About WitSpeak
A speaking coach in your pocket, built the way a great tutor teaches
WitSpeak exists because the hardest part of English is the part with the fewest practice opportunities: speaking. Reading, listening, and grammar have endless free material. Speaking has a scarce, expensive resource — a patient listener who corrects you — and WitSpeak turns that resource into software.

Why WitSpeak exists
Millions of learners can pass a grammar test but freeze in a meeting, an interview, or an IELTS exam room. The bottleneck is almost never knowledge — it's spoken practice under light pressure, with someone catching the errors you can't hear yourself make. Human tutors do this brilliantly for a fee per hour; classroom courses ration speaking time to minutes per student; language exchanges are free but nobody corrects you.
WitSpeak's answer: you speak — in roleplay scenarios, everyday conversations, and exam-style sessions with a live AI examiner — and the AI evaluates every answer across fluency, vocabulary, grammar, and pronunciation, then shows you a Band 8-style rewrite of what you just said. Judgment-free, available at midnight, and priced like an app instead of an hourly tutor.

How we build
Pedagogy first, AI second
The AI is the delivery mechanism, not the product. Every practice mode starts from how speaking is actually learned — spoken production, immediate feedback, spaced repetition — and only then asks what the technology can automate.
Feedback you can act on
"Good job, 7/10" teaches nothing. WitSpeak's feedback names the specific filler words, grammar slips, and pronunciation issues in the answer you just gave — then shows you a stronger version of that same answer, so the gap is visible instead of vague.
A judgment-free rep counter
Most learners don't lack ability; they lack safe repetitions. An AI coach that never sighs, never checks its watch, and never laughs is the cheapest way ever built to get the thousands of spoken reps that fluency actually requires.
Honest claims only
Band estimates are calibrated guidance, not official scores — and we say so. WitSpeak is not affiliated with IELTS, the British Council, IDP, or Cambridge. Where our blog compares us to competitors, we link their pages and tell you when they're the better fit.
The company behind the app
WitSpeak is part of the WitPrep family of learning products and is developed by ZenithNexus AI in Miami, Florida. We're a small team by design: the same people who decide how feedback should teach are the ones shipping it to the App Store.
