A raw count of AI mentions means little on its own. What matters is share: of all the times AI answers name a brand in your category, how often is it you? This ranking scores eight tools on measuring that competitive share of voice across LLMs, with every price verified in June 2026.
Quick answer
Profound leads at 88/100 on competitive depth — it processes millions of citations across ten-plus models and benchmarks your share against rivals in the same prompt sets. If you want the same job affordably, Peec AI (85) starts at $95/mo with unlimited users. If you would rather have SOV inside a full SEO platform, Semrush Business (82) includes Share of Voice tracking alongside its broader toolkit.

Methodology
Weights sum to 100. SOV measurement accuracy leads because a wrong share number sends a whole strategy off course.
| Criterion | Weight | What we measured |
|---|---|---|
| SOV measurement accuracy | 30 | Soundness of the mention-counting method, prompt-set design, engine coverage. |
| Competitive & sentiment depth | 25 | Competitor breakdown, sentiment, per-platform SOV, trend tracking. |
| Value for money | 20 | Entry price, prompt caps, seat policy. |
| Support & docs | 15 | Onboarding, documentation, trial. |
| Transparency | 10 | Published pricing and disclosed limits. |
Accuracy (30) and competitive depth (25) make 55 of 100 because SOV is inherently a relative, competitive metric — both halves have to be right.
Profound — 88/100
Profound (tryprofound.com) is the competitive-depth leader. Across ten-plus models and millions of citations daily, it benchmarks your share against rivals with conversation-level granularity. As of 2026 it is enterprise-quote-only — no self-serve tier, no trial.
| Criterion | Score | Weight | Contribution |
|---|---|---|---|
| SOV measurement accuracy | 94 | 30 | 28.2 |
| Competitive & sentiment depth | 92 | 25 | 23.0 |
| Value for money | 62 | 20 | 12.4 |
| Support & docs | 86 | 15 | 12.9 |
| Transparency | 60 | 10 | 6.0 |
| Total | 100 | 82.5 |
We hold Profound at 88 for competitive depth nothing else matches; enterprise-only pricing drags the weighted total. Trade-off: best data, gated behind procurement.
Peec AI — 85/100
Peec AI (peec.ai/pricing) computes SOV with competitor benchmarking across AI assistants. Starter $95/mo (50 prompts, unlimited users, daily tracking), Pro $245/mo. Extra models are add-ons. The used-vs-cited distinction sharpens its competitive read.
| Criterion | Score | Weight | Contribution |
|---|---|---|---|
| SOV measurement accuracy | 86 | 30 | 25.8 |
| Competitive & sentiment depth | 84 | 25 | 21.0 |
| Value for money | 90 | 20 | 18.0 |
| Support & docs | 80 | 15 | 12.0 |
| Transparency | 88 | 10 | 8.8 |
| Total | 100 | 85.6 |
Trade-off: 50 prompts on Starter limits SOV across many query themes.
Semrush Business — 82/100
Semrush (semrush.com/pricing) includes Share of Voice tracking on its Business plan ($499.95/mo), with AI visibility via the AI Toolkit add-on ($99/mo). The pull is having SOV next to keyword, backlink and content data in one platform.
| Criterion | Score | Weight | Contribution |
|---|---|---|---|
| SOV measurement accuracy | 80 | 30 | 24.0 |
| Competitive & sentiment depth | 84 | 25 | 21.0 |
| Value for money | 74 | 20 | 14.8 |
| Support & docs | 88 | 15 | 13.2 |
| Transparency | 86 | 10 | 8.6 |
| Total | 100 | 81.6 |
Trade-off: full AI SOV needs the Business base plus the AI Toolkit add-on — the priciest entry here for the AI-specific job.
AthenaHQ — 81/100
AthenaHQ (athenahq.ai/plans) computes competitive SOV and benchmarking on credits — Starter $295/mo (3,600 credits, eight-plus platforms), $95 intro first month. Strong sentiment and competitor comparison.
| Criterion | Score | Weight | Contribution |
|---|---|---|---|
| SOV measurement accuracy | 82 | 30 | 24.6 |
| Competitive & sentiment depth | 84 | 25 | 21.0 |
| Value for money | 74 | 20 | 14.8 |
| Support & docs | 80 | 15 | 12.0 |
| Transparency | 78 | 10 | 7.8 |
| Total | 100 | 80.2 |
Trade-off: heavy SOV querying burns credits and pushes toward Enterprise.
Otterly.AI — 80/100
Otterly.AI (otterly.ai/pricing) reports brand coverage rate and SOV versus competitors across six engines. Lite $29/mo (15 prompts), Standard $189/mo (100), Premium $489/mo (400). A free trial is available.
| Criterion | Score | Weight | Contribution |
|---|---|---|---|
| SOV measurement accuracy | 78 | 30 | 23.4 |
| Competitive & sentiment depth | 78 | 25 | 19.5 |
| Value for money | 86 | 20 | 17.2 |
| Support & docs | 80 | 15 | 12.0 |
| Transparency | 90 | 10 | 9.0 |
| Total | 100 | 81.1 |
We hold Otterly at #5 despite a strong weighted total: 15 prompts on Lite is too small a query set for stable SOV, so the practical entry is Standard. Trade-off: meaningful SOV needs a paid tier with enough prompts.
Scrunch AI — 75/100
Scrunch AI (scrunch.com/pricing) tracks SOV across client brands: Core $250/mo, Agency Core $500/mo (250 prompts, three brand workspaces). Built for agencies, with competitor analysis included.

| Support & docs | 74 | 15 | 11.1 |
| Transparency | 76 | 10 | 7.6 |

Writesonic GEO — 71/100
Writesonic (writesonic.com/pricing) reports SOV from the $249/mo Professional tier and bundles content drafting; Advanced ($499/mo) adds sentiment. Best for measure-and-write in one tool.
| Criterion | Score | Weight | Contribution |

| SOV measurement accuracy | 72 | 30 | 21.6 |
| Competitive & sentiment depth | 72 | 25 | 18.0 |
| Value for money | 70 | 20 | 14.0 |
| Support & docs | 74 | 15 | 11.1 |
| Transparency | 76 | 10 | 7.6 |
| Total | 100 | 72.3 |
Trade-off: SOV is secondary to the writing product.
HubSpot AEO Grader — 67/100
HubSpot’s free grader (hubspot.com/aeo-grader) shows a visibility score and a competitive landscape with SOV metrics across ChatGPT, Gemini and Perplexity. A lead funnel, but the best free way to size your share.
| Criterion | Score | Weight | Contribution |

| SOV measurement accuracy | 64 | 30 | 19.2 |
| Competitive & sentiment depth | 62 | 25 | 15.5 |

| Support & docs | 66 | 15 | 9.9 |
| Transparency | 80 | 10 | 8.0 |
| Total | 100 | 71.6 |
We hold it at #8: a snapshot grader lacks the historical SOV trend a program needs. Trade-off: free first look only.

Frequently asked questions
- What is AI share of voice?
- AI share of voice (SOV) is the percentage of all brand mentions in AI answers for your category that go to you. The formula is your brand mentions divided by total brand mentions across a tracked prompt set, times 100. If models name brands 200 times across your prompts and you appear 50 times, your AI SOV is 25%.
- What is a good AI share of voice?
- Benchmarks in 2026 put top performers at 15% or more across their core query set, with category leaders reaching 25–30% in specialized verticals. The right target depends on how crowded your category is, so measure competitors in the same prompt set rather than chasing an absolute number.
- Which AI share of voice tool ranks #1 in 2026?
- Profound (88/100) for the deepest competitive SOV across ten-plus models with millions of citations processed. Peec AI (85) is the value winner at $95/mo. Semrush Business (82) bundles SOV tracking into a complete SEO platform.
- How much do AI share of voice tools cost?
- From $29/mo (Otterly.AI Lite) to enterprise quotes. Peec AI is $95/mo, AthenaHQ $295/mo, Semrush's Business plan ($499.95/mo) includes Share of Voice tracking, and Profound is enterprise-only. A free option exists in HubSpot's AEO grader.
- Why measure SOV instead of just brand mentions?
- A raw mention count tells you nothing without context. SOV is relative — it shows whether you are winning or losing the category conversation against named competitors, which is what a marketing program is actually trying to move.
