The Hourglass
A weekly time-blocking tool for planning your typical week in 30-minute blocks, with an AI collaboration built in.
What it is
The Hourglass is a 7-day grid, Monday through Sunday, spanning 6:00am to 9:00pm in 30-minute blocks. You drag on empty cells to create a block, drag blocks to move them, and dragging a block onto occupied time cascades the existing blocks later in the day. It's designed to plan a typical week (the repeating shape you want to live in), rather than any specific calendar range.
Everything runs in your browser. Your data lives in local storage, not on a server, so no sign-in and nothing is sent anywhere. You can export your week as JSON and re-import it whenever you want.
The AI part
The interesting piece isn't the grid. It's how you fill it. Instead of hand-building a week from scratch, you use a prompt that turns any AI assistant (ChatGPT, Claude, Gemini, whichever you prefer) into a planning partner. It asks you seven questions about your work, movement, meetings, and habits, drafts a week back to you in prose, and hands you a JSON file to paste directly into the tool.
How to use it
- Get the planning prompt and paste it into your preferred AI assistant.
- Answer its questions. Adjust the draft it proposes until it fits.
- Copy the JSON it produces at the end. In The Hourglass, open the Import panel and paste it in.
