MetaHow it works
From setup to fully autonomous — in under an hour.
01Connect your channels
One-click Gmail OAuth and a guided WhatsApp Business API setup. Your inbox is live and monitored in under 10 minutes.
Upload your knowledge
Price lists, service catalogues, FAQs, and policies. RheXa ingests your documents and replies only from verified data — never guesses.
AI takes the wheel
Every message classified, replied to in your voice, escalated when it matters, and followed up with prospects who didn't convert — all automatic.
Everything included
One platform. Every channel. Total control.
Not a chatbot. Not a template engine. A genuine AI agent that understands context, knows your business, and escalates when it matters.
WhatsApp and email. One dashboard.
Every conversation in real time, colour-coded by status. Green handled, yellow waiting, red needs you. Take over any thread instantly — AI picks back up when you step away.
AI that knows your business cold.
Upload PDFs, catalogues, or URLs. AI replies from your verified data only — never fabricates, never guesses.
Knows when to stop.
Confidence below 0.85? Held for your approval. Legal threats? Always escalated. No exceptions.
Any language, automatically.
Customer writes in Arabic or Spanish — AI detects and replies in the same language. Zero setup required.
Converts prospects who go quiet.
No reply in 48h? AI follows up naturally. Runs itself. You never have to remember to chase anyone again.
Sounds exactly like you.
Paste 5–10 of your past replies. RheXa learns your exact tone — formal, casual, warm, direct — and mirrors it on every single message. Your customers can't tell it's AI.
