About Suikō: Japanese Journal

Japanese writing practice for intermediate to advanced learners. Write an entry, and get feedback on every mistake in grammar, particles and word choice. You fix each one yourself, so the phrasing you end up with is yours. Suikō turns writing practice into a routine you can keep. You write an entry. Tap Get feedback, and AI marks each mistake on the words you wrote, with a short note on what's wrong and what to use instead. It never rewrites your Japanese for you. The rewrite is yours, and it's how the words you've studied become words you use. WRITE EVERY DAY – A new prompt each day, so there's always something to write about – Optional grammar ideas that fit the prompt, for when you want to try out new grammar – A reminder at the time you choose – A streak that counts each day you finish an entry FIX IT YOURSELF – Mistakes marked on your own sentences, never replaced with a rewrite –…
