Read full descriptionHide full description
Ever wish you could say something in a completely different voice - funnier, more dramatic, more poetic, or just way more interesting? AlterEgo is an AI-powered custom keyboard that instantly rewrites your messages in the voice of any persona you choose. Type your message. Pick an alter ego. Watch your words transform. HOW IT WORKS 1. Add AlterEgo to your iPhone keyboard (takes 30 seconds). 2. Open any app where you type - Messages, Instagram, Notes, WhatsApp, email, anywhere. 3. Scroll the persona rows at the top of the keyboard and tap any Alter Ego. 4. Your message is instantly rewritten in that character's voice - slang, tone, style and all. --- 250+ UNIQUE ALTER EGOS Choose from 250+ unique characters across 8 categories: - Classics: Shakespeare, Wild West Cowboy, Victorian Aristocrat, Film Noir Detective & more - Superheroes: Caped Crusader, Friendly Neighborhood Hero, Galactic Guardian & more - Sci-Fi & Space: Rogue Starship Captain, Time-Traveling Scientist, Alien Ambassador & more - Fantasy & Magic: Ancient Wizard, Dragon Whisperer, Elven Archer & more - Sports: NBA Hardcourt Fanatic, Football Superfan, Soccer Ultra & more - Pop Culture: K-Pop Stan, Marvel Devotee, Swiftie, Cinephile & more - Lifestyle: Wellness Guru, Foodie, Bookworm, Fitness Coach & more - Regional: Surfer, Southern Belle, New Yorker, Texas Cowboy & more --- SMART REWRITES AlterEgo's AI doesn't just slap a theme on your message - it understands context. A casual "what's up?" gets a quick, punchy reply. A venting message gets a more dramatic, emotionally aware response. Every persona has its own signature moves, catchphrases, and speech patterns. --- FAVORITES Long-press any persona on the keyboard to instantly save it to your Favorites row for one-tap access. --- REWRITE HISTORY Every rewrite you keep is saved to your History tab in the AlterEgo app. Browse past rewrites, share them as cards, or use them for inspiration. --- Subscriptions auto-renew unless cancelled at least 24 hours before the renewal date. Manage or cancel anytime in your Apple ID settings. --- AlterEgo requires "Full Access" to enable AI rewrites. No personal messages are stored on our servers. Rewrite requests use only the text you actively select for transformation. ---- SUBSCRIPTION DETAILS ---- 5 free rewrites per day, no account required. AlterEgo Pro unlocks unlimited rewrites and all 250+ characters. Three plans available: • Weekly: $2.99/week • Monthly: $5.99/month • Yearly: $24.99/year A 3-day free trial is available for new subscribers.
