How to set up Claude in one day. The way you set it up matters way more than any prompt or skill you use, and most people skip a couple of these and wonder why it feels basic.
If you're new to Claude, the way you set it up matters way more than any prompt or skill you use.
Most people skip a couple of these, then wonder why Claude feels just like ChatGPT back in 2022. Do these five first and it turns into something that actually knows you and reaches into your real work. You can knock all five out this afternoon.
Work in the desktop app instead of your browser. This is the one most people skip, and it's the biggest, because the app can actually reach the files and apps on your computer. Instead of copying and pasting everything in, Claude works with what's already on your machine. It's free and takes about two minutes to set up:
From now on, do your work in the app. That single change is the difference between a chatbot and an assistant that's actually in your workflow.
This is where you tell Claude who you are and what you do one time, and it carries that into every single chat so you never repeat yourself again. Here's exactly where to put it:
The hack most people miss: be specific, and tell it what to stop doing. Things like "push back when I'm wrong," "no em dashes," or "keep answers under 150 words." Telling it what not to do is often more powerful than telling it what to do. Here's a template you can paste straight in and edit:
Connectors link Claude to apps you already use, like Gmail, Google Drive, Calendar, and Notion, so it can read your real emails, docs, and notes instead of you copying and pasting them in. This is where it starts saving you hours a week. Here's exactly how to add one:
To actually use one in a chat, click the + in the bottom-left of the message box, hover over Connectors, and switch on the ones you want for that conversation. Then just ask like you'd ask a person: "check my calendar for tomorrow," or "find the invoice email from Sarah and summarize it for me."
Do This Safely
You stay in control the whole time. You sign in through each app's own login, so Claude never sees your password, and it asks before it does anything. Good to know: Claude can read your email and write drafts for you, but it can't actually send them, you always send those yourself. Only connect tools you trust, skip anything tied to money or private client data until you're comfortable, and you can disconnect any tool in one click under Customize, then Connectors, anytime.
You can switch which model you're using anytime. Just click the model name at the top of your chat (or right under the message box when you start a new one) and pick a different one from the list. You can even change it in the middle of a conversation, and it kicks in on Claude's next reply. Most people never touch this, but it changes how good your answers are.
The names change every few months, but the rule doesn't: the heaviest model for the hard stuff, the lightest for the quick stuff.
A project keeps a whole part of your life or work in one place. Everything you drop in stays there, and Claude remembers all of it across every chat inside that project. Here's how to make one:
Say you're job hunting. You'd drop your resume and cover letter into the files, and put your work history, where you want to work, and your skills into the instructions. Now every conversation in there already knows your full situation. Start with one area, then spin up a separate project for each big part of your life: one for your job, one for your side hustle, one for personal stuff. Each one stays its own world.
The Real Win
Prompts and skills are what you do after setup. These five are the foundation that makes all of them work. Knock them out once and Claude stops feeling generic and starts feeling like it's actually yours.
