Diffwise.app tools create practical outputs that you can keep, review, and share. They do not hide the result behind an account.
The project brief builder records the audience, product goal, current state, constraints, timeline, and connected delivery questions. The tool keeps entered project details in your browser.
Use the output to compare a product agency, specialist freelancers, or an in-house team. The brief does not estimate price or promise a delivery date. It gives every provider the same starting information.
Review the generated brief before sharing it. Remove confidential details and add the acceptance evidence that matters to your product.
