Ondoku has many features you might not know about yet! Why not master them to make using Ondoku even more comfortable and enjoyable?
In this article, we will introduce Ondoku's features:
about these topics.
Ondoku has a feature that allows you to share the Ondoku audio you have created.

The Share button is located at the bottom of the text box, to the right of the Download button.
The button appears as soon as the audio is created after clicking the Read Aloud button.


By making it public, you will be able to share it on Twitter (X), Facebook, and other platforms.
If "Make Public" is not checked, you will not be able to share it.
Clicking the URL will display the Ondoku history page.
By making it public and sharing the URL, anyone can listen to the audio created with Ondoku and view the text that was read aloud.
Example: You can view items that have actually been made public by searching for terms like "listen to this ondoku3.com" on Twitter (X).
Even if it is made public, this page is set so that it is not indexed by Google.
Some people worry that if they have a blog post read aloud and then make it public, "the published text will be duplicated and affect the original site," but these public settings have no impact on search engines.
By clicking the Embed Tag button, you can copy source code like the following with one click.
When you paste this source code into a blog or similar site, a playback bar like this will be displayed.
This tag is very convenient when you want to paste audio into a blog.
Please make use of it.
"Public" is not required to use Embed Tags.
You can use it simply by clicking the Copy Embed Tag button and copying the tag.

If you are a free member and plan to use it for a long period, we recommend downloading the MP3 file yourself before embedding it.
If you are considering moving from a paid membership to a free membership, downloading is also recommended.
For free use, the audio storage period on Ondoku's server is 30 days. After 30 days, it will be deleted and you will no longer be able to listen to it.
If you subscribe to a paid plan (from 200,000 characters / 980 yen), the audio will be stored until the user deletes it during the subscription period.
*If you cancel, you will become a free member and the storage period will be 30 days, regardless of when it was created.
It would be a waste and a shame if you could no longer listen to the audio you worked hard to create.
Please understand the specifications and make good use of the features to enjoy using Ondoku.
