Every week I use Codex to batch-add Frontmatter to my documents.
Frontmatter is the section at the beginning of an Obsidian note used to store metadata. It contains key information about the note, such as tags, dates, categories, authors, and so on, and it is structured. That way, Obsidian and plugins can accurately find, filter, sort, and aggregate these notes by field, instead of forcing me to dig through the body for keywords.
I used to do this step manually. Now I just need to have Codex refer to past practices and tags (for the same topic, they can be reused; there’s no need to create new tags) and add them to the new document.
Anyway, Codex has plenty of quota, so it doesn’t hurt to use it.
At this stage, between OpenAI and Anthropic, whoever can keep me fed will come out on top.
