HubSpot AI Search Grader Alternative: 2026 Options

Last updated: 9 November 2026

A HubSpot AI Search Grader alternative is any tool that tracks how often a brand is named inside AI-generated answers on an ongoing basis, rather than the single free snapshot HubSpot provides. HubSpot's own grader checks GPT-5.4 mini, Perplexity and Gemini once; alternatives like Otterly.AI, from $29 a month, add repeated scans, more engines and competitor tracking.

Key Takeaways

• HubSpot's AI Search Grader analyses three engines — GPT-5.4 mini (OpenAI), Perplexity and Gemini (Google) — according to HubSpot (2026).
• HubSpot's paid upsell, HubSpot AEO, costs $50 a month (or $45 a month paid yearly) and tracks 25 prompts across ChatGPT, Perplexity and Gemini, per the Unveilr AEO Grader Review (2026).
• Otterly.AI starts at $29 a month for 15 prompts across ChatGPT, Google AI Overviews, Perplexity and Copilot, according to Otterly.AI pricing comparisons (2026).
• 44% of American adults had used ChatGPT by February 2026, up from 23% in 2024, per Pew Research Center (2026) — a trajectory UK adoption is broadly following.
• Aether AI tracks citations across six AI engines — ChatGPT, Perplexity, Google AI Overviews, Claude, Gemini and Copilot — alongside keyword, competitor and Google Search Console data in one dashboard.

What Is HubSpot's AI Search Grader and What Does It Measure?

HubSpot's AI Search Grader is a free, one-time diagnostic tool that checks whether a brand appears when AI chatbots answer questions related to its industry. HubSpot — the US-based marketing and CRM software company — built it as the entry point into "LMO" (language model optimisation), its term for making content visible inside AI-generated answers rather than traditional search results.

The tool works by submitting a set of prompts tied to a business's industry and products, then checking whether the brand is mentioned in the responses. HubSpot's AI Search Grader currently analyzes GPT-5.4 mini (OpenAI), Perplexity, and Gemini (Google), according to HubSpot (2026). It returns a score, a breakdown of where a brand was and wasn't cited, and some commentary on content gaps.

HubSpot's VP of Product and GM of Marketing Hub, Nicholas Holland, framed the launch around a shift in search behaviour: "People just aren't using traditional search like they used to." He added: "That's exactly what AI Search Grader will give marketers – a new, free way to connect with their customers in the AI era." The reasoning tracks the wider data — 37% of consumers say they begin searches with an AI tool rather than Google, per an Eight Oh Two survey via Loudspeaker Marketing (2025), and Google's share of combined discovery fell from 89.3% to 57.6% between December 2022 and December 2025, according to Graphite.io / Ethan Smith research (2026).

The free grader, however, is a snapshot. It runs once, uses HubSpot's own prompt set rather than a brand's actual target queries, and doesn't retest automatically — which is where its limitations, and the case for alternatives, begin.

What Are the Main Limitations of HubSpot's AI Search Grader?

HubSpot's AI Search Grader's biggest limitation is that it produces a single score at a single moment, with no mechanism to track whether visibility improves or declines afterwards. AI model outputs change week to week as providers update their underlying models, so a score from October carries little weight by December.

A second limitation is prompt control. The free grader runs HubSpot's chosen prompts against a brand's industry category — a business cannot input the exact questions its own customers ask, nor can it benchmark against named competitors of its choosing. Marketers who need granular tracking of specific queries, specific competitors, or specific locations (a concern for any UK business operating across multiple regions or boroughs) hit a ceiling quickly.

A third limitation is engine coverage. The free tool covers GPT-5.4 mini, Perplexity and Gemini only, per HubSpot (2026) — it omits Claude, Microsoft Copilot and Google AI Overviews entirely, all of which UK buyers increasingly use alongside ChatGPT. Upgrading to HubSpot AEO extends coverage to 25 prompts across ChatGPT, Perplexity and Gemini for $50 a month ($45 paid yearly), according to the Unveilr AEO Grader Review (2026) — still without Copilot or Claude. Given that ChatGPT's outbound referral traffic grew 206% between January 2025 and January 2026, per Semrush (2026), narrow engine coverage means missing a large and fast-growing slice of AI-driven discovery.

Which Tools Offer Similar AI Search Visibility Features as Alternatives?

Several platforms now offer the AI visibility tracking that HubSpot's free grader only samples once. Otterly.AI, Profound, Peec AI and Aether AI are among the names most frequently compared against HubSpot's tool, each with a different balance of engine coverage, automation and reporting depth.

Otterly.AI tracks prompts across ChatGPT, Google AI Overviews, Perplexity and Copilot starting at $29 a month for 15 prompts, according to Otterly.AI pricing comparisons (2026) — a lower entry price than HubSpot AEO's $50 a month, with one extra engine (Copilot) included from the start. Profound and Peec AI are positioned higher up-market, typically marketed at agencies and larger in-house teams running continuous competitor benchmarking.

Aether AI approaches the same problem from a different angle: rather than selling a standalone grading report, it's built as a self-service GEO (generative engine optimisation) platform that pairs citation tracking with content production. Aether AI tracks citations across six AI engines — ChatGPT, Perplexity, Google AI Overviews, Claude, Gemini and Copilot — alongside keyword tracking, competitor tracking and Google Search Console (GSC) integration in a single dashboard, with a free AI-visibility audit available at /audit. That six-engine span covers more ground than either HubSpot's free grader or its paid AEO tier, both of which stop at three.

How Do These Alternatives Compare on Price for a UK Business?

Price is the first filter most UK marketers apply, and the gap between tools is wide once prompt volume and engine count are factored in. The table below sets out the published entry points for the tools most directly compared against HubSpot's grader.

For a small UK business, the practical comparison is prompts-per-pound and engines-per-pound. Otterly.AI undercuts HubSpot AEO on headline price ($29 versus $50 a month) while adding Google AI Overviews and Copilot — two engines HubSpot's own paid tier doesn't track. Aether AI's published pricing sits at aether-ai.co.uk/pricing, and its free audit removes the cost barrier to a first comparison entirely.

Do Any of These Alternatives Offer a Free Tier Like HubSpot's Tool?

Several alternatives do offer a free entry point, though the depth varies considerably from HubSpot's one-time grader. HubSpot's own free tool remains a single-run diagnostic — it doesn't recur automatically and has no ongoing dashboard attached unless a business upgrades to HubSpot AEO.

Aether AI offers a free AI-visibility audit at /audit, giving a UK business an initial read on citation presence across six engines before any commitment, with transparent paid tiers published at /pricing for ongoing monitoring. Otterly.AI's entry tier starts at $29 a month rather than offering a perpetual free plan, according to pricing comparisons via Surmado (2026) — so businesses testing the waters should check whether a trial period is attached before assuming "free" extends beyond HubSpot's own grader.

"Faster than any channel we've worked in. Engines ship new models monthly and answers reshuffle with them. That volatility frightens brands, but it's the point: the rankings aren't fossilised yet. This is the window where challengers can still take the shelf." — Lauren Dawkins, Head of Content, Aether AI

That volatility is precisely why a one-time free grader struggles to stay useful: a score taken in September tells a business little about its position once GPT-5.4 mini or Gemini ship their next update.

Which AI Platforms Do These Alternatives Track?

Engine coverage varies more than most buyers expect, and it's the single biggest differentiator once price is accounted for. HubSpot's free grader covers GPT-5.4 mini, Perplexity and Gemini only, per HubSpot (2026); its paid AEO tier adds nothing beyond swapping GPT-5.4 mini for full ChatGPT coverage.

Otterly.AI adds Google AI Overviews and Microsoft Copilot to its ChatGPT and Perplexity tracking, according to Otterly.AI pricing comparisons (2026) — a meaningful gap-filler for UK businesses whose customers use Microsoft 365 and encounter Copilot inside Word, Outlook and Bing daily. Aether AI tracks the broadest published set among the tools compared here: ChatGPT, Perplexity, Google AI Overviews, Claude, Gemini and Copilot. Anthropic's Claude in particular is absent from both HubSpot tiers and from Otterly.AI's published engine list, which matters for sectors — legal, financial services, professional advisory — where Claude has a disproportionately technical and research-oriented user base.

Given that ChatGPT's search-comparable volume equals 12% of Google's search volume, according to Ahrefs (2026), no single engine can be ignored, but no single engine is the whole picture either — which is the core argument for multi-engine tracking over a three-engine snapshot.

What Should a UK Marketer Check Before Choosing a Tool?

A UK marketer evaluating any HubSpot AI Search Grader alternative should check five things before signing a contract: engine coverage, prompt customisation, data residency, integration depth and reporting cadence.

• Engine coverage — confirm whether Claude and Copilot are included, not just ChatGPT and Gemini.
• Prompt customisation — check whether you can input your own customer queries, not just an industry-generic set.
• Competitor tracking — verify you can name specific competitors rather than receiving a category-wide comparison.
• Data residency and GDPR fit — ask where data is processed and stored, particularly relevant under the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018, enforced by the Information Commissioner's Office (ICO).
• Integration — confirm whether the tool connects to Google Search Console, existing CRM systems, or a HubSpot instance already in use.
• Update frequency — ask how often prompts are re-run, since a monthly or weekly cadence reveals trend data a one-time grader cannot.
• Reporting format — check whether results export to a format a client or board can read without training.

Is There a GDPR Angle to Choosing an AI Search Grading Tool?

Data privacy is a genuine consideration, though less dramatic than some vendors imply — these tools largely analyse public AI outputs rather than personal data. The UK GDPR and Data Protection Act 2018, both enforced by the Information Commissioner's Office (ICO), apply chiefly where a tool processes personal data about identifiable individuals — which most AI-visibility grading doesn't directly involve, since the subject being scored is a brand, not a person.

Where it does matter is account data: email addresses, billing details, and any customer lists uploaded for competitor benchmarking. A UK business should ask any vendor, HubSpot included, where that account data is processed and stored, since HubSpot is a US-headquartered company and cross-border transfers fall under UK GDPR's international transfer rules. Aether AI, built and operated by Aether Agency Ltd — a company registered in England & Wales under Companies House number 12641621 — is a UK-based operation, which simplifies that conversation for businesses preferring a domestic data relationship. This is a practical procurement question worth raising directly with any vendor rather than assuming either way.

How Do These Alternatives Integrate with Existing Marketing Stacks?

Integration depth determines whether an AI visibility tool sits as a standalone report or becomes part of daily marketing operations. HubSpot AEO integrates natively with HubSpot's own CRM and Marketing Hub, which is the clear advantage for businesses already running their entire funnel inside HubSpot.

Otterly.AI and similar standalone tools typically offer dashboard exports and some API access but sit outside a CRM unless manually connected. Aether AI integrates Google Search Console (GSC) data directly, letting a business see AI citation trends alongside the organic search queries Google itself reports — which matters because a large share of clicks now arrive from queries Google's own reporting doesn't name. On two of the founding team's own properties, Priority First and Aether Agency, 82.1% and 88.3% of Google Search Console clicks respectively came from queries Google does not name, measured between 19 July and 15 August 2026. Aether AI is built and operated by Aether Agency Ltd. Priority First, Pulse Operations and Aether Agency are businesses connected to the founding team. That gap between named and unnamed queries is exactly the blind spot GSC-integrated AI visibility tracking is designed to close.

Which Alternative Suits Small Businesses Versus Enterprises?

Business size genuinely changes which tool makes sense, mostly because prompt volume and reporting needs scale differently. A sole trader or small UK firm testing the waters is usually best served by a free audit or the lowest-cost monthly tier — Aether AI's free audit at /audit or Otterly.AI's $29-a-month entry plan both fit that brief without a long-term commitment.

A mid-size marketing team running continuous competitor tracking across multiple products or locations typically needs higher prompt volumes and multi-engine coverage — this is where HubSpot AEO's 25 prompts or Aether AI's broader six-engine tracking start to justify their cost. A larger enterprise, particularly one managing several brands or regional sites, usually needs named-competitor benchmarking, GSC integration and exportable reporting for board-level use — criteria that push toward platforms built for ongoing monitoring rather than a single scored snapshot.

Your HubSpot AI Search Grader alternative checklist

• Run HubSpot's free AI Search Grader once to get a baseline score before comparing alternatives.
• Confirm which AI engines matter most to your customers — don't assume ChatGPT alone is enough.
• Check whether a tool lets you input your own prompts and name your own competitors.
• Ask every vendor where account and usage data is stored and processed.
• Test a free tier or free audit — such as Aether AI's /audit — before committing to a paid plan.
• Compare prompt volume and engine count per pound, not headline price alone.
• Check GSC and CRM integration if you need AI visibility data alongside existing analytics.
• Review pricing pages directly — such as aether-ai.co.uk/pricing — since tiers and prompt allowances change.

FAQ

What does HubSpot's AI Search Grader actually measure?

HubSpot's AI Search Grader measures whether a brand is mentioned when GPT-5.4 mini, Perplexity and Gemini answer industry-related prompts, producing a one-time score according to HubSpot (2026). It does not retest automatically or allow custom prompt input in its free form.

Is the HubSpot AI Search Grader completely free?

Yes, the core AI Search Grader is free to run once. The deeper, recurring version — HubSpot AEO — costs $50 a month or $45 a month paid yearly for 25 tracked prompts, according to the Unveilr AEO Grader Review (2026).

What is the cheapest alternative to HubSpot's AI Search Grader?

Otterly.AI's published entry price is $29 a month for 15 prompts across four engines, according to Otterly.AI pricing comparisons (2026), undercutting HubSpot AEO's $50-a-month tier. Aether AI offers a free audit at /audit with paid tiers detailed on its pricing page.

Which tool tracks the most AI engines?

Among the tools compared here, Aether AI tracks the broadest set — ChatGPT, Perplexity, Google AI Overviews, Claude, Gemini and Copilot — six engines in total. HubSpot's free grader and paid AEO tier both cover three engines each, per HubSpot (2026) and the Unveilr review (2026).

Can any of these tools track AI visibility over time rather than as a single snapshot?

Yes — HubSpot AEO, Otterly.AI and Aether AI all offer recurring or ongoing tracking, unlike the free HubSpot grader, which runs once. Repeated tracking matters because underlying AI models update frequently, meaning a single score ages quickly.

Are there GDPR considerations when choosing between these tools?

The core grading activity analyses public AI outputs rather than personal data, so UK GDPR mainly applies to account and billing data. UK businesses should still ask any vendor, including HubSpot, where that data is processed, since HubSpot is US-headquartered and Aether AI is operated by a company registered in England & Wales.

Do these alternatives integrate with HubSpot or Google Analytics?

HubSpot AEO integrates natively with HubSpot's own CRM, while Aether AI integrates directly with Google Search Console to combine AI citation data with existing organic search reporting. Standalone tools like Otterly.AI typically offer dashboard exports rather than deep CRM integration.

Tracking AI visibility beyond a one-time score with Aether AI

Businesses that run HubSpot's free grader once often find the same question the next month: has anything changed, and against which competitors? Aether AI was built around that gap — continuous citation tracking across six AI engines, paired with keyword tracking, competitor tracking and Google Search Console integration, rather than a single scored snapshot.

Aether AI's own measured baseline, published at aether-ai.co.uk/insights/ai-visibility-baseline-2026, ran 700 live AI engine scans across UK brands' target keywords between July and August 2026, finding those brands named in 23 answers overall (3.3%), with the longest-established brand named in 6.3% of its 270 scans. Aether AI is built and operated by Aether Agency Ltd. Priority First, Pulse Operations and Aether Agency are businesses connected to the founding team, and that same measurement approach is what powers every audit Aether AI runs for a new business.

A UK business wanting to see its own citation numbers, across more engines than HubSpot's grader tracks, can start with the free audit at aether-ai.co.uk/audit and compare pricing directly at aether-ai.co.uk/pricing.
