DocuXplorer's AI Insights tool

Thinking of building your own AI?

AI has gone from an emerging technology to something businesses are actively looking for ways to use. And with today's AI tools and APIs, it's easier than ever to experiment with building something yourself.

That accessibility can make an internal AI tool or feature seem deceptively simple. Connect a model to your data, build an interface, and you've got a custom AI tool. But not quite.

A production-ready AI application involves much more than connecting to a large language model. You need to think about security, data access, model behavior, accuracy, oversight, costs, maintenance, and potentially regulatory requirements. You also need people who understand the technology well enough to make all of those decisions.

For some organizations, building AI your own AI tool may make perfect sense. But for many businesses that simply want to put AI to work in their existing workflows, building from scratch can be an expensive and unnecessary detour.

That's one reason DocuXplorer has invested in AI document management capabilities. With features like AI Insights and AI Capture, we've already done much of the technical and product development work. Instead of building and maintaining your own AI infrastructure, you can put those capabilities to work in the workflows you already have.

Everyone wants to build AI right now

AI has become a major focus for businesses across virtually every industry. Organizations are looking for ways to automate repetitive work, make information easier to find, process documents faster, and help employees get more done.

And because companies can now access powerful AI models through APIs, the technology can feel incredibly accessible.

A developer can connect an application to an AI model and get an impressive result in a relatively short amount of time. That first demonstration can make it tempting to think, How hard could it be to build our own?

If you want to create a proof of concept that answers a few questions or summarizes a document, it may not be particularly difficult.

If you want to build an AI feature that employees can depend on every day, works with sensitive business information, respects existing permissions, produces useful and reliable results, and can be supported over the long term, you're taking on a much bigger project.

That's an important distinction.

An AI API is not an AI product

A real AI product needs to understand what information it can access, how that information gets to the model, how users interact with it, what happens when the model produces an incorrect answer, and how the organization monitors and improves the system.

You also have to decide which model to use, how much context to provide, how to manage prompts, how to handle documents and other data, and how to keep users from accessing information they're not authorized to see.

And that's before you get to the question of how much all of this will cost to operate. 

Building your own AI is more technical (and costly) than it looks

A company doesn't necessarily need to become an AI research lab to build an AI-powered feature. But it does need expertise that many organizations simply don't have in-house.

Traditional software development knowledge is valuable, but AI introduces a different set of technical considerations. Teams may need to understand how different language models behave, how to manage context and retrieval, how to evaluate AI-generated responses, how to mitigate hallucinations, and how to monitor performance over time.

They also need to make decisions about the frameworks and infrastructure supporting the application.

And because the AI landscape changes so quickly, this isn't knowledge you can acquire once and consider the project finished. Models change. New models become available. Frameworks evolve. Pricing changes. Best practices change. What was considered a good approach six months ago may not be the approach you would choose today.

That creates an ongoing technical commitment.

Even if you have an excellent software development team, that doesn't necessarily mean you have people with experience designing and operating AI systems. Someone needs to understand how to evaluate the quality of AI output, establish appropriate guardrails, monitor the system, and determine when something isn't working as intended.

Then there's the practical question of ownership. Imagine one employee becomes the person who knows how your company's AI system works. They're responsible for maintaining it, monitoring it, making updates, and troubleshooting problems.

What happens when they're out sick, or when they go on vacation? What happens if they leave the company?

You need someone else who understands the system well enough to step in. Suddenly, you're not really talking about one employee maintaining your custom AI tool. You're talking about at least two employees who need enough specialized knowledge to support it.

That's a significant ongoing investment for a capability that may not be central to your business.

And if AI isn't your core product or competitive advantage, it's worth asking whether that's really where you want to put your people and budget.

The true cost of AI isn't just the development

One of the easiest costs to underestimate when building an AI application is the cost of actually running it.

Most AI models charge, directly or indirectly, based on the amount of data processed. That generally means tokens: the pieces of text that models process when they receive a request and generate a response.

The more information you send to the model, and the more frequently your employees use it, the more compute you're consuming.

This matters because an AI application that works beautifully in a small pilot can look very different when hundreds of employees start using it every day.

Imagine an internal document assistant that retrieves several documents for every question, sends that context to a language model, and generates a response. Now multiply that by hundreds or thousands of queries.

Those tokens add up.

Token costs can become an operational problem

It's easy to focus on the price of an AI model in isolation. But you also have to consider how your application uses those tokens.

Are you sending more context than necessary? Are you repeatedly processing the same information? Are your prompts optimized? Are you using an appropriate model for the task? Are you retrieving relevant information efficiently?

Poorly designed AI workflows can consume substantially more compute than necessary. And that's where businesses can bury themselves in costs without realizing it.

At DocuXplorer, we've spent time figuring out how to execute AI requests efficiently because we know that our customers shouldn't have to become experts in token management and compute optimization just to use an AI feature.

Token execution is part of the value we're providing.

You're getting access to an AI capability that we've built into our product and optimized as part of that product.

For a business trying to build its own AI application, those optimization decisions become its responsibility. That means more technical work, more monitoring, and another variable affecting the cost of operating the system.

Key considerations for building an AI tool

Even with the technical expertise and budget, there are other layers to consider: trust, ownership, and compliance.

Trust

Businesses can't treat AI like a black box that produces answers and hope for the best. If an AI system is working with company information, it needs to operate within appropriate boundaries.

That means thinking about core AI trust pillars:

  • Security: How is information protected?
  • Privacy: What happens to the data being processed?
  • Accuracy: How do you evaluate whether the AI is producing useful results?
  • Transparency: Can users understand where information came from and what the system is doing?
  • Oversight: Who is responsible for monitoring and managing the system?
  • Accountability: What happens when the system gets something wrong?

These are practical considerations that are a key part of owning an AI application.

Owning and evaluating the AI

Every AI system will have limitations. Even highly capable models can produce incorrect answers, misunderstand context, or confidently present information that isn't accurate. This is why you must design AI systems thoughtfully.

You need to decide how you will evaluate the system, identify problematic responses, establish guardrails, and determine when a human should be involved.

Additionally, AI isn't like a traditional software feature where you can test it, release it, and assume that the underlying behavior will remain predictable forever. Changes to models, prompts, data, retrieval systems, and user behavior can all affect the experience.

Someone needs to have ownership over the AI. That person must monitor it, evaluate new models, manage permissions, and track the costs.

Regulatory and compliance risks

Building your own AI tool isn’t inherently noncompliant, but when you build and operate the system yourself, you take responsibility for understanding and managing the risks associated with it. Depending on the industry and use case, that can include data privacy, security, access controls, auditability, data retention, transparency, and emerging AI-specific requirements.

And the regulatory environment around AI is still evolving. For organizations in highly regulated industries, that makes governance particularly important.

The more useful an AI tool becomes, the more likely it is to interact with meaningful business information. That might include financial records, customer information, contracts, employee records, invoices, operational documents, or other confidential information.

Once that's the case, organizations need clear answers to questions like: Where does that information go? Who can access it? How is it protected? What happens to it after the AI processes it? Can a user ask the system for information they don't have permission to see?

Those are questions you need to answer whether you're building an AI tool internally or selecting an AI-powered product from a vendor.

The difference is that when you build the system yourself, you're also responsible for building the mechanisms that address those questions.

Before you build, consider what you're actually trying to accomplish

Start with the business problem rather than the technology.

Maybe employees spend too much time searching for documents. Maybe your accounts payable team manually enters information from invoices. Maybe people need a faster way to find answers in large collections of business records.

Those are AI opportunities. But the goal isn't necessarily to create an AI company inside your company. The goal is to solve the problem.

That distinction can make a big difference in how you approach the project.

If AI is a core part of your competitive advantage, if you have a team with deep AI expertise, or if you have a highly specialized use case that existing products can't address, developing your own technology may be worth the investment.

But if AI is simply a means to improve an existing business process, building the underlying technology may not be the best use of your resources.

You need to develop the technology, test it, secure it, manage the data, establish governance, monitor it, optimize its costs, maintain it, and keep your team's expertise current. And you need to keep doing those things after launch.

Alternatively, you can choose a platform that has already made those investments and focus your internal resources on putting the technology to work.

DocuXplorer has already done the work for you

This is exactly why we built AI into DocuXplorer.

We've spent the time and effort to develop AI capabilities around a specific business problem: helping organizations get more value from their documents and the information inside them.

That work has resulted in AI Insights and AI Capture.

These AI features built for document management are designed to support real business workflows.

AI Insights puts your data to work for you

AI Insights gives users a way to interact with information contained in their documents using AI.

Instead of manually opening files, searching through pages, and piecing together information themselves, users can ask questions and get insights from the documents they already have in DocuXplorer.

The important part isn't just the AI-generated response. It's everything that has to happen around it to make that capability useful in a document management environment.

We've done the work of integrating the AI with the platform, building the experience, and thinking through how the technology can be applied to business information.

Your team doesn't need to build that infrastructure themselves.

AI Capture integrates AI into the workflow

AI Capture takes a different approach. Instead of helping users find information after it's been stored, AI Capture uses AI to help process information as documents enter the business.

It can extract information from documents such as invoices, reducing manual data entry and helping information move into the appropriate workflows.

That's an important distinction because useful AI isn't always a chatbot. Sometimes the best application of AI is the part users barely notice: the technology quietly doing work that previously required someone to read, interpret, and manually enter information.

It isn’t just the AI—it's everything around it

When you build your own AI application, you're responsible for the whole stack.

You're responsible for choosing the technology, for figuring out how to use it, and for making it secure. You're responsible for managing access and monitoring performance. You're responsible for optimizing token usage and compute costs. You're responsible for maintaining it when the person who built it leaves.

DocuXplorer has already made those investments.

We've spent time learning what works, what doesn't, and how AI document management can provide practical value.

That means when you use an AI capability in DocuXplorer, you're benefiting from the expertise and development work that has already gone into making it part of the product.

Don't build a tool when you really need an AI-powered workflow

Most organizations aren't looking for an AI tool just for the sake of having it. They want to find information faster, reduce manual data entry, or automate repetitive processes.

They want employees to spend less time digging through documents and more time doing work that actually requires their expertise.

Those are workflow problems, and if an AI-powered capability can solve them, you don't necessarily need to build the AI yourself.

This is particularly important when you consider the total cost of ownership.

The cost of an internal AI tool isn't just the developer who builds it. It's the additional expertise required to maintain it, the ongoing token and compute costs, the infrastructure, the security and governance work, the monitoring, the troubleshooting, and the time your team spends keeping up with a technology that changes constantly.

A purpose-built platform spreads those investments across many customers, making it possible to access capabilities that would be considerably more expensive to develop and maintain independently.

Leverage AI (built by experts) for your use case

The technology has made AI development more accessible, but it hasn't made AI product development simple.

When you build AI yourself, you're taking on more than the initial development project. You're taking on the expertise, infrastructure, token and compute costs, security, governance, oversight, maintenance, and ongoing learning required to keep that AI useful.

For organizations whose business isn't AI development, that may be a lot of investment for something that isn't actually your competitive advantage.

DocuXplorer has already made that investment.

We've developed AI capabilities specifically for document management use cases and continued building the expertise to make AI useful in real business workflows.

So instead of spending your resources figuring out how to build AI, you can spend them figuring out where AI can make the biggest difference in your business.

You don't need to build the AI. You need to put it to work.
