What I'm building.

MarginDeck brings product revenue, scheduled costs, and estimated contribution profit together on your Mac, with a menu bar brief for quick checks between deeper reviews. Version 1.5.1 improves English and Simplified Chinese text and fixes language-switching and display issues.

• Check revenue, cost, or contribution profit from the menu bar, with a comparison against the full previous month when saved history is available.
• See the next 7 or 14 days of scheduled costs, including annual charges, and open the underlying details.
• Choose a weekly financial check-in reminder and see when revenue was last saved.
• Compare recorded revenue, scheduled costs, and estimated contribution profit over 6 or 12 months.
• Build local monthly RevenueCat and Stripe history from successful 1.4 syncs onward.
• Convert supported amounts into estimated totals in your display currency while preserving original amounts.
• Allocate shared costs across products and keep working data local to the Mac.

SnapQuizX is a Chrome extension that generates AI quizzes from a webpage, PDF, or pasted text, and keeps a notebook of the questions you get wrong so you can come back and review them.

• Generate a quiz from the page you're already reading, no copy-pasting into a separate app.
• Save missed questions to a notebook and revisit them later.
• Works for quick anonymous practice or a signed-in account that keeps your history.
