📝 About this app
Sakuraspeak offers a unique, fun, and faster way to practice Japanese & Korean through role-play scenarios, designed for both language learners and travelers.
“Speaking Japanese used to feel overwhelming whenever I needed to include specific details like dates, times, or numbers in a sentence. I’d get stuck halfway through and wasn’t sure how to connect everything properly. For instance, I wanted to say, ‘I’d like to make a dinner reservation for 2 people on Saturday at 6 pm,’ but I couldn’t figure out how to piece it all together. Thanks to Sakuraspeak, I was able to complete the sentence effortlessly. The app has been a lifesaver for those moments when I know part of what to say but need help to finish it confidently.” - Amanda D.
“Your AI product is exactly the kind of thing that I've been hoping to find and to come to exist." - Thomas, Korean language learner for 20 years
"So far I'm really liking the app. I've been using it to ask grammar questions and its been really useful. get to practice speaking and do some grammar study at the same time." - Crater
“Before using Sakuraspeak, I struggled with speaking Japanese confidently because I wasn’t sure if I was making mistakes or using the right grammar. It was frustrating not knowing how to improve. With Sakuraspeak’s correction and explanation features, everything changed. The app not only points out my mistakes but also explains them clearly, so I can learn and avoid repeating them. Thanks to Sakuraspeak, I’m building confidence in speaking Japanese and making real progress every day!” - Benjamin
