Suikō: Japanese Journal

Japanese writing practice for intermediate to advanced learners. Write an entry, and get feedback on mistakes in grammar, particles and word choice. You fix each mistake 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. Rewriting yourself is 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 suggestions to challenge yourself to use new grammar – A daily reminder to keep your writing habit consistent – Streaks to encourage you to show up every day FIX IT YOURSELF – Mistakes are marked without directly rewriting your entry – Each mark names the word, particle or grammar form that would fit more naturally instead – Up to 10 rounds of feedback on each entry, each round checks which of your fixes worked – 1 premium editor pass to strengthen your writing, fix what sounds stiff or translated, and rate the JLPT level your writing shows – A satisfying seal to mark your entry as complete A PAGE MADE FOR JAPANESE – Vertical (縦書き) or horizontal writing – Ruled lines or a blank page KEEP EVERYTHING – Every entry and every version of it, in your archive – Search everything you've written – Export your journal as a spreadsheet FREE TO WRITE, SUBSCRIBE FOR FEEDBACK Writing is free: the prompts, grammar suggestions, and viewing your old writing in the archive. You get AI Feedback by subscribing to The Editor: $9.99 a month or $99.99 a year in the US (prices vary by country), with a 7-day free trial for new subscribers. Payment is charged to your Apple ID.

YOUR WRITING IS PRIVATE There's no feed and nothing is shared. Your text goes to Anthropic and Google for feedback only when you tap Get feedback, and only after you've allowed it. For learners at roughly N3 to N1 and beyond who can already write a few sentences on their own. Feedback is tuned to the level you choose. 推敲: to polish one's writing.
