Sentinel connects your email, calendar, tasks and messages into one intelligent assistant that helps you understand what matters, act faster and stay in control.
For busy founders, executives, operators and professionals who are tired of missed follow-ups, scattered information and constant context switching.
Sentinel is an AI assistant that understands your world and helps you manage it.
Sentinel brings your emails, calendar, tasks and key updates into one place, so you do not need to jump between tools to understand what needs your attention.
Important follow-ups, meetings, deadlines and requests are surfaced automatically, helping you stay ahead before things slip.
Sentinel reduces admin, preparation time and manual checking by summarising context, drafting next steps and helping you act faster.
Give trusted people controlled access to help with messages, tasks and availability without losing visibility or control.
Most people lose control because everything is spread across too many places.
Important decisions, requests and commitments are hidden inside long threads, old emails and scattered conversations.
Meetings show what is booked, but not what needs preparation, what changed, or what should happen next.
Assistants, colleagues and family members often need context, but giving access is either too limited or too risky.
Generic assistants can answer questions, but they do not understand your real schedule, relationships, responsibilities and ongoing commitments.
Sentinel helps you manage the key parts of your day through one intelligent workspace.
Sentinel can summarise threads, highlight important requests, detect follow-ups, draft replies and help you decide what needs action now.
Sentinel connects to your calendar to help you prepare for meetings, understand your day and identify conflicts or gaps.
Sentinel helps capture commitments from emails, meetings and messages, then organises them into actionable tasks.
Sentinel makes it possible to share selected access with assistants, colleagues, family members or trusted contacts. You decide what each person can see or do.
Sentinel gives your assistant, team or trusted contacts the context they need while keeping you in control.
Stay ahead of meetings, investor updates, client conversations and operational follow-ups without living in your inbox.
Get the right context, manage requests faster and support the principal without needing constant clarification.
Keep track of work, family, appointments, travel, documents and commitments in one place.
Coordinate availability, tasks and important updates with clear permission boundaries.
Sentinel becomes more useful as it understands more context. It can help you answer questions such as:
You decide who can connect with you, what they can access and which channels they can use.
Instead of broad account-level access, Sentinel uses relationship-based permissions. Each connection can have its own settings.
Give someone access to your availability without giving them access to your tasks. Allow proxy chat without opening direct communication. Keep every role specific.
Sentinel is designed for sensitive personal and professional workflows where privacy, clarity and control matter.
Start by connecting the systems you already use, such as Gmail and Calendar.
The assistant organises your emails, meetings, tasks and key information into a searchable, useful memory.
Use Sentinel to understand what is happening, prepare for what is next, create tasks, respond faster and let trusted people help where appropriate.
Sentinel helps you understand it, act on it and safely share the right parts of it with the right people.
Sentinel is connected to your real context, not just a blank AI chat box.
Tasks are linked to emails, meetings, people and decisions.
Delegation is permission-based, visible and controlled.
Sentinel keeps humans in control while reducing repetitive admin and missed context.
