Ledgerly

Personal finance apps fall into two camps. Either you hand over your bank credentials to an aggregator and let an opaque server see every transaction you make, or you give up and stop tracking anything at all.

Both options are bad. The first is a privacy disaster waiting to happen. The second is why most people don't actually know where their money goes.

Ledgerly inverts the model. All processing happens on your device. You photograph a receipt, a statement, a screenshot. An on-device vision model parses out merchant, amount, date, category. The result lands in a local Postgres-backed ledger that never crosses the network.

The interesting engineering is the inference latency. Mid-range Android phones running int8-quantized vision models in the background, with results that feel instant. Getting that to hold under poor conditions (low light, crumpled receipts, mixed languages) is most of the work.

In active development. The vision pipeline works end-to-end on a stable beta channel; current focus is hardening the parser against the long tail of weird receipt formats.
