Overview

Zupport.chat is a privacy-first chat assistant for any website, with two layers of intelligence and a one-time price.

Last updated 2026-05-23

What Zupport.chat is

Zupport.chat is an embeddable chat assistant for websites. Your visitors ask questions in plain language and get answers from a model that already knows your product — because you uploaded the docs, the policies, the FAQs, and curated the questions you really care about getting right.

Two layers of intelligence

Every visitor message hits two layers in order:

  1. Scenarios — curated question/answer pairs you author in the app. Matched with a fast lexical search, so the visitor sees an exact answer in milliseconds.
  2. AI fallback — when no scenario matches well enough, the widget runs a small language model on the visitor's own device, grounded in your uploaded sources.

On phones the AI layer is skipped and only the scenarios are used (the LLM is too large to download on cellular hardware). That's why your scenarios matter — they are the entire mobile experience.

English only at launch
The on-device AI model is small enough to run in a browser, which means it doesn't yet have the strength to handle other languages reliably. If your visitors ask in another language, the assistant may produce poor or garbled answers. If you need multi-language support, hold off — we'd rather flag it up front than ship something half-baked.

Privacy posture

Nothing leaves the browser
The model runs locally via WebGPU or WASM. Your config, your scenarios, and your vector index are downloaded once and cached in IndexedDB. There is no conversation server, no tracking, and no cookies set by the widget.

Pricing

Zupport.chat is a one-time purchase, not a subscription. Pay once, embed forever, on as many pages as you like. See pricing for the current price.

Who it's for

  • Indie makers and small shops who want support without monthly bills.
  • Privacy-sensitive sites (legal, health-adjacent, EU SMBs) that can't ship visitor transcripts to a third party.
  • Anyone running a Shopify, WordPress, Webflow, or static site who can paste a two-line snippet.

What it isn't

  • It's not a livechat — there is no agent inbox.
  • It's not a CRM — it does not store conversation history server-side.
  • It's not a website builder — you bring the page, Zupport.chat adds the widget.
