What format does Cortex use for notes?

Cortex uses Obsidian-flavored markdown, supporting wiki links ([[Topic]]), task lists, and callouts, making it perfectly compatible with local note-taking apps like Obsidian.

Can Cortex summarize websites?

Yes. When you paste a URL without context, Cortex offers to fetch the content, summarize it based on your focus, and append the summary to your daily notes.

Where are my notes stored?

Your notes are stored in a GitHub repository of your choice, which you can configure in the skill's config.json file using a Personal Access Token.

How does Cortex handle task management?

It automatically identifies action items, next steps, and explicit TODOs within your conversation and moves them to a dedicated '# Todos' section at the top of your daily note file.

How does it handle different timezones?

Cortex reads a timezone setting from its configuration to ensure that daily notes are timestamped and named according to your local time rather than UTC.
