How to set up your AI (ChatGPT, Claude, Gemini)
A good prompt gets you a good answer once. Setting your AI up properly gets you good answers every time, without re-typing the same context. Here is what the settings actually mean, in plain English.
Custom Instructions vs Projects vs agentic mode
- Custom Instructions are a note applied to every chat: who you are and how you want answers (tone, length, format). Set them once. Use them for the things you always want, like "keep answers short and skip the intro."
- Projects (or Gems) are a workspace for one topic, with their own instructions and files. Everything you chat about inside stays in that context. Use them for a class, a client, a book, or a product, so you do not paste the background every time.
- Agentic mode is when you let the AI take several steps toward a goal, such as browsing, running code, or using tools, instead of giving one answer. Use it for research or multi-step tasks, and be specific about the goal and the limits.
Rule of thumb: put how you always want it to behave in Custom Instructions, put everything about one topic in a Project or Gem, and switch to agentic mode only when the task genuinely has multiple steps.
ChatGPT
- Custom Instructions: in Settings, tell it about you and how to respond. Applies to every new chat.
- Projects: group related chats, files, and instructions in one place for a single topic.
- Custom GPTs: build a reusable assistant with fixed instructions and knowledge you can return to.
Claude
- Projects: add documents and a project instruction that applies to every chat inside, ideal for a body of knowledge.
- Styles and preferences: set a default writing style so replies match your voice without asking each time.
Gemini
- Gems: reusable custom assistants with instructions you set once and reuse.
- Saved info: facts about you it remembers across chats, so you skip the reintroductions.
How the packs work
Every prompt has a Copy button. Copy it, paste it into your AI tool, and fill in the parts in brackets like [topic] or [paste]. The prompts run entirely in your own AI account, so glunty makes no requests and sees none of your input. They are free to copy, use, and share.
