Custom Instructions
In one sentenceSaved preferences an AI applies to every chat: who you are, how you like answers, what to avoid.
What it means
ChatGPT, Claude, Gemini and others let you save information about yourself and your preferences. The AI then uses it in every conversation without being reminded.
Related features include Projects (Claude, ChatGPT), Gems (Gemini) and custom GPTs, which bundle instructions with files for a specific job.
How to use it
- Add: your role, company, who you serve, your tone, and formatting preferences ("short paragraphs", "no em dashes", "use bullet points for lists").
- Create a separate project for each recurring job (LinkedIn posts, proposals, client research) with its own instructions and reference files.
