About CleanPrompt
Who we are
CleanPrompt is built by a small product and engineering team across Melbourne and Sydney, led by a user-founder who works with confidential materials every day and needed a safer and more effective way to use AI without exposing sensitive documents.
We believe privacy should not be the price of using AI. CleanPrompt exists to bridge the gap between sensitive documents and productive AI workflows, so people handling confidential material can use AI with greater privacy, context, and control.
