Meet Yen.Your jewelry-trained AI.
Yen is the K99 AI assistant trained on jewelry — not on the open internet. She writes product descriptions, drafts customer replies, translates your storefront into 24 languages, and spots trends before they break. Metered, audited, and always under your brand.
Eight capabilities. One assistant.
Every Yen feature is built around a real jeweler workflow — not generic ChatGPT prompts retrofitted onto your data.
Writes product descriptions
Yen reads the SKU, the metal, the stones, and the certification — then writes copy that reads like a human jeweler wrote it. SEO-grade, on-brand, in any of 24 languages.
Drafts customer replies
Yen reads the full CRM context — past orders, ring size, anniversary date, last interaction — and drafts a reply that sounds like you wrote it. Approve, tweak, or send as-is.
Translates your whole storefront
One click translates your entire catalog, blog, emails, and policy pages into any of 24 languages — and keeps the brand voice intact. No Google-Translate stiffness.
Writes marketing campaigns
Tell Yen what you want to promote and who to send it to. She drafts the subject line, the email, and the SMS — segmented by your CRM tags, your spend tiers, your geography.
Spots trends before they break
Yen watches your search queries, abandoned carts, and Instagram saves — and tells you which SKUs are about to spike. Restock the right metal in the right alloy before the rush.
Auto-tags & categorises
Drop a CSV of legacy SKUs and Yen tags every one — by metal, by stone, by occasion, by style. What used to take a merchandiser a week takes 12 minutes.
Generates alt text & SEO meta
Every product image gets accessible alt text. Every product page gets a unique meta title and description. Yen does it once, you ship the storefront, Google ranks it.
Answers your team's questions
"Yen, what's our return policy on engraved pieces?" "What's the margin on the Marlowe collection?" "Who hasn't ordered in 18 months and lives within 50 miles of the showroom?" Yen knows.
How Yen learns your brand.
Off-the-shelf AI sounds like a chatbot. Yen sounds like you — because she trains on you.
Yen meets your brand
On day one, Yen reads your existing copy, your past customer emails, your brand voice guidelines. She learns to write like you — not like a chatbot.
She lives in your admin
No new app to learn. Yen surfaces in product pages, the CRM inbox, the email composer, the bulk-edit screen — wherever you'd actually use her.
You review, she ships
Every Yen-generated draft is held for your one-click approval before it goes live. Or set auto-publish for low-stakes items like alt text.
She gets smarter every week
Yen learns from your edits. The descriptions you tweak teach her your tone. By month three, you'll edit less than 10% of what she writes.
The grown-up part of AI.
Most AI tools bill you a flat monthly fee for "unlimited" — then mysteriously go down when you actually use them. Yen is the opposite. Pay for what you use, see exactly what you used, cap it when you want to.
Metered & transparent
Every Yen request is logged with token count and cost. See exactly what you've used this month — by team member, by feature, by language.
Hard caps, no surprises
Set monthly spend limits per workspace. When you hit your cap, Yen pauses cleanly — no overage bills, no auto-charges, no trapped accounts.
Bring your own key
Power users plug in their own OpenAI or Anthropic key and bypass K99 metering entirely. Your token, your bill, your control.
Always-on audit log
Every prompt and response is recorded against a user, a tenant, and a timestamp. Compliance teams can search the full history.
Domain-bound, not internet-bound
Yen is grounded in YOUR storefront, YOUR CRM, YOUR catalog. She doesn't hallucinate from random web pages — she answers from your data.
GPT-4o + Claude 3.5
Yen uses the right model for the job — GPT-4o for creative copy, Claude 3.5 for long-context reasoning, smaller models for tagging at scale.
Generic AI vs. Yen.
Why a jewelry-trained assistant ships work that a generic chatbot never will.
