Presentation practice

Rehearse presentations with an AI coach that stays on your computer

Run through your talk out loud and get feedback on how you sound and how you stand: pace, vocal variety, filler words, eye contact, posture and gestures. Free, private and offline.

A rehearsal that tells you what an audience sees

Choose Presentation, record a run-through, and press Next at each slide so Kayavak can time each section. Afterwards you replay yourself as an avatar of your choice and jump straight to the moments worth fixing.

What Kayavak measures

Skill What you see
Pace Words per minute over time, and stretches that drag or rush
Vocal variety Whether your pitch and loudness move, or sit flat
Filler words Every "um" and "you know", highlighted in your transcript
Confident language Hedges like "I think maybe" or "sort of"
Eye contact How much you look at the camera, which stands in for your audience
Posture and gestures Slouching, closed arms, and how open and visible your hands are
Structure How long each section ran

Your best version, side by side

Kayavak's best-version overlay shows the corrected you in full colour over a faint shadow of what you did, with arrows for what should move. Your words get the same treatment: polished, then optionally rewritten by a local AI model and spoken back to you.

Track your progress

Every rehearsal adds to your progress charts, so you can see whether your filler words are dropping and your pace is settling across a week of practice. Export any report as a PDF.

Private by design

Kayavak runs on your Mac, Windows or Linux computer. It keeps movement points instead of video, transcribes speech locally, and never needs an account or an internet connection after the first launch. That's why it can be free forever.
