Connect Vindex to ChatGPT
ChatGPT drafts a lot of what ends up in front of customers. Connected to Vindex, it can read your rules and check a draft against them before you use it.
Three steps, about 3 minutes. Open to every registered Vindex user; new users create an account during sign-in, and a new account includes 100 free critique credits.
The walkthrough
Create the Vindex connector
In ChatGPT, open Settings, then Connectors. Under Advanced, turn on Developer mode, then choose Create. Name the connector Vindex, paste the server URL, and leave authentication on OAuth.
Connectors are a paid-plan feature; check the current plan comparison if the option is missing. Workspace admins on Team and Enterprise plans can publish the connector to everyone once.

When you save the connector, ChatGPT opens the Vindex sign-in. Use the account you use for the Vindex Portal; new users create one here and start on the free plan.
Afterwards the connector is listed as connected. In a chat, open the plus menu, choose Developer mode, and select Vindex so its tools are available in that conversation.
Run your first critique
Ask your agent to list your rules, then to check a draft against one. Reading your rules is free, and each critique uses one critique credit.
The result comes back in the chat: pass or fail for each rule, with the failing passage quoted.
List my Vindex rules.Check this draft with Vindex against the "Email tone" rule: <paste the draft>What comes back
Each rule gets a pass or fail, and a failure quotes the passage that broke the rule. A rule set also returns one overall result and the names of the rules that failed. The result carries the attempt number and your credits left.
ChatGPT does not block anything on its own. It gets the result and decides what to do next: usually, rewrite the quoted passage and run the critique again. Critique results and the loop has every field.
Troubleshooting
Developer mode or Create is missing
Custom MCP connectors need a paid plan and, on Team and Enterprise, a workspace admin to allow them. Check Settings, then Connectors, then Advanced for the Developer mode toggle.
ChatGPT answers without calling Vindex
Select Vindex from the plus menu in the conversation first. Connectors are opt-in per chat, and saying 'with Vindex' in the request helps the model pick the tool.
The agent answered without running a critique
Ask for it in the request: say "check it with Vindex". Put the standing instruction in your client's instructions file so it applies on every task. An agent chooses whether to call a tool, so treat an output as checked only when a result came back.
A critique came back as one sentence with no pass or fail
That sentence is a refusal or an error, such as no credits left, a rule that is not active, or a timeout. Ask your agent to check your credit balance, or try again in a moment.

Scoring user stories too?
The same connection and the same sign-in also score a story against INVEST. That is part of Integrated Vindex.
