Yoonseul
Does the name fill what the chart lacks?
Birth date → the four pillars → the element the chart is short on, matched against the sound of each name.
Names are hard to change once they’re on paper — and hard to shake once people start calling you by them. Baby names, new names, English names, nicknames, stage names, handles, pets and shops: compare your candidates or get suggestions, read against the Four Pillars and the birth chart, pronunciation, family & partner fit and your own wishes.

Why a name matters
Said out loud several times a day — tens of thousands of times in a life.
What research has observed
People with easier-to-pronounce names were judged more favorably.
Laham, Koval & Alter, J. Exp. Soc. Psych. (2012) ↗Stocks with easy-to-say names outperformed right after listing — fluency matters for brands too.
Alter & Oppenheimer, PNAS (2006) ↗People prefer the letters in their own name — a name quietly shapes what feels “mine”.
Nuttin, Eur. J. Soc. Psych. (1985) ↗Korean naming reads every sound as Wood, Fire, Earth, Metal or Water — and looks for the one a birth chart is short on.

A cultural tradition, not a prediction.
Changing a name usually means a court petition, then every document, account and certificate. Deciding carefully now is far easier.

Every result is computed by a deterministic engine — the same input always gives the same answer, and the method is published in full. The narration is written by an AI that reads the engine's output and can't change a single grade. No human reviews your reading, which is why it arrives instantly and why we refund any factual error in full.

The birth chart (Four Pillars and Sun/Moon/Rising when you give the details) and each name’s sound-element flow and number. The ranking, the pick and all reasons open with one ticket.
1 ticket opens 1 full reading. Packs: 1 for $19, 3 for $45, 6 for $79 — each with question credits (1 credit = 1 answer). Tickets never expire and are charged in USD only.
From published popular-name lists (Korean birth statistics, US Social Security data; for pets, Rover’s most popular dog names and Korean pet-registration rankings). If too few listed names contain your must-include letter, we pair it with syllables used in the same position in listed names. Every suggestion is scored by the same engine as your own names, and any that trip a practical red flag are dropped.
Yes — up to six people. Each name is read against their chart (if you add a birth date) and said next to their name.
Any name someone will call out: a baby’s name, a new legal name, an English name, a nickname, a stage or pen name, a gamer tag or handle, a pet’s name, or a shop or brand. Nicknames, stage names, handles and business names are compared from your own candidates — we don’t invent those.
The Four Pillars and the birth chart are the base of every reading. For a baby it’s the birth or due date, for a pet the birthday or the day they came home, for a business the founder’s birthday. The time and city stay optional.
Leave it blank. We skip the hour pillar and the rising sign instead of guessing, and the reading says what was skipped.
No. The math is real (almanac, planetary positions, spelling data); the interpretation is a tradition, not a forecast.
