Notice of Price Changes Due to Incorporation for Ondoku Users
Jan. 26, 2026
We would like to express our sincere gratitude for your continued patronage.
Today, we are announcing the incorporation of Ondoku operations and a price revision associated with this incorporation.
Notice of Incorporation
We are pleased to announce that the operation of Ondoku has changed from its status as a sole proprietorship, "comomo,"
and as of August 30, "Kabushikigaisha San" has been newly established.
We are deeply grateful for this, which is entirely due to your warm support.
In the future, as a service that aims to be the most user-friendly speech synthesis tool connecting AI, people, and things,
we will give back to our users through various functional updates to make it more convenient than ever before,
and by providing enhanced security for safe and secure use.
We will make every effort to meet your expectations.
We humbly request your continued support and patronage.
