Your voice. Your AI. Everywhere you write. Post With AI is a local-first writing studio and custom iPhone keyboard that helps your words sound clearer, stronger, and unmistakably yours. WRITE IN YOUR VOICE Create a personal Voice Profile with your tone, style, audience, and writing rules. Post With AI uses that context when shaping your words. WORK ANYWHERE Use the custom keyboard in social apps, notes, messages, email, and anywhere else you type. Rewrite, proofread, sharpen a hook, shorten a draft, or adapt it for a platform without leaving the app you are using. A STUDIO FOR BETTER DRAFTS Draft and refine longer ideas inside Studio, compare changes, undo or redo edits, and share when the words feel right. PLATFORM-AWARE WRITING Choose profiles for X, LinkedIn, Instagram, Facebook, Threads, Bluesky, Reddit, and more. Each profile guides structure and tone without posting on your behalf. PRIVATE BY DESIGN Writing, Voice Profiles, and preferences remain on your device and in your private App Group container. There is no Post With AI account, backend, social login, scheduling service, or server-side storage. AI writing uses Apple’s on-device Foundation Models on supported devices. FREE, PRO, OR LIFETIME Free includes 15 successful AI edits each month. Pro Annual and Lifetime unlock unlimited AI editing. Keyboard typing always remains available. Post With AI helps creators, founders, professionals, and anyone with something worth saying write with more confidence—without becoming generic AI.
