The helpers share a knowledge base about the business called Brain AI and connect to tools such as Gmail, Google Calendar, Facebook and Notion to carry out tasks. It runs on the web and in iOS and Android apps, and is sold on 1-, 3- and 12-month plans with no free tier.

The report card
Best for a ready-made set of helpers for a small business
Sintra hands a small business 12 ready-made AI helpers, for social posts, customer support, SEO and more, all drawing on one shared store of what they know about your brand. There's no free plan and no trial, only a 14-day money-back guarantee, and the list price starts at $52 a month on a 12-month term paid in one go. You can't build your own agent, no API is on record, and advanced actions come out of 250 credits a month.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | List prices run from $52 a month on the 12-month plan to $97 for a single month. Agent tools here sit at $21.25 in the middle and the dearest tenth starts at $50, so Sintra opens above that line. The site had it on sale at $15.60 and $48.50 when checked, but a standing sale isn't a price. |
| Free plan and trial | F | Nothing is free. The site advertises no free plan and no trial, so step one is paying. Every plan carries a 14-day money-back guarantee, which is a safety net, not a trial. |
| Features | C | Twelve helpers with set jobs and one Brain AI that knows your business, and they'll send Gmail, add calendar events and post to Facebook, Instagram and LinkedIn. That's the basics covered. But you can't build an agent of your own, there's no API on record, and advanced actions come out of 250 credits a month. |
| Ease of use | B | 4.6 from about 2,500 App Store ratings, under the 4.7 that would make it an A. The helpers arrive ready-made, so you pick one and start typing rather than wiring anything up, and the one-click use cases cover jobs like keyword research and email campaigns. |
| Platforms and integrations | B | Web, iPhone and Android, with connections to Gmail, Outlook, Google Calendar, Facebook, Instagram, LinkedIn, Notion and QuickBooks. No desktop app and no API are listed, and that's what keeps it off an A. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Sintra is for
- Fits if you run a small business alone and need a hand with social posts, emails and SEO copy
- Works for writing in other languages, as the helpers work in more than 100
Who it is not for
- Not for you if you want to try before you pay, as there's no free plan or trial
- Pricey if you pay a month at a time, at a $97 list price against $52 on the 12-month plan
- Tight if you lean on advanced actions, with 250 credits a month before top-ups
- Watch out: the 3-month and 12-month rates are charged as one payment for the whole term
- Watch out: the site showed plans at 50% to 70% off list when checked, and its FAQ quotes $48.50 as the start

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Sintra you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 47 of the 51 other AI agents grade higher. It costs $624 a year.
What you could not
- An AI agent, with the models and the safeguards behind it.
- An AI model, which you can rent by the request but not make.
- Email sent in volume that still reaches the inbox.
- Connections to other products, each kept working as those products change.
- A real app for iOS and Android. Something home-made would be a web page.
- What a company asks for before it lets staff use something: roles and permissions.
- Sharing with other people, which means accounts and invitations.
What this rests on. Sintra’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
