Why developing proprietary software is now more feasible with artificial intelligence

Paying a monthly subscription for software that offers dozens of features but is only used for three by a company’s team is a common scenario in businesses.

When multiple departments accumulate services of this type, costs rise, and processes often fail to meet the actual needs of the business.

With artificial intelligence tools capable of generating code from natural language instructions, organizations can develop internal applications for specific tasks.

This possibility has reignited a debate in the technology sector: to what extent is it still worthwhile to purchase a ready-made solution when a customized alternative can be built?

Why developing proprietary software has become more accessible

AI-assisted programming tools help create code snippets, build interfaces, identify errors, and speed up testing.

This enables experienced professionals to produce prototypes more quickly, while business teams can participate in defining functionalities without having to write every line of code.

For example, a company that uses a generic system to manage internal requests can create an application tailored to its own workflow.

The software can integrate information, automate steps, and provide only the resources necessary for operation.

When does the cost savings become worthwhile?

The main advantage lies in the potential to reduce subscriptions and adapt tools to the actual needs of the team.

However, the calculation doesn’t end with development. It’s essential to consider infrastructure, security, maintenance, updates, support, and the time of the professionals involved.

An application developed quickly can become expensive if it requires frequent fixes or stops functioning after changes to other systems.

Commercial solutions still offer significant advantages, such as specialized support, regular updates, and features tested in various environments.

For functions critical to the business, these benefits may justify the subscription cost.

The role of AI in creating internal solutions

In May 2026, Anthropic announced an initiative with investors and partners to establish an AI services company targeting medium-sized organizations.

The project aims to develop customized solutions for business operations, reflecting the growing interest in applications tailored to each company.

The decision to build or purchase a tool depends on factors such as complexity, budget, risks, and maintenance capabilities.

How a pre-MBA program in Artificial Intelligence can help

Professionals interested in exploring these possibilities can start by learning about AI tools and practical applications.

Saint Paul’s pre-MBA program in Artificial Intelligence is designed for individuals who already use these resources at a basic level and want to incorporate them more strategically into their careers.

The course consists of four online practical sessions—three recorded and one live—covering approximately 20 tools, including ChatGPT, Claude, NotebookLM, and Manus.

Topics covered include autonomous research, document analysis, and the creation of custom agents.

Upon completion of the training, participants receive a certificate and 30 days of access to Inner AI Pro, a paid platform with over 50 AI tools, valued at R$ 37.
