Writingpad.io is an online tool which helps you to create notes quickly.
As a developer, I often times have to copy things such as code, API calls, etc. make some changes to it and paste it. I have used Notion , Google notes, Apple notes in the past, but each of these either needs login or to install application to use.
How to use this
Writingpad.io is a free to use tool that doesn't even require account. You can just go to the application and start using it directly. You can also use Markdown language to create various components such as Headings, URL tags, etc.
