@gaborudvari No special prompt, I just open a ledger file in Zed and give claude a list of transaction from bank statement (it very likely adds the whole ledger to context and shares it with server, so I consider this ledger public). I check that sums and currencies are correct and slightly adjust the naming/ask to group related transactions. Then repeat the same operation for the transactions of the next day.
I tried to do same with chatgpt-4o this summer, but it generated a lot of nonsense.
