CTX-RSVP collects guest responses via AI voice calls in 10 Indian languages and WhatsApp — so your team focuses on the event, not the phone.
A Hyderabad wedding with 600 guests. The family allocated 3 people to make calls for 10 days. They reached 400. The rest got a generic WhatsApp. 140 people showed up who weren't expected. The hotel ran out of rooms. The transport coordinator had 20 unknown pickups the morning of the event.
This is not an edge case — it's the default outcome when RSVP collection is done manually at Indian event scale. CTX-RSVP replaces the chaos with an automated, multi-channel outreach engine that collects structured responses from every guest on your list.
Vapi + Sarvam AI conducts natural phone conversations with your guests — in Hindi, Telugu, Tamil, Malayalam, Kannada, Bengali, Marathi, Gujarati, Punjabi, or English. The AI transcribes every response and records a structured RSVP: attending, headcount, dietary needs, and travel plans.

A structured WhatsApp conversation collects attendance, meal preference, headcount, and travel details in a natural back-and-forth. Guests don't need to download anything. You get a clean, structured response — not a free-text message to parse.

Automated · Responds instantly
Not every guest will respond on WhatsApp or answer a voice call. CTX-RSVP hosts a branded RSVP web page — accessible via a magic link — for guests who prefer to fill in a form on their own time.

Configure multi-step reminder sequences that run automatically — WhatsApp first, then voice call, then human-caller queue for VIPs. Non-responsive guests are escalated based on rules you set, not when a coordinator remembers to follow up.
The coordinator dashboard shows live counts by RSVP status, channel, function, and day. Dietary counts, travel detail summary, and per-invitee history — all in one view. Export to CSV at any time.

CTX-RSVP uses a channel escalation ladder: WhatsApp first, then an AI voice call, then a human-caller queue for VIPs and hard-to-reach guests. Guests who don't use WhatsApp at all are served by voice or by a human caller — no guest falls through a single failed channel.
On the Growth plan: all languages supported by Sarvam AI — Hindi, Telugu, Tamil, Malayalam, Kannada, Bengali, Marathi, Gujarati, Punjabi, and English. Scale adds ElevenLabs voices for custom persona and cadence. Starter covers English and Hindi.
