Submit or correct a product listing

Chinouken is a Japanese publication that helps readers assess AI and software for real work. Our directory explains pricing, trial limits, availability from Japan and other details people need before trying a product. If you provide a service, you can submit it or correct an existing listing here. Both are free.

What you can send us

  • A product we have not listed yet
  • A factual correction to pricing, features or availability on an existing page

Our editors decide whether to list a product and how to describe it using the information readers need and the facts we can verify. Payment does not change ranking or editorial conclusions. Products based in Japan are welcome under the same criteria.

Read our editorial policy (Japanese only) for our listing and advertising rules. For interviews, partnerships or AI implementation work, use our contact page. The Japanese form is at /submit.
