You want to use AI at work: meeting notes, error logs, SQL, email replies, long documents, voice transcripts. But that information can't go out to the internet. A local AI runs inside your PC, and today's local AI can handle this kind of work. OnecaratEditor Core brings that local AI into the editor you write in.

Those same tasks, for real.
Huh. So that's how you'd use it.
…Could this fit the way I work?

The things you repeat can be wrapped up, just for you.
A small Python-like language that combines text handling with AI.
You don't have to write all the code: ask Coashi in plain words, and build it together.

Thanks for your help as always.
Could the materials we asked for move
from Oct 20 to Oct 24?Members who ordered 3+ times last month
(member ID, name, order count)
Thank you for reaching out.
Moving the date to Oct 24 works for us.
We look forward to receiving the materials.SELECT m.member_id, m.name, COUNT(*) AS orders
FROM members m JOIN orders o ON o.member_id = m.member_id
WHERE o.ordered_at >= DATE '2026-09-01'
AND o.ordered_at < DATE '2026-10-01'
GROUP BY m.member_id, m.name

In Carat Studio, ask Coashi in plain words what the macro should do.
Coashi returns Carat code that reads the selection, has the AI write the text with AIWRITE, and opens it with NEWTAB. You read it and insert it yourself.
Run it on the selected email: the reply draft opens in a new tab.
