chatgpt.com Browser Setup

Unzip the CCOS file and find the skills folder

Download the CCOS ZIP and fully extract it. For this setup we’re going into the skills folder. Inside you’ll see subfolders for each plugin — and inside each subfolder are the individual skill ZIP files.

• On Windows: right-click the ZIP and choose “Extract All” — don’t just double-click the ZIP
• On Mac: double-clicking the ZIP creates an extracted folder next to it
• You won’t need the plugin-zips or marketplace folders — those are for other setups
• Keep the skills folder somewhere easy to find

Stop here and make sure this is actually the right setup

Before you keep going, make sure you really want the browser route. This page is for lightweight, single-conversation use. If you want CCOS to work across files, persistent context, and connected workflows, the browser will feel limited fast.

• Best browser use case: one-off copy, brainstorming, light audits, and simple self-contained skills
• Bad browser use case: file-heavy projects, multi-step builds, or anything that should persist cleanly between tasks
• If that second list sounds like you, switch to Codex Desktop before you go further

Check which ChatGPT plan you’re on

How much of this guide applies depends on your plan. ChatGPT Business has native skills support. Most other plans do not, which means you are working with a temporary file-attachment workaround rather than a true installed skill experience.

• If you’re on a Business plan: follow Steps 4–6 below for native skill install
• If you’re on Plus, Pro, or Free: skip to Step 7 for the limited attach-and-go method
• Not sure which plan you have? Go to chatgpt.com/settings — your plan is listed under Subscription

Business plan: Open the Skills settings page

If you’re on a ChatGPT Business plan, go to your account settings and find the Skills section. This is where you can upload individual CCOS skill ZIP files.

Business plan: Upload a skill ZIP

Click the option to add a new skill, then upload one of the skill ZIP files from your skills folder. Each skill is installed individually.

• Start with the cc-help skill — it will guide you on what to add next
• The cc-create-dna skill is the recommended second install — most skills rely on your Creator DNA context
• Even on Business, browser ChatGPT is still better for lighter tasks than for true project-based CCOS work

Business plan: Use a skill in any chat

Once installed, you can use a skill by name in any ChatGPT conversation.

All plans: Attach a skill ZIP to any conversation

If you don’t have native skills support, you can still sometimes get useful results by attaching a skill ZIP file directly to a ChatGPT conversation and asking it to use the skill. Treat this as a lightweight workaround, not a full installation path.

• Open any ChatGPT conversation
• Click the attachment icon (paperclip) and select a skill ZIP file from your skills folder
• Send the message below along with the attached file
• If the result feels incomplete or fragile, that is a sign to move to desktop rather than forcing the browser route

Start with cc-help, then cc-create-dna

If you stay in the browser, start with cc-help — it will orient you and recommend your next step. After that, run cc-create-dna to set up your Creator DNA context files. Just know that browser ChatGPT will not handle this context as cleanly or reliably as the desktop setups.

What chatgpt.com is actually good for

If you insist on staying in browser ChatGPT, keep your expectations narrow. It can still be genuinely useful when the task is small and self-contained.

• Brainstorming, copywriting, and idea generation
• Single-purpose skills that produce a self-contained output
• Quick experiments before you decide to move the task into a real project workspace
• Short sessions where you do not mind manually saving, copying, and moving files yourself
