Get your speaking score in 2 minutes. Record an answer. Impromptu shows what held you back — filler words, pace, clarity, and structure — then gives you a stronger version to try again. You already know what you want to say. The hard part is saying it clearly when someone is waiting. Impromptu is private speaking practice for that moment. You answer out loud, get a score, and see the exact habits that made the answer weaker than it was in your head. Walk in ready for: • Job interviews — a structured answer instead of a ramble • Meetings — a clear update you will not rewrite later • Presentations — calmer pace, fewer fillers • Everyday moments — travel, appointments, plans, and small talk • Impromptu questions — a first sentence that lands Read a real story in the Read tab, then speak about it — summarize it, say why it matters, or take a side. After every attempt you see: • A speaking score, so you know if this take was actually better • Filler words like “um,” “like,” and “you know” • Pace and clarity — rushed, vague, or in control • Answer structure — whether you made a point or circled it • A stronger example of the same answer • Progress over time, so confidence has evidence No class. No audience. No account. Practice on your iPhone until the answer is ready for a real person. Recordings are not stored on our servers. Start with a free two-minute speaking test. Impromptu Pro unlocks unlimited practice, full diagnostics, stronger-answer rewrites, progress history, and real-world packs for interviews, travel, appointments, and everyday conversations.
