Claude Projects keep your instructions, files, and chat history in one place — so you stop burning the first 200 tokens of every conversation re-explaining yourself.
3-minute setup
- Create a project named after the outcome — e.g.
Weekly newsletter, notWriting stuff. - Paste your tone guide, audience brief, and banned phrases into Custom instructions.
- Upload 2–5 reference files: brand guide, past top-performers, FAQ doc.
Daily habit
Open the same project every session. New threads inherit everything. No more "as a reminder, I sell handmade leather goods to…"
What to put in custom instructions
- Role — "You are my senior copywriter. You know my brand inside out."
- Tone — 3 adjectives max: "direct, warm, never corporate."
- Banned words — list them. Claude will avoid them without being reminded.
- Output format — "Always return a headline, a subhead, and 3 bullet points."
Pro tip
Name projects after outcomes, not topics. Q3 launch copy beats Marketing. You'll find them faster when you have 20 projects running.
