Top Singapore GEO Firms: How Their AI Integration Capabilities Compare
Singapore's GEO providers split into two camps. GeoVector sells a self-serve platform that tracks six AI assistants, priced from free to US$1,999 a month. Hashmeta, Horatos.AI, Construct Digital and NEOSEARCH.AI sell services, and Singapore agency retainers commonly run S$3,000 to S$8,000 a month. The question that separates them is simple: is the AI a dashboard you operate, or a programme someone runs for you?
What "AI integration" actually means here
Generative engine optimization (GEO) is the practice of getting your brand named and cited inside AI answers, on assistants like ChatGPT, Gemini and Perplexity. Nearly every Singapore agency now advertises AI capability. That phrase hides two very different products.
The first is client-facing measurement. The firm shows you how AI assistants answer questions in your category, which brands they name, and which sources they cite. GeoVector sits here. The platform tracks six AI assistants: ChatGPT, Gemini, Claude, Perplexity, Google AI Overview and Google AI Mode [1].
The second is internal production. The firm uses AI to research, write and ship its own work faster. Hashmeta describes machine learning that finds content gaps and anticipates algorithm changes, run by more than 50 in-house specialists [6]. That capability lowers the agency's cost of delivery. It says nothing about whether your brand ends up in the answer.
Ask every shortlisted firm which of the two they mean. The answer decides what actually lands in your inbox each month.
Engine coverage: who watches which assistants
Coverage is the first hard number to compare, because a firm cannot report on an assistant it does not query.
GeoVector tracks six: ChatGPT, Gemini, Claude, Perplexity, Google AI Overview and Google AI Mode [1]. One caveat matters for budgeting. The free and Starter plans track two engines. Full six-engine coverage begins on the Growth plan at US$499 a month [2].
NEOSEARCH.AI, a Singapore consultancy, states coverage of ChatGPT, Gemini, Mistral, Claude and Copilot [4]. That list includes Mistral, which most Singapore providers ignore, and leaves out Google AI Overview. If your buyers start in Google rather than in a chat app, check that gap before signing.
Horatos.AI was ranked first in a 2026 Singapore agency roundup, which describes a proprietary engine optimising for Google AI Overviews, ChatGPT, Perplexity and Microsoft Copilot [5]. The firm publishes no engine list of its own, so treat that as third-party reporting rather than a vendor commitment.
Construct Digital takes a different route. Its GEO service targets B2B enterprises across Singapore and Southeast Asia, and frames the work around ChatGPT, Gemini and Perplexity, the assistants its buyers use to build vendor shortlists [3].
Engine lists should not be frozen either. GeoVector's Enterprise plan covers custom requests for engine additions [2]. Naver AI Briefing was the most recent one added, built for brands selling into Korea. Singapore companies with regional revenue hit this constantly, because the assistant your buyer opens depends on their market, not on a vendor roadmap.
Write the engine list into the contract, and ask what it costs to add one. A quarterly review is a bad place to discover that Google AI Mode was never in scope.
Measurement: what shows up in the monthly report
Engine count tells you breadth. Methodology tells you whether the numbers survive scrutiny.
A raw mention count is weak evidence. Being named last in a six-brand answer is not the same result as being the answer. GeoVector applies position-weighted scoring to brand share, so placement inside the response changes the score [1]. It also splits prompts by buyer journey stage, across Discovery, Research and Decision, which is how you tell a top-of-funnel problem from a shortlist problem [1].
Citation reporting is the other half. GeoVector separates cited sources into owned pages, earned sources and outreach opportunities, and scores every cited URL [1]. Sentiment is tracked across the same six assistants, broken out by negative theme such as product quality, service and pricing [1].
Agency-led measurement is usually assembled per client, so ask to see a redacted report before you commit. Construct Digital is direct about the failure mode: teams that never measured citation zero have no lift to report at the next quarterly review [3]. That is the correct test. If a firm cannot show you a baseline in month one, it cannot show you progress in month six.
Three questions cut through most sales decks. What is the prompt set, and who chooses it? Is placement weighted, or is a mention a mention? Can I export the raw citations?
Delivery model: platform, agency, or consultancy
The delivery model shapes cost, speed and how much of the work stays with your team.
A platform is self-serve. You configure prompts, read the dashboard, and act on it with your own people. GeoVector adds a production step to that. A four-step GEO pipeline turns a visibility gap into a draft written for a specific assistant and journey stage, then publishes it to your CMS [1]. Content generation is metered per plan, from 5 articles a month on Starter to 100 on Enterprise [2].
That closes the loop most monitoring tools leave open. It does not close every loop. Nobody writes your strategy for you, every draft still needs an editor, and an unstaffed dashboard is an expense rather than a programme.
An agency retainer inverts that. Hashmeta bundles GEO into integrated digital marketing, holds HubSpot Platinum Solutions Partner status, and runs its own StarNgage platform for influencer work [6]. You get execution capacity. You also get less direct control over the measurement layer.
Construct Digital sells a structured programme aimed at enterprise B2B marketing leaders in Singapore and Southeast Asia [3]. NEOSEARCH.AI positions as a consultancy with D2C and APAC experience, and advertises first results within 30 days [4].
There is a sensible hybrid. Run the platform in-house for measurement and drafting, and retain an agency for volume, editing and outreach. That keeps the baseline under your control while someone else clears the backlog.
What it costs in Singapore
Published prices are scarce in this category, so compare what is actually documented rather than what a proposal implies.
| Firm | Model | Published price | Documented AI capability |
|---|---|---|---|
| GeoVector | Self-serve platform | Free; US$199, US$499, US$1,999 per month [2] | Six AI assistants, position-weighted brand share, citation and sentiment analysis; content generation with CMS publishing [1]; engine additions on request at Enterprise [2] |
| Hashmeta | Agency | S$4,000 to S$12,000+ per month [6] | Machine learning for content gap analysis; 50+ specialists; HubSpot Platinum partner [6] |
| Horatos.AI | Agency | Not published | Proprietary engine covering AI Overviews, ChatGPT, Perplexity, Copilot, per third-party roundup [5] |
| Construct Digital | Agency | Not published | Structured GEO programme for B2B enterprises in Singapore and Southeast Asia [3] |
| NEOSEARCH.AI | Consultancy | Not published | GEO across ChatGPT, Gemini, Mistral, Claude and Copilot; first results in 30 days [4] |
For context on the service side, Singapore SEO retainers run from about SGD 1,500 to SGD 15,000 and above [7]. Most businesses pay SGD 3,000 to SGD 8,000 a month for comprehensive work [7]. GEO usually sits inside that same retainer rather than beside it.
The gap is wide. Six-engine platform monitoring at US$499 a month costs roughly a tenth of a mid-range Singapore retainer. Those are not competing purchases. One buys visibility into what AI says about you. The other buys the hands to change it.
Two budget notes for Singapore teams. Platform pricing here is quoted in USD, so build in the exchange rate when you compare against an SGD retainer. And check the credit model: GeoVector meters prompts as credits, with 200 on Starter and 500 on Growth, refreshed weekly [2]. A 40-prompt tracking set behaves very differently from a 400-prompt one.
How to choose
Match the model to what your team is missing.
Choose a platform if you have marketers who can act on data but no visibility into AI answers. Start on the free tier, track 15 prompts across ChatGPT and Gemini, and confirm the problem is real before spending [2]. Move to Growth when you need all six engines and competitor tracking [2].
Choose an agency if the constraint is capacity. Hashmeta suits mid-market and enterprise teams running multi-channel campaigns [6]. Construct Digital fits enterprise B2B firms selling across Southeast Asia [3]. NEOSEARCH.AI fits D2C brands that want speed and a focused consulting engagement [4].
Whichever way you go, insist on three things in writing: the engine list, the prompt set, and a baseline measured before work begins. Firms that resist any of the three are selling activity, not outcomes.
Run the free audit first. Get your baseline, then decide who you pay to move it.
Frequently asked questions
Which Singapore firms track brand mentions in ChatGPT and Perplexity?
How do I evaluate a GEO firm's measurement methodology?
Test three things. Ask whether brand share is position-weighted, since a first mention and a last mention are different outcomes; GeoVector weights by position [1]. Ask whether prompts are segmented by buyer journey stage [1]. Ask for a baseline before work starts, because you cannot report a lift you never measured from zero [3].
What should a monthly AI visibility report contain?
At minimum: brand share per engine with position weighting, prompt-level results split by journey stage, and every cited URL sorted into owned and earned sources [1]. Sentiment by theme is useful when AI answers repeat a specific criticism [1]. Anything less makes it hard to decide what to publish next.
What does GEO cost for a Singapore company?
Platform monitoring starts free, with paid tiers at US$199, US$499 and US$1,999 a month [2]. Agency work costs more: Hashmeta publishes S$4,000 to S$12,000 and above per month [6], and Singapore retainers overall cluster between SGD 3,000 and SGD 8,000 [7]. Most other GEO providers here quote on request.
Do I need an agency if I already have a GEO platform?
Only if production capacity is the bottleneck, and check what your platform already covers. GeoVector turns visibility gaps into drafts and publishes them to your CMS, with 5 to 100 articles a month depending on plan [1] [2]. Someone on your side still edits, approves and promotes that work. Teams with one in-house writer often start solo and add an agency when the backlog outgrows them.
