AI visibility monitoring & alerts that catch the drop before it hurts.

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.

Run-over-run comparison

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.

Typed drift events, every engine

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.

Morning feed, ready before the day

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.

Inside drift

How does drift detection work — every run, diffed, every shift an event.

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.

Drift events

Five signals, one feed

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.

Answer diffs

See the exact words that changed

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.

Inbox

The feed that replaces the fire drill

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 explained

What is AI answer drift — and why does it matter?

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.

Why it happens

Engines retrain — your rank shifts

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.

Why detection matters

The window to fix it is short

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.

Alert timing

When do alerts fire — and what do they contain?

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.

Alert timeline

Before and after, side by side

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.

FAQ

Questions, answered.

What is AI answer drift?+
AI answer drift is the change in how an engine responds to a category question between prompt runs — your brand losing a mention it used to have, slipping in position among cited sources, or a shift in the tone an engine uses to describe you. Mentionova diffs each run against the previous one and turns every change into a typed, timestamped event.
How does drift detection work?+
After each scheduled or manual run, Mentionova compares the new answer to the previous one for every prompt and every engine. Fields compared include mention presence, position rank, and sentiment score. Any field that changed becomes a drift event — typed as mention lost, mention gained, position improved, position declined, or sentiment shift — and surfaces in your feed.
When do alerts fire?+
Alerts land in your feed the next time a scheduled run completes after a change is detected. On a daily schedule that means the following morning. You can also trigger a manual run at any time to get an immediate read on any prompt.
Which drift events does Mentionova detect?+
Five: mention lost, mention gained, position improved, position declined, and sentiment shift. Each event is tagged gain, loss or neutral so you can scan a week's worth of changes and immediately see which way it went.
Can I see the old answer next to the new one?+
Yes. Run history is kept per prompt, and a drift event shows the before-and-after of the engine's answer — the exact phrase you lost and the competitor that took your place, highlighted in the diff.
Does drift detection work across all six engines?+
Yes. Drift is computed per engine, per prompt, so you can tell whether you slipped everywhere or just in the one engine your buyers happen to trust most.
How fast will I know if ChatGPT drops my brand?+
It depends on your run schedule. On a daily schedule you'll see the drift event the next morning after the run that caught it. You can also trigger a manual run of any prompt anytime you want an immediate read.
