Data cleaning (Dex, Data Processing Specialist)

AI employees extract structured information from unstructured content such as customer data, tickets, or contract text and can automatically populate forms.

Data analysis (Viz, Insight Analyst)

On pages like Leads, Opportunities, or Accounts, AI employees can analyze the current dataset and automatically create trend charts, comparisons, KPI cards, and concise insights.

Frontend configuration (Nathan, Frontend Engineer)

When working with JSBlock, JSField, JSItem, JSColumn, JSAction, or Event Flow, AI employees can review the code context and generate or refine JavaScript based on natural language prompts.

Data modeling (Orin, Data Modeler)

When creating internal systems such as CRMs, ticketing, inventory, or project management, AI employees can help generate or update data tables.

NO.4 Budibase

Overview

Budibase is an open source low code platform for building internal tools. It supports database connections, multiple data sources, drag and drop UI creation, and automatic CRUD and workflow generation, making it suitable for building enterprise backends, approval flows, form systems, and admin panels. With its built in database, REST API support, and visual builder, teams without extensive frontend experience can still create complete internal applications.

Budibase has also integrated AI as a native platform capability. With Budibase AI enabled, users can create AI Columns for intelligent data operations, generate JavaScript logic from natural language, automatically produce database schemas, and use AI based automations for cleaning, classifying, transforming, and generating data.

Use cases

Smart data cleaning and content preparation

AI Columns can automatically clean, normalize, and categorize data, useful for customer feedback, content moderation, ticket processing, and similar workflows.

Auto generating database schemas

When building new modules such as customer management, contract workflows, or task systems, Budibase AI can generate suitable table structures and example records from a single natural language prompt.

NO.3 Refine

Overview

Refine is an open source React meta framework built for CRUD heavy web apps, enterprise admin systems, dashboards, and other internal B2B tools.

Refine AI brings AI into the development workflow. With natural language, documentation, or API specs as input, Refine AI can generate a complete production ready React app scaffold, including CRUD pages, routing, auth, state management, and data fetching. The output is clean, standard React code that developers can extend or adapt freely.

Use cases

Generating admin systems

Based on APIs or data models, Refine AI can create CRUD interfaces with list, form, and detail pages, making it ideal for quickly bootstrapping systems such as inventory, orders, or project management.

Refactoring and maintaining existing codebases

Because Refine AI generates code that follows enterprise grade patterns and best practices, it can also be used to refactor older systems into modular components or to add new business modules quickly on top of an existing project, improving both development speed and long term maintainability.
