Slate is a task planner that sits between a calendar and a to-do list. Tasks go on the day you actually plan to do them, no fake time blocks required, and anything not ready for a specific day yet sits in a separate backlog instead of cluttering the week.
Easy to try: no sign-up wall to poke around (though more advanced AI features would not be accessible)
I made this because I never trusted either extreme. A calendar makes you fake commit to a time slot... A to-do list takes anything with no judgment about what belongs this week, so it just grows forever.
Some of the harder parts to get right:
1- Sync + drag&drop: Drag and drop needed to feel instant, but everything also syncs live across devices through AppSync/DynamoDB with optimistic concurrency: Getting those two to not fight each other (a drag mid-flight racing a subscription echoing your own write back at you) took a few rewrites... crazy how those simple things can be so hard to get right.
2- UI: keeping the UI minimalist and nice on mobile after building this first for desktop.
I'm still down in the mine adding features nobody asked for (voice-to-task, add-task-through-whatsapp,...): please come be my first users so I have a reason to climb out, stop building and start talking to people instead
