Hi! Are you open today?

Yes — we're open today till 8pm 🙂 Anything you'd like us to set aside for you?

Do you still have the chocolate fudge cake?

Two slices left! Want me to hold one under your name? Just send it through and we'll have it ready at the counter.

Live in three simple steps.

You don't need a technical team. If you can send a WhatsApp message and upload a file, you can run Sello.

Connect your WhatsApp number

Plug in your WhatsApp Business number. We walk you through the one-time setup — no developer required.

Upload what you want it to know

Upload your menu, prices, opening hours, return rules, and FAQs. Anything you would write down for a new staff member. Sello learns it all in a few minutes.

Go live and watch it work

Sello starts replying to your customers right away — day and night, using only what you've uploaded. Update your documents anytime and it keeps up.

Built for businesses like yours.

Anywhere customers ask the same questions on WhatsApp every day.

Today, Sello answers questions from what you upload. Customer records and orders are on the way.

Online stores
Clinics & salons

Everything you need to keep customers happy on WhatsApp.

Built for small teams and busy owners — not engineers.

Trained on your business

Upload your menu, prices, opening hours, return rules, and FAQs. Sello answers from what you wrote, not made-up details.

Sounds like you

Set the tone — friendly, formal, cheeky. Sello stays on-brand in every reply, in your customers' language.

Set up in minutes, not weeks

Connect your WhatsApp Business number, drop in a few documents, and you're live the same day. No coding, no IT team.

Predictable monthly bill

Pick a plan that fits your size. Sello warns you before you hit your limit, so there are no surprise charges at the end of the month.

Your customer data stays yours

Conversations are private to your business and locked to your account. Encrypted in transit and at rest. Delete your documents anytime.

Also on your website (Pro plan)

Already growing? Pro plan users can put Sello on their own website too. Add one line of code. The same assistant answers your website visitors, with the same answers.
