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.
meditation, calm clarity
Z is Placek-noisy + cross-cultural calm semantic. Tension between sound and meaning.
e.g. Zendesk · Zen · Zenly
Japanese (via Chinese chán via Sanskrit dhyāna) root
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
Confident, open, expansive
A opens the mouth wide. Brands starting with A feel approachable and confident — Amazon, Apple, Asana, Adobe, Atlassian. The open vowel makes a name feel inclusive and platform-like.
e.g. Amazon · Apple · Asana · Adobe · Atlassian
Sharp, crisp, bright
K is the bouba/kiki experiment's spiky letter. Kodak, Krispy, Kindle. Pairs well with the bouba/kiki rule (cross-cultural — K reads as 'pointy' across languages).
e.g. Kodak · Kindle · Krispy Kreme · Klarna · Klaviyo
Confident, open, expansive
A opens the mouth wide. Brands starting with A feel approachable and confident — Amazon, Apple, Asana, Adobe, Atlassian. The open vowel makes a name feel inclusive and platform-like.
e.g. Amazon · Apple · Asana · Adobe · Atlassian
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
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

How we check. Step 1 (client-side): POST /api/check
with zennakasu.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=zennakasu.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.
