Who each one suits

Akiflow

  • People whose tasks are spread across email, chat and project tools
  • Planning each day by time blocking tasks around meetings
  • Keyboard-driven users who want a command bar and shortcuts

Open Sunsama

  • People who want Sunsama-style daily planning with code they can read
  • Planning a day through Claude, ChatGPT or another MCP client
  • Individuals who want to self-host their planner with Docker

Worth knowing

Akiflow

  • There is no free plan, and the 7-day trial requires a card.
  • Monthly billing costs $34 per month, against $19 per month on the yearly plan.
  • The AI Meeting Assistant (recording, transcripts, summaries) is a separate $19-per-month add-on.
  • Desktop downloads are listed for macOS and Windows only, and team pricing is arranged with sales.

Open Sunsama

  • The license is non-commercial: personal, educational and non-profit use is free, and for-profit companies need an enterprise license with no public price.
  • There is no native phone app yet; on a phone it runs as a mobile web app in the browser.
  • The desktop apps connect only to opensunsama.com, so a self-hosted install is used through the web app.
  • Team workspaces, auto-scheduling and integrations with Linear, GitHub, Jira and Notion are unchecked roadmap items, not shipped features.

Key features

Akiflow

Universal inbox
Tasks from connected tools such as Gmail, Slack, Notion, Asana, Jira and Todoist land in one inbox. Zapier and IFTTT cover tools without a native integration.
Time blocking on the calendar
Place tasks on a calendar that syncs with Google Calendar and Outlook Calendar, so planned work sits next to meetings.
Aki AI assistant
Ask Aki by chat or voice to plan, prioritize or move work, for example clearing an afternoon and pushing tasks to the next day. Included in Pro.
Availability sharing and booking
Share open slots or a meeting link so other people can book one-off or recurring meetings with you.
Command bar and shortcuts
Create, edit and navigate tasks from the keyboard. The command bar also turns copied text from a web page into a task.
MCP connector
Connects Claude, ChatGPT or another MCP client to your Akiflow tasks, calendar and meetings.

Open Sunsama

Kanban board of days
Tasks sit on a board with a column per day and a backlog. Each task can carry a P0 to P3 priority, a time estimate, subtasks, rich-text notes and attachments.
Drag-and-drop time blocking
Dragging a task onto the calendar creates a block linked to that task, and resizing the block sets its length. The calendar has day, 3-day, week and month views.
Calendar sync
Events from Google Calendar, Outlook and iCloud appear next to tasks and time blocks, so a day is planned around existing meetings.
Focus mode and rollover
Focus mode shows one task with a timer and records actual time against the estimate. Unfinished tasks roll over to the next day, and recurring tasks repeat on their own.
MCP server for AI agents
A hosted MCP server with 24 tools lets Claude, ChatGPT, Cursor and other MCP clients read the schedule and create or move tasks and time blocks after an OAuth sign-in.
REST API and self-hosting
A REST API with scoped API keys covers tasks, time blocks and ideas. The app can be run on your own server with Docker Compose, which starts PostgreSQL, Redis, the API and the web app.
