AI assistants for small-business marketing
Sintra AI review
Twelve ready-made AI "helpers" for marketing, social media and admin at one low price — but 250 credits a month are shared by everyone in the workspace, billing is upfront plus tax, and the refund promise is narrower in the terms.
Prices and terms checked against Sintra AI's own pages — sources.
Pick Sintra AI if…
- Solo founders and micro-businesses that want ready-made marketing, social and copy assistants without writing prompts
- People who prefer a guided assistant per task over a blank chatbot
Skip it if…
- Heavy users and teams — 250 credits are shared by everyone, and larger credit tiers have no public web price
- EU businesses that need EU-only hosting or a SOC 2 or ISO certificate — neither is offered
- Anyone who wants a low price without prepaying — the $15.60 rate is $187.20 paid upfront
Sintra AI packages twelve role-based assistants — for social media, email, SEO, customer support, sales and admin — behind one subscription, with a shared “Brain” that remembers your business details across all of them.
How we checked Sintra AI
Checked without an account on 20 October 2026: pricing page, US and EU terms, refund policy, data-processing agreement, privacy policy, the help centre, the App Store listing and the 44 most recent Trustpilot reviews. Sintra has no public demo and no public API documentation; the “free tools” on its site are landing pages without a working tool. Nothing below is a hands-on result.
| Checked | What we found |
|---|---|
| Pricing page vs. checkout | Prices are per month, but billed upfront: $70.80 a quarter, $187.20 a year, plus tax |
| Credits | 250 a month on every plan. A chat message costs 0.1–1 credit, an image 0.5–1.8, a 15-second video about 40 |
| More credits | Only as a recurring tier; web prices shown only inside the account. iOS: 500 credits for $124.99 a month |
| Trial | Not on the pricing page; help centre: 3 days with 50 credits, then a free plan with 20 credits a month |
| Refunds | Refund policy: full refund within 14 days “for any reason”. US terms §10.5.2: “no-refund policy, unless … faulty” |
| Price at renewal | “Renewals will be charged at then current rates” (§10.2.3); the help centre says discounts are kept while you stay subscribed |
| Data processing | DPA since March 2025, accepted by using the service; 22 named subprocessors incl. OpenAI and Anthropic; US or EU |
| Model training | Privacy policy: AI providers may not train on your personal data |
| Product activity | No dated changelog; 13 iOS releases between 22 July and 8 October 2026, 9 of them “stability fixes” |
| Status page | None found |
What it really costs
Web prices before tax, as of 20 October 2026. Sintra adds tax at checkout where it applies.
| Scenario | Plan | Paid upfront | Per month |
|---|---|---|---|
| Solo, about 5 chats a day | 12-month term | $187.20 | $15.60 |
| Solo, wants to cancel any month | Monthly | $48.50 | $48.50 ($582 a year) |
| 5 people in one workspace, text only | 12-month term | $187.20 | $15.60 — if 250 shared credits last |
| 5 people, separate workspaces | 5 × 12-month term | $936 | $78 |
Five people writing five short messages each working day use roughly the whole 250 credits on text alone; images or scheduled tasks use them up early in the month. Team seats are free, credits are not.
What users report
Trustpilot shows no score for Sintra: it suspended the rating for “a breach of our guidelines” and notes that the company “has been offering incentives for reviews” (checked 20 October 2026). Of the 44 most recent reviews, 31 give one star. The most frequent complaint is credits running out after the switch to a credit model, followed by refunds and cancelling, slow support and buggy integrations. Positive reviews mention time saved for solo owners. The iOS app has 4.6 out of 5 from 2,600 ratings.

How Sintra AI scores
2.9 / 5
- Value for money Weight 25% 3.5 / 5 $15.60 a month on a 12-month term is low for 12 assistants, but monthly billing is $48.50 and every plan gets the same 250 credits.
- Features for small businesses Weight 25% 3.5 / 5 12 role-based helpers with shared business memory and mobile apps; the integrations page names about 30, not the 1000+ on the homepage.
- Data protection (EU) Weight 20% 2.5 / 5 A DPA with 22 subprocessors and SCCs applies on use, and AI providers may not train on your data; no EU-only hosting, no SOC 2 or ISO.
- Try before you pay Weight 15% 2.5 / 5 A 3-day trial with 50 credits and a 14-day money-back guarantee exist, but the pricing page shows neither trial nor free plan.
- Fair terms Weight 15% 2.0 / 5 The terms (§10.5.2) only refund proven faults, narrower than the refund policy; billing is upfront and credits do not roll over.
The score weighs documented facts — prices, plan limits, terms and the vendor's data-processing documents as of 20 Oct 2026. It is not a lab test. How the score works.

Questions
Sintra AI: common questions
Does Sintra AI have a free trial?
The pricing page shows none, only a 14-day money-back guarantee. The help centre describes a one-time 3-day trial with 50 credits, and after cancelling you keep a free plan with 20 credits a month.
Can I get a refund from Sintra AI?
The refund policy promises a full refund on the first web purchase if you ask within 14 days; credit top-ups are never refunded. The US terms (§10.5.2) only refund proven faults, and EU customers get their 14-day withdrawal minus a pro-rata amount.
What happens when Sintra runs out of credits?
Unused credits do not roll over. The help centre says the helpers stop working until the monthly reset or a top-up; the terms (§18.6) say the service moves to lower-tier models.
Is my data used to train AI models at Sintra?
The privacy policy says Sintra does not let its AI providers train foundation models on your personal data. The terms allow Sintra to use de-identified, aggregated usage data.
