What it is

Use ToolJet to create custom business apps and workflows.

Real use case example

"A founder wants to automate a weekly report. She uses ToolJet to connect a Google Sheet to a Notion database and a Slack channel. Every Monday morning, she gets a detailed report directly in her Slack without lifting a finger."
