My partner and I built Daily Tokki (https://dailytokki.com?ref=hn-1), an email-only app designed to help people learn Korean or English through personalized daily questions. My partner is a Korean native fluent in English, and we created this app because many language-learning apps cap out after beginner material, leaving learners unsure how to progress further.

Here’s how it works:

1. Each weekday, you get a short, personalized question in your inbox.

2. Reply to the email with your answer.

3. Daily Tokki analyzes your response, provides corrections, and tracks your progress.

The goal is to provide meaningful, consistent practice without the distractions of traditional apps. There’s nothing to install—just check your email, respond, and improve.

We wanted to create a tool that supports learners at all levels, offering tailored questions that grow with your abilities. It’s perfect for busy people looking to build a daily habit or for those who want more advanced material than typical apps provide.

We’d love to hear your feedback about the concept, how it could be improved, or anything else you’d like to share. If you’re learning Korean or English, give it a try—we’d love to know what you think!
