The public communication stack for AI-first businesses

Your customers don’t all speak the same language. Now your business does.

ComStack is the communication layer for your business: one intelligent brain that answers every customer — on the phone, over WhatsApp, on your website, or in person — in their own language, around the clock. The after-hours call that used to ring out, the message in a language nobody on your team speaks, the visitor about to leave without making contact — every one of them gets answered now. You set it up once and keep it current just by talking to it. No call centre, no chatbot bolted onto your website, no developer.

Speaks every language, natively. A customer can call in Arabic, message on WhatsApp in Norwegian, and read your website in Spanish — and get the same correct answers from the same source. Translation isn’t bolted on channel by channel; it lives in the brain, so nothing drifts and nothing is lost in handoff. For any business serving international or multilingual clients, that’s the difference between a customer served and a customer gone.

One brain, every channel

You structure what your business knows once. Every channel draws from it, so the answer is the same whether a customer calls, messages, or walks in:

Phone — answers any number in any language, handles questions, walks callers through bookings and forms, and texts a link at the end of the call to finish the booking, payment, or sign-up.
WhatsApp — voice and chat in one thread, with tappable cards for choosing options and completing form-like steps while talking live.
Website — a page where visitors talk, type, or tap to get answers in their language, plus a structured site that AI assistants can read and act on.
In person — the same assistant on a reception kiosk, or through a QR code that opens it on the visitor’s own phone — built for walk-ins and front desks.
Email — (coming) drafted replies built from the same knowledge that powers every other channel.

Tell it once; it knows everywhere

ComStack is headless. Everything your business knows lives in one brain, and every channel, page, and the live assistant all draw from it. There’s no CMS to log into and no developer in the loop — update the brain once and the change lands across every channel and every language at the same moment. Several ways to keep it current, mix them freely:

Just say it out loud. Open any page on your own site and talk to it. “Change Saturday hours to 9 to 2.” “Add a paragraph about the new airport pickup service.” “Drop the price on the deluxe room to 180.” The assistant makes the edit while you watch, shows you the result, and the moment you approve it goes live — translated into every language automatically. No forms, no fields, no rebuild. Editing your website becomes a conversation. Prefer to type? Edit-in-place on any page — same instant, no-CMS publish.
Edit from your AI assistant. Connect ComStack to Claude, ChatGPT, or any MCP-capable agent and ask it to add a service, fix a price, or write a new page — it updates the brain directly. Every public page can be optimized for humans, for AI agents, or both, and pages can be pure knowledge the live assistant draws on without ever being shown to a visitor.
Automate it. Point your favourite agent at a recurring task and let it keep the brain in sync with the rest of your business. A scheduled job in Claude or ChatGPT can pull your opening hours from Google Maps each morning and update them everywhere, fold in a new price list, or refresh seasonal content on a schedule. Rich APIs and the MCP server make your business knowledge programmable — so it maintains itself.
Clip from anywhere. Found a supplier’s page, a partner’s listing, or content on your old website you want to bring over? The ComStack Chrome extension grabs the page, turns it into clean structured content with AI, and drops it into your brain as a draft to review — no copy-paste, no reformatting.

Forms that talk back

Bookings, guest intake, lead qualification, rental applications — the assistant walks each customer through it as a conversation, reading every question aloud and letting them answer by voice or tap, in their own language. Answers are captured, validated, and handed straight to your systems when the form is done. It works the same on a phone call, in WhatsApp, on your website, or at a kiosk. It’s everything a web form does, without the form — and far more likely to be finished.

Your data is yours

No lock-in, ever. Everything your business knows is stored as clean, well-organized Markdown that you own outright. Sync it to your own private GitHub repository and keep a full copy under your control — readable, portable, and yours to take anywhere. Headless by design means your content is never trapped inside someone else’s CMS.

The same structure that lets your business answer in any language also makes it readable to AI assistants. When someone asks ChatGPT, Claude, or Gemini for a recommendation in your category, your business has the opportunity to appear — and the assistant can hand the customer a ready-made link straight into a booking or sign-up.
