Skip the budgeting app. Use Claude to audit subscriptions, find missed tax deductions, negotiate bills, pressure-test big purchases and track your net worth. 10 tasks, each with a copy-paste prompt.
Privacy ground rules (read this first)
Never paste full account numbers, Social Security numbers or full card numbers into any AI chat. These prompts work with exported data like statement PDFs and transaction CSVs, or screenshots that show only the last 4 digits. Redact before you paste. Claude doesn’t need the full number to do the work.
Not financial advice
This is a toolkit, not advice from a CPA, CFP or tax pro. For taxes, investing or anything legal, use Claude to prep for the conversation with a real professional. The prompts surface what to discuss. A real advisor confirms the moves.
Each task has a copy-paste prompt. Turn on web search for the ones that need current prices or rules, and attach your export with the paperclip or + button.
Run it quarterly. Drop in a 3-month bank and card export. Claude lists every recurring charge, flags the dead ones, the duplicates and the price creep, and tells you how to cancel each.
Run it monthly. Export your transactions and get back a categorized table, spending by category and the patterns you’d miss. No budgeting-app subscription needed.
Run it before tax season. It walks through your job, side income and life, then surfaces deductions worth raising with your CPA. The 2025 tax law added new ones for tips, overtime, car loan interest and people 65+ (IRS summary), and it ended the home energy credits after 2025. The prompt already knows to check.
Run it once a year per bill. Internet, cell phone, insurance, gym. Claude finds current competitor offers and writes the call script, including what to say to every retention line.
Use it before anything over $1K. “Should I buy this?” Claude pressure-tests it and surfaces the regret before the money’s gone. No lecture, just an honest second opinion.
Use it before any investment. Get the case for and the case against in 10 minutes instead of 2 hours of YouTube, with web search on so it pulls recent data. Then take it to an advisor for the actual decision.
Set it up once. Make a Claude Project, click Set project instructions, paste this in and save. Open it monthly to log income and expenses, and save the running log it gives you into the project’s files. Tax season becomes an export instead of a panic.
Build it once, update it monthly. Claude builds this as an interactive artifact. The export button matters: it keeps your history safe even if you start a new chat.
Run it quarterly. Pull your free reports from all three bureaus at AnnualCreditReport.com (free every week now), redact them and paste. You get the 3 moves that matter for your report, not a list of 30.
Runs on the 1st of every month. Scheduled tasks are on paid plans. Connect Google Drive and Gmail first (how), keep your exports in a Drive folder called “Money,” then paste this into a chat and ask Claude to schedule it monthly, or use Scheduled in the left sidebar (Anthropic’s steps). You spend 15 minutes reading the draft it leaves you.
If you only run one, make it Task 1. Forgotten subscriptions are the easiest money you’ll ever get back.
Then layer in Task 4 on your two biggest bills and set up Task 10 as a scheduled task. Three tasks, one weekend, and the review keeps running every month after that.
