Turn a rough product idea into a PRD draft in seconds
Enter your product name, feature name, overview, feature list, and user feedback, then click Generate My PRD to receive a structured draft written by ChatGPT.
The generator is built on ChatGPT, so the draft follows recognizable PRD structure and is phrased as editable product-manager prose rather than raw bullet fragments.
Add the WriteMyPRD bot to Slack and it will ask what your product does, then help you start the PRD right inside your team's workspace.
A 'Try with a sample requirement' button fills the form with an example so you can see the output quality before investing effort in your own input.
