The App Gallery · free for everyone
Every card below is a real mini-app you can build in Claude in about five minutes — no code, no signup beyond a free claude.ai account. Copy the prompt, paste it into Claude, and remix from there. New apps land in the Beginners in AI newsletter every week.
Find out what 'only $9.99 a month' actually adds up to.
Most people underestimate their subscription spend by hundreds a year, and every forgotten free trial is counting on it. One honest session with this app usually pays for itself on the spot.
Create an interactive artifact: a subscription audit tracker. Let me add each subscription with a name, price, billing cycle (monthly or yearly), category, and a 'when did I last actually use this?' picker with options like this week, this month, and can't remember. Show a dashboard up top: total per month, total per year, and cost by category. Give each row a verdict toggle — keep, downgrade, or cancel — and show a 'money you'd free up' banner totaling what my cancels would save per year. Pre-load five example subscriptions so I can see it working, and let me delete them. Add a 'copy audit summary' button that produces clean text of my totals and cancel list. Everything in React state, no login or saving. Friendly style: rounded cards, cheerful colors, and gently judgmental copy when I pick 'can't remember'.
You get: A sortable subscription list with keep/downgrade/cancel verdicts, monthly and yearly totals, and a running 'money you'd free up' number that gets very motivating.
Your data: Your list lives only while the artifact is open — copy the audit summary out when you're done, or paste your bank statement into the chat first and ask Claude to bake the subscriptions in before building.

One big number: how many months your money lasts.
Budget apps bury the only number that matters under forty categories and a login screen. This answers 'am I okay?' in one glance and updates with a single paste each month.
Create an interactive artifact: a personal runway dashboard. Inputs panel: cash on hand, monthly take-home income, and a list of monthly expenses I add by category. Dashboard: a big 'months of runway' number (cash divided by the monthly shortfall, showing 'you're cash-flow positive' when income covers expenses), monthly burn rate, a bar chart of spending by category, and a 12-month projected-balance line chart. Add a what-if slider that trims all spending by 0 to 30 percent and shows how the runway number moves. Include a 'paste my numbers' box that accepts simple lines like 'Rent: 1400' and fills the expense list for me, so updating each month is one paste. Start with realistic example numbers I can overwrite. React state only — no login, no saving. Friendly style: calm, reassuring colors, big readable numbers, zero finance-bro jargon.
You get: A dashboard with your runway in months front and center, burn and category charts, a what-if slider, and a paste box that swallows your monthly numbers in one go.
Your data: Built paste-to-update: each month you paste fresh numbers into the app's paste box (or into the chat and ask Claude to rebuild it) — nothing syncs to your bank, and nothing persists between visits unless you're on Pro and publish it with persistent storage.
