Overview
Smart Keys is an AI-powered keyboard designed for iPhone, iPad, and Mac that polishes writing in real time, offers on‑the‑fly translation, and supports customizable Smart Keys (AI shortcuts) for quicker workflows. The app highlights real-time proofreading, tone adjustments, and clarity enhancements, plus context‑aware smart replies and image-based text generation from uploaded images. It integrates with external Bluetooth keyboards on iPad and Mac, offering a Touch-Bar–like row of keys, and ships with built‑in playful utilities (jokes, rhymes, horoscopes, kaomoji). Pricing is freemium, with a Free tier and a Pro subscription that unlocks advanced proofreading, full translation including screenshots and conversations, custom AI keys, text‑to‑speech, image-based generation, and enhanced keyboard integration. The site smartkeys.so currently returns 404 for Docs/Support/Features/Pricing/Contact pages, so the App Store listing is the primary source for detailed feature descriptions and pricing.
