Sunsama made the daily plan into a ritual. Pull your tasks in, drag them onto your calendar, shut the day down when it is done. It is a good product.
If you already talk to Claude or Codex all day, you may want the plan to come from them. You say what is on, they place it in your free time, and you skip the dragging.
That is the job of Context Board’s Calendar. It is one board type in a workspace that also holds dashboards, docs and a pipeline, so we compare it with Sunsama here for the part they share, planning the day. Context Board is ours, so weigh the bias. Prices below were checked on Sunsama’s own site on October 27, 2026.
What Sunsama is built for
Sunsama calls itself a task manager, calendar and daily planner. Its help center walks you through planning the day, and weekly planning centers on objectives you carry forward from last week. Tasks come in from tools like Asana, ClickUp, GitHub, Linear, Notion and Todoist, and from Gmail and Slack. It connects Google, Outlook, Apple and CalDAV calendars, and timeboxing a task creates an event on your calendar.
It has apps for iOS, Android, Mac, Windows and Linux. It also has AI of its own: an assistant called Sunny that can plan your day and manage tasks, and an MCP server for Claude, ChatGPT, Cursor and Claude Code.
Pro is $22 a month billed monthly, or $17 a month billed yearly. There is a 14-day trial with no card, and no free plan.
What the Calendar does
The Calendar shows your events and tasks by day, week and month, on your own clock.
Press N and type “Invoice Acme Friday 2pm 30m”, and the task lands on Friday at 2 PM for 30 minutes. Or click a time, or drag across the hours. Your content calendar’s posts and your pipeline’s follow-ups show on their days by themselves. Google calendars on the Calendar are coming soon. Until then, a calendar widget on any other board shows your meetings from a calendar’s iCal link, read only, and the Google Calendar page shows where to find that link.
Ask your agent to plan your day, with the tasks you want done, and it puts each one in a free time and tells you where. Events you placed yourself stay put.
Your own agent does the planning
The chat on the board runs on your own Claude Code or Codex plan, or on your own API key. So planning the day does not add an AI subscription.
Any app that speaks MCP can use the calendar too. From Claude Code, Codex or Cursor you can say “put the changelog on Friday at 2pm” or “plan tomorrow on my calendar”. Sunsama has its own assistant and its own MCP server, so this is not a case of one tool having AI and the other not. The difference is whose AI it is. Here it is the agent you already use for the rest of your work, and the calendar sits in the same workspace as the board that shows your revenue and your agents’ sessions. The board types page lists what else the plan holds.
What it costs
Sunsama Pro is $22 a month, or $17 a month billed yearly. That is $204 a year at the yearly rate.
Context Board is free for 3 days, then $12 a month, which is $144 a year. One plan covers every board type, widget and connection, so the calendar is not a separate line on your card.
Where Sunsama still fits
Pick Sunsama if you want the ritual spelled out. It guides the morning plan, runs weekly planning around objectives, pulls tasks from the tools your team already uses, and writes timeboxed tasks back to your calendar. It has native apps.
The Calendar is lighter. It is a web app with a phone view, your tasks live on the board, and Google calendars on it are still to come. If you are weighing more daily planners, Sunsama alternatives compares nine of them, and the AI productivity tools roundup covers the wider stack.
Try it with tomorrow’s tasks
Make a Calendar board and ask your agent to plan tomorrow, with the tasks you want done. If the plan is one you would have made yourself, you have saved the dragging.
