Domain check
This usually takes about 2 seconds. RDAP catches the case where a domain is registered but currently has no nameservers (expired-redemption, parked, just-registered).
Every phonic in the name carries weight. Here's what each segment does — read left to right.
Fast, crisp, innovation
X is the innovation letter. From X-ray to Tesla Model X, X-prefix signals 'next-generation'. Also a great suffix — Brex, Latex, FedEx, Netflix. The KS-cluster makes any name feel sharper.
e.g. Xerox · Xbox · Tesla Model X · Netflix · Brex
Small, precise, individual
I is the smallest character on the keyboard. Used for personal/lightweight brands (Instagram, iPhone). Apple's i-prefix is the modern naming canon. Front-vowel I makes things feel sharp and small.
e.g. iPhone · Instagram · Intel · Imgur
Decisive, definite
D is B's gentler cousin. Decisive but not aggressive. Used in consumer trust brands (Dropbox, Dasani, Dell).
e.g. Dropbox · Dasani · Dell · Duolingo · Discord
Round, bouba, full
O is the bouba/kiki experiment's round letter — across every language tested, a round shape gets associated with O-sound. Cross-cultural roundness. Best for friendly, premium, container/orb brands.
e.g. Sonos · Roku · Volvo · Otto · Onfido
Rolling, robust, ready
R conveys motion and roll. Less smooth than L (English R is more forceful). Used for action brands (Rivian, Roku, Reddit, Ralph Lauren). R also doubles as a sci-fi register (Robocop, R2D2).
e.g. Rivian · Roku · Reddit · Ralph Lauren · Revolut
Small, precise, individual
I is the smallest character on the keyboard. Used for personal/lightweight brands (Instagram, iPhone). Apple's i-prefix is the modern naming canon. Front-vowel I makes things feel sharp and small.
e.g. iPhone · Instagram · Intel · Imgur
Neutral, natural, nurturing
N is M's twin. Slightly less embracing but warm. Noom, Nike, Nubank, Netflix. Pairs especially well with double-O (Noom) — the bouba round-mouth shape.
e.g. Nike · Noom · Nubank · Netflix · Notion
Deep, you, communal
U is communal — Uber, YouTube, Yum!. Also reads as 'you' in product brands (Unsplash, Udemy).
e.g. Uber · YouTube · Udemy · Unilever · Unsplash
Noisy, alert, attention-grabbing
S is what a snake does — hiss for attention. Stripe, Snap, Slack, Spotify, Sonos. The most populous brand-starter letter for that reason. Pairs with anything.
e.g. Stripe · Snapchat · Slack · Spotify · Sonos

First-letter feeling
X-onset: Fast, crisp, innovation
X is the innovation letter. From X-ray to Tesla Model X, X-prefix signals 'next-generation'. Also a great suffix — Brex, Latex, FedEx, Netflix. The KS-cluster makes any name feel sharper.
Examples: Xerox · Xbox · Tesla Model X · Netflix · Brex · Latex

How we check. Step 1 (client-side): POST /api/check
with xidorinus.com. The function hashes the SLD against our bloom
filter (built daily from the .com zone). Step 2 (only if step 1 said
"not in zone"): GET /api/rdap?domain=xidorinus.com which HEADs
VeriSign's RDAP endpoint to confirm whether the domain is held at the
registry without active nameservers. Neither step logs your query.
