MySundayUse cases
Point at it. Say it.
It's done.
MySunday works on the web (your own app on localhost, and reference pages you have the rights to use), in Google Docs, Sheets and Slides, and in Word and Excel on your Mac. These are the sentences people use with it, and what happens when they do.
Your page and a reference
Four things builders do with it.
01 — Move
“Move this here.”
Point at an element, then at the place it belongs. The agent moves it in your source, not just on screen.
02 — Match
“Use this as a reference.”
Point at a component in your project and at a reference you own or are authorised to use. Your agent uses the reference to guide your component’s styling, keeping your own content, assets and design tokens.
03 — Fix
“Fix this.”
Select what looks wrong. The agent sees the same misalignment you do and fixes the cause in your layout.
04 — Interaction
“I want this kind of interaction here.”
Point at an interaction on a reference you own or are authorised to use, then at your own page. Your agent implements the behaviour you asked for in your codebase, with your own content and styles.
On video
Scroll effect
AvailablePoint at items that stack as a page scrolls, then at three of your own, and ask to keep your colours and content.
Animation
AvailablePoint at cards that fan out on a reference page you have the rights to use, then at the products in your own store, and ask to keep the store looking as it does.
Another animation
AvailablePoint at cards that slide over each other on a reference page you have the rights to use, then at your own cards, and ask to keep your design.
MySunday helps you implement what you point at in your own code, from references you own or are authorised to use. You are responsible for having the rights to any reference material you use, and MySunday is not for copying or redistributing other people’s content. Terms.
Documents & spreadsheets
In your documents.
Point at what to use, then at where it goes, in Google Docs, Sheets or Slides. The edit waits for your Apply.
In Word and Excel on your Mac it rewrites the text you select, and in Excel it fills the cell you point at; nothing changes until you confirm.
Presentations
AvailablePoint at a slide whose design you like, then at another slide in the deck: the design is carried across to it.
Spreadsheets
AvailablePoint at the data in a sheet and ask for a summary by region with a chart, then point at where it goes: "Right here."
Spreadsheet to slide
AvailablePoint at a chart in a sheet, then at the place on a slide in another tab. The chart is carried across between two apps.
Email and calendar
AvailablePoint at the date a message proposes and say "Book this." The free slot is found and the meeting booked from the mail once you say yes.
Documents
AvailablePoint at three paragraphs of a document, then at the empty line where the summary goes: three bullets, with links back to what they came from.
Rewrite in place
Select text in a field, a page or another app and ask for it shorter, simpler or more formal. You see the old and the new text and nothing changes until you apply it; Undo puts it back.
How rewriting worksOn one page
No second site needed.
Everything you point at can be on the page in front of you. The last two are new: they don't change your code at all.
“Make this look like that.”
Both on one page: point at the plain button, then at the one you like. The first takes on the second’s style.
“Move this here.”
Point at a section and at the gap where it should sit. The agent reorders it in your source.
“Fill this with …”
NewPoint at a box on any website or in a Mac app and say what goes in it. You confirm it first, it goes in and the form is never sent; no code changes.
“Why did this happen?”
NewPoint at an error or a broken layout. Your agent reads the page, your code and recent console errors and answers what caused it; nothing is edited.
Beyond the page
Your apps, your documents, your own voice.
Ask about anything
Press ⌃⌥Space (Control-Option-Space) to ask about the site you are on, your code, or text you selected in any Mac app. You get an answer; nothing is edited.
Voice that runs on your Mac
Press ⌥Space (Option-Space) and talk. Speech recognition and the spoken replies run on your Mac by default, and then your audio does not leave it.
Wake word and gesture
Say “Sunday”, or draw your own symbol with the pointer, to start voice hands-free. The wake word is off until you turn it on; gesture wake is on as soon as you save a symbol.
Talk to a box
Talk to Sunday and point at a box, on any website or in any Mac app, and say what should go in it. Sunday shows you first, and nothing goes in until you say yes. A floating icon on your page and your screen turns voice on and off, and you can hide it.
On video
Ask about anything
AvailablePoint at a spike on a dashboard chart and ask what it means, then at a dip. You get an answer; nothing is edited.
How to use it
- Start voice
- Press ⌥Space (Option-Space). The microphone stays open while you talk and point; press it again or say goodbye to stop.
- Point
- While voice is on, rest the pointer on an element in Chrome for a moment to point at it, then say “this”, “that” or “here”.
- Ask about anything
- Press ⌃⌥Space (Control-Option-Space) to ask about the page you are on, your code, or text you selected in any Mac app.
- Continue your session
- Pick one of your own Claude Code or Codex sessions in the Session select (or say “in my Claude session”) and the request goes into that conversation instead of a fresh run.
- Wake word
- Say “Sunday” to start voice without the hotkey. It is off until you turn it on in Preferences.
- Gesture wake
- Draw your own symbol with the pointer to start voice. It is on as soon as you save a symbol in Preferences.
These are the shortcuts MySunday starts with; change them on the app's Settings → Sunday.
The vocabulary
The most useful words in human collaboration barely work with AI.
- THIS
- The thing I’m pointing at
- THAT
- The other one, over there
- HERE
- The place I mean
- THERE
- The place you can see
- THESE
- All of the ones I selected
- “Move THIS → HERE.”
- “Make THESE look like THAT.”
- “Why did THIS happen?”
We're teaching AI to understand the language humans already use.
Try it on your own project.
macOS app and Chrome extension. Your code stays on your machine; your own Claude Code or Codex does the edits.
