Presence Public Speaking Coach

You can't hear yourself the way an audience does, and confidence comes from knowing, not guessing. Presence records a practice run and scores how you actually came across, 21 dimensions in all, all analyzed on your device. PRACTICE YOUR WAY No material yet? Browse a library of ready-made scripts and curated question sets, from job interviews and sales pitches to wedding toasts, difficult conversations, and small talk. Read a script verbatim and watch Presence track your words live, one at a time, as you say them. Work through a set of questions, ticking each off as you answer. Or write your own, import one from Files, iCloud Drive, Word, or PDF, or build one from a past recording's transcript. Before you record a single word, Presence reads it back to you: roughly how long it will take to say out loud, how many big ideas you are actually carrying, and whether your opening earns attention. Catch the rambling before you record it, not after. Already have a recording? Import an audio or video file directly and Presence scores it exactly the same way, no need to record it again. ONE SCORE, FOUR THINGS TO WORK ON Your delivery score breaks into four groups, each explained in plain language instead of a bare number: • TIMING: pace and pauses. • VOICE: volume consistency, emphasis, opening energy, intonation and vocal range (exactly where you flattened into a monotone), and confidence, whether you land your sentences or trail off at the end. • WORDS: fillers, hedging, absolute language, sentence length, word variety, and tone. • BODY LANGUAGE: gestures, posture, fidgeting, eye contact, stability, expressiveness, and blink rate, when you turn on practice video. SEE YOUR EYE CONTACT, NOT JUST HEAR YOUR VOICE Turn on practice video, always optional, and Presence scores how you come across on camera as well as how you sound, using real on-device computer vision. Nothing else in this category goes this deep on body language. Leave it off and everything else still works exactly the same. WATCH IT ACTUALLY WORK Every recording feeds your trend. Your streak, your total practice time, the dimensions you have improved most since you started, and the ones still worth your attention. Progress you can point at, not just hope for. LEARN WHAT GOOD LOOKS LIKE A 220+ item library of frameworks, principles, techniques, and exercises drawn from real, named sources, like PREP: Point, Reason, Example, Point. Searchable, favoritable, and recommended to you based on what your last recording actually needs. SHARE YOUR REPORT CARD Proud of a take? Want a coach, a mentor, or a friend to look at it? Share your score and the highlights in a tap. HANDS-FREE WITH SIRI AND SHORTCUTS Start a take without touching the app: ask Siri to start a recording in Presence. Ask for your latest score or a progress summary and hear it spoken, or find any recording by name in Spotlight. YOUR RECORDINGS STAY ON YOUR DEVICE Transcription, every scored dimension, the video analysis, and the coaching summaries all run on your device. No account, no ads, no tracking, and your voice and video are never uploaded. Whether it is a keynote, a job interview, a Toastmasters speech, a wedding toast, or just saying "um" a little less, Presence shows you what to work on and why.
