The question everyone asks

Why not just use ChatGPT or Claude?

Because a chatbot has never seen your business. Greymill has. Same question, typed into both.

You type

“How is my cash looking next month?”

✗ Can’t see your books, your inbox or your contracts. Asks you to type it all in.

How it works

Brief the team once. Ask anything after that.

No forms, no briefs, no booking. You talk to Greymill the way you would talk to a colleague who already knows your business.

Tell them about your business, once

Your industry, where you operate, the size of the team and what matters right now. Everything the sixteen specialists produce from then on is framed for your business, not a generic one.

        Questions

        Fair questions, straight answers.

        Is my business data used to train AI models?+
        No. Your business stays your business. Nothing you share is used to train AI: your conversations belong to your workspace and they are not visible to other customers. Connections only read your data, apart from emails you approve and choose to save or send from your own inbox, and you can switch them off any time. No ads, no cut of your sales. One monthly fee. Greymill Limited is registered with the UK Information Commission’s Office and the full detail is in the privacy policy and on the security page.
        Does Greymill replace my accountant, solicitor or other professional advisers?+
        No. Greymill gives you a whole team to think with every day: the numbers modelled, the contract read, the campaign planned, the hire prepared, the filing checklist ready, all before you speak to anyone by the hour. What Greymill produces is software output from the information you give it, so Greymill takes no instruction, owes no professional duty and files nothing unless you send it yourself. Where a matter needs a regulated professional to sign it off, Greymill says so and tells you exactly what to take to them. Customers arrive at their accountant or lawyer with the work done and the questions sharp, which is usually the cheapest hour they will ever buy.
        How is the savings figure calculated?+
        Two numbers, multiplied. First, how long the work would have taken you: from 2 minutes for a one-line answer up to 22 for a full document, and never more however long the answer is. Second, what that kind of work typically costs to buy in where you are. It is an estimate, and we count low on purpose, so the figure should sit below what the work would really have cost you. The full method is published, and every Monday email links to it.
        What happens after the 7-day trial?+
        Your trial runs on the Scale plan so you see everything. If you do nothing, it simply ends. You are only charged if you choose a plan, and you can cancel any plan at any time from your account in two clicks.
        Do the specialists understand my country and industry?+
        Yes. Greymill holds 2.5 million words of researched industry knowledge across more than forty sectors, from construction to ecommerce. UK and US rules are written separately, each with its own law, tax and hiring rules, and each country's half is over 350,000 words as of Oct 2026. Tell any specialist what you do and where, and the answer fits your business. Greymill works anywhere; the UK and US are covered in the most depth. Prices show in your own currency, and checkout adds your local tax.
        How do I cancel?+
        From your account settings, in two clicks, at any time. There are no lock-ins and no minimum term. Annual plans are refundable in line with the refund policy.

        Partners and referrals

        Two ways to share Greymill.

        Partners are paid in cash. Customers earn credit on their own bill.

        Paid in cash

        Partner programme

        For franchise head offices, trade associations and business networks, coaches and consultants, and IT, web and marketing agencies who introduce clients to Greymill.

        1. 1Apply, then share your own link
        2. 2A client signs up through it and is still paying 60 days later
        3. 3You are paid 30% of their plan, once

        How it adds up:

        • Introduce 1 client30% of their monthly plan, once
        • Introduce 10 clientsThe same for each, no quotas
        • How you are paidBank transfer, on the 1st or 15th

        Paid once: 30% of the client’s monthly plan price, and only after 60 days, so a monthly client who cancels, or any client refunded, before then earns nothing.

        Your own partner dashboard shows every click on your link, every sign-up and every payment, as it happens.

        Become a partner Already a partner? Partner login

        30% of the client’s monthly plan price, paid once 60 days after their first payment (annual plans are paid up front, so they qualify unless refunded). If they move to a cheaper plan before day 60, it is worked out on that plan; an upgrade keeps the plan they started on. Full terms in the Partner Agreement.
