Connect Vindex to Claude Desktop and claude.ai
Claude Desktop and claude.ai are where a lot of copy, replies, and documents get drafted. Connected to Vindex, the draft can be checked against your rules in the same conversation.
Three steps, about 2 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
Add Vindex as a custom connector
Open Settings and go to Connectors. Choose Add custom connector, name it Vindex, and paste the server URL. Save.
The connector belongs to your Claude account, so it follows you between the desktop app and claude.ai. On a Team or Enterprise plan an admin may need to allow custom connectors first.

Next to the new connector, choose Connect. A Vindex sign-in opens; use the account you use for the Vindex Portal, or create one on this screen to start on the free plan.
Back in Claude, the connector shows as connected. In a conversation, open the tools menu and make sure Vindex is enabled for that chat.
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.
Claude Desktop and claude.ai 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
Add custom connector is not available
On Team and Enterprise plans an owner has to allow custom connectors in the organization's settings. On Free plans custom connectors may not be offered; check the current plan comparison.
Claude says it cannot see a Vindex tool
Open the tools menu in the composer and enable Vindex for this conversation. Connectors are enabled per chat.
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.
