Rock vs Microsoft 365 Copilot and Sintra: a team that does the jobs, not just helps you write.
Microsoft 365 Copilot is an AI assistant inside Word, Excel, Outlook and Teams. Sintra offers a set of AI helpers for jobs like social media and email marketing. Rock is different: five AI team members that each run a real part of your business, working together on top of the systems you already use.
What sets Rock apart
What you get with Rock
- Five AI team members, each with a real job. Customer questions (Pearl), bookings and orders (Marina), supplier costs (Coral), admin emails, documents and proposals (Manta), and operations and early warnings (Horizon).
- They work as one team. They share what they know and get smarter every week, with your approval. One sign-in, one set of roles, one place for your data. No plug-ins or automation tools between them.
- Sits on top of your systems. It works with the booking system, calendar, till, stock and email you already use, through self-setup connectors. No integration project, and ready the same day.
- You stay in control. Nothing is sent until a person approves it, new answers are only used after the owner approves them, and anything it isn't sure of is flagged for a person to check.
- Data safety first. Built privacy-first in the UK, for GDPR. It uses only your information, never trains an AI model on your data, encrypts bookings, and always tells people it's AI.
- Your customers are yours, not ours. We take only what each job needs, encrypt it, and delete it on a timer, with booking details and finished emails removed after 30 days (or sooner if you choose) and Wave photos and notes as soon as the order is done. We never sell it, never use it to train AI, and never take your customers' payments, so no card or bank details ever pass through Lagoona. Your dashboards show facts, never personal details.
- Dashboards for every level, and every client. From one location to a region to the whole group, and for IT partners across all their clients, each person sees just their part, with suggestions and priorities: what changed, what to do next, and which site needs you first.
- Proof, not promises. Money found, customers turned away, early warnings and time saved, so you can see it paying for itself.
- Scales as you grow. Add locations, regions and brands under one account, for single sites, chains and IT partners.
- Add more agents with a switch. Start with one and turn on more in your account, with no new system to set up: the Guest suite (Pearl, Marina and Wave), the Business suite (Rock: Pearl, Marina, Coral, Manta and Horizon), Reef for IT, or all of them. Same sign-in, same dashboards.
- White label. IT partners resell it under their own brand, and chains can have a different brand for each group.
- Connects out with webhooks. Bookings can be sent, signed, into your own system, Zapier or Make.
- One flat price. Running costs included up to a limit, with no per-user charges. Or buy it once and run it in your own environment, with the source code, for full control (the IP stays with Lagoona).

Is Sintra good?
Yes. It offers a wide set of helpers for marketing and content. Rock is for businesses that want customer service, bookings, costs, admin and operations handled, joined up, with dashboards that prove it.
Do I have to change my systems?
No. Rock sits on top of the booking system, till, stock and email you already use.
