Switching from Todoist or TickTick
CSV import · also Apple Reminders and plain text
The worst part of leaving a task manager is the feeling that your system lives in it. It doesn't — it lives in you, and the data moves in about ten minutes. Both Todoist and TickTick export CSV files, and Jupiter Optimus reads them directly, on iPhone, iPad or Mac.
From Todoist
- In Todoist, open a project and choose Export as CSV. Todoist exports per project, so repeat for each project you want to keep.
- In Jupiter Optimus, open Settings → Data → Import from Todoist… and pick the file.
- Choose where those tasks should land — a project, or the Inbox. Because Todoist's file doesn't name its project, you decide per file.
Titles, notes, priorities (mapped from Todoist's inverted 1–4 scale), due dates and subtask structure come across. Completed tasks import as completed, so your history isn't erased by the move.
From TickTick
- In TickTick, go to Settings → Backup and generate a backup — it downloads as a CSV.
- In Jupiter Optimus, open Settings → Data → Import from TickTick… and pick the file.
TickTick's file names each task's list, so your lists become projects automatically — one file, whole system. Priorities map from TickTick's 0/1/3/5 scale, tags come along, all-day and timed due dates are kept, and nested tasks fold into subtasks under their top-level parent.
From Apple Reminders, or from anywhere
Settings → Data → Import from Reminders… brings your Apple Reminders lists across, after asking permission.
And if your tasks live in a notes file, a spreadsheet column, or your head:
Import from Text… turns pasted lines into tasks — one per line, with
the same quick-add grammar the app uses everywhere, so #tag, priorities
and dates written in the line are understood.
After the import
- Imports are additive and safe to repeat — importing the same file twice does not double your projects: same-named projects are matched, not recreated.
- Tasks with future due dates get reminders scheduled automatically.
- Everything syncs to your other devices through your own iCloud — nothing to set up.
What's different here, honestly
Things you will notice, so none of them surprise you a week in:
- Start dates are first-class. A task can say when you intend to begin, not only when it is due — and it stays out of your way until then. Todoist and TickTick largely blur this into due dates.
- No collaboration. Jupiter Optimus is a single-player tool. Shared projects and assigning tasks to other people do not exist here.
- No web app. iPhone, iPad, Mac and Apple Watch, native. If you live in a browser at work, that matters.
- No natural-language date everywhere — quick add understands dates in the line, but there's no "remind me every second Tuesday" prose parser.
- Issues are the headline. If your work lives in GitHub or GitLab, imports go both ways with your tracker — see the issues guide.
Your data stays yours
There is no account to create and no server receiving your import — the file is read on your device and stored in your own private iCloud database. Leaving is as easy as arriving: Settings → Data → Back Up All Data writes everything to a plain JSON file you can read.
