Here's the story for why I built this app:

After achieving a 1,000 day streak learning Chinese on another popular language learning app, I realized that I didn't really know Chinese. Sure I could say things like "I like cats and dogs" but I couldn't say anything of real substance. And if I heard someone speaking Chinese, there was exactly a 0% chance that I would understand them. So I started looking for a better way to learn Chinese.

I came across this idea of "comprehensible input" by Stephen Krashen which basically says in order to learn a language, you need to be exposed to lots of language material that's slightly above your current level. I was fascinated and wanted to try it so I started looking for Chinese content.

A few things became clear to me:
1. Reading content in another language takes a lot of effort.
2. Studying becomes easier if the content is something you're interested in.
3. It's hard to find content that's both at your level and interesting.

You can see where this is going... I built 7fish to solve these problems. The main thinking was that if I could make reading less of a chore and more fun, then I could actually learn Chinese. I tried using ChatGPT to accomplish my goals but luckily for you, the process was too clunky and the overhead was too high. I needed something more streamlined. So 7fish was born and now you can learn a language with it too.

7fish uses AI to generate stories that are both interesting and slightly above your current level. You simply specify what you want the story to be about and voila, the AI will give you a story about that.

7fish makes it easy to learn new words. Long-press a word to see it's pronunciation and definitions. Tap a sentence to see the English translation. Press the playback button to have the story read aloud to you.

7fish tracks your progress over time. The AI knows which words you're currently learning and will intentionally include them in the stories. Additionally, the stories will become more complex and have richer vocabulary as your proficiency grows.

I've made the app free to use with ads. However, there are a few premium features that you can unlock through subscriptions:
1. Device syncing - you can access your progress / stories on any device (iPhone, Android, etc.).
2. AI chat bot - while reading a story, you can ask the AI questions about the grammar, vocabulary, or anything else related to the story.
3. Weekly saga generation - sagas are multi-chapter stories. Because sagas are longer, you can have more interesting and complex stories.

Try reading 1-2 stories per day with 7fish. Keep it up and hopefully one day you'll be fluent in that language that you've always wanted to learn.
