How agencies keep each client's AI rules separate

The problem

You ask an AI tool to rewrite a client's pricing page. The draft sounds like another client. Now you must check every phrase, price and promise before you can judge the writing. Using several tools makes it harder to spot where the mix-up began.

You also keep explaining the same agency standards. A new editor needs the latest voice notes, the right files and a clear task. Copying an old brief feels convenient, but it can bring another client's words into the work. You need a clearer starting point for each client.

How onemind helps

A Mind holds your team's shared rules for AI tools, such as checking facts and asking about missing information. A Project is a folder of work, like one client or one product. Keep general agency habits in a shared Mind and each client's voice in their own Project Mind. You review proposed rule changes after Safe Check, an automatic check, before you approve them.

What it can save

Finding client details in the wrong place and fixing them takes time from your team's work. Say 4 people each lose about 20 minutes a week on these checks and fixes. That is about 6 hours a month, worth about US$350 at US$60 an hour.

4 people × 20 minutes ÷ 60 × 52 ÷ 12 ≈ 6 hours a month.

This is an example estimate, not a measured result. Use your own team's numbers. Try them in Solutions on the onemind homepage.

You still need to read results, so some time shifts to a quicker check rather than disappearing.

An example

This is a made-up example to show how it works, not a real customer.

1. You prepare two Projects: Client A website and Client B app. Client A's folder holds the website, content/pricing.md and brand/voice.md. Its Client A voice Mind asks for direct, restrained writing and approved product names. Client B has different files and voice rules.

2. You keep an Agency basics Mind for shared working habits. It asks tools to use supplied facts, flag gaps, write clear accessible text and leave client-facing changes for human review. It contains no private client briefs, offers or account details. A freelancer works only on Client A; you check their access separately.

3. Connect Codex, Claude Code and Cursor to Client A’s folder. Your editor checks that Claude Code shows Delivered for the agency and Client A rules. They open a new chat in the Client A website folder. You ask them to rewrite content/pricing.md, keep the existing prices and explain each plan. They must flag anything the files do not explain.

4. Claude Code drafts the changes. Your editor compares them with the price table, features and voice notes. A missing trial condition should become a question, not an invented offer. They also check for Client B's wording. Teammates see local file changes only after the owner shares a copy; later edits need another share.

5. Your reviewer reads the changed file and asks you about the trial condition. They also notice that Client A's rules do not say whether to call an account a workspace. Your editor proposes that clarification for Client A's Mind. Safe Check checks it, then you read and approve the wording.

6. Once Codex shows Delivered for the new Client A rules, the next editor starts a new chat for another page. They check whether it uses the agreed word. Client B's Mind and the shared agency Mind keep their own rules. The new page still needs its own facts and review.

How to know it worked

• Client A's new wording shows as approved in onemind.
• Each tool you use shows Delivered for the right client rules.
• In a new chat, the tool uses Client A's words and keeps the supplied prices.
• You read the changed file before you accept the copy.

What onemind doesn't do yet

• Separate Projects do not guarantee who can access client information. Check membership, file sharing and what people put in prompts.
• Delivered does not guarantee that every rule was followed. An open chat may keep older rules. onemind does not replace your own review.
• Automatic learning from finished tasks is coming. Fixing a draft today does not change a Mind; you still propose and approve rule changes.
