Questions, answered

Everything you need to know before you start.

Do I need a new WhatsApp number?

You can connect an eligible WhatsApp Business number through Meta's Embedded Signup. Meta will show whether your current number can be connected or whether it needs to be migrated or registered first.

Will it really understand Tamil and Tanglish?

Yes. Slot Reply replies fluently in English, Tamil and Tanglish (Tamil typed in English letters) — it matches whatever language your customer writes in.

What happens when the bot can't handle something?

It hands the chat over to you and sends an alert. You can jump in from the dashboard at any time, and the bot steps back until you're done.

Is my data private?

Every business gets its own isolated database — your conversations are never mixed with anyone else's. You can export or delete your data whenever you like.

Can I cancel anytime?

Absolutely. There are no lock-in contracts or setup fees. Upgrade, downgrade or cancel from your dashboard whenever you want.

Is Slot Reply part of WhatsApp or Meta?

No. Slot Reply is an independent service operated by Ondravan Private Limited. WhatsApp is a trademark of Meta Platforms, Inc., and Slot Reply connects through Meta's official business APIs.

Stop letting customers wait.

Create your workspace, connect an eligible WhatsApp Business account and review your automation before it goes live.
