In their own words

KerrOS Calendar

KerrOS Calendar schedules meetings, recurring tasks, automations, and AI workers, and can trigger events across KerrOS products. Its AI scheduling uses priorities and availability to find meeting times and protect deep-work blocks. The calendar identifies overlapping working hours and adjusts schedules across time zones. Recurring events can be configured once, with recurrence, rescheduling, and reminders handled afterward. Events connect to Automator workflows that can start workers, send notifications, process data, or launch other automation chains. Native links include KerrOS AI Chat, Hub, Tasks, and CRM, with two-way syncing for task deadlines and milestones. KerrOS also lists integrations such as Slack, Google Drive, GitHub, Outlook, Notion, Jira, Salesforce, and others. It runs on Linux, macOS, Windows, web, or self-hosted hardware, with hybrid cloud and dedicated cluster options. Pricing is freemium: a free plan, a 14-day trial, and Pro at $20 a month billed monthly.
