Sunday
new Sutra is now Sunday — see what's new

A personal AI that lives on your Mac.

Sunday remembers what you tell it, reads your documents and email, researches the web and works in your tools — with its memory in plain markdown files you own. It asks before anything goes out.

Works with the tools you already use

Features

Knows your context. Does the work. Asks first.

Sunday ties together your notes, decisions, plans, inbox and learning — and remembers, so you don't have to.

Memory you own

Everything Sunday learns about you lives in plain markdown files in a folder on your disk. Open them in Obsidian, edit them, back them up however you like.

  • Before every reply, it recalls the notes that matter to what you just said.
  • Search runs locally, with on-device embeddings.
  • Delete the folder and it's gone. No cloud copy.

Always asks before acting

Reading is free. Anything that sends, posts, buys or changes something waits for your yes — with exactly what will happen spelled out first.

  • Approve from your Mac, your phone or Telegram.
  • Never types passwords and never deletes for good.

Learns your way — with your OK

Correct how it did something, or let it finish a long task, and Sunday may draft a short procedure for next time. Nothing changes until you read it and approve it.

  • Edit a draft before approving it.
  • Turn off or delete any skill later.

And more

One assistant for the rest of your day.

Hands builds to coding agents

“Have Claude Code add dark mode to my blog.” It runs in the background; watch each step, then see exactly what changed.

Researches the web

Searches, reads any page or PDF as clean text, and pulls in whole documentation sections at once.

Reads and writes documents

Drop in a resume, a receipt or a PDF and it remembers it. Ask for a report or a deck and get a real PDF, .docx or .pptx.

Helps you learn for real

Study plans from real sources, then flashcards on a spaced-repetition schedule so it sticks.

Everyday apps

Expenses from a sentence or a receipt photo, calories from a plate photo, and workouts that tell you when to level up.

Routines on a clock

“Every weekday at 9, find three new AI jobs for me.” Runs on its own and reports back.

Connects your tools

Sign in to Notion, Jira, GitHub or Slack with a click, or add local MCP servers just like in Claude Desktop.

Your Chrome, when needed

Sites like Gmail block automated browsers. The Sunday extension uses your signed-in Chrome instead — only its own tabs, every click approved.

Or message it on Telegram

Pair Telegram once to ask, trigger tasks and approve with a tap. It only ever answers your account.

FAQ

Questions, answered.

Is Sunday free?

Yes. Sunday itself is free. It uses AI models through your own OpenRouter key, so you pay OpenRouter only for what you use.

Does my data leave my Mac?

Your notes, files, email and logins stay on your Mac. Only the model calls go out, with your own key. Remote access is off until you set it up.

Which Macs does it run on?

Macs with Apple Silicon (M1 or newer), with Node.js 24 or newer installed.

Do I need Obsidian?

No. Sunday's memory is a folder of markdown files. Obsidian is a nice way to browse and edit them, but it's optional.

Can I use it from my phone?

Yes. Run sunday remote setup on your Mac and pair your phone at app.sundaybot.me, or pair Telegram. Sunday keeps running on your Mac.

Is Sunday the same as Sutra?

Yes. Sutra was renamed to Sunday in version 0.1.8. Your data carries over, and the sutra command still works.
