See where competitors are named and you are not.
Competitor Comparison for AI Search
As a GEO tool, 99Visibility reads the AI answers your audit already got and counts how often each tracked competitor is named beside you: by platform, by prompt, and by position in the answer. You can track 1 competitor on Free, 1 competitor on Starter, 2 competitors on Growth and 3 competitors on Pro.
Comparing yourself to a competitor in AI search needs the same questions, the same engines and the same day. That is what this gives you: every number comes from the answers to your own prompts, in the same audit.
Adding a competitor costs no extra queries and no audits. The comparison is read from text the engines already returned.
Being named is not the same as being recommended. Answers to "best" questions read like ranked lists, so the comparison records who was named first and how much of the conversation each brand took, as well as who was named at all.

What you see
Mention rate, side by side
Your mention rate next to each competitor's, overall and on each platform, from the same set of answers.
Share of voice
Your share of all the times any tracked brand was named. An answer that names a competitor three times counts three.
Rank in the answer
Where you appear among the tracked brands in each answer that names you, averaged over those answers: 1 means you were named first every time. An answer that leaves a brand out gives it no rank, so read rank beside mention rate.
Prompt gaps
The prompts where a tracked competitor is named and you are not. Start there.
Trend
Mention rates across audits, so you see whether a gap is closing or growing.
What to do about it
A fix for the biggest gaps: check that your page can be fetched and read without JavaScript, then get onto the sources the engines cited.
How it works
- 1
Add competitors
Add each one with its name and website in competitor settings: 1 competitor on Free, 1 competitor on Starter, 2 competitors on Growth and 3 competitors on Pro.
- 2
Run an audit
Each answer is scanned for every competitor with the same matching used for your brand: spacing variants, possessives and their domain name.
- 3
Compare like with like
A competitor's mention rate is counted over the same answers as yours. A platform outside your plan is not shown as zero for anyone.
- 4
Read the ranking
The ranking orders every tracked brand, you included, by share of voice, with each brand’s average rank beside it. It does not use the visibility score, which exists only for your own brand.
- 5
Act on the gaps
Open the prompts where they are named, read the answers, check the sources cited, then work the fix list.
A comparison, worked through
6 prompts on all 6 platforms is 36 answers. 2 competitors are tracked.
Example output
| Brand | Answers naming it | Mention rate | Times named | Share of voice |
|---|---|---|---|---|
| You | 9 of 36 | 25% | 12 | 27% |
| Competitor A | 15 of 36 | 42% | 24 | 55% |
| Competitor B | 6 of 36 | 17% | 8 | 18% |
Illustrative numbers, computed the way the product computes them. Mention rate counts answers that name a brand; share of voice counts every time it is named.
From a real audit: who AI names first
On 15 October 2026 we audited Under Armour with Nike, Adidas and Puma as its tracked competitors, the 3 competitors the Pro plan allows. Five prompts a shopper types without naming a brand went to ChatGPT, Perplexity and Claude, so every brand was counted on the same 15 answers.
From a real audit
| Brand | Answers naming it | Named first | Share of brand mentions | Links to its own site |
|---|---|---|---|---|
| Nike | 14 of 15 | 13 | 45% | 1 |
| Adidas | 13 of 15 | 2 | 34% | 0 |
| Puma | 9 of 15 | 0 | 12% | 0 |
| Under Armour | 9 of 15 | 0 | 8% | 0 |
Mention rate alone hides most of the gap. Under Armour was named in 9 of the 15 answers, 60% of them, but it was never named first and took 8% of the brand mentions to Nike’s 45%.
The share moves by platform. Under Armour had 6% of the brand mentions on ChatGPT, 12% on Claude and 13% on Perplexity, and ChatGPT, which wrote the longest lists, supplied 118 of the 192.
The gap to act on is a prompt. On "best running shoes 2026" no platform named Under Armour, while ChatGPT named Nike, Adidas and Puma, in that order.
Counted from the saved answers the way the product counts share of voice and rank; "named first" is an answer in which a brand ranked 1. Gemini's answers in that run were cut short by a token limit on our side and are left out, and Google AI Overviews was not part of it.

Agent V is the assistant beside your dashboard. Ask it where a competitor is named and you are not, and it reads your audit answers and your own site to say which prompts and engines the gap sits on.
Adding a competitor to track comes to you as a card to confirm, like every change V proposes.
Anything that changes your account, like running an audit or adding a keyword, comes to you as a card to confirm. Nothing changes until you do, and V never edits your site. It runs on Anthropic's Claude models and is on every plan.
Who it is for
- Brands in a category where buyers ask AI for "the best" option and get a short list.
- Brands that are well known but rarely named first, where a mention count looks healthy and the ranking does not.
- Marketers who need to show where a competitor is ahead before asking for budget to close the gap.
What it does not do
- It does not give competitors a full visibility score. Accuracy and sentiment are measured against your facts and your name; competitors get mention rates, share of voice and rank.
- It does not say why an engine prefers a competitor. It shows where and how often; the sources an answer cites are the nearest thing to a reason, and only engines that search the web give them.
- It does not ask about competitors directly. Every prompt is yours, so the numbers describe the questions you care about.
- It does not see their traffic, ad spend or analytics.
- Names are matched as text, ignoring case. A brand named after a common word can be over-counted, so read the answers behind a surprising number.
- On Free it measures 1 competitor, the first one listed.
Questions
What does share of voice mean in AI search?
Here it has a precise meaning: your mentions as a share of all mentions of the brands you track, in the answers to your prompts. An answer that names a competitor three times and you once gives them three of the four. In our sportswear audit Nike took 45% of the brand mentions across 15 answers and Under Armour 8%.
How many competitors can I track?
1 competitor on Free, 1 competitor on Starter, 2 competitors on Growth and 3 competitors on Pro. The limit is checked on our server when you add one.
How do I see which competitors AI recommends instead of me?
Add them as competitors and run an audit. The prompt gaps list every prompt where a tracked competitor is named and you are not, and each answer is there to read in full. A brand you do not track is not counted, so read a few answers to see who else appears.
Why does a competitor lead on one platform and not another?
The engines answer differently. ChatGPT and Claude decide per prompt whether to search, so some of their lists come from training data, while an answer that searches builds its list from the pages it fetches. A lead in answers from memory changes only with a newer model; a lead in answers that searched can change when the cited pages do.
Does tracking a competitor use up audits?
No. Competitors are counted in the answers your audit already returned; no extra queries are sent.
Does tracking competitors change my score?
No. Share of voice and rank are shown beside your visibility score and are not part of it.
Why do mention rate and share of voice disagree?
Mention rate counts answers that name a brand at all. Share of voice counts every mention, so a brand named three times in one answer gains more of it.
