Products

Things being built under Aulvem — what's currently live, and what's in the works.

Services

Hosted web services built and run under Aulvem — things you open in the browser rather than download. Free to use, no account required, and built on a zero-fixed-cost stack so they can stay up without a subscription behind them.

Yasugoro — a real-price watcher that tells you when and where to buy

Yasugoro is a price watcher that compares the real price (display price minus reward points) across Japanese marketplaces — Rakuten, Yahoo!, Amazon and others — and sends a Web Push when a staple you're watching actually gets cheaper. No login, used anonymously.

Spreadsheet

Templates built in Excel and Google Sheets for shared households and personal routines. Each one ships with multiple colorways and is ready to download, open, and run from the first cell — budgets, expense logs, and other workbooks you'll want to open every month.

Password Manager Sheet — Personal Edition

A single Google Sheet for taking stock of your logins, subscriptions, and what's due for rotation — all on one dashboard. For Japanese-speaking users.

Futari Kakeibo — Muted Linen Edition

A muted-beige / linen colorway of the Futari Kakeibo template — the calmer, more grown-up version that sits well in a shared living room. For Japanese-speaking households.

Futari Kakeibo — Sky Apricot Edition

A cool sky-blue and apricot colorway of the Futari Kakeibo template. Light, easy to read, and a kinder dashboard for the early-morning household budget check. For Japanese-speaking households.

Futari Kakeibo — Sakura Duo Edition

A shared household budget template for two — in a soft sakura-pastel palette. Splits shared and personal expenses, runs your custom split ratio, and tells you who owes whom each month. For Japanese-speaking households.

Notion

Notion templates for power users who live inside the app. Built around interlinked databases so projects, knowledge, prompts, and instructions stay in one place — one-click duplicate from the post-purchase PDF, with sample data included so you can see the wiring before customizing.

Claude Projects Knowledge Vault — Notion Template

A Notion template for Claude power users — projects, knowledge files, custom instructions and prompts in one place, so the next conversation can pick up where the last one left off.

Datasets

Structured reference data for cross-border e-commerce and audit-facing work. Each record ships with source URLs, retrieval timestamps, confidence rationale, and a change log; English master and a Japanese view, in both JSON and CSV, with a JSON Schema (Draft 2020-12) included for Python, R, Excel, and BI tools.

Shōhyō (証憑) — verified ground truth for Japanese invoice & receipt extraction

A labeled evaluation dataset for measuring document-to-JSON extraction on Japanese invoices and receipts. Japanese-era dates, reduced vs standard tax, withholding, qualified-invoice rules and revenue stamps are arithmetically verified on the answer side. Free sample on Hugging Face.

EPR Compliance Pro — Snapshot v0.1 (cross-border e-commerce regulation dataset)

Packaging EPR and de minimis import thresholds for DE/FR/IT/ES/NL/GB/US — with source URLs, confidence rationale, and a change log. Built to slot into ISO / SOC 2 audit trails.

Airline pet policies for Japan-outbound travel — sourced reference dataset

Cabin, checked-baggage, and cargo pet policies for 10 international airlines on Japan-outbound routes: weight and carrier limits, brachycephalic breed restrictions, required documents and fees. Each record carries a source URL, a verification date, and a confidence rating.

Cross-border product recall dataset — cosmetics, baby, and food (US / EU / Japan)

Thirty product recalls across cosmetics, baby products, and food from four authorities — US CPSC and FDA, the EU Safety Gate, and Japan's Consumer Affairs Agency. Each record carries the official recall ID, hazard type, remedy, a source URL, and an append-only timeline with verification dates.
