Using ContextOS with ChatGPT Projects

ChatGPT doesn't sit inside your file system, so the workspace travels to it: instructions become project files, and folders get attached per task.

Setup

Once per project:

  • Create a new Project in ChatGPT.
  • Upload the contents of AI Instructions/ as project files.
  • Paste the system prompt from claude.md into the project's custom instructions.
  • Per task, attach the folder that matters — Meetings/ for a status note, Customers/ for a persona question.

Working rhythm

Because ChatGPT sees snapshots rather than the live folder, the habit that matters is re-uploading changed files at the start of a work block. Keep it cheap: attach only the folder the task needs.

TRY THIS PROMPT
Turn today's notes in Meetings/ into three follow-up tasks, formatted per the conventions in my project instructions.

Round-tripping output

Paste results back into the workspace as new Markdown files in the right folder. The workspace stays the single source of truth; ChatGPT is a visitor, not the archive.
