Penpal 智能输入

Penpal is a smart keyboard built for language learners. Practice as you type, and turn every input into an opportunity to improve. Supports English, Japanese, Korean, Cantonese, French, German, Spanish, and more — with instant professional feedback for both typing and voice input. Key Features: • Smart Grammar Check After typing, tap to check. Penpal reviews your text against your learning goals, suggests more natural phrasing, and explains the reasoning — so you understand not just what to fix, but why. • Natural Translation Translate your thoughts into authentic, natural expressions in your target language. No more stiff, word-for-word translations — write like a local. • Pronunciation & Reading Aloud Tap any suggested correction to hear its standard pronunciation, and repeat along until the phrase truly rolls off your tongue. Perfect for you if: • You want to chat, email, or post in a foreign language but aren't sure your phrasing sounds natural. • You're learning a language and want to grow a little with every message you type. • You communicate in a foreign language often and want to cut down on grammar mistakes and sound more professional. About Privacy: Penpal requires no sign-up and no login, and collects no personal identity information. Grammar checking and speech recognition require sending your text and voice to third-party AI services, where they are processed and immediately discarded. We do not store any content for the purpose of identifying you. See our Privacy Policy for details.
