How to Build Websites with ChatGPT Codex

TL;DR

Codex lets nontechnical users modify a website by describing a task in plain language, then reviewing and merging the generated changes through GitHub. A beginner-friendly workflow is to start with a simple personal site, create one focused task at a time, check the pull request and automated checks, merge only when there are no conflicts, and confirm that the deployed site works.

Should you try Sam Alman and OpenAI's new AI engineer in the browser codecs? Well, in this episode, that's what we unpack. We do a live tutorial for nontechnical people around how to use codecs to get the most of it. Uh, I brought on Ben Tossel. He's a, you know, one of the most renowned people for explaining no code tools for non-technical people.... Read More

Key Insights

• Codex is a task-based coding tool that can inspect a connected GitHub repository, generate code for a requested change, and prepare that work for integration. The user describes the outcome in plain language instead of manually locating and editing every relevant code file.
• GitHub repositories are project containers that store code files and preserve a history of changes through commits. A user begins by creating a repository, choosing whether it is public or private, and optionally adding a README that explains the project.
• A branch is a separate version of the main codebase where a feature can be developed without immediately changing the live project. Once the work succeeds and has no conflict with the main branch, the branch can be merged back into it.
• A pull request is the review step between generated code and the main branch. It provides a summary of the work, shows changed files and automated checks, reports whether conflicts exist, and allows the user to approve the merge.
• Codex is capable of connecting a short request to multiple project files. When asked to add a food section, it created a food document and updated the main website file with a new button and tab rather than producing only an isolated text change.
• Codex does not necessarily implement related behavior that the user leaves unstated. In the demonstration, it noticed existing keyboard event listeners but did not add a shortcut for the new tab, illustrating why prompts should explicitly include every required interaction.
• A successful Codex task does not immediately appear on the live website. The generated changes must first become a pull request, pass the available checks, merge into the main branch, and complete the connected deployment process before the user can verify them online.
• The beginner workflow is best practiced with a simple personal website and focused changes. This keeps the task understandable while the user learns repositories, branches, pull requests, merges, deployment previews, and the difference between generating code and publishing it.

Questions & Answers

Q: What is Codex and what does it do for beginners?

Codex is presented as a coding tool that accepts a task written in plain language, examines a connected GitHub repository, generates the necessary code, and prepares the changes for GitHub. For beginners, its main benefit is that they can request an outcome, such as adding a website tab, without manually writing or navigating all of the underlying code themselves.

Q: How can a nontechnical user modify a website with Codex?

A nontechnical user can connect Codex to the website's GitHub repository and enter a focused instruction describing the desired modification. Codex then searches the project files, determines what needs to change, generates the code, and reports the result. The user creates a pull request, checks its status, merges it, and verifies the deployed website after the update completes.

Q: What is a GitHub repository in the Codex workflow?

A GitHub repository is the project location that stores the website's code files and records its history. Each project, such as a personal or marketing site, can have its own repository. The user can make the repository public or private and add a README explaining its purpose. Codex connects to this repository so it can inspect and change the project.

Q: Why does Codex use branches and pull requests?

Branches allow Codex to work on a separate copy of the main codebase instead of changing the main branch immediately. After the requested feature is completed, a pull request presents the proposed changes for review. The user can inspect the summary, changed files, checks, and conflict status before merging the branch back into the main project.

Q: How do you publish a Codex-generated website change?

Finishing a Codex task does not automatically update the live website. The user first creates a new pull request from the completed task and reviews its summary and checks. If the pull request has passed the available checks and has no conflict with the base branch, the user merges it. The connected deployment service then publishes the updated main branch.

Q: Why should Codex prompts include every required behavior?

Codex may recognize related parts of a project without changing them when the request does not require those changes. During the demonstration, it found the existing keyboard event listeners but concluded that they needed no update. The example shows that users should explicitly request related behavior, such as adding a keyboard shortcut, rather than assuming Codex will include it automatically.

Q: What should beginners check before merging Codex changes?

Beginners should review Codex's explanation of what it changed, inspect the files or summary when useful, and check whether the pull request reports successful checks and no conflicts with the main branch. If a deployment preview is available through the connected service, it can provide another verification step. After merging, users should refresh the live site and confirm the requested result.

Q: What is a good first Codex project for a nontechnical user?

A simple personal website is presented as a suitable starting project because users can request small, visible changes and quickly understand whether they worked. The demonstrated task adds a food tab and a tacos entry to an existing site. Starting with focused website modifications also helps beginners learn repositories, branches, pull requests, merges, checks, and deployment gradually.

Summary & Key Takeaways

• Codex accepts a plain-language development task, examines the connected repository, identifies relevant files, writes the requested code, and reports what changed. In the demonstration, it adds a food tab and a tacos entry to a personal website, allowing a nontechnical user to direct the work without manually editing the underlying files.

• GitHub stores the project inside a repository and records updates as commits. Codex performs new work on a separate branch, after which the user creates a pull request. The pull request summarizes the changes, displays automated checks, identifies conflicts with the main branch, and provides the mechanism for merging successful work into the live project.

• The recommended beginner approach is to experiment with a simple personal website before attempting more complex applications. Users should give Codex focused instructions, review its stated changes, check previews and automated results when available, and verify the deployed website after merging. Codex can reduce direct code handling, but users still manage the development workflow.
