Graylin gives you a personal AI pod — your own AI workspace that manages tasks, automates workflows, handles contacts, and works across channels. It's not just a chatbot. It's a capable assistant with its own tools, memory, and personality. CHAT WITH YOUR AI Have natural conversations with your AI assistant. Graylin streams responses in real time, remembers context across sessions, and supports media attachments. Organize conversations into projects for easy reference. MANAGE TASKS A full task board with drag-and-drop Kanban columns: backlog, todo, in progress, blocked, done, and more. Your AI can create and update tasks for you, or you can manage them yourself. AUTOMATE WORKFLOWS Build multi-step automations with triggers and actions. Graylin's workflow builder lets you create powerful automations — from scheduled tasks to event-driven pipelines — with AI-assisted step creation.
