Can I code Motion?

A calendar and a task list are both buildable on their own. Motion's actual product is an algorithm that automatically re-slots your tasks around meetings all day, every time something changes — genuine scheduling-optimization research, not a feature.

VIBE SCORE 86/100

how this is worked out

A moderate score here just means the individual parts are buildable — it isn't a build/buy recommendation on its own. Read "why CanICodeThis says Just pay" below for the actual reason this one's still JUST PAY.

Why CanICodeThis says Just pay

A calendar view and a task list, shown side by side, are both well-bounded builds this register already covers separately
Manually dragging a task into a calendar slot yourself is straightforward drag-and-drop
For someone happy to schedule their own tasks around meetings, that manual version is genuinely a weekend project

Read before building

Automatically re-optimizing your entire day's task schedule every time a meeting is added, cancelled, or runs long is a real constraint-satisfaction/scheduling-algorithm problem, not a calendar feature
Balancing task priority, deadlines, and estimated duration into one optimal schedule, continuously, is applied operations-research territory
Getting the auto-scheduling wrong in an annoying way (constantly reshuffling your day) is worse than not having it — this is a case where the hard part is also the point

The build spec

Don't build automatic task-rescheduling. Build a calendar-plus-task-list view instead: see your meetings and your task list side by side, and manually drag tasks into open calendar slots. That covers real day-planning needs; continuously auto-optimizing your whole schedule around a constraint solver is genuinely the hard, differentiated part of the real product.

What it actually costs to build

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.

AI agent — with a subscription (Claude Pro/Max, Cursor, etc.)	$0 marginal
AI agent — pay-per-use API, no subscription	$86–$172 one-time
Hosting, once it's running	$0/mo (free tier)
Domain name, if you want your own	~$12/yr

Motion costs $34/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 6 months.
