The name Chaya in Hebrew letters is חיה. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
חיה
In short
Your name in Hebrew letters is חיה. A Hebrew name, חיה, “living”, from the same root as חיים, “life”. It is the feminine partner of the name Chaim. Adding up the numbers of its letters gives 23. That number points to Torah page 23 of 354 — in the portion Lech Lecha. What that portion is about: “Go forth”: Abraham leaves Haran; the promise of land and offspring; the covenant between the pieces; circumcision. The verse that begins with the first letter of your name and ends with the last is Genesis 25:15. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Chaya” — this exact spelling is what was calculated: חיה. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
And she called the name of HaShem that spoke unto her, Thou art a G-d of seeing; for she said: 'Have I even here seen Him that seeth Me?'
This is from the portion Lech Lecha. What it is about: “Go forth”: Abraham leaves Haran; the promise of land and offspring; the covenant between the pieces; circumcision.
Other ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
with finals and ordinal — 23.
Reduced, each letter to one digit (mispar katan) — 14. A Torah word with the same number is יד — “hand” (Genesis 3:22).
Cumulative: a letter plus all letters before it (mispar kidmi) — 106. A Torah word with the same number is נון — “Nun, father of Joshua” (Exodus 33:11).
Squares of the letter values (mispar perati) — 189. A Torah word with the same number is פקדה — “oversight, visitation” (Numbers 3:32).
Building: the sum grows with each letter (mispar bone’eh) — 49. A Torah word with the same number is מואב — “Moab, son of Lot” (Genesis 19:37).
The letters that come out are סמצ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 190. A Torah word with the same number is כנען — “Canaan, son of Ham” (Genesis 9:18).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 444. A Torah word with the same number is מקדש — “sanctuary” (Exodus 15:17).
The number 23 appears in the classical books 5 times across 5 works. The earliest mention is עץ חיים (~1573).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 23. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.

For an engraving, a sign or a tattoo, show the spelling to someone who reads Hebrew: transliterating a name is a choice, not the only option.
The name חיה appears in the Torah as a word 17 times. The first time is Genesis 1:20. Another 22 times it stands with prefixes — “and”, “in”, “the”.
The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For חיה these are ח and ה. The Pentateuch has 3 such verses. The first of them is Genesis 25:15:
חדד ותימא יטור נפיש וקדמה
This is from the portion Chayei Sarah. What it is about: Sarah's death and the purchase of the cave of Machpelah; the servant seeks a wife for Isaac; Rebecca at the well; Abraham's death.
Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
