Orator turns your phone into a personal speech coach. Pick a topic, speak, and get scored in seconds — with every filler word, hedge, and weak phrase highlighted in your transcript, and a coaching pointer for each. BUILT FOR PEOPLE WHO SPEAK FOR A LIVING — and everyone who wants to. Team leads, managers, students, interviewees: if your words carry your career, Orator sharpens them. • PRACTICE & SCORE — Speak on a topic and get a 0–100 score. Short sessions cap low; the "Presidential" rank takes two sustained minutes. Excellence has to be earned. • YOUR TRANSCRIPT, MARKED UP — Tap any highlight to see the stronger alternative: "I'll try" becomes "I will." "Very good" becomes "superb." • AI DEEP COACHING — Your personal coach reads your exact words and rewrites your weakest moments into their strongest versions. Three free analyses a day. • THE LEXICON — 288 upgrades across eight categories: everyday words → presidential words, weak phrases → compelling ones, plus sentence structures (PREP, STAR, BLUF), persuasion techniques, leadership language, negotiation, and meetings. • DAILY DRILLS — Zero-filler challenges, conviction drills, evidence drills, and a rotating daily challenge with pass/fail grading. • PLAYBOOKS — Prepping a salary negotiation, interview, or hard conversation? Get exactly the patterns for that moment. • FLASHCARDS — Spaced repetition turns the upgrades into reflexes. • PROGRESS — Score trends, week-over-week habit tracking, personal bests, streaks, and playback of your own recordings.
