Smart Pen
An AI app for a client: I built the credits-and-payments system it charges through, and a real-time voice assistant.
01Credits that cannot be forged
A credit wallet with a full ledger, a pricing engine and an admin billing panel, in the database rather than the app. Apple and Google purchase receipts are verified on the server; the device is never trusted to report a purchase.
02Live voice without exposing the key
The phone never talks to the AI provider directly. The server holds the key and relays the call: a one-time ticket opens it, only one call per user runs at a time, and it is billed by the minute from credit reserved up front, with the remainder returned.
03Since October: the story studio
A story and manga studio with its own characters, a reader whose pages turn, films made from a story’s own pictures and voices, motion videos with a library of 100 sound effects, and reminders that ring with a study plan built from exam dates.
04Shipped
Released on the App Store and Google Play through store review, under the client’s name, and on the web.
05What you can check yourself
Each row is a source you can open or a method you can repeat.
