Open Sunsama vs Reclaim AI

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.

Reclaim AI is a calendar assistant that works with existing calendars to organize schedules around work and life priorities. Reclaim 2.0 combines a calendar, Planner, AI Assistant, and background Agents. Changes made through the assistant or MCP integrations are staged in Preview Mode before they reach the live calendar. It supports Google Calendar and Outlook Calendar, and lists integrations such as Slack, Jira, Asana, Google Tasks, Todoist, ClickUp, Linear, Zoom, and Webhooks. MCP clients include ChatGPT, Claude, Cursor, Copilot, and Gemini. Reclaim is primarily a web app and can be installed as a Progressive Web App through Chrome or Safari; it has no native iOS or Android app, though its web app is designed for mobile use. The Lite plan is free forever for one user and includes a one-week scheduling range, one calendar sync, one scheduling link, and five AI Agents. Starter costs $12 a month, Business $18 a month, and Enterprise $22 a month with contact required. Reclaim says it is SOC 2 Type II certified and committed to GDPR, CCPA, and Data Privacy Framework standards.
