[Updated as needed] A summary of useful tools created by note creators: From writing and reading to analysis and image creation
As you continue using note, there are times when you might feel, 'I wish this part were a little more convenient.'
I want to search for past articles
I don't want to forget to reply to comments
I want to record my daily numbers
I want to shorten the time spent thinking about titles and hashtags
I want to display images and videos beautifully
When I looked into it, I found that note creators themselves have made various tools to solve these problems.
However, tools developed by individuals are often introduced within each creator's own articles, making them difficult to find as time passes.
Therefore, in this article, I have taken the liberty of summarizing tools that seem useful for people who write, read, and interact on note.
This includes not only free tools but also paid ones, those under development, and those where you implement the code yourself. Since availability, terms of use, and operating environments may change, please be sure to check the author's article before using them.
Also, I have excluded from this list items that require careful judgment regarding note's terms of service, such as automatic posting to note, automatic customer acquisition, or large-scale/continuous data acquisition of third-party accounts.
The listed tools are not necessarily provided or recommended by note officially. Please use and implement them at your own risk after checking the author's explanation and note's terms of service.
Also, since I have posted these without permission, please contact me if the content is incorrect or if you would like me to stop listing your tool. I will correct or delete it.

Summary
Before I started researching, I didn't realize that so many different tools had been created.
However, introductory articles can get buried over time, and sometimes you can't find them because you don't know the name of the tool.
Therefore, I don't intend for this article to be finished once published; I plan to update it as needed within reasonable limits. I'm not sure if I can do it, though ☺️
Regarding the tools listed, I will do my best to correct information if I confirm that they are no longer available, have changed pricing, or have had specification changes.
Thank you to everyone who created and released these tools.
I hope this article serves as a list that connects people who want to use note a little more conveniently with those who have created useful things.
