// CHATGPT + CODEX

ChatGPT can run your errands and write code while you sleep.

Set it up once, and it briefs you every morning, does your research legwork, and builds small tools on its own. Here’s the hour that gets you there.

Get useful criticism of a draft

Paste a draft you are permitted to share and ask for a ranked critique before requesting a rewrite. This keeps the review focused on weaknesses you can evaluate.

From The OpenAI Stack, “Writing & Thinking”

Be my toughest fair reader: where is this unclear, unsupported, or boring? Rank the three biggest problems before suggesting fixes.

Check the result before using it

  • Ask the reviewer to point to the exact passage behind each criticism.
  • Verify factual objections against the original source rather than accepting the model’s confidence.
  • Revise one issue at a time, then compare the draft with your intended audience and purpose.

// the problem

You’ve got a powerful tool, and most of it is switched off.

Every session, you re-explain who you are and what you’re working on, then copy answers in and out by hand. Meanwhile the features that remember you, organize your work, run tasks on a schedule, and write code on their own are all sitting right there — a big chunk of what you pay for that most people never open.

// what you’ve tried

You’ve poked at the rest and bounced off.

Switched on memory once and couldn’t tell if it changed anything

Started a Project and wasn’t sure what to put in it

Heard it could act on its own and quietly closed the tab

Nobody sat down and showed you the setup. These features are genuinely useful but poorly explained, so they feel risky instead of helpful — and you go back to the chat box because at least that part is clear.

// what changes

Here’s what the guide covers.

Set it up once, then hand off real work every day.

Spend one hour getting it set up properly. After that, you give ChatGPT actual jobs and step away — the words to type, the safety checks for letting it act on its own, and code that gets written while you sleep.

// before you ask

A few fair questions.

What should I check before using the guide?

Read the chapter list and examples to see whether the guide fits your task. The documents describe a June 2026 snapshot. Product features, access and pricing can change, so confirm any setup instructions against current vendor documentation.

Do I need paid software?

The download is free. Some workflows may require a product account, subscription or hardware. Check the requirements for the workflow you choose before buying or installing anything.

Will a prompt always produce the right answer?

No. Check factual claims, calculations, citations and any output you plan to publish or act on. Use information you are permitted to share and keep consequential decisions under human review.

How do I get the full guide?

Enter your first name and email in the download form. The guide is offered as a download and an emailed copy. No payment card is required. You can unsubscribe from subsequent emails.

Hand off your first job this week.

Grab the Power Guide, spend the setup hour, then send ChatGPT off to do your research, draft your report, or build you a small tool. Free, takes a second, yours to keep.
