Reviewers consistently say Tough Tongue AI is easy to use, realistic, and genuinely useful for practicing interviews, sales pitches, presentations, and other difficult conversations. Many highlight the wide range of scenarios, human-like voice interaction, clean UI, and feedback that pushes them to improve rather than simply accept answers. Several also describe practical team and hiring use cases, from manager training to applicant screening. The main caveat is that the newer coding interview experience still seems early, with some users noting crashes, delayed transcripts, and missing features in the editor.
