Ace Practice for a specific moment
Each habit shows up differently depending on what you're preparing for. Ace Coach runs mock sessions for each of these, with an AI on the other side who asks the questions that moment actually brings.
Speaking guides for interviews and calls.
Short, practical guides to the habits that change how you come across: fillers, rambling, pace, confidence, eye contact and your camera setup.
How to stop saying “um”
Measure your baseline, practice the pause and lead with your point.
How to stop rambling
Say the point first, back it up with one or two reasons, then stop.
How to stop talking too fast
Pause at the period, slow down for the line that matters and breathe before you start.
How to sound confident in interviews
Cut the hedges, end statements down and bring a little more energy than feels natural.
How to make eye contact on video calls
Move the call under the lens and look up on the lines that count.
Camera and lighting for video interviews
Camera at eye level, light in front of you and the mic close to your mouth.

An AI interviewer asks the questions your role gets.
