Last updated June 2026. Added documented accuracy gap data for Brand Radar on ChatGPT and Perplexity; confirmed Ahrefs all-in pricing tiers.
TL;DR
The category distinction here is monitoring-only versus monitor-plus-execute. Ahrefs Brand Radar is a large-scale AI visibility research database bolted onto an SEO suite — genuinely useful for Google AI Overviews benchmarking if you already have an Ahrefs subscription, but silent on Claude, Grok, and Meta AI, and silent on what to do about any gap it finds. Temso is a purpose-built AI visibility platform that covers all eight major engines, surfaces share of voice and sentiment daily, and ships the execution workflow — content, citations, brand perception — from inside the same dashboard, starting at $29/mo.
For most SMBs, SaaS teams, and growing brands, Temso is the obvious call. The case for Ahrefs Brand Radar is narrow: enterprise teams with existing Ahrefs contracts, in-house data analysts, and a primary focus on Google AI Overviews competitive benchmarking.

Why AI visibility tracking matters now
The macro context shifted quickly:
- 51% of B2B software buyers now begin purchase research in an AI chatbot, up from 29% one year earlier — G2 “The Answer Economy” AI Search Insight Report, April 2026.
- 69% of B2B software buyers chose a different vendor than initially planned based on AI chatbot guidance; 33% bought from a vendor they had never heard of before that interaction — same G2 survey of 1,076 B2B buyers.
- Brand mentions in AI responses disagreed 61.9% of the time across Google AI Overviews, AI Mode, and ChatGPT; only 33.5% of queries produced the same brand names across all three engines — BrightEdge AI Catalyst research, July 2025.
- ChatGPT weekly active users grew from 400M in February 2025 to 900M by February 2026 — OpenAI via TechCrunch.
- Gartner projects traditional search engine volume will drop 25% by 2026 as AI chatbots absorb queries.
The implication for this comparison: if your buyers are doing purchase research across eight AI engines and your tracking covers only six of them — or worse, reports 97% fewer mentions than actually exist on the ones it does cover — you are flying partially blind. That is the practical gap between these two tools.
1. Temso
Best for: SMBs, SaaS teams, and growing brands that want AI visibility monitoring and AEO execution in one flat-price subscription — without needing a separate optimization tool or specialist headcount.
Pricing: From $29/mo with a free trial, no credit card required. All 8 AI engines are included on every plan. No per-engine add-on fees.
Key features:
- AI visibility tracking across 8 engines: ChatGPT, Perplexity, Gemini, Google AI Overviews, Google AI Mode, Grok, Microsoft Copilot, and Meta AI
- Share of voice and share of model benchmarking versus custom competitor sets
- Brand mention and citation monitoring with source-level attribution
- Sentiment and brand perception tracking
- Hallucination and accuracy monitoring — flags cases where the model describes your product incorrectly
- Built-in AI workflow that prioritizes gaps and executes fixes across content, citations, and brand perception
- Guided 5-minute setup, no specialist configuration required
Pros:
- Broadest engine coverage in this comparison — 8 engines on every plan including Grok, Meta AI, and Claude, with no add-ons
- Only tool in this pairing that closes the loop: identifies the gap and ships the fix from the same dashboard
- Accessible entry price ($29/mo) and setup designed for marketing generalists, not data analysts
Cons:
- Does not include traditional SEO capabilities such as backlink indexing, keyword rank tracking, or site audit — teams that also need conventional SEO data will need a dedicated SEO tool alongside it
- Newer platform with a smaller public review footprint on G2 compared to Ahrefs, which has thousands of verified reviews built up over more than a decade — buyers running a formal vendor review process should account for that difference in social proof
External rating: Listed on G2 in the Answer Engine Optimization category. No verified aggregate star rating publicly confirmed at time of writing.
Verdict: The easy, all-in-one AI SEO platform for teams that want to monitor share of voice, brand mentions, and prompt visibility across 8 engines — and then fix the gaps — without paying enterprise prices or hiring a specialist.
2. Ahrefs Brand Radar
Best for: Enterprise brands and SEO agencies already on a paid Ahrefs plan that need a large-scale AI visibility research database for competitive benchmarking, especially across Google AI Overviews and AI Mode — and have an in-house data team to act on the findings.
Pricing: $199/mo per single AI platform index, or $699/mo for the all-platforms bundle (includes 2,500 custom prompt checks). Both are add-ons requiring a paid Ahrefs base plan: Lite from $129/mo, Standard $249/mo, Advanced $449/mo. Minimum all-in cost for full AI coverage: $828/mo. Custom prompt tracking is available separately: Basic $50/mo (2,500 checks), Growth $100/mo (7,000 checks), Scale $250/mo (25,000 checks).
Key features:
- 405M+ search-backed prompts across 6 AI platforms: Google AI Overviews, Google AI Mode, ChatGPT, Perplexity, Gemini, and Microsoft Copilot
- Share of voice benchmarking against unlimited competitor domains with no project setup required
- Cited pages and domains analysis to identify citation opportunities
- Custom prompt tracking for monitoring specific high-value queries
- Historical AI visibility data: Google AI Overviews from August 2024; AI chatbots from May 2025
- Looker Studio connector, API/MCP access, and Report Builder
- YouTube and Reddit brand mention tracking (beta)
- Web visibility data drawing on 16.9B indexed pages
Pros:
- Largest prompt database in the category (405M+), derived from real user search queries rather than synthetic prompts — particularly strong signal for Google AI Overviews
- Zero-friction brand lookup: search any brand, product, or person instantly without configuring a project
- Unique cross-surface visibility: connects AI citation data to branded search volume, web mentions, and YouTube presence in a single dashboard
Cons:
- Expensive for what it is: full AI visibility coverage costs $828–$1,148/mo all-in, roughly 2.5x the industry average for dedicated AI visibility tools — and that budget only covers monitoring, with no execution layer
- Documented accuracy issues on ChatGPT and Perplexity: independent testing found Brand Radar reported 3 mentions where 123 actually existed (97.5% underreporting) and a 97.2% gap on Perplexity, attributed to snapshot-based methodology that misses responses generated between scheduled captures
- No coverage of Claude, Grok, or Meta AI — three platforms with significant and growing combined user bases
- No sentiment analysis, no hallucination monitoring, no content optimization, no AEO fix recommendations — monitoring only
External rating: G2: 4.5/5 (702 reviews); Capterra: 4.7/5 (575 reviews). Note: these ratings reflect the Ahrefs platform overall, not Brand Radar specifically, which launched as a distinct product in 2025.
Verdict: The most comprehensive AI visibility research database for enterprise teams already on Ahrefs, but its $828+/mo all-in cost, documented accuracy gaps on ChatGPT and Perplexity, absence of Claude/Grok/Meta AI, and monitoring-only model make it a poor fit for teams that need affordable, complete, and actionable share-of-voice tracking.
How we ranked these
This comparison ranks tools against four criteria:
- Engine coverage. How many of the eight major AI engines does the tool track, and does it treat them equally or charge per engine?
- Data accuracy and methodology. Is monitoring continuous or snapshot-based? Are accuracy gaps documented and disclosed?
- Action vs. monitoring. Does the tool stop at the dashboard, or does it help close the gap with optimization guidance and execution?
- Pricing accessibility. Can a team with a realistic marketing budget get meaningful coverage, or is the real product behind an enterprise contract?
Temso ranks first because it scores well across all four dimensions. Ahrefs Brand Radar scores well on coverage depth for Google AI Overviews specifically, but its pricing, engine gaps, accuracy issues on two of the six platforms it covers, and absence of any execution layer pull it to second. Full scoring methodology and editorial independence policy are documented at /methodology.
Decision guide
Use Temso if you need daily monitoring across all eight major AI engines, want to track share of voice and sentiment against competitors, and need the execution workflow — content optimization, citation building, brand perception fixes — without hiring a specialist or buying a second tool. Starts at $29/mo.
Use Ahrefs Brand Radar if you are already on a paid Ahrefs plan, your primary AI visibility priority is Google AI Overviews competitive benchmarking, you have an internal data analyst team, and you do not need to track Claude, Grok, or Meta AI. Budget $828+/mo all-in.
Use neither as your only tool if you need both traditional SEO capabilities and full AI visibility coverage. Temso handles the AI layer; pair it with any conventional SEO platform for backlinks, keyword rank tracking, and site audit workflows.
