愛憎 — both
sides of every
good tool.
aiZoo takes its name from the Japanese aizō (愛憎) — the simultaneous presence of love and hate. A useful frame for software: it can solve problems and create new ones, sometimes at the same time.
What lives here is built quietly. Some pieces are dashboards over public data, some are small apps for narrow circles. The common thread is restraint — local-first when it matters, no accounts, no cookies, no tracking, often open source.
