Online tools
- 01HengcangFor households with several accounts and currencies: pool everything into one ledger and see how far the Growth, Balanced and Defensive groups are from their targets. The web app lets you try a sample ledger without signing up; your own ledger needs an account. The Android app is open source.
- 02Investment DashboardsTwo public read-only dashboards: index allocation and recurring-investment watch, plus A-share short-term money flow. Scheduled jobs refresh the data snapshots that ship with the code.
- 03Character AtelierFor people who write novels or draw original characters: turn a character's looks, personality and background into one complete profile card. A few choices are enough, and trying it needs no sign-up; saving it to your own library needs an account.
Case studies & open source
- 01KnowledgeFor people whose knowledge is scattered across notes, manuals and PDFs: build a small, well-defined library on your own Windows computer, search a keyword and see which source and which passage of the original it comes from. Files stay on your machine; this is a prototype in a personal pilot. A read-only sample on the web needs no sign-up and shows keyword search on synthetic documents.
