How do I sign up for ChatGPT or Claude without doing something wrong?

You Cannot Break Anything During Signup

The first thing to know: there is nothing you can do during the signup process that causes a real problem. No trap doors, no accidental purchases, no permanent commitments unless you deliberately enter a credit card and confirm a paid plan. Both ChatGPT and Claude have free tiers you can use indefinitely.

Signing Up for ChatGPT (Step by Step)

1. Go to chatgpt.com
2. Click the "Sign up" button (top right)
3. Enter your email address and create a password — or use "Continue with Google" if you have a Google account
4. Verify your email address by clicking the link they send you
5. You are in — no payment required

The free tier gives you access to GPT-4o with some daily usage limits. You will not be charged unless you voluntarily click "Upgrade to Plus" and enter a credit card. That upgrade is optional and costs about $20/month.

Signing Up for Claude (Step by Step)

1. Go to claude.ai
2. Click "Sign up" or "Continue with Google"
3. Enter your email or use your Google account
4. Verify your email
5. You are ready to use Claude for free

The free tier of Claude is generous. You get access to Claude Sonnet without a credit card. Paid plans (Claude Pro) exist but are completely optional.

Three Common Signup Mistakes to Avoid

Mistake 1: Signing up on the wrong site. There are sites that look like ChatGPT but are not. Always go directly to chatgpt.com or claude.ai — type the URL yourself rather than clicking ads.

Mistake 2: Entering a credit card "just to verify." Neither ChatGPT nor Claude requires a credit card for the free tier. If a site asks for one before you can do anything, you may be on the wrong page.

Mistake 3: Creating multiple accounts. You only need one account per tool. One email, one account — that’s it.

After You Sign Up

Once you are logged in, you will see a text box at the bottom of the screen. Type your first question or request there. That is the entire interface. Start with something low-stakes like "Explain what a learning objective is in plain English" to get a feel for how the tool responds.
