Check Japanese text for slips and inconsistencies

Check common spelling slips, adjective and verb endings, punctuation, bracket pairs and writing consistency. Each finding explains what to review; apply individual suggestions and undo them without leaving the page. Choose a writing context to distinguish modern prose from formal or historical writing. Your draft stays in your browser. You can also send text straight from a blog editor.

All checks run on this device. Web addresses, email addresses and backtick code are skipped. Paired 「quotes」, 『quotes』 and “quotes” are skipped for wording unless you enable the option above. Bracket pairs are always checked when Basic is on.

Read how to use it and the terms first. Nothing you paste is sent to or stored on our server.
The checker uses curated word lists and grammar patterns, not AI. It can miss errors or flag intentional wording; a clear result is not proof of correctness. For important documents, ask a qualified reader too.
