Decide what's actually moving
You're very likely not deleting anything. The pattern that comes up again and again in the comparisons on this site is that people keep Notion for the wiki, keep Slack for the company they actually work at, and move the one thing that was never those tools' job in the first place: the day-by-day plan. Decide which half of your setup is genuinely the day-planning half before you move anything.
Coming from Notion
Notion can export a database or page as Markdown or CSV from its own export menu. Fuidzy's importer reads both formats and creates a task per row or per page. Tasks land in the unscheduled tray rather than guessing a time for them — you decide when each one actually happens, which is the whole point of leaving a list-shaped tool in the first place.
What doesn't move: relations, rollups and any database structure specific to Notion's model. If a page was really a wiki entry rather than a piece of work, it's honestly better left in Notion — that's still the better tool for it.
Coming from Todoist, TickTick or any task list
Most task apps can export an open list as CSV somewhere in their settings or via a template export. Fuidzy reads CSV the same way. The one honest limitation: recurrence rules don't travel between apps' formats, so a task that repeated every weekday in your old app needs its recurrence re-created in Fuidzy — a couple of clicks, not a re-typing job, but worth knowing before you start.
Coming from a calendar
Fuidzy imports standard .ics calendar files from Google Calendar, Outlook or Apple Calendar. Very long recurring series are worth re-creating as a native Fuidzy recurrence rather than relying purely on the import, since an .ics file only contains the occurrences it was exported with rather than an infinite forward pattern.
Coming from Slack
There's nothing to export here, because Slack doesn't hold tasks — it holds the conversation people have instead of a shared plan. The actual move is to stop answering "what's everyone working on" by scrolling a channel, and start a Clan: create one, share the join code with your group, and set each person's share level. "Who's free this afternoon" becomes something the app answers rather than something someone has to ask.
Export Notion pages/databases as Markdown or CSV · export any task app's open list as CSV · export calendars as .ics · rebuild recurring items as native recurrences · move a Slack team's coordination into a Clan rather than trying to export a conversation.
