Sintra AI review12 role-based AI helpers for marketing, sales and support, sharing one business memory
Good
Brent score, out of 5
Sintra packages 12 ready-made AI assistants, each with a job such as social media, email, SEO, copywriting or support, around one shared memory of your business. It is easy for a solo owner to get going and costs as little as $15.60 a month on a yearly plan. Every plan includes the same 250 monthly credits for advanced actions, top-up prices are not public, and recent Trustpilot reviews complain about the move to credits and refunds after the 14-day window, so start with a short plan.

You know you should post on social media every day, send a newsletter, answer customer emails faster and write blog posts for SEO. But you are one person, and hiring a marketer, a copywriter and a support agent is not in the budget.
Sintra AI offers a team of 12 AI helpers instead, each set up for one job: Soshie for social media, Emmie for email, Seomi for SEO, Penn for copy, Cassie for support and more. They share one memory of your business, so you explain your brand once rather than in every chat.
This review covers what each helper does, how the credit system works, what the plans really cost and what customers complain about, so you can decide if it is worth a paid month.
What is Sintra AI?
Sintra AI, from PlayOS, Inc., is a subscription platform of role-based AI assistants for small businesses. Each helper is a chatbot tuned for a role, with one-click use cases for common tasks. A shared knowledge base called Brain AI stores your business details, brand voice, files and goals and feeds them to every helper. Helpers can connect to tools such as email, calendars, social platforms, CRMs and Notion. Sintra says its Sintra X tier is built on Claude 4.5 Sonnet. Plans include 250 credits a month for advanced AI actions, with paid top-ups when you run out.
