# Revert > Revert is an AI keyboard for iOS and Android that generates context-aware reply suggestions, rewrites your tone, and translates messages in real time — inside any app you already use. Free with Revert Pro available at $4.99/month or $39.99/year. Revert ("Revert AI") is built by Abiomye Industries Private Limited. It replaces your phone's standard keyboard with an AI-powered alternative that works system-wide in WhatsApp, iMessage, Gmail, Slack, dating apps, and any other app that accepts text input. The AI runs partly on-device (Apple Foundation Models on iOS 26, Gemini Nano on Android) with a secure cloud fallback through Revert's own server (api.gorevert.com) for older devices and heavier requests. User profiles and preferences are stored only on the user's device. The OpenAI API key is never embedded in the app binary.
