One-Screen Monday

Your whole week on one screen before your coffee goes cold.

Weekly reviews die inside 14-tab planning systems. This is one screen: what happened last week, what matters this week, what goes where — done in ten minutes every Monday.

Show the prompt ▾
Create an interactive artifact: a one-screen Monday weekly planner. Layout: a 'Last week' column with wins and carry-overs I type in, a 'Top 3 this week' section with three big priority slots, and a Monday-to-Friday board where I add small tasks under each day and tick them off, with a progress bar up top. Include a text box where I can paste a messy brain dump and a 'Sort it for me' button that uses Claude to turn the dump into suggested top-3 priorities and day-by-day tasks I can accept or edit. Add a 'Copy my week' button that copies the whole plan as clean text for my notes app. Keep everything in React state — no login, no saving. Friendly style: calm colors, rounded cards, everything fitting on one screen without scrolling on a laptop.

You get: A planner that genuinely fits on one screen — and it thinks for itself: paste a brain dump and a Claude-powered button sorts it into priorities and days (works on the Free plan, and anyone you share it with uses their own account).

Your data: Nothing saves between visits — end each Monday with the 'Copy my week' button and paste the plan into your notes, or on Pro, publish the artifact and ask Claude to add persistent storage.

Remix it

  • Add a 'Friday shutdown' mode that turns this week's unfinished tasks into next Monday's carry-over list.
  • Add an energy tag to each task — deep focus, admin, or calls — and color the board by it.
  • Make the Sort button also suggest one thing I should drop entirely, and explain why.
  • Add a weekend lane and a separate 'life admin' lane below the work week.

The Meeting Meter

A taxi meter for meetings. Watch the dollars tick.

That weekly status call with nine people 'just to sync' has a price tag nobody has ever calculated. Once you watch it tick past $400 in real time, the agenda writes itself.

Show the prompt ▾
Create an interactive artifact: a meeting cost calculator. Inputs: number of attendees, average hourly cost per person (with a hint that salary divided by 2000 is roughly hourly), and meeting length in minutes. Show a big, bold total cost that updates as I type, plus what the same meeting costs per week and per year if it's recurring. Include a 'live meeting mode': a start button that ticks the cost up second by second, like a taxi meter. Add a playful comparison line (like 'that's 34 burritos') and a gentle verdict — under $100 is fine, $100 to $500 says trim the invite list, over $500 asks 'could this be an email?'. Keep all state in React, no login or saving. Friendly style: big numbers, warm colors, a touch of humor, and it should look great on a phone.

You get: A calculator with a big live total, recurring-cost math, and a taxi-meter mode you can screen-share at the start of a meeting for maximum effect.

Your data: Nothing to store — you punch in fresh numbers each time, which takes about ten seconds.

Remix it

  • Add role presets — exec, manager, individual contributor — with different hourly rates instead of one average.
  • Add a 'could this be an email?' decision quiz: five questions, one verdict.
  • Let me list all my recurring meetings and show my total weekly meeting bill.
  • Add a projector-friendly full-screen mode showing nothing but the ticking number.
