I'm using the Web IDE to take notes in most of my projects, work and personal, and publish the notes with MkDocs and GitLab Pages to a searchable frontend/domain when needed. Editing also happens in Gitpod with live preview in the browser.
You can find all resources for o11y.love [0] and opsindev.news [1] in the GitLab projects, including .gitpod.yml configuration, mkdocs.yml setup, .gitlab-ci.yml deployments.
I have been writing lots of documentation in my past OSS projects, so I am used to Markdown as markup language, taking notes very fast. Learning Markdown requires some practice, and can be helped within Gitpod and the VS Code extensions, if the default preview is not sufficient. [2] [3] You can also sync the notes repository offline into VS Code as desktop IDE for example.
Using Obsidian.md to take notes and publish with GitLab pages [4] looks promising too; I have not tried it yet.
