How Felix works

• Speech-to-text turns your recording into a transcript with timings.
• A large language model reads that transcript plus the measured metrics (pace, fillers, pauses) and writes the coaching, the scores, and the summary.
• If you practiced with the camera on, a small number of still frames are also read by the model so it can comment on posture and expression.

The specific providers are named in the Privacy Policy, which also explains what is and isn't kept.

Both the transcription and the coaching make mistakes. The transcript can mishear you. The feedback can be confidently inaccurate, inconsistent between two attempts at the same thing, or just unhelpful. The scores are a practice aid to measure yourself against over time — not an objective assessment of your ability, and not a prediction of how a real interview, pitch, or audience will go.

Elovox is a practice tool, not a professional service. Nothing Felix says is professional, medical, legal, financial, or career advice. Don't make a decision that matters on the strength of it — use it as one input, alongside people whose judgment you trust.

When you turn the camera on, the model comments on visible delivery — posture, gestures, eye contact, expression. It is reading readily visible behavior to coach you, and it can misread you, especially if you move, present, or express yourself differently from whatever it treats as the norm. It does not identify you, and it builds no face template — see the voice & camera notice. The camera is off unless you turn it on.
