Review DontBuildThis?

DontBuildThis is praised for its ability to provide quick, domain-specific feedback on startup ideas, helping users decide whether to proceed or pivot. Users appreciate its combination of usefulness and playfulness, with many finding the brutally honest feedback both refreshing and accurate. The tool is seen as a valuable resource for fine-tuning business ideas and is recommended for anyone looking to validate their concepts before investing significant time and resources. However, some users express concerns about data retention and limited free usage.

Got roasted, but also very helpful. I thought it was going to be a gimmick tool, but the results were actually really helpful, brutal but true, and helpful to fine tune some of my business ideas.
