InstantSpeech is an AI oral-expression coach that helps you practice eloquence, public speaking, and Mandarin pronunciation. Rambling? Too many filler words? Speaking too fast? Record once, and the AI pinpoints exactly what to improve. Practice before an interview, a presentation, or a speech — and speak with confidence. How it works Record and transcribe: your speech becomes text instantly, ready for review Expression analytics: speech rate, pauses, filler words (um/ah), and vocabulary richness, computed automatically AI Coach: deep analysis of logic and recurring habits, with actionable tips Practice reports: every session is saved, so you can track your progress iCloud sync: your records flow across your devices Who it's for Job interviews: self-introductions, mock Q&A Workplace: reviews, meetings, pitches Public speaking: speeches, impromptu talks, contest prep Mandarin and English practice: pronunciation, reading aloud, tongue twisters Privacy and security Audio recordings are saved on your device and excluded from iCloud backup; when cloud transcription is used, audio chunks are uploaded over HTTPS solely to generate text in real time and are never retained AI analysis sends text only (no audio); nothing is stored on the server, and all traffic is HTTPS-encrypted No ads. No collection of your name, contacts, location, or other personal data Subscription The free version covers recording, transcription, and basic analytics (30 minutes per session, 5 sessions per day, 3 AI coaching sessions per month). InstantSpeech Pro (monthly subscription) unlocks unlimited recording time, 200 AI coaching sessions per month, and all advanced features. The subscription renews monthly automatically, and payment is charged to your Apple ID at confirmation of purchase. Cancel anytime in Settings → Apple ID → Subscriptions — you keep Pro until the end of the current period.
