This App Really Helps

This app is a great companion for language learning. One of the hardest things is practicing what one has learnt in a relatable way, and this is exactly what Sylvi does. The grammar tips and reasoning behind why something has been corrected are so helpful for learning. I think the team has done a fantastic job. Since I started using Sylvi, I’ve noticed that my conversational skills have vastly improved. I also really appreciate the weekly report, it is encouraging but accurate in its assessment of where I land on the CEFR scale. Sylvi is part of my essential app collection for language learning.

The best app for practicing Spanish conversation

The app just works, plain and simple. The penpals speak naturally about things I want to talk about. The app marks my mistakes and actually explains why and gives suggestions. I can save the words I don't know into a spaced repetition flash card feature. There are settings to customize if I want to practice writing and reading messages or speaking out loud and listening to the responses.

I also take Spanish classes but I don't get enough practice with conversation in class, so this app is the perfect supplement for my needs.
I use Sylvi every day, and the improvements I've seen in my speaking confidence and language recall make it worth the cost of the subscription.

Response from developer

Wow thanks Brose0B for such an informative and glowing review. Really happy the penpals are talking about the things you actually want to talk about, and that the corrections come with the why rather than just a red mark. And it's great to hear it's slotting in alongside your classes. That conversation gap is exactly what we built Sylvi to fill, so hearing your speaking confidence and recall have come on is brilliant. Please tell all your classmates about us!! And buena suerte with your Spanish! Best, Sam 🫶

Great app to learn a language

I enjoy the concept of being able to talk to AI penpals that don’t sound robotic but almost like real people. The corrections made by the app are quick and thoroughly explain the mistakes that were made. It’s a good alternative to speaking to real native speakers if you don’t know any or can’t speak with one often.

Thanks so much for the review Luca! Really happy to hear the penpals have landed well, as well as the corrections and explanations. Thanks for choosing Sylvi and good luck with the rest of your language learning! Best, Sam 🫶

The Best Language Learning App

I am using this app to learn Italian and I can I just say…wow. I have never come across a more intelligent learning system for mastering a language. The premise is that you speak and chat with a language partner. But instead of a real person it’s an AI partner. However you wouldn’t be able to tell because they respond so naturally, like a real person. The accents and conversation are so believable. I feel like I am talking to an old friend! I love that Sylvi corrects my grammar and provides explanations. I then can practice my mistakes and new vocabulary in the lessons and flash cards. Then there’s a feature that lets you read and discuss the news. It’s truly worth the annual fee.

simbeach - wow what a review! Thanks so much. Really happy Sylvi's landing so well for your Italian. Feeling like you're chatting with an old friend is exactly what we hope for with the penpals. Also brilliant to hear the corrections and explanations are working well for you, and that you're taking those mistakes and new words straight into the lessons and flashcards. In bocca al lupo with your Italian! Best, Sam 🫶

The best language app

As someone who has been learning Spanish on and off for YEARS, I have tried countless apps to help me learn and I can confidently say none of them come close to Sylvi.

I’ve always struggled to be consistent but I’ve found myself on the app every day for nearly a month now. It’s like having a tutor & a friend to speak to combined into one. The lessons, the flash cards and the conversational practice have honestly taken my Spanish skills much further in the space of a month in comparison to any of the other apps over the space of years.

Thank you Sylvi!!!

Thanks so much for the review tlelove2! It means a lot to hear Sylvi's the app that's finally stuck. Love 'a tutor and a friend combined into one' as a way to describe it. Really happy the lessons, flashcards and conversation practice are all working well for you. Buena suerte with your Spanish! Best, Sam 🫶
