KOTOBA Studio — Free Japanese product-copy templates

Japanese product copy, from the facts you already confirmed

KOTOBA Studio is a free template tool. There is no sign-in, no card, and no AI generation. You type confirmed product facts. The tool fills templates for a product description, advertisements, social posts and FAQs. You edit the draft and export it as CSV or text. Drafts stay in the browser.

The current trial is in Japanese. There is no English interface. The text it produces is a draft: you should check it against your own product facts before you publish anything. This page is a request for free early access. We will write back with how to use the tool. There is no charge.

What you can draft

Product descriptions

Templates help you turn confirmed specifications into Japanese product-page copy.

Advertisements, social posts and FAQs

The same facts can be arranged into short advertisements, social posts and frequently asked questions.

You edit, then you export

You review the draft, edit it, and export CSV or text yourself. Nothing is posted to a shop or a social network for you.

What it does not do

It does not use AI writing, and it does not generate images.

It does not post automatically to a shop or a social network.

It does not legally clear the draft. You remain responsible for checking the facts before publication.

The current trial does not have an English interface.
