The AI that already knows your day.
Say “Hey JOI” while staring at a confusing email. She already read the thread, checked your calendar, and drafted a reply that sounds like you. No pasting. No explaining. She just knows.

// EVERY MORNING
Open your Mac.
JOI already knows what matters.
No digging through email. No checking three calendars. JOI scans your inbox and schedule and gives you the rundown the moment you open your laptop — what's urgent, what's on deck, and what needs your attention first.
Good morning. Here's your day:
3 urgent emails
Budget approval from Sarah (needs response)
Client contract revision (deadline today)
Team standup notes from yesterday
Today's schedule
10:00am — Q3 Budget Review with Sarah
1:00pm — Lunch (blocked)
2:00pm — Conflicts with Design Review — want me to reschedule?
Anything else before you dive in?
// SHE SEES WHAT YOU SEE
Ask a question. She already sees the answer.
Toggle screen context and JOI reads what's on your screen — code, designs, spreadsheets, error messages. No screenshots. No copy-paste. Just ask.
Other AIs
you: I see an error in my code
ai: Can you paste the error message?
you: [copies error, switches tabs, pastes]
ai: Can you also show me the surrounding code?
you: [more copying, more pasting...]
JOI
you:What's wrong here?
joi: Line 47 — you're passing a string where it expects a number. Change userId to parseInt(userId).
She saw the code. You didn't paste a thing.
// SHE REMEMBERS EVERYTHING
Every other AI starts from scratch.
JOI picks up where you left off.
She learns you
JOI writes herself notes about you — your preferences, your schedule patterns, your communication style. After a week, she knows you prefer bullet points over paragraphs. After a month, she drafts emails that sound like you wrote them. She doesn't just remember facts. She remembers you.
You shape her
JOI has a personality file called soul.md. Open it. Rewrite it. Tell her to be direct, or warm, or sarcastic, or professional. She's not a fixed product — she's an AI you shape into exactly the assistant you want.
# soul.md
You are JOI. Be direct and concise.
Skip pleasantries. Lead with the answer.
Use humor when appropriate.
Always sound like a sharp colleague,
not a customer service bot.
// ALWAYS ONE KEYSTROKE AWAY
She's just... there.
JOI lives in your menu bar. Hit a key and she's there. Say “Hey JOI” and she's listening. She collapses when you don't need her and expands when you do. No app to open. No tab to find.
