Building a local AI practice tool
A sample product plan for recording answers and reviewing communication.
The product goal
Help someone practice a spoken interview answer, listen back, and make a focused improvement on the next attempt.
A small first version
Start with a prompt, recording controls, playback, and saved practice sessions. Add transcription and a local model only after the basic recording flow works well.
Useful feedback
Keep feedback specific: point to repeated filler words, unclear structure, and opportunities to make an answer shorter. Let the person review the transcript before analysis.
Privacy and control
Explain what stays on the device and what, if anything, is sent elsewhere. Make recordings easy to export or delete, and avoid presenting model feedback as an objective score of a person.
How I would validate it
Test recording reliability, transcription errors, feedback usefulness, and response time on a documented local setup. Use repeated practice attempts to check whether the advice is actionable.
