c0mn

A commonplace for the web

The URL is the raw material.

c0mn is a visual archive for collecting inspiration without turning every discovery into a new piece of content.

Save the address of something meaningful. The original source stays intact while tags and notes give it a place in a collection that becomes more useful over time.

How it works

From open tab to a saved, stylized reference

  1. 01 / Capture

    Start with a URL.

    Paste a link to an image, article, video, song, tool, or anything else worth returning to.

  2. 02 / Context

    Add what matters.

    c0mn infers the source and media type. Add tags and Markdown notes to record why it belongs.

  3. 03 / Connect

    Browse the collection.

    Search and filter a visual masonry archive where relationships emerge across sources and subjects.
