You don't have a time problem.
You have a gaps problem.

Your day is full of small openings between meetings — twenty minutes here, forty there. They're invisible on a calendar, so they evaporate into inbox-checking. GapRail finds every one of them, across every calendar you juggle, and tells you exactly which task fits. Reclaim two hours a day you didn't know you had.

The hidden hours

Your calendar only shows what's booked. Never what isn't.

Six meetings looks like a full day. But look between them: forty minutes before the client review, twenty-five after the 1:1, a clean hour before planning. On a meeting-heavy day that's two hours or more of real, usable time — and it disappears, because no tool measures it and nothing tells you what would fit in it. A 25-minute gap is worthless if you spend the first ten minutes deciding what to do with it.

GapRail treats those unbooked minutes as what they are: the most recoverable time you have.

How it works

Three steps to your first reclaimed hour

1

Connect your calendars

Google Calendar today, as many as you juggle — work, personal, side projects. Read-only by default: GapRail looks, it doesn't touch.

2

Paste in your tasks

No re-typing into another system — paste your list and go. Every task gets an AI duration estimate automatically, even the ones you'd never think to time.

3

Work the gaps

GapRail lines your tasks up against your real openings and hands you the best fit for each one. One click schedules it. The decision fatigue is gone.

Not another to-do list

Your task app knows what needs doing. Your calendar knows when you're busy. Neither talks to the other — which is why every gap in your day starts with the same stalling question: what should I even do right now?

GapRail is the join. It reads the openings from your calendars and the work from your list, and answers the question before you ask it.

Two calendars. Zero surprises.

Work meetings on one calendar, life on another — and a double-booking waiting to happen. GapRail lays them on one rail, flags conflicts the moment they appear, and shows you the time that's genuinely free. Your whole life, finally on one rail.
