Can I start without installing anything?

Yes. Choose a starting question on this page and open it in ordinary ChatGPT or Claude. Sign-in may be required. It starts a conversation, not a plugin installation, and does not promise the illustrated interface.

What can I work through?

Start with a brand, website, content, or marketing decision. Explain what is happening, what you have tried, and what evidence you have. Ask for a possible explanation, what supports it, and one thing to check next.

When would I use the full plugin?

Use the installed plugin when you want a repeatable set of guided methods in a supported app. Codex and Claude Code setup options are below. Claude Code is a separate app from Claude in your browser.

The starting question and MIT-licensed skill package are free. Your chosen app and optional research services may have their own account requirements and charges. Human services from 8gnc are separate.

The 37-skill method stays intact. Compatible ChatGPT and Codex hosts can show what may be getting in the way, what to try first, and the evidence behind the answer in one read-only interface. You decide whether to use the advice, challenge it, or open a supplied output. Claude Code remains skills-only.

What data reaches the renderer?

Only the structured fields the host submits for the Working Diagnosis: the problem summary, evidence statements and provenance, as-of dates, the primary constraint, cited inferences, unknowns, route, confidence, and human decision gate.

Does the renderer verify that the diagnosis is true?

No. It checks structure, dates, and internal evidence references. It does not browse a source, contact anyone, generate research, or certify a recommendation.

Can 8gnc access our CRM, email, or private systems?

The renderer cannot. It has no CRM, mailbox, approval system, client portal, database, or private-system connection. Host-side skills can use only the evidence and capabilities you deliberately provide to that host.

Can it publish, send, purchase, deploy, or change anything?

No. The renderer is read-only. An output or conversational approval is not authorization for an external action.

Is an 8gnc account required?

No. The renderer has no account connection or authentication. Your host application and any optional third-party research service may have separate account requirements.

Do Codex and Claude Code remain supported?

Yes. Codex supports the 37 skills plus the renderer connection. Claude Code installs the same 37 skills without the hosted renderer.

Find what's holding your business back—and what to try next.

People show interest but don't get in touch. Or another marketing idea leaves you wondering what to do first. Start with the question in front of you. 8gnc helps you work through it in the chat you already use.

Start with a question in:

Open in ChatGPT Open in Claude

Opens in the app you choose; sign-in may be required. This starts a conversation, not a plugin installation.

Question missing?

Here is the exact prompt.

Help me work out what is getting in the way of my business and what to try next. Ask me first what is happening, who I am trying to reach, and what I have already tried. Then ask one question at a time, only when the answer would change your advice. Use the information I provide; do not invent facts, results or customer opinions. Separate what we know from what you are assuming. When there is enough information, explain the most likely problem in plain language, why you think that, and one practical next step. Tell me what evidence would change your view. If there is not enough information, say what is missing. Do not assume I need a new logo, a website, ads or an agency. Help me make progress on my own.

Open your chat, paste the prompt, and decide when to send it.

Work through a question.

Start with a guided question in ChatGPT or Claude. Explain what is happening and ask for a possible explanation, what supports it, and one thing to check next. You can do this without a call with us.

Choose the problem closest to yours. Open it in ChatGPT or Claude, then answer the questions about your business. Ask for one next step and why it makes sense.

Choose a starting point if one fits.

What to change on the homepage first.

In this example, the recommendation is to test one clear starting point instead of three choices before adding more traffic. The homepage map sets out what belongs before the first button, what follows it, which evidence to keep, and which work should wait.

The example starts with a homepage that creates interest but leaves buyers unsure what to do next. Its evidence is demonstration data, not a client result.

Use the plugin in a supported app.

The 8gnc plugin adds a set of guided methods to a supported app. It needs installation. Check the app and setup steps before choosing it.

ChatGPT comes first. The current listing is v0.2.1; the v0.3 interface update is coming soon. Codex and Claude Code use the install commands below. Claude Code is not Claude in your browser. Your app may require an account or a paid plan; installing the MIT-licensed skills is free.

Account and research requirements.

The renderer requires no 8gnc account, authentication, database, or private-system connection. Your host and any optional research service may have separate requirements.

Optional host-side research ↗: Some specialist methods can use a research service you configure in the host. The 8gnc renderer never calls DataForSEO or another external source and requires no paid account.

You still decide what to do.

The renderer presents the structured diagnosis supplied by the host. It does not create or verify the diagnosis, research, fetch, store, access private systems, or execute recommendations.

“Use this route” continues with the proposed method inside the host. “Challenge it” asks the host to pressure-test the diagnosis. Neither button executes an external action.

If the evidence is not there, 8gnc does not force a diagnosis. It stops, names what is missing, and asks for the source needed to continue.
