Most brands worry about whether AI mentions them at all. But there's a problem nobody talks about: what happens when AI does mention you — and says something terrible?
We analyzed sentiment data for 1,159 brands across ChatGPT, Claude, Gemini, and Perplexity. The findings are uncomfortable: among brands that AI actually mentions, more than half receive neutral or negative sentiment. Some highly visible brands are being actively harmed by the way AI describes them.
The hidden danger: Visibility without positive sentiment is worse than invisibility. When AI mentions your brand 100% of the time but with a sentiment score of 5/100, every AI user is hearing a negative opinion of your company.

Only 24% of mentioned brands receive genuinely positive AI sentiment
The Brands AI Likes Least
These brands are visible to AI — meaning they get mentioned regularly in recommendations and comparisons. But the tone is consistently negative, dismissive, or critical. AI describes them with hedging language, unfavorable comparisons, or outright criticism.
Brands With Worst AI Sentiment
Visible to AI but viewed negatively -- high visibility with low sentiment is worse than invisibility
| # | Brand | Visibility | Sentiment | Role | Industry |
|---|---|---|---|---|---|
| 1 | Letgo | 83% | 5 | Alternative | Local Marketplace |
| 2 | Hexo | 25% | 7 | Primary | Static Site Generator |
| 3 | Feedzai | 17% | 8 | Primary | Financial Technology |
| 4 | Collabora Online | 42% | 10 | Primary | Open-Source Office Suite |
| 5 | Camunda | 25% | 12 | Primary | Process Automation |
| 6 | Olark | 33% | 13 | Primary | Live Chat Software |
| 7 | Appian | 58% | 14 | Primary | Low-Code App Development |
| 8 | Salesflare | 8% | 15 | Primary | CRM Software |
| 9 | Varsity Tutors | 42% | 16 | Primary | Online Tutoring |
| 10 | Fabletics | 25% | 17 | Primary | Fitness Apparel |
Why does this happen? AI sentiment reflects training data. If your brand is frequently mentioned in complaint threads, negative reviews, or unfavorable comparisons, AI learns to describe you in those terms. Letgo's score of 5/100 likely reflects its rocky merger with OfferUp and subsequent user complaints that dominated online discussions.
The Brands AI Loves Most
At the other end of the spectrum, these brands have earned genuinely enthusiastic AI descriptions. When AI mentions them, it uses positive language, recommends them as primary picks, and speaks about them with confidence.
Brands With Best AI Sentiment
These brands earn genuinely positive treatment from AI engines
| # | Brand | Visibility | Sentiment | Industry |
|---|---|---|---|---|
| 1 | Signal | 75% | 98 | Encrypted Messaging |
| 2 | Ethique | 75% | 95 | Personal Care |
| 3 | People Tree | 33% | 95 | Fair Trade Fashion |
| 4 | Coca-Cola | 100% | 89 | Beverages |
| 5 | Veja | 92% | 86 | Ethical Sneakers |
| 6 | Zoom | 100% | 85 | Team Communication |
| 7 | Hydro Flask | 92% | 85 | Insulated Bottles |
| 8 | Toggl Track | 92% | 83 | Time Tracking |
| 9 | Shopify | 100% | 83 | E-commerce Platform |
| 10 | Teladoc Health | 100% | 81 | Telemedicine |
Notice a pattern? The brands with the best sentiment tend to have strong, unambiguous positioning. Signal is the privacy messenger. Ethique is the sustainable beauty brand. Veja is the ethical sneaker company. When a brand owns a clear narrative, AI describes it with confidence and positivity.
Which AI Engine Is the Harshest Critic?
Not all AI engines judge brands equally. Gemini is the most generous with praise, while Claude is the most critical. The gap between them is significant — a brand might get a warm recommendation from Gemini and a lukewarm one from Claude.
Average Sentiment by AI Engine
Gemini is the most generous; Claude is the harshest critic
The 14-point gap between Gemini (64.9) and Claude (50.5) means the same brand can be described as "excellent" by one engine and "adequate" by another. This isn't a small difference — it can change whether a user clicks through to your site or chooses a competitor.
The Visibility-Sentiment Correlation
There's good news buried in the data: higher visibility correlates with better sentiment. Brands in the strong visibility tier (60-100%) have an average sentiment of 65/100, compared to just 42/100 for weak brands (1-29%).
This creates a virtuous cycle — or a vicious one. Brands that AI already likes tend to get mentioned more, reinforcing their positive image. Brands with poor sentiment get mentioned less often, but when they do appear, the tone stays negative.

What You Should Do About AI Sentiment
1. Check your sentiment score, not just visibility
A high visibility score with low sentiment means AI is actively working against you. You need to know both numbers. Check your brand's AI sentiment free.
2. Audit what AI actually says about you
Read the actual AI responses, not just the metrics. Sometimes AI uses your brand as a negative comparison point ("unlike X, which has had issues..."). Understanding the narrative is critical.
3. Fix the source, not the symptom
AI sentiment reflects your broader online reputation. If forums, reviews, and articles describe your brand negatively, AI will too. Address the root causes — customer complaints, PR issues, outdated negative content — to improve AI sentiment over time.
4. Own your category narrative
Brands with the best sentiment scores have clear, unambiguous positioning. Signal = privacy. Ethique = sustainable beauty. Define what you are so clearly that AI can describe you confidently.
