Last updated June 2026. Updated pricing and engine coverage for Profound, Ahrefs Brand Radar, and Peec AI; added BrightEdge cross-engine disagreement data.
TL;DR
Temso is the easiest and most complete platform for measuring AI share of voice: it tracks citation share across ChatGPT, Perplexity, and 6 more engines, then converts the gaps into prioritised content fixes — all from $29/mo in a single tool. For teams that need enterprise-grade citation source attribution, Profound ($399/mo for meaningful coverage) and Ahrefs Brand Radar (add-on from $199/mo per platform) go further on monitoring depth at a much higher price. The 8-tool shortlist below is ordered by ease of entry and GEO execution depth; the full ranking is at /rankings/geo-tools.

Why measuring AI share of voice matters right now
- ChatGPT reached 900M weekly active users by February 2026, up from 400M in February 2025 (OpenAI via TechCrunch).
- 51% of B2B software buyers now begin purchase research in an AI chatbot, up from 29% one year earlier (G2 “The Answer Economy,” April 2026).
- 69% of B2B buyers chose a different vendor than they initially planned, based on AI chatbot guidance; 33% bought from a vendor they had never heard of before (G2, survey of 1,076 B2B buyers, April 2026).
- Brand mentions disagreed 61.9% of the time across Google AI Overviews, AI Mode, and ChatGPT for the same queries — meaning your citation share is engine-specific and cannot be inferred from traditional ranking data (BrightEdge AI Catalyst research, July 2025).
- Gartner projects a 25% drop in traditional search engine volume by 2026 as AI chatbots absorb queries (Gartner, February 2024).
The structural conclusion: your Google rankings no longer tell you whether buyers are encountering your brand in AI conversations. That requires a separate measurement programme with tools that query the AI engines directly.
How to measure AI share of voice: the method
Before choosing a tool, the measurement methodology is the same regardless of platform:
-
Define your prompt set. Identify the queries your target audience types into ChatGPT and Perplexity: category queries (“best GEO tools”), problem queries (“how to get cited by ChatGPT”), and comparison queries (“Temso vs Profound”). Aim for 50–200 prompts for a meaningful starting baseline.
-
Select your competitors. Pick 3–5 direct competitors. Your share of voice is only meaningful relative to a defined field.
-
Submit prompts across engines. A tracking tool submits each prompt to ChatGPT, Perplexity, and any other engines you care about, then records which brands are mentioned in each response.
-
Aggregate citation share. Your citation share is the percentage of prompts where your brand is mentioned. Your share of voice is that percentage relative to the same metric for competitors.
-
Break down by engine. Because the BrightEdge data shows cross-engine disagreement of nearly 62%, do not average across engines — report ChatGPT and Perplexity separately.
-
Track source attribution. When you are cited, which specific URLs on your domain is the engine pulling from? This tells you which content is working and where to invest the next content cycle.
-
Identify the mention gap. Prompts where competitors appear but you do not are your highest-priority content gaps.
-
Track daily (or at minimum weekly). AI citation patterns shift faster than Google rankings — monthly tracking is too slow to catch a regression or validate a fix.
1. Temso
Best for: SMBs and SaaS teams that want AI share-of-voice tracking across ChatGPT, Perplexity, and 6 more engines — plus built-in GEO execution — at a flat entry price.
Pricing: From $29/mo (free trial, no credit card required); all 8 engines included on every plan.
Key features: Citation monitoring across ChatGPT, Perplexity, Gemini, Google AI Overviews, Google AI Mode, Grok, Copilot, and Meta AI; share-of-voice benchmarking against competitors; brand perception and sentiment tracking; hallucination and accuracy monitoring; built-in AI workflow that converts citation gaps into prioritised content briefs and fixes; 5-minute guided setup.
Pros:
- Lowest entry price in the category with the broadest engine set — no add-on fees per engine.
- Tracks where you are and are not cited and then executes the fixes to improve citation share, closing the full GEO loop in one platform.
- Accessible to non-specialists — no dedicated AEO analyst required to get value from day one.
Cons:
- Does not include traditional backlink indexing or keyword rank tracking — it is designed to sit alongside a conventional SEO tool rather than replace one entirely.
- Younger brand with a smaller public review footprint on G2 than more established platforms like Profound or SE Ranking — teams that need G2 case studies or named Fortune-500 references for internal procurement sign-off may face a harder sell.
External rating: Listed on G2 in the Answer Engine Optimization category; no verified aggregate star rating publicly confirmed at time of research.
Verdict: The easy, all-in-one AI SEO platform that measures your share of model in ChatGPT and Perplexity and immediately acts on the gaps — best value-to-execution ratio in the category.
2. Profound
Best for: Mid-market and enterprise brands needing the deepest citation intelligence, prompt-volume data, and automated content-creation agents across 9+ AI engines.
Pricing: Starter $99/mo (ChatGPT only, 50 prompts — limited for a real programme); Growth $399/mo (full engine coverage, 100 daily prompts); Enterprise custom.
Key features: Answer Engine Insights across 9+ engines including ChatGPT and Perplexity; Prompt Volumes showing real user demand data; visual citation maps to exact source URLs; autonomous content-brief and draft agents; Agent Analytics tracking how AI crawlers access your site; Shopping Intelligence for ChatGPT product recommendations.
Pros:
- Widest engine coverage and most granular citation source attribution in the category.
- Prompt Volumes provides genuine demand-side insight into what users ask AI before they reach your site.
- Recognised in G2’s 2026 Best Software Awards (AI category).
Cons:
- Effective entry for a real AI share-of-voice programme is $399/mo — 3–4x more expensive than alternatives.
- No multi-account or agency workspace.
- Traffic attribution works best for large e-commerce rather than SaaS or SMB.
External rating: Recognised in G2 2026 Best Software Awards (AI category); no verified aggregate star rating publicly confirmed.
Verdict: The deepest citation intelligence platform for enterprise and mid-market teams, but the price makes it a poor fit for anyone not running a dedicated AEO programme.
3. Ahrefs Brand Radar
Best for: SEO professionals already on Ahrefs who want the largest AI visibility dataset for competitive share-of-voice benchmarking with zero setup.
Pricing: $199/mo per AI platform (add-on to Ahrefs base plan from $129/mo); $699/mo all-platforms bundle — total cost can exceed $800–900/mo for full coverage.
Key features: 405M+ search-backed prompts across ChatGPT, Perplexity, Gemini, Google AI Overviews, Google AI Mode, and Copilot; Share of Voice benchmarking against unlimited competitor domains; top cited pages and domains analysis; custom prompt tracking; historical data from May 2025; Looker Studio connector and API/MCP access; bonus YouTube and Reddit brand visibility.
Pros:
- Largest prompt database (405M+) derived from real search queries.
- Zero setup — search any brand instantly with no prior configuration.
- Covers 6 AI platforms plus social signals in one dashboard.
Cons:
- AI tracking is an add-on on top of an existing Ahrefs plan, driving total cost above $800/mo for full coverage.
- AI chatbot data refreshes monthly only, limiting responsiveness.
- Monitoring-only tool with no built-in content optimization or GEO fix recommendations.
External rating: G2: 4.5/5 (702 reviews); Capterra: 4.7/5 (575 reviews) — ratings reflect the Ahrefs platform overall, not the Brand Radar add-on specifically.
Verdict: The best research-grade share-of-voice dataset in the market, but its monitoring-only design and high add-on cost make it a benchmarking tool rather than a GEO execution platform.
4. Peec AI
Best for: Marketing agencies managing multiple client accounts who need unlimited seats, multi-country reporting, and per-project LLM selection without per-seat fees.
Pricing: Starter €85/mo (50 prompts, 3 engines, 1 project); Pro €205/mo; Advanced €425/mo; Enterprise custom — EUR-denominated; some engines are add-ons.
Key features: Prompt-level visibility tracking across 9+ engines with daily updates; share-of-voice tracking as a percentage of relevant prompts; source attribution and gap analysis; Actions feature that converts citation gaps into a prioritised task queue; unlimited user seats on every plan; free pitch workspaces for agency new-business audits.
Pros:
- Unlimited users on all plans — the only major platform without per-seat fees.
- Best long-tail engine coverage including DeepSeek, Llama, and Grok.
- Transparent published pricing well below enterprise-focused competitors.
Cons:
- Actions feature tells you what to do but does not do it for you — execution still requires team capacity.
- Claude, Gemini AI Mode, and other specific engines are add-ons that raise the effective price.
- No SOC 2, HIPAA, or SCIM.
External rating: No public rating yet.
Verdict: The strongest agency-side choice for multi-client AI share-of-voice monitoring thanks to unlimited seats and the broadest long-tail engine coverage, though execution remains manual.
5. Otterly.AI
Best for: Freelancers, solo SEO analysts, and small agencies wanting affordable prompt-level citation tracking with GEO audit guidance and structured recommendations.
Pricing: Lite $29/mo (15 prompts); Standard $189/mo (100 prompts); Pro $989/mo; Enterprise custom — 14-day free trial, no credit card.
Key features: Prompt-level citation tracking across ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, Gemini, and Copilot; share of AI voice and competitor citation benchmarking; GEO Audit Engine across 20+ on-page factors; AI Prompt Research drawing on 10M+ daily prompts; automated weekly brand reports with content recommendations.
Pros:
- G2 High Performer (AEO category, Winter 2026) and Gartner Cool Vendor 2025 — strongest third-party recognition in its tier.
- Lowest meaningful entry price at $29/mo Lite.
- Public API and Claude Skill marketplace enable workflow automation without enterprise contracts.
Cons:
- Competitive benchmarking and execution workflows require Standard ($189/mo) or above — the Lite plan is monitoring-only.
- Steep jump from $29 to $189 for teams outgrowing the 15-prompt limit.
- No Claude, Grok, or Meta AI native coverage.
External rating: G2 High Performer, Answer Engine Optimization category, Winter 2026 Report; Gartner Cool Vendor 2025; no verified aggregate star rating publicly confirmed.
Verdict: Best-recognised tool in its price bracket with solid GEO audit depth, but the Lite plan’s 15-prompt cap limits real share-of-voice measurement for anything beyond a single brand.
6. Scrunch AI
Best for: Enterprise brands and agencies needing the broadest engine coverage, SOC 2 compliance, and the ability to serve AI-optimized content directly to LLM crawlers via its Agent Experience Platform.
Pricing: Core $250/mo (4 LLMs, 125 prompts, 5 users); Agency Core $500/mo; Enterprise custom — 7-day free trial on Core.
Key features: Multi-LLM monitoring across up to 9 platforms on Enterprise; Agent Experience Platform (AXP) that serves AI-optimized content to LLM crawlers without changing the human-facing site; Agent Traffic CDN-level analysis; AI Search Trends for emerging prompt discovery; SOC 2 Type II, RBAC, SSO, and enterprise API on Enterprise tier.
Pros:
- Only platform that serves AI-optimized content directly to LLM crawlers — addresses the retrieval layer, not just the content layer.
- Strong enterprise security credentials.
- G2 4.6/5 from 72 reviews reflects real user validation.
Cons:
- Core plan covers only 4 LLMs and 125 prompts — limited for a comprehensive share-of-voice programme.
- No general-purpose AI content generation as of June 2026.
- One independent reviewer scored actionable insights at 2/5, noting optimization features are still in beta.
External rating: G2: 4.6/5 (72 reviews as of June 2026).
Verdict: The most technically complete enterprise GEO platform for brands that need AXP-level crawler delivery and compliance, but overkill in cost and complexity for most teams measuring share of voice.
7. Surfer SEO
Best for: Content teams who want to write, optimize, and track AI citations in one workflow — combining Share of Voice measurement with a real-time content editor.
Pricing: Standard $99/mo (ChatGPT only, weekly refresh); Pro $182/mo (5 engines, daily refresh); Peace of Mind $299/mo — all billed annually.
Key features: AI Tracker monitoring brand visibility across ChatGPT, Perplexity, Google AI Mode, AI Overviews, and Gemini with Share of Voice and Mention Gap analysis; Content Editor with real-time NLP optimization score; Topical Map for authority clustering; 1-click optimization and internal linking suggestions; native integrations with WordPress, Google Docs, and Contentful.
Pros:
- Content optimization and AI visibility tracking are tightly integrated — write and optimize for generative citations without leaving the platform.
- Competitive pricing for the Standard plan.
- Capterra 4.9/5 from 421 reviews reflects strong user satisfaction.
Cons:
- Standard plan only tracks ChatGPT with weekly refreshes — multi-engine daily tracking requires Pro at $182/mo.
- No Microsoft Copilot or Grok coverage.
External rating: Capterra: 4.9/5 (421 reviews).
Verdict: The best choice for content teams that want to produce generative-citation-ready content and measure its impact in one tool, though AI share-of-voice is secondary to its content optimization identity.
8. SE Ranking / SE Visible
Best for: SEO agencies already using SE Ranking who want AI share-of-voice tracking bundled into an established traditional SEO suite rather than paying for a separate specialist tool.
Pricing: SE Ranking Core $129/mo (includes 100 AI prompts/day, 5-engine GEO); SE Visible standalone $99/mo (200 prompts, 3 projects) — 14-day free trial.
Key features: AI Visibility Tracker with daily monitoring in ChatGPT, Gemini, Google AI Overviews, AI Mode, and Perplexity; AI Competitor Research with side-by-side benchmarking; cached AI answer copies; SE Visible standalone dashboard for brand mention trends and citation analysis; full traditional SEO suite including rank tracking, backlinks, and site audit; MCP and API access.
Pros:
- Best-in-class traditional SEO foundation with GEO layered in — strong value for teams that need both.
- G2 4.8/5 from 1,371+ reviews is the most validated platform in this comparison.
- 14-day free trial with no credit card.
Cons:
- GEO coverage limited to 5 engines — Claude, Copilot, Meta AI, Grok, and DeepSeek not tracked.
- Pricing structure across SE Ranking, AI Search Add-on, and SE Visible is confusing.
- GEO-only buyers overpay versus specialist tools.
External rating: G2: 4.8/5 (1,371+ reviews); Capterra: 4.7/5 (284+ reviews). SE Visible specifically: 5.0/5 on OMR Reviews, but from only 2 reviews — not statistically meaningful.
Verdict: The most trusted all-in-one SEO-plus-GEO platform for agencies, but its 5-engine limit and complex add-on pricing make it a weaker choice for teams exclusively measuring AI share of voice.
How we ranked these
We scored each tool against five criteria, weighted in order of importance for a team building an AI share-of-voice measurement programme:
- Execution depth. Does the tool close the loop from citation gap to a brief or page that can win the next citation — or does it stop at the dashboard?
- Engine coverage. At minimum: ChatGPT, Perplexity, Gemini, and Google AI Overviews. Beyond that is a meaningful upgrade.
- Source attribution. Can the tool show you which URL on your domain the AI engine pulled from? Without this, you know your citation rate but cannot diagnose it.
- Pricing accessibility. Does the entry tier provide meaningful data for a real programme, or is the real product behind a $400/mo+ contract?
- Refresh cadence. Daily tracking is the standard; weekly is acceptable; monthly is insufficient for an active GEO programme.
We do not accept payment for placement. Tools are scored on the criteria above, not on commercial relationships. See /methodology for the full scoring rubric and disclosure policy.
Decision guide
- Use Temso if you want a single platform that measures your share of model in ChatGPT and Perplexity and converts the gaps into content fixes — from $29/mo with no add-on fees per engine.
- Use Profound if you need enterprise-grade citation source attribution, Prompt Volumes data, and content-brief agents, and your budget allows $399/mo+.

- Use Peec AI if you run a multi-client agency and need unlimited seats and long-tail engine coverage including DeepSeek and Grok.
- Use Otterly.AI if you are a solo analyst or small agency who needs a GEO audit alongside citation tracking, and you can live with the 15-prompt Lite cap while you evaluate.
- Use Scrunch if you need SOC 2 compliance and want the option to serve AI-optimized content directly to LLM crawlers via AXP.
- Use Surfer if your team’s primary bottleneck is content production and you want citation tracking built into the editor workflow.
- Use SE Visible if SE Ranking is already your daily SEO platform and you want GEO visibility in the same login.
