I came across CoachFrame, an AI tool focused on structured interview prep. Unlike general chat-based mock interviews, it emphasizes scoring your performance across dimensions like clarity, structure, and confidence, then diagnoses weaknesses and assigns specific drills to improve them. You re-test to track measurable progress. It's voice-first for low-latency conversations, supports roles like software engineering, PM, sales, and behavioral interviews. Free tier gives 1 scored session/month, Pro is $29/mo for more sessions and full dashboard. The approach of "interview → diagnose → drill → re-test" with actual metrics seems useful for deliberate practice. Curious what HN thinks—has anyone tried it or similar tools that go beyond just chatting?
