ISMS CopilotISMS Copilot vs ChatGPT for compliance
Use both. Keep ChatGPT for general writing and analysis, and use ISMS Copilot as the GRC specialist for ISO 27001 policies, risk assessments, Statements of Applicability, and audit prep. Connect ISMS Copilot to ChatGPT as a custom MCP app, and ChatGPT can consult the specialist.
TL;DR
| Aspect | ChatGPT + ISMS Copilot | ChatGPT alone |
|---|---|---|
| Who does what | ChatGPT for general work; ISMS Copilot for the compliance project | One general assistant does everything |
| ISO 27001 knowledge | Version-aware, structured answers from the specialist | General knowledge; can mix versions or invent control numbers |
| Policy drafts | Audit-shaped and Annex A aligned | Good text you restructure for the audit |
| How they connect | ChatGPT connects to ISMS Copilot over MCP (custom app, sign-in); Codex too | Nothing to connect |
| Auditor acceptance | A draft you still own, review, and sign | Same rule: auditors do not accept a chatbot dump |
| Data handling | Compliance work can stay in ISMS Copilot: EU-hosted option with Advanced Data Protection on (AI only on Mistral AI in Frankfurt); we do not train on your chats | Consumer ChatGPT may retain and train unless you opt out. ChatGPT Business states no training on workspace data by default. |
| Price | Your ChatGPT plan, plus one ISMS Copilot plan: teammates free up to 50, shared usage pool | ChatGPT Plus is $20/person. ChatGPT Business Standard seats are $20/seat/month billed annually, 2-seat minimum (observed 2026-08-29). |
Keep the ISMS in the specialist workspace
Consumer ChatGPT can retain chats and use them for training unless you opt out. ChatGPT Business, the seat plan in the price table below, states that OpenAI does not train on workspace data by default. Confirm the plan you actually use. ISMS Copilot is the specialist workspace for policies, evidence, and audit-shaped drafts, next to the ChatGPT you already use.
When to use each
ChatGPT is strong at general tasks: writing emails, brainstorming, analysis, coding. For compliance work where structure and auditability matter, use the specialist workspace. ISMS Copilot is built around ISO 27001 clauses, Annex A controls, and how they map to other frameworks. Advanced Data Protection is optional and off by default.
Why EU data sovereignty matters →Use both today
ChatGPT can call ISMS Copilot directly. In ChatGPT, add a custom MCP app with the ISMS Copilot server URL, choose OAuth and keep the default settings, then sign in to ISMS Copilot and click Approve. ChatGPT can then read your workspaces, company profile and memories, and ask the specialist. You can also keep the two open side by side. If you use Codex, OpenAI's coding agent, connect it to the ISMS Copilot MCP server with a personal access token so it can hand compliance steps to the specialist. Developers can also call the ISMS Copilot Model API from their own code.
ISMS Copilot for agents →What a team pays for ChatGPT vs ISMS Copilot
USD list, pretax, United States. Observed 2026-08-29. Prices move. Our checkout and the vendor pages win if this drifts.
One person, monthly list
| Meter | ISMS Copilot Plus | ChatGPT Plus |
|---|---|---|
| Monthly list | $29 | $20 |
Cost to give N people access, prepaid annual
Their workspace minimum is 2 paid seats.
| People | ISMS Copilot Plus | ISMS Copilot Standard | ChatGPT Business, Standard seat | ChatGPT Business, Premium seat |
|---|---|---|---|---|
| 2 | $290 | $490 | $480 | $2,400 |
| 5 | $290 | $490 | $1,200 | $6,000 |
| 10 | $290 | $490 | $2,400 | $12,000 |
| 25 | $290 | $490 | $6,000 | $30,000 |
This is the cost to give N people access, not equivalent throughput. On ISMS Copilot those people share one plan's 4-hour credit pool (Plus 60 credits, Standard 125) and pause at the cap. Each ChatGPT Business Standard seat has its own included usage.
When the team's allowance runs out, the pause is the hard stop until it resets. The owner can buy extra usage or upgrade the plan to raise the pool.
ChatGPT Business Standard seats include a usage bucket, then optional workspace credits.

More than the model
Picking a compliance tool is not only a model choice. Workflow, framework depth by clause, audit-shaped output formats, sectoral coverage, and EU storage on AWS Frankfurt plus Advanced Data Protection for AI processing on Mistral AI in the EU are what turn AI capability into finished compliance work. Those are product decisions, not model upgrades.
Frequently Asked Questions
Can I use ChatGPT and ISMS Copilot together?
Yes, and most teams should. Use ChatGPT for general work. Use ISMS Copilot for the compliance project. Connect ISMS Copilot to ChatGPT as a custom MCP app (sign in with OAuth), run them side by side, or connect ISMS Copilot to Codex over MCP.
Can't I just use ChatGPT for ISO 27001?
You can, but you should not treat the output as audit-ready. The results need significant expert review and editing. ISMS Copilot produces structured, audit-shaped drafts that cut that rework.
Is ISMS Copilot more expensive than ChatGPT?
For one person, Plus is $29/month, $9 above ChatGPT Plus's $20/month list (observed 2026-08-29). For a team, ChatGPT Business sells Standard seats from $20/seat/month billed annually (2-seat minimum). ISMS Copilot sells one plan; teammates are free up to 50 and share one usage pool. That is cost of access, not equivalent throughput. See the table on this page.
Will my auditor accept an AI-drafted Statement of Applicability?
No. Auditors accept an SoA that your organization owns and can explain. An AI draft is a starting point. You review, tailor, and sign it.
Does ChatGPT know ISO 27001:2022 Annex A?
In a general way. It can mix versions, invent control numbers, and skip required fields. A specialist assistant is built to stay on the current control set.
Is ChatGPT safe for ISMS evidence and risk registers?
It depends on the plan. Consumer ChatGPT can retain chats and use them for training unless you opt out. ChatGPT Business states OpenAI does not train on workspace data by default. Enterprise and Edu data residency is a separate OpenAI option. Confirm the plan you actually use.
When is ChatGPT the right tool?
For general writing, brainstorming, analysis, and work that will not go to an auditor. Keep the ISMS, the SoA, and client evidence in the specialist workspace.
What is the best AI for ISO 27001?
A specialist assistant grounded in the standard, used next to the general AI you already have. See the dedicated comparison if you want the category answer.
