Analyze budgets and research investments from bank data
The poster pipes bank transaction data into ChatGPT and uses Claude for budget analysis, investment research, and summarizing and comparing financial reports.
Done with a custom-built or unnamed agent
- What they did
- The poster says they use WisePenny to pipe transaction data from their bank accounts into ChatGPT without handing over bank logins or broad third-party permissions, then use Claude for the analysis work. In the thread they describe using Claude to build budgets from spending history, summarize and compare companies’ financial reports, and help research investments rather than directly controlling accounts.
- How it went
- The source gives no hard performance numbers; it presents this as a practical read-and-analyze workflow. In comments, others stress keeping the setup read-only or local and not letting Claude manage money autonomously.
- Worth knowing
- The clearest catch is security: the poster says they avoid sharing bank login details, and a commenter says their own local setup keeps financial data entirely on-device.

Finish with a one-page summary and a cleaned spreadsheet, and do not change or delete my original files.
