Description
Castworth shows you what's coming in your money, starting with your income, so you can make better decisions, big and little. With Castworth in ChatGPT, you can go through your money in plain conversation: - Ask "What's new?" to see new charges waiting to be sorted, grouped into easy piles with Castworth's hint for each, plus any bill or paycheck that was expected but hasn't shown up yet. - Sort one charge or several at once into your spending categories, mark one as one-time, add a note, or match it to a planned bill or paycheck. - Mark money that came in, like interest or a refund, as income. - Share a receipt or order and Castworth works out the split to the penny, with tax shared out, before anything is saved. - Plan a bill or income, add a set-aside for something coming up, and set money aside for it from your Excess Cash. A set-aside only earmarks money already in your account. Nothing moves at your bank. - Ask how anything in Castworth works, like what Excess Cash means. You stay in charge. ChatGPT asks for your OK before any change, every change is recorded, and you can undo it. Castworth never moves money: it has read-only access to your bank and only organizes and forecasts. It isn't financial, tax or investment advice. Who it's for: people with a Castworth account who want to keep their forecast up to date by talking it through. You'll need a Castworth account (adults 18 and older) to connect. You can disconnect anytime in Castworth under Account, then Privacy and data. Limits: Castworth only sees accounts you track in Castworth. It can't pay bills, move or transfer money, or change anything at your bank. Some changes, like ones Castworth would ask "are you sure?" about in the app, have to be made in Castworth itself.
