| The gate | ||||
| Spaces One space, kept apart from every other. Your own business, one client, one property. A check reads one space and never spans them, so a personal fact cannot surface in client work. A space holds subspaces, the way a folder holds folders, so a client can hold a subspace per matter. | 1, plus 1 subspace | Unlimited, with subspaces | Unlimited, with subspaces | Unlimited, with subspaces |
| Rules A limit your writing has to obey, with a number in it. No em dashes, under 1300 characters, never these words. Datum measures them rather than asking the AI nicely. | 3 | Unlimited | Unlimited | Unlimited |
| Skills How you do a recurring task, written once and reachable from every assistant on every device. No pasted copy that quietly goes out of date. | 1 | – | Unlimited | Unlimited |
| Material The raw thing you work from: a brand guide, a transcript, notes off a call. Never capped, because what you keep to write from is not what anybody should be rationed on. | Unlimited | Unlimited | Unlimited | Unlimited |
| Sources Where one kind of thing actually lives: a contract, a rate sheet, a page in Notion. Datum records the location and never reads it. When a fact is stale or missing, your assistant gets told where to go and look instead of guessing. | 1 | Unlimited | Unlimited | Unlimited |
| Vault Keeps the exact records behind every receipt, addressed by hash. A year later you can produce what a report was checked against, and prove it’s the same bytes. | – | – | ✓ | ✓ |
| Your content is never read by us On paid plans, nobody at Riley AI Systems reads what you confirm or what you write. On the free plan, what you put in may be used to improve Datum, as the privacy policy sets out. | – | ✓ | ✓ | ✓ |
| People | ||||
| People with access Everyone who can draft against your confirmed facts and your rules, counting you. Anybody but you cannot change either one, and you can revoke them instantly. | 1 | 1 | 2 | 5 |
| Writers cannot change your rules A writer is gated by the rules you confirmed. They can draft and get refused; deciding what is true about the business stays with you. | – | – | ✓ | ✓ |
| Every confirmation names who made it Every confirmed fact records who vouched for it and whether they answered for themselves or on somebody’s behalf. Six months later you can tell which. | ✓ | ✓ | ✓ | ✓ |
| Never capped, on any plan | ||||
| Checks Never capped, on any plan. A gate you are rationed on is a gate you learn to route around. | Unlimited | Unlimited | Unlimited | Unlimited |
| Receipts A signed, tamper evident record of what was checked and how it came out. Never capped. | Unlimited | Unlimited | Unlimited | Unlimited |
| Signed, and can’t be changed afterwards Every receipt is signed when the check runs, so nobody can edit it later, including us. If anyone ever asks, it can be checked against a public key. | ✓ | ✓ | ✓ | ✓ |
| Export everything, any time Facts, rules, skills and the whole receipt chain, in one call. The account is yours and this is what that means in practice. | ✓ | ✓ | ✓ | ✓ |
More than five people on one account, or anything needing single sign-on, an SLA or a signed data agreement.
