MySundayUse cases
Point at it. Say it.
It's done.
MySunday starts with the web: your app on localhost and any site you admire. 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
“Make this look like that.”
Point at your component and at one you admire. Colours, spacing, type and shadows come across in your own 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 interaction… here.”
Point at a hover, an accordion or a transition on another site, then at your page. The behaviour is rebuilt in your code.
On 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 field on your local page and say what goes in it. You confirm the value, it is typed into the field and the form is never submitted; no code changes.
“Why did this happen?”
NewPoint at an error, a spike or a broken layout. Your agent reads the page, your code and recent console errors and answers what caused it; nothing is edited.
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.
