Sylvi

What’s unlocked in this version

Sylvi: Language Penpals mod for iPhone now comes with the app’s subscription unlocked, giving you full access to the premium features in the updated IPA.

Sylvi: Language Penpals lets you download Sylvi IPA for iPhone or download for iOS and turn language practice into a real conversation instead of another drill set. With AI penpals that respond like native speakers and give tutor-style corrections on every message, Sylvi is built for anyone who wants a more natural way to practice before speaking with real people. On builds.io, you can get the IPA and install it in one tap, no PC required.

Sylvi focuses on the part of language learning that most apps skip: using what you know in a way that feels useful in daily life. You can chat with penpals in the accent you want to hear, whether that means French from France or Canada, Spanish from Spain, Mexico, Colombia, or Puerto Rico, plus German, Italian, Portuguese, and English varieties from the UK, US, and Australia. Each exchange helps you practice the phrases, tone, and confidence that matter when the conversation becomes real.

Instead of only marking mistakes, Sylvi explains them so you understand what to change and why. That makes it easier to build vocabulary around your own interests, save important words, and review them later so they stick. It also gives you a way to practice with friends and stay accountable even if you are all learning different languages or working at different levels.
