Build Internal Tools with AI - No Engineers Required
Your team deserves tools built exactly for how they work. Greta builds custom internal software from a plain description - in hours, not the months it takes to hire a dev team.
Internal tools are custom software applications built specifically for use inside a business - not for customers, but for your own team. Examples include approval workflows, inventory trackers, employee dashboards, onboarding checklists, and order management systems. Historically, building internal tools required hiring engineers and waiting months. With Greta's AI app builder, any business can create professional internal tools from a plain text description with no coding. You describe the tool your team needs and Greta builds the complete, working application. Internal tools built with AI deploy in hours, cost a fraction of custom development, and can be updated anytime by describing the change.
