Sintra sells a set of 12+ pre-named AI helpers, each built for one job: Soshie posts and schedules social content, Cassie handles customer support replies, Penn writes copy, Dexter pulls and explains data, Emmie runs email campaigns, and so on. You chat with each helper directly and connect it to tools you already use, like Gmail, Google Calendar, Notion, Facebook, and Instagram.
Instead of paying per helper, you buy the whole bundle (called Sintra X) and get a shared pool of monthly credits that every helper draws from when it does an "advanced" AI action. Run out of credits and you either wait for the reset or buy more. You can also buy one helper on its own, but it costs more per month than the full bundle.
Sintra positions itself as a replacement for hiring several single-purpose freelancers or junior staff, not as infrastructure for building custom agents. There's no visual workflow builder or open API for wiring helpers into your own systems.

Who it's for
- ✓ Solo founders and small teams who want ready-made helpers for common marketing and support tasks without configuring anything
- ✓ Teams that already know which roles they need covered (social, email, support, SEO) and want one bill for all of them
- ✓ Non-technical operators who want to chat with an AI helper the way they'd brief a contractor, rather than build a workflow
Who should look elsewhere
- ✗ Teams that want to design custom multi-step agent workflows or connect to their own APIs
- ✗ Heavy users who will burn through 250 monthly credits fast and don't want to budget for top-ups
- ✗ Anyone who wants only one or two helpers cheaply, since a single helper costs more standalone than the full bundle
Pros
- + One flat bundle price covers all 12+ helpers instead of paying per role
- + Helpers are pre-built for specific business functions, so there's no setup or prompt engineering to get started
- + Prepaying for a year cuts the monthly rate to about a third of the pay-monthly price
- + 14-day money-back guarantee if it doesn't work out
Cons
- – Usage is capped by a shared 250-credit monthly pool across all helpers, and heavier use requires paid credit top-ups
- – No free plan, only a time-limited refund window
- – Buying a single helper standalone ($39/mo) costs more than the entire bundle on any prepay length, which pushes you toward buying more than you may need
- – No visual automation builder or open API for custom workflows, unlike more developer-oriented agent platforms
Sintra pricing
At about $15.6/month to start, it is one of the cheaper options in AI Employees.
| Plan | Price | Highlights |
|---|---|---|
| Sintra X - 1 month | $48.5/mo | All 12+ AI helpers (Cassie, Penn, Buddy, Dexter, Commet, Milli, Gigi, Scouty, Seomi, Soshie, Vizzy, Emmie) · 250 credits per month · 15+ integrations · Billed monthly, no long-term commitment |
| Sintra X - 3 month | $23.6/mo | Same helper bundle and 250 monthly credits · Paid upfront every 3 months |
| Sintra X - 12 month | $15.6/mo | Same helper bundle and 250 monthly credits · Paid upfront for the year · Sintra's marked "most popular" plan |
| Individual helper | $39/agent/mo | One AI helper only, no bundle · For teams that want a single role, not the full team |
Sintra sells one bundle (Sintra X) at three commitment lengths rather than feature tiers. The monthly rate drops the longer you prepay: $48.50/mo billed monthly, $23.60/mo billed every 3 months, $15.60/mo billed once a year. All three unlock the same 12+ helpers and the same 250 monthly credits; credits, not seats, are the real usage limit and Sintra sells extra credit top-ups separately. Buying a single named helper on its own costs $39/mo, more than the full 12-helper bundle at any prepay length. There's a 14-day money-back guarantee, not a free trial.

Sintra FAQ
Is Sintra free to use?+
No. There's no free forever plan. Sintra offers a 14-day money-back guarantee instead of a free trial, so you pay upfront and can ask for a refund within two weeks if it's not a fit.
How much does Sintra cost?+
The full Sintra X bundle of 12+ helpers starts at $48.50/month if you pay monthly, drops to $23.60/month paid quarterly, and drops to $15.60/month if you prepay for a year. Every plan includes the same 250 monthly credits.
What happens when I run out of credits?+
Each plan includes 250 credits a month that reset monthly. Advanced AI actions consume credits, and once you use them up you need to buy additional credit top-ups or wait for the next reset.
Can I buy just one AI helper instead of the whole bundle?+
Yes, a single named helper costs $39/month on its own, but that's more expensive per month than the full 12-helper bundle on any prepay length, so most buyers end up better off with the bundle.
