Projects: give your work a home.

Scattered one-off chats are where good work goes to die. Projects bundle the files, the instructions, and every conversation about one piece of work into a single space that remembers — and that changes how much ChatGPT can carry for you.

01 What a Project actually is

A Project is a folder with a brain. Inside it: files you upload once and reference forever, project instructions that apply to every chat inside (separate from your global custom instructions), and all the chats about that work in one list. New conversations in the project start already knowing the files and the rules. That's the difference between re-briefing a temp every morning and working with a colleague who was here yesterday.

02 What deserves a Project

One honest anti-pattern: a project named "Misc." If it doesn't have a shared context, it's just a chat. Let one-offs be one-offs.

03 Project instructions: the 80/20

The highest-leverage text you'll write. A strong template:

Template

This project is: [one sentence]. Key facts: [3–5 bullets the model must never get wrong — names, prices, dates]. Always: [voice, format, defaults]. Never: [the mistakes that matter — "never quote delivery under 2 weeks", "never use the old logo colors"]. Files: [one line on what each uploaded file is for].

Keep it under a screen. Instructions rot when nobody re-reads them — prune every few weeks, exactly like you'd prune a real project brief.

04 Working patterns that compound

One chat per deliverable, not one endless chat. "Bid letter — Hendersons," "Q3 pricing update." The project holds the shared memory; chats stay findable.
End work sessions with a handoff: "Summarize what we decided today and what's still open." Paste it into the next session — or just start the next chat with "check the last chat's summary."
Refresh stale files. When the price sheet changes, replace the file the same day. A project confidently citing last quarter's prices is worse than no project.
Try it now

Create one project for your messiest ongoing work. Upload the three documents you keep re-attaching, write instructions with the template above, and run the first chat: "Based on the files, what do you know and what should I add?"

This week's challenge

Move one real, active piece of work fully into a Project — files, instructions, and all future chats. Use it exclusively for a week, then open your old scattered chats about the same work and feel the difference. You won't go back.
