Build vs buy: should you build your own AI visibility tool?

Developer APIs don't capture what users actually see in AI search results, making DIY monitoring tools misleading and far more complex to build than most teams realize.

Updated ·Reviewed by Kai Forsyth·8 min read

For most engineering teams, an AI visibility monitoring tool seems straightforward. Query the OpenAI and Anthropic APIs, parse responses for brand mentions, store the data. With AI coding assistants, this looks like a weekend project.

The reality: what starts as simple data collection becomes permanent infrastructure that taxes your roadmap indefinitely. And worse, the data you collect isn’t actually measuring what matters.

Why AI visibility monitoring matters

AI search is changing how customers discover brands. When people use ChatGPT, Perplexity, or Google AI Overviews to research products or services, the AI’s recommendations directly shape which brands get considered. Strong visibility in these responses drives traffic and conversions. Invisibility means losing market share to competitors who do appear.

Effective monitoring requires accurate data reflecting real user experiences, consistent tracking across multiple platforms, sophisticated analysis that produces strategic insights, and continuous adaptation as platforms evolve weekly.

The API trap: measuring the wrong thing

Here’s what most teams miss: ChatGPT and the OpenAI developer API are fundamentally different products. Yes, they use the same underlying language models. But the consumer product that actual users interact with is a completely different experience built on top of those models.

ChatGPT has shopping integrations that surface product cards with images, prices, and direct purchase links. It has web browsing that pulls real-time information and formats citations specifically. It has visual hierarchies, interactive elements, and presentation logic that determines what users actually see and click. None of this exists in the developer API.

The same is true everywhere. Perplexity’s consumer interface presents differently than its API. Google AI Overviews in search results show different formatting than what is produced by their Gemini models. Every consumer platform has teams building experiences on top of base models specifically for end users.

When you build monitoring using developer APIs, you’re measuring brand salience in the underlying language model. But users interact with the consumer product, not the model. Your brand and a competitor might both get mentioned in API responses, suggesting equal visibility. But in the actual consumer product, their brand appears in a prominent shopping card with imagery while yours is in paragraph text below the fold. Your data says “equal visibility” but traffic, clicks, and conversions tell a completely different story.

You’re optimizing for a metric that doesn’t correlate with business outcomes. This isn’t a minor data quality issue: it’s measuring the wrong thing entirely.

What accurate monitoring actually requires

Capturing what users see means interacting with consumer products directly, not APIs. This requires sophisticated infrastructure to handle the complexity of modern web applications: dynamic rendering, asynchronous content loading, and capturing full visual presentation across different devices and formats.

Each platform requires a completely different technical approach. ChatGPT, Perplexity, Gemini, Claude, and Copilot are all built differently, update independently, and present information in unique ways. Building and maintaining collection infrastructure for even one platform is substantial work. Doing it reliably across five or more platforms is a full-time engineering commitment.

But data collection is only the beginning. The real complexity emerges when you need to make sense of unstructured, qualitative AI responses. You need models that can accurately detect brand mentions across varied phrasing and contexts, analyze sentiment and positioning in nuanced language, identify topics and themes across thousands of responses, and distinguish between direct mentions, implied references, and competitive comparisons. This NLP and machine learning work represents a substantial engineering investment that most teams dramatically underestimate.

Then there’s normalization. Each platform returns data in different formats with different structures. You need to transform disparate data sources into a consistent, actionable view that allows meaningful comparisons and trend analysis across platforms. This data engineering work is tedious, ongoing, and essential for useful insights.

Each platform ships updates weekly or more frequently. Each update can break your data collection. Your team needs to respond quickly to avoid data gaps that make trend analysis impossible. AI platforms are also rapidly adding new features – shopping capabilities, enhanced citations, new content formats – each requiring updates to your monitoring infrastructure to capture accurately.

What looks like a one-month project becomes a permanent team expense. Most teams building their own tools underestimate this by an order of magnitude.

What Hall delivers

Hall has already built this infrastructure. We’ve invested in the complex data collection systems, hired specialized engineering teams, and created operational processes to maintain reliability across all major platforms. When ChatGPT ships an update, our engineers ensure continuity. When a new AI platform reaches scale, we add coverage proactively.

But the platform advantage goes beyond avoiding infrastructure work:

Deep citation intelligence: Hall tracks which sources drive AI mentions of your brand, but goes further by analyzing the actual content being cited. We examine the cited pages to understand what specific information, messaging, and content formats AI systems prefer. This reveals why certain content earns citations while similar content doesn’t, informing your content strategy with concrete insights about what works.

Sophisticated parsing and analysis: Our models accurately detect brand mentions across varied contexts, analyze sentiment and competitive positioning, identify emerging themes and topics in how AI systems discuss your category, and track changes in narrative over time. This qualitative analysis turns raw responses into strategic intelligence.

Competitive benchmarking: We monitor your competitors alongside your brand, providing share of voice analysis, positioning comparison, and trend tracking. You see exactly where you stand in your category and identify opportunities competitors haven’t captured.

Unified multi-platform view: Hall normalizes data across ChatGPT, Perplexity, Gemini, Claude, and Microsoft Copilot into one consistent framework. You get comparable metrics, unified dashboards, and the ability to understand which platforms drive the most valuable traffic and where to focus optimization efforts.

Automated monitoring and alerts: The platform continuously tracks your visibility and alerts you to significant changes. When a competitor suddenly gains share of voice, when new topics emerge in your category, or when citation patterns shift, you know immediately rather than discovering it weeks later in a manual review.

Content recommendations: We identify content gaps and optimization opportunities based on what’s actually earning citations and visibility across all platforms. Not generic SEO advice, but specific guidance grounded in patterns we see working repeatedly.

Attribution and traffic insights: Integration analytics lets you track how AI visibility translates to website traffic, conversions, and revenue. You can prove ROI from AI optimization efforts.

Global insights: For brands operating internationally, Hall monitors how AI engines represent you across different geographies and languages, identifying regional opportunities and inconsistencies.

Continuous product evolution: We’re constantly shipping new capabilities, analysis methods, and platform coverage. You benefit from ongoing product development without dedicating your own resources. Our roadmap is driven by needs across hundreds of customers, ensuring we build what actually matters.

Cross-customer intelligence: We see patterns across hundreds of brands and millions of queries. This aggregate insight helps us identify what content strategies work, which optimization tactics drive results, and how different industries should approach AI visibility. You benefit from learnings across our entire customer base.

Making the decision

Even if you’re an agency or platform company where this capability seems adjacent to your business, the opportunity cost is high. Your engineering talent and strategic focus are better spent on what uniquely differentiates you in the market. Building monitoring infrastructure diverts resources from your core value proposition.

Build only if you have dedicated engineering resources committed full-time and accept 12+ month timelines before production readiness - and even then, question whether that investment creates competitive advantage.

Buy if you need accurate insights to drive marketing strategy, want comprehensive multi-platform coverage, value speed measured in weeks not months, or monitoring is a supporting capability rather than your core business.

Most teams fall into this second category. They need AI visibility data to inform strategy, but building the monitoring infrastructure doesn’t create competitive advantage.

Where to focus your energy

The question isn’t whether you can technically build a monitoring tool. Most competent teams could build something with enough time. The question is whether building monitoring infrastructure is the best use of your team’s limited attention and resources.

The competitive advantage in AI visibility comes from creating authoritative content, earning quality citations, building domain expertise, and optimizing faster than competitors. These are strategic capabilities that differentiate your brand. Monitoring infrastructure enables strategy but doesn’t create it.

Your team should be focused on acting on insights, not building measurement systems. The work that matters is creating better content, building relationships that earn citations, and optimizing based on what you learn. That’s where competitive advantage lives.

Buy the monitoring capability. Focus your engineering talent on building your actual product. Focus your marketing team on the strategic optimization work that drives results. The AI landscape is moving quickly - brands establishing strong monitoring and optimization practices now are building advantages that compound as AI-driven discovery becomes the primary customer journey.

Your team’s energy is finite. Spend it where it creates lasting competitive advantage, not on rebuilding infrastructure that already exists.
