What your assistant can do in Sunlet

Tasks it saves show up in Sunlet on the web, your computer and your phone. Each reply says what was saved or changed, before and after, and how to undo it.

  • Save next steps

    Up to 10 tasks save at once, with days, times and estimates. Larger batches, up to 20, are shown to you before they're saved.

  • See today's plan

    Open tasks for your local day, the estimated total, overdue work and how many tasks still have no estimate.

  • Find tasks

    By words, day or date range, list, tag, or whether they're done.

  • Move and edit

    Change a day, time or detail. Anything you don't mention, like the deadline, stays as it is.

  • Finish tasks

    Mark tasks done. A repeating task gets its next occurrence, just as in the app.

  • Undo any change

    Every change can be undone, on every plan. If you've edited the task since, Sunlet says so instead of overwriting it.

Connect your assistant

You sign in to Sunlet once and choose Allow. Each assistant gets its own connection, which you can remove at any time.

Other MCP clients

Any app that supports remote MCP servers with OAuth can connect. Add a remote server with the URL; the app registers itself and opens Sunlet's sign-in.

Things to ask your assistant

  • “Save the next steps from this conversation in Sunlet.”
  • “What's on my plan today in Sunlet?”
  • “Help me plan tomorrow in Sunlet.”
  • “Find my Sunlet tasks about the launch.”
  • “Move “Prepare quarterly report” to tomorrow.”
  • “Mark “Water the plants” as done in Sunlet.”
  • “What's overdue in Sunlet?”
  • “Undo that.”

You stay in control

Your assistant only gets in after you sign in to Sunlet and press Allow, and only to your tasks.

  • The task details your assistant reads go to its provider, such as OpenAI or Anthropic, and are handled under that provider's privacy policy.
  • Sunlet keeps which apps you connected, when, the permissions you allowed and a record of each change so you can undo it. It never receives your conversations.
  • Disconnect any time in Settings → Connected apps. Access stops at once; your past chats stay with the assistant.
  • It can't delete tasks, create, rename or archive lists, or see a calendar. Sunlet has no calendar connection yet, so it won't claim you have free time.

Free on every plan

Every connector feature works on every Sunlet plan, including Free. Your assistant does the thinking, so it doesn't use your Sunlet Assistant requests or Week planner moves. Your plan's usual limits still apply: on Free, that's 3 active lists and 100 open tasks.

Questions

What is MCP?

The Model Context Protocol is an open standard that lets AI assistants use other apps. Sunlet runs an MCP server at sunlet.app/mcp that your assistant talks to.

Which apps can connect?

Claude (web, desktop, phone and Claude Code) and any app that supports remote MCP servers with OAuth sign-in. ChatGPT's plugin directory listing is in review.

Do I need a paid plan?

No. Every connector feature works on Sunlet's Free plan, and your plan's usual limits still apply: Free has 3 active lists and 100 open tasks.

Can my assistant delete my tasks?

No. It can save, find, move, edit and complete tasks, and undo its own changes. Deleting tasks and changing lists stay in the Sunlet app.

What happens when I disconnect?

The assistant loses access straight away. Tasks it saved stay in Sunlet. To use it again, connect it again.

Can it see my calendar?

No. Sunlet doesn't connect to a calendar yet, so your assistant only knows your tasks and their estimates.

Try it with today's tasks.
