A must-read for anyone looking to promote an AI tool. A curated list of 10 platforms — primarily Japan-based — where you can list your tool at no cost. Covers platform features and submission methods, helping individuals and businesses alike take their first step toward customer acquisition.

Every service listed is actively operating, and all have been selected because they are open to both individual developers and companies.
