Knocket

Knocket is the “free contact layer” from Tencent Cloud's real-time audio and video team: it puts a chat bubble on your site, gives an individual a conversational contact page, and funnels every message into one inbox. It is not an enterprise-grade support suite — it solves one thing: whether a visitor can reach a human right away.

Core capabilities

• Web widget: paste one line of script into WordPress, Shopify or a plain HTML site; the bubble supports a theme color, logo, welcome message and online hours, and switches to a lead-capture form when you are offline
• Contact page: publish a knocket.ai/<handle> page with 18 configurable blocks, and let AI generate the whole page from a single sentence
• Mobile SDK: the WebView SDK covers iOS, Android, React Native and Flutter, and shares the same conversation history as the web widget
• Unified inbox: messages from the web, apps, contact pages and email merge into the Inbox, and quoting a reply in Telegram takes you straight back to the visitor's conversation
• Optional AI Agent: connect a model with your own key and attach FAQ, URL-crawl and file-upload knowledge sources for automatic answers; when a handoff phrase is matched or confidence is too low, it suggests a handoff first and then confirms it to a human

Where it fits Independent developers, one-person companies and early-stage small teams: you already have a landing page, a Shopify or WordPress store or a portfolio site, you want a zero-cost inquiry entry point, and you are fine handling messages in Telegram. Mid-size or large support teams that need tickets, SLAs and agent scheduling should look elsewhere.

Why it stands out tawk.to is free but you have to babysit the dashboard, Intercom and Zendesk charge per seat, and Tidio locks key capabilities behind paid tiers. Knocket has no per-seat fee, no message cap and no credit card requirement; AI layers on top through your own key instead of being bundled into a plan, and the whole thing runs on Tencent's IM and RTC channels.

Editor's take This is the lowest-effort way in 2026 to get a conversation going: onboarding takes about a minute, running costs are close to zero, and AI turns your FAQ documents into 7×24 first-line answers. Once inquiry volume grows and you need team collaboration and permissions, migrating to a professional helpdesk costs you little.
