SpeechPolish

SpeechPolish — the only speech app that closes the loop between writing and rehearsal. Most tools stop at the draft. Some grade your delivery. None do both — until now. SpeechPolish writes the speech, scores you recording it, then rewrites the exact weak spots so your next take is measurably better. THE FULL LOOP (industry first) 1. Pick an occasion — Wedding Toast, Eulogy, Business Pitch, Best Man Speech, Award Acceptance, and 3 more. 2. AI writes a structured draft (hook . body . close) in under a minute. 3. Hit Rehearse. Record on-device. Whisper transcribes locally. 4. DNA score on 5 axes: pacing, keyword hit, duration, filler words, pacing variance. 5. Tap any weak axis — AI shows the exact sentences to rewrite, you accept, re-record, and see the delta. WHY IT WORKS . Occasion DNA library: every type ships with proven structure + tone benchmarks (8 occasions in v1.0, 5 more in v1.1). . Teleprompter mode: scroll at your wpm, never lose your place. . Speaker portfolio: your wpm, your best draft length, your strongest occasions — learned from your own recordings. . Marked-up feedback: filler words and pacing dips highlighted on the transcript, tap to jump to that moment. . Draft history: every version of every speech, retrievable forever. PRIVACY BY DESIGN . Mic permission is requested ONLY when you tap Record, and ONLY while you record. . Audio recordings stay on your device. Whisper transcripts stay on your device. . The cloud receives only metadata hashes — never your audio, never your transcript. . No tracking, no ad networks, no IDFA prompt. ATT prompt never shown. . Account delete is one tap and cascades within 30 days (GDPR-grade Edge Function). PRICING . Free tier: 5 AI drafts + 3 recordings per month, full DNA scoring on every recording. . Pro: $4.99 / month or $19.99 / year (save 67%), 7-day free trial. . Pro unlocks: unlimited drafts, unlimited recordings, and the full Rewrite -> Re-record loop. Built by a solo indie developer chasing 20+ honest MVPs in 2026. No VC, no growth hacks. Just careful design for people who care about the words they say at the moments that matter. Subscription auto-renews until canceled. Manage and cancel in App Store account settings. Pricing varies by region. DISCLAIMER AI-generated drafts and rewrites are suggestions. Please read and personalize before delivery — the words you say should be yours.

Verdict
The clearest difference is update cadence: 51CTO at fortnightly against SpeechPolish's every 3 months. 51CTO also leads on iOS requirement (12.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
