A to-do pile and a calendar are not a plan. This AI day planner template installs one employee, Day Planner, that reads both every morning and saves a timeboxed plan for the day as a file. It plans your own work; it does not book meetings with other people, which is the territory of scheduling and admin.
Biilda is a free desktop app for Windows and macOS where you describe what you want in chat and it builds AI employees (its word for an AI agent with a job), skills and scheduled tasks.
What this template does
Day Planner runs every morning and turns your calendar and your own notes into one clear, timeboxed plan for the day.
Every morning at 8:00 it reads today's Google Calendar (if connected), the todo/notes files you keep in your granted folder, and yesterday's plan for anything left unfinished — then writes a fresh `day-plan-YYYY-MM-DD.md` with your top three priorities up front, a timeboxed schedule with real buffer between blocks, and any carried-over items from yesterday called out explicitly.
It works fully from your files alone — no calendar connection required. If Google Calendar isn't connected, it plans around your notes and to-dos only and says so plainly at the top of the plan, rather than pretending the day is emptier than it is.
It only writes the plan file. It never touches your calendar, sends anything, or messages anyone on your behalf.
What does a timeboxed daily plan from AI look like?
At 8:00 the Day Planner gathers three things: today's Google Calendar if connected, the to-do and notes files in a folder you grant, and yesterday's plan, to catch anything unfinished. With the Day planning skill it writes a file named for today's date. Your top three priorities come first, then a timeboxed schedule with real buffer between blocks, demanding work in the morning, carried-over items named explicitly, and a shutdown checklist.
Honesty is built in. If Google Calendar is not connected, the plan says so at the top and plans around your notes only, rather than pretending the day is emptier than it is. The task is daily, so each day gets its own plan file in a folder you can scan, and no further app is needed.
What do you need to set it up?
A folder with your to-do or notes files. Google Calendar is optional.
- Download Biilda and open it.
- Open Templates and find Day Planner.
- Add it in one click.
- Grant your notes folder with your computer's own folder picker. Optionally connect Google Calendar from Connectors.
- Review what was installed, then switch on the employee and its task. They start off.
It is free to download with no subscription, and credits start at $20. The daily plan runs on Economy, the cheapest tier, and costs what it uses (pricing).
What can you change?
How much room the day gets is set in the Day planning skill: change the buffer between blocks, or how many priorities it picks. What it reads is yours too, since the plan is only as good as the notes you point it at. For timing, move Plan my day to whenever you start your day; it plans today from today's calendar. If you want more careful sequencing, try Balanced.
What does it not do?
It writes a file and nothing else: no calendar events, no reminders, no messages to anyone. It cannot know about commitments that appear in neither your calendar nor your notes. Scheduled tasks run only while Biilda is running, so no plan is written if Biilda is quit.
