Efficio vs Open Sunsama

Efficio is a web-based digital planner and calendar combining tasks, time-blocking, and an AI scheduling assistant. Tasks can contain duration, priority, deadlines, descriptions, tags, and attached files. Users create categories with names, descriptions, colors, and scheduling parameters, then drag tasks on the calendar to change timing or duration. Calendar controls include time zones and date and time formats. The AI assistant can assign tasks to categories, organize uncategorized tasks, and fill schedule gaps with suitable work. Efficio says it syncs with Google Calendar and Microsoft Calendar, and supports sign-up with either account. The product is in beta; the site warns that features may change significantly and data may be lost, recommending backups. The free beta-tester plan offers early access and feedback features. Basic plans are listed at 10.00 USD monthly or 96.00 USD yearly, both currently unavailable.

Open Sunsama is a task manager and daily planner built around a board of days and calendar time blocking. Move tasks from a backlog to a daily board; unfinished work rolls over to tomorrow. Focus mode times a task and tracks actual time against its estimate. It syncs Google Calendar, Outlook, and iCloud, with support for multiple accounts. Time blocks stay in Open Sunsama rather than being copied to Google or Outlook calendars. Its hosted MCP server connects to Claude, ChatGPT, Cursor, and other MCP clients through OAuth and provides 24 tools. The REST API covers tasks, subtasks, and time blocks, with selectable API-key scopes. Users can also self-host the web app, API, MCP server, and PostgreSQL database using Docker Compose. The free plan costs nothing for personal use. The non-commercial license limits production use by companies, and there is no one-click export button. Desktop apps are available for Mac, Windows, and Linux; phones use the mobile web app, as no native phone app is available yet.
