Macro vs. HeyBrain

Macro is an open-source AI workspace designed to unify communication, collaboration, knowledge management, and customer relationship management within a single application. The platform replaces separate email clients, messaging tools, document editors, task managers, CRM systems, and AI assistants by bringing them together into one connected environment. At the core of Macro is a shared AI memory that continuously learns from emails, documents, chats, meetings, tasks, and CRM activity, allowing AI agents to understand the full context of an organization's work. Its keyboard-first email experience combines fast navigation, unified inboxes, AI-assisted writing, intelligent search, and streamlined message management to improve productivity. Teams can collaborate through markdown-native documents that support real-time editing, version control, AI-assisted writing, and direct links to conversations, tasks, and other workspace resources. Integrated messaging channels connect discussions with emails, documents, projects, and customer records so information remains organized instead of scattered across multiple platforms. Macro's task management system lets users instantly convert messages into actionable work items, assign priorities, delegate execution to AI agents, and automatically track progress through development workflows. The integrated CRM provides AI-generated customer summaries by combining contacts, emails, meetings, tasks, documents, and organizational memory into a single account view before sales or customer success interactions. Because Macro is open source, organizations can inspect the codebase, customize features, deploy the platform on their own infrastructure, and integrate it with existing workflows. Enterprise-grade security includes SOC 2 Type II certification and zero data retention with supported AI providers to help protect sensitive business information.

HeyBrain is an enterprise AI knowledge management platform that provides a shared information layer for employees, teams, and autonomous AI agents. The software enables organizations to centralize approved documents, operational procedures, project information, business decisions, and other knowledge resources within a hosted workspace. Its AI memory capabilities preserve useful context for retrieval across compatible assistants, allowing users to reference information from previous projects and conversations. The platform includes a searchable knowledge base that supports natural language questions and generates responses accompanied by references to underlying sources. Users can organize company knowledge into shared collections and maintain information about document ownership, versions, and intended access. HeyBrain supports manual document uploads and integrations with Google Drive and Notion, with available connections depending on account permissions and configuration. Its Model Context Protocol integration allows compatible AI clients, including Claude, Cursor, and Codex, to retrieve authorized company information through connected tools. Organizations can maintain reusable agent instructions and provide task-specific knowledge to AI agents without embedding the same information separately into every workflow. Governance features help administrators evaluate user identities, agent access, document permissions, and the information available to connected AI tools. Activity review and source citation capabilities support oversight of knowledge retrieval and help users verify the information underlying AI-generated responses. HeyBrain also supports workflows that use different AI models and existing subscriptions, enabling businesses to manage shared organizational context independently of individual AI assistants.
