Show HN: PocketWise – a simple, natural-language double-entry finance tracker

How are you parsing the natural-language expense inputs into balanced double-entry transactions—are you using a rule-based grammar, a fine-tuned model, or an LLM-prompted parser, and how do you guarantee correctness (e.g., preventing unbalanced postings, ambiguous account inference, currency formatting drift, or daylight-saving-related timestamp inconsistencies) before writing to the ledger?

Consider me old-fashioned, but I have never been comfortable with my financial data sitting in someone else’s domain. Especially a third-party domain. General summary reports for legal or taxation on hard copy is one thing, the nitty gritty details in easily siphonable electronic format is a thorough hell naw.

Unless this is an installable app capable of doing 99% of everything offline and under my complete control, thanks but no thanks.
