This is one of the biggest challenges with adding AI to SaaS products. Customization can make the product much more useful for specific customers but every extra prompt, workflow, integration, or piece of business logic creates something the team has to maintain later. I’d probably focus on building flexible systems rather than heavily customized ones and only add complexity when it clearly enhances the user experience or solves an important problem. Over time, simplifying the AI stack might actually create more value than constantly adding new layers.
