Subi vs Stay AI
Stay AI sells one plan, priced for brands that have already committed to subscriptions and want the retention tooling built around them. Subi starts lower and steps up. Which matters more depends on where you are.
The short version
At every volume in the table below, on the plan that fits, Subi is cheaper by $400 or more.
Stay AI does not state a free trial on its pricing page. We give 7 days plus a 3-month money-back guarantee.
Stay AI publishes a single Pro plan at $499/mo plus 1% plus 19c per subscription order.
What you would actually pay
Monthly cost at different volumes of subscription revenue processed. Subi figures from our own billing configuration; Stay AI figures from their public pricing page. Their 19c per-order fee is not included, so their real figure is a little higher than shown. Both checked 1 September 2026.
| Monthly subscription revenue | Subi (best-fit plan) | Stay AI (Pro) |

| $50,000 | $519 on Subi | $999 |
| $100,000 | $879 on Subi Plus | $1,499 |
Where Stay AI is the better choice
We would rather you pick correctly than pick us.
- →You are already at high subscription volume and want retention-specific tooling purpose-built for reducing subscriber churn. Stay AI's pitch is the churn-prevention stack, and for a brand at that size it is a coherent one.
- →You want a vendor whose entire book is subscription retention, and you value that focus over a broader toolset.
- →You have unusual requirements and want custom terms. That is what their Enterprise tier is for.
Where Subi is the better choice
The cases where the table above and the terms both point our way.
- ✓You are not yet at the volume where a $499 floor makes sense, and you would rather your subscription app cost scale with your subscription revenue.
- ✓You want to try before you commit. Stay AI's pricing page states no free trial; ours is 7 days with a 3-month money-back guarantee behind it.
- ✓You want subscriptions, memberships and bundles from one app without an enterprise contract conversation to get started.
If you do decide to move
Subscription migration is not a CSV import. Existing contracts have to keep billing on their own schedules, with their own discounts, without asking your customers to re-enter anything.
Talk to us first with your numbers. We will tell you which plan fits and what it will cost.
We map your existing plans, discounts and billing dates before anything moves.
Contracts transfer with their schedules intact, subscribers do not re-subscribe and do not re-enter payment details.
We stay on it through the first billing cycle, which is the one where problems actually surface.
Questions merchants ask
Will my subscribers have to sign up again?
No. Contracts move with their existing billing dates and discounts. Asking subscribers to re-enter payment details is how a migration loses customers, so the process is built to avoid it.
Is Subi cheaper than Stay AI?
At every volume in the table above, yes, and by a wide margin. Stay AI's published floor is $499 a month before any transaction fee. In absolute dollars the difference ranges from about $410 to $620 a month across the volumes we checked.
Does Stay AI offer a free trial?
Their pricing page does not state one as of 1 September 2026. We would rather you check that yourself than take our word for it, pricing pages change.
