Luma on a made-up vault. Acme and the people in it are fictional.
How it works
Notes, tasks and time, in one vault.
Everything lives in the same folder of Markdown files, so a task written in a meeting note shows up in the calendar, and the time spent on it lands back in the note.
01Projects and tasks
A task is a Markdown checkbox in any note, with a priority, a due date and hours. One view gathers them all, from overdue to later.
02Calendar and daily notes
Month, week and day views place the tasks on their date and hours. Drag a task to move it, click a day to open its daily note.
03Focus and history
A Pomodoro timer on a task adds the time spent to the task line, and the history shows where the time went, per client, project and tag.
04Ask your vault
A local model run by Ollama answers questions about your notes and tasks, and shows the notes it used. Off by default, read only.
Promises
It's a folder on your Mac.
Your notes should outlive the app you write them in. Here is what Luma commits to, in one place.
A file you can read.
Every note is a plain Markdown file, in a folder you choose.
Open it anywhere.
Any other editor reads your notes, and an existing Obsidian vault opens as is.
Your sync, your repository.
Sync is optional, and goes to your own GitHub repository through the Git of your Mac.
Nothing lost in a conflict.
When two edits collide, both versions are kept.
AI that stays on your Mac.
The assistant talks to a model running on your own computer through Ollama. No note is sent anywhere, and it stays off until you turn it on.
