Comparison

Axioma Facere vs. Sintra

Two answers to the same open roles. Sintra sells twelve named helpers on a credit meter; we sell ten governed roles on your own keys. The comparison, with dates — and with hiring in the first column, because that is the alternative both products are actually up against.

Every Sintra figure on this page was checked against public sources in August 2026. This category reprices constantly — trust their pricing page over any comparison, including this one.

Four questions

The differences that matter here are not features; they are what happens at the edges. These four questions find the edges. Our answers are below each one; ask the vendor for theirs.

What happens when the AI is asked to do something irreversible?

It parks. Anything irreversible stops at you at every trust level, and the escalation gate is human-only at the API — a roster call against it is refused, including a name escalating its own case.

Where is the record of when its permissions were widened, and why?

The trust ledger: append-only, a written reason on every change, including the changes that reduce your oversight.

What did last month’s credits or hours actually buy?

There are no credits or hours here. On your own keys the meter is your provider’s invoice, checkable line by line against the per-call ledger in your panel, and we keep $0 of usage; on keys we carry for you, the markup is a disclosed 10%, broken out on every ledger line.

Who can stop it — and is that enforced in software, or written in a policy?

You. The constraints are refusals, not warnings — enforced by the server — and a dead credential stands the whole company down. The failure mode is stillness.

The read

Where Sintra is strong, and where the record runs out.

Concede first: Sintra is the category’s biggest consumer brand for good reasons — polished onboarding, a genuinely low floor for non-technical users, and multi-language support. For a solo founder wanting light drafting help across many hats, it is a reasonable buy.

The differences are the meter and the record. Every Sintra plan carries the same 250-credit monthly cap, and credits do not roll over — so the question a working month raises is what those credits bought. Oversight is a per-task draft-or-execute choice: real, but binary and unrecorded. There is no graded trust to earn, and no ledger saying what a helper was permitted or when that widened.

One dated fact belongs on the record, stated neutrally: in 2026, Trustpilot suspended Sintra’s TrustScore over review incentives. A suspended score is meaningless in both directions, so we cite the suspension and no rating — and our own policy is zero incentives for reviews, stated publicly.

The roles differ too: Sintra’s helpers cluster on marketing and admin. Our roster reaches the books, financial planning, procurement, infrastructure, and security audit — the roles that make a back office a back office.
