Card payment is handled by Stripe. Use the same email you sign in with — the checkout email must match your sign-in email for the plan to apply to your account. Excel downloads are never metered and never count against your 3 free messages. No rollover; fair-use caps only.

How the free taste works

Three real build-ups, no card, no catch

Sign in with a magic link and ask three questions. Each one comes back as the full first-principles build-up — labour, plant, equipment, materials, outputs, waste and the fee-on-fee ladder — with the editable Excel workbook to download. The three are yours forever, per email.

After your third: “That’s your 3 free messages — Starter is £10/month for 100.”

In every plan — free taste included
