an engine uses to describe your brand. Left undetected, drift silently costs pipeline before it ever shows up in a metric.
AI engines like ChatGPT, Perplexity, Claude, Gemini, Google AI, and Reddit continuously update which sources they weight and how they phrase answers. A competitor earning new citations, a news cycle shifting sentiment, or a model update can all move you without any action on your part.
When Gemini stops mentioning you in "best checkout tools", leads coming from AI-assisted searches drop — but the signal rarely surfaces before the next quarter. Daily drift monitoring gives you the event the morning it happens, when content and citation fixes can still recapture the position. Pair with AI content optimization to act on every alert.
Alerts fire the next time a scheduled run completes after drift is detected — on a daily schedule that means the following morning, before your day starts. Each alert links to the exact before-and-after diff, the engine, the prompt, and the magnitude of the change, so you know what happened and where in under thirty seconds.
Mentionova keeps the full answer from every run. When drift fires, the event links to the exact before-and-after of what the engine said — the phrase you lost, the rival that filled the gap, the run it happened on. One click shows you the diff, not a metric.
