AI Email & Workflow Automation Platform
Beta testing • Free to try
Sunday is your AI chief-of-staff for digital communications. Built on our MAGK (Multi-Agent Knowledge Graph) framework, Sunday unifies your inbox, automates triage, and extracts actionable insights—so you can focus on what matters. It's not just another email tool; it's an intelligent system that understands context and learns from every interaction.
We're building a central AI assistant that connects to all your digital tools—email, messaging, calendar, notes, and more. Sunday empowers you to focus on high-value work while AI handles the busywork, with a seamless human-in-the-loop experience for trust and control.
Most email tools treat your inbox as a static list of messages. Sunday sees it as a dynamic knowledge graph where conversations connect to people, projects, and commitments. This shift from message management to context understanding is what makes Sunday different. It doesn't just show you emails—it understands what they mean and what you need to do about them.
Sunday aggregates Gmail, Outlook, and other platforms into a single, intelligent dashboard. Instead of jumping between inboxes, you get one unified view where AI understands the full context across all your accounts. Threads are automatically connected, duplicates are merged, and important conversations surface regardless of which account they came from.
The system doesn't just display messages—it builds a knowledge graph of your communications, tracking relationships, projects, and commitments across every platform you use. This unified intelligence means Sunday can spot patterns and connections that would be impossible to see in fragmented inboxes.
Sunday automatically prioritizes, categorizes, and flags important emails and threads using machine learning trained on your behavior. The system learns what matters to you—not through rigid rules, but by observing which emails you respond to quickly, which ones you archive immediately, and which conversations demand your attention.
Over time, Sunday's triage becomes eerily accurate. It surfaces urgent requests before they become problems, filters out noise without missing important updates, and adjusts priorities based on your calendar, deadlines, and work patterns. It's like having an executive assistant who knows your priorities better than you do.
Long email threads become concise summaries highlighting action items, deadlines, and key decisions. Sunday doesn't just extract information—it understands context, tracks commitments, and identifies what actually requires your attention versus what's informational.
Every morning, you get a daily briefing that synthesizes your most important emails, upcoming meetings, and pending tasks. It's not a chronological dump of everything that happened—it's an intelligent digest of what matters, why it matters, and what you should do about it.
Sunday generates one-click AI-powered responses in your tone, with easy review before sending. The system learns your communication style by analyzing past emails, understanding how you handle different situations, and adapting to the formality and tone appropriate for each recipient.
For routine requests, Sunday can fully automate responses with your approval. Need to decline a meeting? Acknowledge a request? Provide standard information? Sunday drafts the response, you approve with one click, and it's sent. You stay in control while eliminating hours of repetitive communication.
Sunday detects tasks, commitments, and reminders from emails and automatically syncs with your task manager. When someone asks you to review a document by Friday, Sunday extracts that commitment, creates a task, sets the deadline, and links it back to the original email for context.
The system tracks these commitments across your entire inbox, sending reminders before deadlines and surfacing related emails when you're working on a task. It's the connection between your email and your actual work that other tools miss.
Sunday builds a persistent knowledge base tracking people, projects, and conversations for context—your second brain. When you're preparing for a meeting, Sunday surfaces relevant past conversations, commitments you made, and context you need without requiring you to search.
This is where the MAGK framework shines. Instead of treating every email as an isolated event, Sunday maintains a living graph of your professional relationships and projects. It remembers context from months ago, connects seemingly unrelated threads, and provides the institutional memory that's impossible to maintain manually.
Sunday is built on our Multi-Agent Knowledge Graph (MAGK) framework, enabling AI agents to remember context, learn from interactions, and improve over time. This isn't just a buzzword—it's the architectural foundation that makes Sunday different from every other email tool.
Traditional AI systems process each email independently, with no memory of past interactions. MAGK maintains a persistent knowledge graph where every email, task, person, and project connects to everything else. The system doesn't just respond to queries—it builds deep understanding of your work context across all interactions.
AI without memory is just expensive autocomplete. MAGK makes Sunday truly intelligent, enabling it to provide context-aware suggestions, predict what you need before you ask, and continuously improve its understanding of how you work. The longer you use Sunday, the smarter it gets.
Sunday reviews and surfaces proposed actions for your approval before execution, ensuring trust and transparency. We don't believe in AI that acts autonomously without human oversight— that's a recipe for mistakes that damage relationships.
Every automated action, generated response, and suggested task goes through you. Sunday handles the heavy lifting of drafting, analyzing, and organizing, but you make the final decisions. This human-in-the-loop approach means you get the efficiency of automation with the judgment that only humans can provide.
