01
Paste or import source data
Users should be able to start from text, lists or simple files without setup overhead.
02
Review the cleaned result locally
The interface should make differences visible before someone copies or downloads the final output.
03
Copy or export with confidence
The handoff step should be obvious and fast, especially for small admin tasks done under time pressure.
FAQ
Common questions before you start.
Will data be uploaded to a server?
Supported tools process your files and text in the browser. The site does not include a mechanism that sends those inputs for AI training.
Can I switch between Japanese and English?
Yes. Routing and UI copy are structured around both `/ja` and `/en`, and the language switcher is available directly in the header.
Will the tools work on mobile?
The site is responsive, but larger table and file workflows will still feel better on desktop. Simpler text cleanup should remain usable on phones.
