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.
five (Pentium = fifth-generation Intel CPU)
Lexicon Branding canonical case — Pentium named to differentiate 5th-gen Intel CPU from the '586' that competitors could clone. Placek talks about it on Lenny's pod.
e.g. Pentium · Pentagon
Greek root
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

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
Pairs pentkaddu with classical suffixes (-ex, -ius, -ium, -on), morphemes from the bank (ver-, lex-, pro-), and vowel mutations — then bloom-checks every candidate against the live .com zone file. Up to 400 candidates per click; only the available ones land here.

First-letter feeling
P-onset: Punchy, popping, percussive
P pops. Plays well with concrete object names — Pepsi, Pixar, PowerBook, Pentium. Lexicon canonical: PowerBook = compound, Pentium = morpheme + suffix.
Examples: Pepsi · Pixar · PowerBook · Pentium · Polaroid · Pinterest
Morpheme breakdown — 1 root detected in pentkaddu
pent · Greek · five (Pentium = fifth-generation Intel CPU)
from pente, 'five'

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