The following is a paid product review for ToolJet, an open source, AI-powered, low-code platform for building and deploying custom internal tools and business apps.

In recent years, you've probably come across a few different platforms for building internal tools for you or your team. These tools allow you to build complex apps in minutes using prebuilt components and integrations with popular data sources.

Today I'm excited to share details on another such tool that also includes AI-powered assistance. The platform is called ToolJet.

ToolJet's primary features include:

• Visual App Builder – Create an attractive UI with ToolJet's library of drag-and-drop components and pre-built templates
• Data Sources – Connect with any of ToolJet's 50+ data source integrations, including apps, databases, and APIs
• Workflows – Create complex automations using a visual, node-based interface
• ToolJet Database – A scalable, no-code database management system built on top of PostgreSQL
• Build with AI – Use a natural language prompt to build and refine business apps, which includes help from an AI-powered documentation assistant

Building with AI in ToolJet
The AI-building feature is a great addition to a platform like this, which is already powerful without the AI features. When you sign up for a ToolJet account, you'll see the AI prompt in your workspace, as shown below (I've selected dark mode for my workspace but the default is light mode).

There are a few example prompts you can try out, or just type out your own description. I made my own modification to the "Billing Management System" prompt, and the "Build with AI" sidebar provided me with a thorough breakdown of the full details of the app that will be generated.

This allows me to verify the nuts and bolts of the app. I can make adjustments or, if I like what I see, I can hit "Approve" to generate the app.

The Documentation Assistant
As mentioned, the Build with AI panel includes a Documentation Assistant. You can access this at the top of the panel by clicking the "Learn" tab then typing the question you want to ask.

So if you happen to run into a problem or don't know how something works, just ask the assistant for help.

Components & Templates
Besides the AI features of ToolJet, you'll want to be familiar with the core features that allow you to build and customize your apps. For example, the components are accessible in a right-hand sidebar.

From the sidebar you can search for components by keyword then drag them into your app. Once the components are on the app canvas, you can edit them as needed, just as you would with any GUI component editor.

ToolJet also provides access to a large selection of prebuilt app templates. You can access this feature by clicking the three-dots icon next to the "Create an app" button in your main apps workspace. From there you can "Choose from template", which opens up an overlay to view the currently available templates.

The templates, more than 60 in all, are filterable by category or you can search for a template by keywords.

Connecting to Data Sources
The real power when building apps in ToolJet comes from the ability to connect your app components to data sources. ToolJet allows you to connect to more than 50 different databases, APIs, and similar services.

You can pick from any of those sources, depending on which ones you prefer or have used before.

The ToolJet Database
Alternatively, you have the option to use the ToolJet Database. You can access this feature in the workspace by clicking the "ToolJet Database" icon (2nd from the top) in the left sidebar navigation.

You can create a new database table by clicking the "Create new table" button. This opens a right sidebar panel where you can enter the details of your database.

You can select any of the tables you've created and enter data as needed. You have the option to enter new rows and data manually or do a bulk upload in CSV format (ToolJet provides a template for the required format).

Building Queries to Interact with Your Data
Once your data source is set up, ToolJet allows you to create queries to allow your application to interact with your data. To create a query, select the app you want to create a query for, then click to expand the "Queries" panel, which you'll see in the bottom-left area of the workspace inside the app you're editing.

From there, you can add new queries and edit existing queries using any of the data sources you've connected. The left side of the Queries panel allows you to manage your queries and the right side is a low-code editor where you can construct your queries or simply enter them directly as text (see screenshot above).

More Features
That should give you a pretty good idea what the primary features of ToolJet are all about. There's a lot of power and flexibility, allowing you to build just about any kind of business application.

To wrap up, I won't go into great detail on the following, but just to give you an idea of the comprehensive toolset in ToolJet, here are some other features you'll want to take note of:

• Inspector – View data related to your applications
• Pages –  Create, manage and navigate your multi-page applications
• Marketplace – Enhance your workspaces by adding user-created plugins
• Authentication – Self-hosted and cloud based auth for secure access to your applications and data
• Deployment – Deployment options include Docker, Digital Ocean, AWS, Kubernetes, Azure, and more
• ToolJet API – Interact with the ToolJet platform programmatically to mange users and workspace relations

Feel free to browse ToolJet's excellent documentation for full details on any of the features I've mentioned above.

You can try out all of ToolJet's features today by creating an account. You'll automatically be signed up for a 14-day trial, after which you'll be downgraded to the free version of ToolJet.

ToolJet has a great balance of AI and human features that allow you to build just about anything you want, saving your team time and resources with your own internal apps at a reasonable cost. So try ToolJet today, I'm sure you'll be more than impressed with its comprehensive capabilities.
