Web service guides

A compatibility and daily-fortune tool that puts Saju (day master, ten gods) next to the 16 MBTI types. For entertainment, not a reading practice.

A small delivery tool: upload a roster, scan a QR when you arrive. Also notes on when it is the wrong tool.

A terminal that puts KRX candles, retail/foreign/institution flow, and news summaries on one screen. It is not investment advice.

Play Gomoku in the browser. Rules for five-in-a-row on a 15×15 board, three AI levels, and local two-player mode.

A browser platformer across four themes: underground, ground, sky, space. Covers spikes, fake ledges, and recovering from a fall.

Turn purchase price and expected lifespan into cost per day, and times used into cost per use. Data stays in your browser.

Tag gift screenshots to a person and get an on-device reminder before their birthday. No account — data stays in this browser.

Collect Maps, Pinterest, and social saves with a why-note and a 1–5 want-to-go rank. Not a day-by-day itinerary — a local inbox. No account; data stays in this browser.

Fit a photo or signature to the exact width×height and min/max KB a form asks for. No government autofill. No account — processing stays in this browser.

Save a link with a required why-line, keep at most 3 for this week, and let unpinned items expire after 30 days. A shrinking list — not a Pocket-style library.

Log leftover names and eat-by dates. Not FridgeBuddy, eggg, or pecco — no inventory, login, or AI. Data stays on this device.
