Three steps. No agencies,
no “book a call”.
Official Mercado Libre authorization. Five minutes, on your own, right from the browser.
Catalog, variants, stock and your private notes. Read-only: it never touches your listings.
Dashboard and phone. “Take over” in one tap; anything iffy comes to you with context.
Question, answer,
posted. Nine seconds.
Every answer is grounded in a real product from your catalog — with variant and stock — and posts straight to Mercado Libre. If it can't verify something, it doesn't make it up: it escalates to you.
- Grounded in your catalog, never “according to the manufacturer”
- Your voice: warm, yours, no “Dear user”
- “Take over” in one tap, from your phone too
Speed is ranking.
Your response time feeds your reputation, and your reputation decides who shows up on top. A question left waiting for hours is a sale already made — on someone else's listing.
The easy ones now answer themselves.
The ones that reach you decide the sale.
Mercado Libre's AI instantly answers what's on the listing — size, color, material. What lands in your inbox is exactly what it can't: real stock, shipping, invoicing, discounts, “can you hold it for me?”. And each one sits public and unanswered — in front of every buyer — until you reply. Hej-Hej answers them with your catalog, your policies and your voice.
Your whole ML business, on one calm screen.
What the agent answered, what it escalated to you, and what you sold. Conversations, catalog, customers and orders — clear and quiet.
Sellers who no longer leave questions unanswered
“I used to answer questions at 11 at night. Now I check the dashboard with my morning coffee.”
“With 900 listings it was impossible. The agent answers with the exact size and stock, without making things up.”
“My response time went from hours to seconds and it shows in the ranking. Views climbed on their own.”
Public pricing, 60-day guarantee.
No quotes, no calls — you pick, you connect, you're set.
Frequently asked questions
(we answer yours fast too)
Doesn't Mercado Libre already answer with AI?
It does — and it does it well for what's on the listing: size, color, material. But the buyer can still choose to ask you, and everything the listing doesn't know — real stock, shipping, invoices, discounts — keeps reaching you and stays public until someone answers. Those are the ones Hej-Hej handles.
Do you write or edit my listings?
Never. We only read your catalog and answer questions. We don't request permissions to create or edit listings, and your tokens are stored encrypted.
What happens when the agent doesn't know something?
It doesn't make things up: it escalates the conversation to you with context and lets you know. You reply from the dashboard or your phone.
What languages does it answer in?
Spanish and Portuguese, in your store's voice. The dashboard is in Spanish, English and Portuguese.
What happens if I run out of answers for the month?
You decide: keep answering at an extra cost, or queue the questions to answer yourself. We always keep you posted.
When is WhatsApp coming?
We're focused on being the best on Mercado Libre first. WhatsApp and Instagram come later — same agent, same pricing.
