Sintra AI: 12 AI Emplyees to Automate Your Business in 2026
Sintra AI is a business automation platform that offers a complete team of 12 artificial intelligence assistants or ‘helpers’, each specialising in a different area. The tool falls under the AI agents and business automation category, positioning itself as a comprehensive solution for small and medium-sized businesses looking to delegate repetitive tasks without hiring additional staff.
For SMEs, tools like this represent an opportunity to compete on equal footing with larger companies, a small team simply can’t dedicate hours every day to managing social media, analysing data, and handling customer service all at once. Sintra AI addresses this challenge by offering virtual specialists that work 24/7 at a fraction of the cost of a traditional employee.
AgentAya Verdict
This tool was designed specifically for entrepreneurs and small business owners who need operational support without technical complexity. Its greatest strength lies in its Brain AI system, which enables the assistants to learn about your brand and maintain consistency across all interactions. This feature solves one of the most common problems with generic AI tools: the lack of context and personalisation. However, it does have some limitations for businesses that require highly customised workflows or integrations with complex enterprise systems.
Our recommendation is clear: if you’re an SME owner or entrepreneur looking to automate tasks without investing in a large team, or complex tools, Sintra AI is definitely worth a try. The 14-day money-back guarantee lets you evaluate whether it fits your actual needs before committing.

What sets Sintra AI apart from standard software is its contextualisation capability through Brain AI. While generic tools like ChatGPT require you to explain your business in every conversation, Sintra maintains persistent memory that enables more precise responses aligned with your brand. The platform is built on Anthropic’s Claude 4.5 Sonnet, giving it advanced reasoning and creative content generation capabilities. However, some features like content scheduling or metrics tracking depend more on integrations than on the AI itself.
Integrations
- Gmail
- Outlook
- Google Calendar
- Microsoft Calendar
- Google Drive
- Notion
- LinkedIn (personal and business)
- Facebook and Instagram (via Meta Business Suite)
- Strava (fitness tracking)
- QuickBooks (accounting)
- Google Analytics
There’s no WhatsApp integration, which is a significant limitation for businesses in Spain and Latin America where this platform is essential for commercial communication. Only the integrations listed in the Brain AI tab are available.
It’s important to note that Sintra doesn’t provide API capabilities or keys for connecting with other external services or platforms. All integrations must be done within the application through pre-defined connections. This could be a limitation for businesses with specific technical needs requiring custom integrations.
Data Security and Compliance
Regarding data ownership, the company states that no third party, apart from Sintra, has access to customer data. All intellectual property and private business data shared with the AI assistants remain exclusive to each user’s workspace and are stored securely in Brain AI. Additionally, user data is never used to train AI models—it’s only used to personalise the user’s own experience. Data retention extends until account deactivation or 2 years after the last login, depending on the data type. Personal data is retained for up to 3 years after the user stops using the services.
Regarding encryption, payment processing uses 256-bit encryption through Stripe. The assistants request explicit consent before performing actions on connected accounts and always inform users about the actions they’re about to execute.
Sintra is a US-registered company (Delaware) under playOS, Inc. Data may be transferred to the US and other countries. For transfers outside the EU/EEA, they implement standard contractual clauses approved by the European Commission. Users can manage their data through Brain AI settings, including the ability to delete uploaded materials or clear their agents’ memory.
Language – Customer Support and Interface
The Sintra AI interface is available in 12 languages including English (default), Portuguese, French, among others. This eases adoption for users who prefer to navigate the platform in their native language.
Customer support, including the AI agent Cassie and the human team, is available in multiple languages. Users can set their preferred language from the account settings section. Help centre documentation is available only in English.
AI Language
Sintra AI’s assistants support over 100 languages natively. The full list includes Portuguese, French, German, Italian, Arabic, Chinese (simplified and traditional), Japanese, Korean, Hindi, Russian, and dozens more from Afrikaans to Zulu. This means you can send messages to the AI agents and receive responses in your language of choice.
Notably, this multilingual functionality also applies to the pre-built AI tools designed to complete specific tasks in just a few steps. This is particularly useful for creating marketing content, responding to emails, or managing social media in various markets.
The platform is built on Claude 4.5 Sonnet, a language model trained on multilingual data. This ensures responses are grammatically correct and culturally appropriate.
Mobile Access
Sintra AI has dedicated mobile apps for iOS (version 15.0 or higher) and Android (version 7.0 or higher). The apps are available on the App Store and Google Play Store, with over 10,000 downloads on Android.
The mobile app includes the platform’s main features: access to all 12 AI assistants, notifications, activity logs, and workspace management. It also offers a 7-day free trial with the annual plan.
Support, Onboarding, and Account Management
Sintra AI offers various resources to facilitate platform adoption. It has a blog with educational articles, detailed case studies, and a help centre with documentation on different features. For more technical users, there are also guides on customising AI agents.
The onboarding process is designed for users without technical experience. The conversational interface allows you to start working immediately without complex configurations. The Brain AI system guides users with questions to progressively build the brand’s knowledge base.
Customer support is available 24/7 through the Cassie assistant, backed by a human team that, according to user reviews, stands out for its professionalism and quick response times. This is particularly valuable for SMEs without dedicated technical staff.
Ease of Use / UX
The interface follows an intuitive conversational design where users interact with assistants via chat. This significantly reduces the learning curve, as there’s no need to learn complex menus or specific workflows.
Some users mention that the number of available options—with 12 different assistants and multiple use cases—can feel overwhelming at first. However, once users become familiar with the platform and configure their Brain AI, the experience becomes smooth and productive.
An SME can start seeing good results from day one using the power-ups for pre-defined tasks. Deeper personalisation through Brain AI requires a few weeks of interaction for the system to learn enough about the business.
Pricing and Plans
The main plan is Sintra X, which includes access to all 12 AI assistants and all Brain AI features. The platform operates on a subscription model with monthly payment options, and frequently offers significant promotional discounts for new users.
Plans include a money-back guarantee, allowing you to try the platform risk-free. No programming knowledge or technical setup is required to start using the service, and users can cancel at any time.
We recommend visiting the official website for current pricing and active promotions.
Case Study
The owner of an online store in the United States represents a typical ideal Sintra AI user. Her business struggled to maintain a social media presence while simultaneously managing inventory and customer service.
After implementing Sintra AI, Michele delegated social media post management and advertising campaign planning to the Soshie and Buddy assistants. The platform even identified and proposed a solution for a duplicate social media pages issue she hadn’t noticed. This allowed her to focus on areas where her personal involvement was essential: product selection and direct customer relationships.
Tool vs Alternatives
| Feature | Sintra AI | Darwin AI | Jasper AI |
| Main focus | 12 agents for multiple business areas | Agents for sales, customer service, and collections | Content generation and marketing |
| Contextual memory | Brain AI with 5 profiles | Memory by phone number | Brand voice and knowledge base |
| Main channels | Gmail, social media, Notion, Google Analytics | WhatsApp, Instagram, calls | Browser, CMS, Google Docs |
| WhatsApp integration | Not available | Native | Third-party only |
| Specialised agents | 12 agents for different functions | 5 agents by commercial role (Alba, Sofía, Bruno, Eva, Lucas) | No agents—uses templates and document editor |
| Languages supported | 100+ languages | 80+ languages | |
| Ideal for | SMEs seeking comprehensive automation | SMEs with high WhatsApp and Instagram volume | Marketing teams and content generation |
Sintra AI occupies a middle ground between both alternatives. Compared to Darwin AI, Sintra offers a wider range of functions (SEO, recruiting, coaching, data analysis) but lacks WhatsApp integration, an essential channel in many countries. Compared to Jasper AI, Sintra provides specialised agents that go beyond content generation, including task automation and customer service, while Jasper focuses exclusively on marketing content production with tools like its long-form document editor. The choice depends on business priorities: Darwin AI for sales and conversational support via messaging, Jasper AI for high-quality marketing content, and Sintra AI for a comprehensive solution covering multiple areas without switching between platforms.
