| Description | Loisa is an open-source, self-hosted AI coworker that runs on your own machine using your own keys and data. It is built on the Hermes agent core, Composio (1,000+ tool integrations), and OpenViking, which stores a company-wide 'brain' as plain markdown files covering people, projects, customers, and playbooks. It connects to Slack, Telegram, WhatsApp, email, and other tools to run reporting, outreach, follow-ups, and approvals autonomously via triggers and cron. | Dia is an AI-native browser from The Browser Company (creators of Arc) that integrates with tools like Slack, Notion, Calendar, Gmail, and GitHub. It generates morning briefs, pulls together information spread across tabs and apps, answers context-aware questions about on-screen content, and helps users prepare for meetings. Aimed at knowledge workers, it is currently available only on macOS. |
