Channels — reach customers everywhere
One brain. Every way in.
Phone. WhatsApp. Your website. The front desk. And, increasingly, an AI assistant a customer asked instead of visiting you at all. Bolt a separate tool onto each and the answers drift apart. ComStack is one assistant that speaks for your business on all of them — any language, one source, around the clock. Correct something once; it’s correct everywhere, instantly.
Phone
Your number, answered in any language, day or night. It books, takes details, and texts a link to finish on the customer’s phone — or hands a live caller to your team with the full context already gathered. No voicemail. No language barrier. No missed booking.
Where your international customers already are. They talk or type; the assistant answers with tappable cards and carries them from question to confirmed booking without leaving the thread — in their language.
Be the answer AI gives
Customers don’t open ten tabs anymore. They ask ChatGPT, Claude, or Gemini — and the assistant answers for them. ComStack makes your business the source those assistants read, trust, and recommend, then drops the customer a ready-made link straight into a booking. This isn’t a website hoping to get found. It’s built for the assistants that now do the finding — and the same brain turns your own site into something visitors talk to, not just scroll.
In person
A reception kiosk for walk-ins, or a QR code on a table or door that opens the assistant on the customer’s own phone. Questions answered and check-ins done in their language, no staff standing by. Made for hotels, tourism desks, and front desks that never stop.
Coming. Replies drafted from the same brain, so an email gets the same answer as a call.
One source, zero drift
Many channels, one truth. The price on the phone, the slot on WhatsApp, the answer from an AI — identical, because they all read from one source. No stale pages. No contradicting yourself. Change it once; everywhere catches up at the same moment.
