Your AI-powered personal and business assistant in one place
Atom unifies calendars, messages, tasks, and business tools, letting you manage personal life and small‑business operations through natural language and AI‑driven automation.
Atom is an AI‑driven assistant that brings together your personal and professional digital life. By connecting calendars, email, chat platforms, project‑management tools, and financial services, it offers a single conversational interface for scheduling, communication, task tracking, and small‑business operations.
You can interact with Atom via voice or text, asking it to find meeting slots, summarize meetings, draft replies, or generate financial insights. All data processing can run locally on your machine or in a private cloud, ensuring privacy. Installation requires Node.js 16+, 2 GB storage, and 8 GB RAM for optimal performance, and works on Windows, macOS, and Linux.
Ideal for busy professionals, entrepreneurs, and developers who want a unified, privacy‑first productivity hub without juggling multiple apps.
When teams consider Atom, these hosted platforms usually appear on the same shortlist.
