Your AI coach for speaking under pressure

The Daily 30 challenge and Sharp Duels are completely free, forever. You also get 3 One Shots per week on the free plan. Sharp Pro (£19.99/month or £149.99/year, with a 7-day free trial) unlocks unlimited One Shot, Threaded Challenge, and Industry Insight sessions plus full coaching on the Daily 30.

Sharp Pro is £19.99 per month, or £149.99 per year (a £90 saving — the equivalent of £12.50 per month). Both plans come with a 7-day free trial on your first sign-up. You can cancel any time in Settings > Apple ID > Subscriptions.

Your spoken answer is transcribed by Groq's Whisper model and analysed by Anthropic's Claude across five dimensions: Structure, Concision, Substance, Filler Words, and Awareness. The coaching is grounded in eight communication science frameworks but sounds like a mentor, not a textbook. You also get a model answer you can listen to.

Questions are tailored to your role, company, situation, and any documents you upload (CV, job description, project brief). Preparing for an interview? You'll get interview-style questions. Promotion panel? Leadership scenarios. Sharp also pulls real industry news so your Industry Insight practice stays relevant.

No. Your audio is sent to Groq for transcription and deleted from our servers immediately — never used to train AI models. The recording stays on your device for playback in your session history until you delete your account. All AI providers operate under zero-retention API terms.

ChatGPT reads your text. Sharp listens to your voice. You record yourself speaking under a timer — just like the real thing — and get scored on how you actually sound, not how you type. That's the difference between knowing what to say and being able to say it.

Sharp is purpose-built for high-stakes spoken communication: it listens to your answers, scores you on five dimensions, and coaches with rewrites that quote your own words. Unlike text-based tools (ChatGPT) or presentation-focused tools (Yoodli), Sharp is designed around timed, spoken practice for interviews and pressure conversations.

Sharp counts every filler word in your answer and gives you a target. The trick isn't suppression — it's giving yourself a beat to think instead of filling silence with "um" or "like." Most users cut their filler rate noticeably within two weeks of daily practice.

Yes. Sharp is built for clarity over fluency. Many non-native speakers use it to practise structure and concision in English — the things that matter most in interviews and meetings — without the time and cost of a human coach.

Sharp is built for timed spoken answers under pressure — interviews, pitches, stakeholder updates — and scores on five dimensions with coaching that quotes your exact words and shows the rewrite. Yoodli is more presentation- and meeting-focused. Different problem, different tool.

Sharp's coaching is grounded in eight communication science frameworks including the Minto Pyramid Principle, BLUF (Bottom Line Up Front), the STAR method, the PREP framework, and principles from Made to Stick, Crucial Conversations, Talk Like TED, and Never Split the Difference. The app coaches like a mentor — it never names the books in user-facing copy, but the underlying principles inform every score and insight.

A communication framework by Barbara Minto where you lead with your conclusion, then give your three supporting points, then the evidence under each point. Sharp scores your structure on this principle by default — the most common feedback is "lead with your answer, not the backstory."

Yes. Set your role and context, and Sharp will generate sales discovery, objection-handling, and closing questions tailored to your industry. The Threaded Challenge mode in particular simulates a customer pushing back on your pitch.

Challenge a friend to answer the same question. You both record separately, get scored by the same AI, and compare results side by side. It's always free and it's how you make practice competitive and social.

Recording works offline, but scoring and coaching need an internet connection — your audio goes to our servers for transcription, then to Anthropic Claude for scoring. Once the session is scored it stays in your local history for offline review.

Yes. Settings > Account > Delete account permanently removes your account, sessions, streaks, and uploaded documents from our servers. Two-step confirmation prevents accidental deletion. If you have an active subscription, cancel it separately via Settings > Apple ID > Subscriptions.
