Know exactly how the answer engines talk about your brand.
Rankings told you where you sat in ten blue links. But when ChatGPT, Gemini and Perplexity write the answer, the only question that matters is whether they name you at all. cloro measures your mention rate, citation rate and share of voice across every engine — and tracks how they move week over week.
Share of voice — "project management software"
last 7 daysThree numbers that define AI visibility
Being visible in an answer engine isn't one thing. cloro breaks it into three measurable signals, computed the same way across every engine so the numbers actually compare.
Mention rate
Out of every prompt where your category comes up, how often does the engine name your brand at all? This is the base layer of presence — the answer to "do they even know I exist?"
Citation rate
When the engine backs its answer with sources, how often is one of them your domain? A mention is reputation; a citation is a click-path and a trust signal the engine is passing along.
Share of voice
Across the whole competitive set, what fraction of all brand mentions are yours? Share of voice turns raw counts into a single, rank-able position against the rivals the engines actually recommend.
The answer is the new front page.
A growing share of buying research never touches a results page. People ask an assistant, read one synthesized paragraph, and act. If your brand isn't inside that paragraph, you were never in the room — and no rank-tracking dashboard would ever have told you.
- Mentions and citations live inside prose, not in a ranked list — you can't parse them with a classic SERP tool
- Every engine phrases the same answer differently, so a single spot-check tells you nothing
- Answers drift weekly as models and their sources change; visibility is a moving target
- Your competitors are being recommended in answers you never see
Illustrative mention rate for one brand — the same prompt set, measured per engine. Real gaps this wide are common.
One brand looks different in every model
A brand that dominates ChatGPT can be almost invisible in Grok. cloro runs the identical prompt set through every engine so you see the whole picture — and know precisely where to spend your optimization effort.
Normalized, comparable scores
Mention, citation and share-of-voice are computed identically per engine, so a 60% in Gemini means the same thing as a 60% in Perplexity.
Drift detection over time
Re-run your prompt set on a schedule and cloro stores each snapshot. Diff any two periods to see exactly which engine moved, and by how much.
Prompt-level breakdown
Drill from a headline share-of-voice number down to the individual prompts where you were named — or conspicuously left out.

Visibility as a single JSON object
Pass a brand, a prompt set and the engines you care about. cloro runs the answers, resolves brand mentions and citations, and returns computed visibility metrics — ready to store, chart or alert on. No parsing prose yourself.
- Per-engine mention and citation rates in one response
- Competitor share of voice resolved from the same answers
- Period-over-period delta so change is one field away
- Markdown output too, when you want the raw answers as evidence
How a visibility program runs on cloro
Define your brand set and prompts
List your brand, your competitors and the buyer questions where you want to show up. This prompt set becomes the fixed yardstick every snapshot is measured against.
cloro queries every engine
On demand or on a schedule, the same prompts fan out to ChatGPT, Gemini, Perplexity, Copilot and Grok. Rendering, rotation and retries are handled upstream.
Mentions and citations get resolved
Every answer is scanned for brand names and source domains, then rolled up into mention rate, citation rate and share of voice — normalized per engine.
Snapshots stack into a trend
Each run is stored with its timestamp. Diff any two periods to see which engine moved you up, which dropped you, and whether your optimization work actually landed.
AI visibility, explained
What's the difference between mention rate and citation rate?
Mention rate is how often an engine names your brand anywhere in its answer — pure presence. Citation rate is how often the engine links your domain as a source when it shows its references. You can be mentioned without being cited, and occasionally cited without being named in the prose, so cloro tracks both separately.
How is share of voice calculated?
For a given prompt set and competitive set, share of voice is your total brand mentions divided by all brand mentions across the group. It turns raw counts into a single percentage you can rank and trend, so "we're at 31%, up 4 points" is a sentence a stakeholder understands.
Which engines can you measure?
ChatGPT, Gemini, Perplexity, Copilot and Grok on the answer-engine side, plus Google AI Overview and AI Mode. The identical prompt set runs through each one, so per-engine scores are directly comparable.
How do I track visibility over time?
Re-run the same prompt set on a schedule. cloro stores every run as a timestamped snapshot, and the API returns a period-over-period delta out of the box, so charting a trend or firing an alert when your share of voice drops takes one field, not a data pipeline.
Do I need my own model accounts or proxies?
No. You authenticate with a single cloro API key. Fetching the answers, rendering, rotation and retries all happen on our side, and you're billed only for successful calls.
