Full feature set

Every feature your support team needs — and your customers will notice

Built from real conversations. No feature bloat. No missing essentials.

AI-powered replies

Your AI agent reads your knowledge base and auto-answers common questions instantly — 24/7. When it can't help, it hands off to a real agent with full context intact.

Auto-repliesSmart handoffOffline capture

Real-time WebSocket messaging

Messages appear instantly — no polling, no refresh. Typing indicators for both visitor and agent, auto-scrolling, and a multi-line auto-resizing textarea that feels natural to use.

Voice message recording

Visitors can record and send voice notes directly in the chat. Built-in mic access with a live timer — no third-party app, no phone number required.

File attachments & image lightbox

Visitors can attach PDFs, documents, videos, and images. Photos render inline with lazy loading — click to expand in a full lightbox. Files get clean download links.

Markdown & rich text

Agents and AI can format replies with bold text, links, inline code, bullet points, and numbered lists. Messages look polished and scannable — not like a wall of plain text.

Built-in knowledge base tab

Visitors can switch to the Articles tab and search your help docs without leaving the widget. Category filtering, full article view, and a back button — self-service built right in.

CSAT surveys

After each conversation, Supplo shows a 5-star satisfaction survey with an optional comment field — once per session, so it never feels pushy. Track scores in the dashboard.

Mobile-first & iOS ready

Fully responsive with special handling for iOS keyboard behavior and viewport resizing. Touch-friendly buttons, proper safe-area insets, and smooth animations — even on a 4-year-old iPhone.

Pre-chat form & email capture

FAQ

Frequently asked questions

Everything you need to know before you add that script tag.

What is Supplo's live chat widget?
Supplo's live chat widget is an embeddable chat window you add to any website with one script tag. It gives visitors real-time messaging, AI-powered replies, voice messages, file sharing, and access to your knowledge base — all without leaving your site.
Does the widget reply automatically with AI?
Yes. Supplo's AI agent reads your knowledge base and answers common questions instantly. When it can't resolve something, it hands the conversation to a human agent — with the full conversation history already there.
What languages does the widget support?
9 languages: English, Spanish, French, German, Portuguese, Arabic (with RTL layout), Chinese, Hindi, and Japanese. The widget auto-detects the visitor's browser language — no configuration required.
Can visitors send voice messages?
Yes. Visitors can tap the mic icon, record a voice note with a live timer, and send it directly. Agents hear it in their inbox with a playback button — no third-party app or phone number needed.
What file types can be shared in chat?
Visitors and agents can share images (with inline rendering and click-to-expand lightbox), PDFs, documents, and videos. Non-image files appear as clean download links inside the conversation.
What happens when no agents are online?
Supplo captures the message and sends an instant auto-reply to let the visitor know their message was received. You'll see it waiting in your shared inbox — and can reply when you're back, with full conversation context.
Can I customize the widget to match my brand?
Absolutely. From the Supplo dashboard, you can change the brand color, business name, logo, and welcome message. No coding required — changes apply instantly across your whole site.
Does Supplo collect customer satisfaction ratings?
Yes. After each resolved conversation, Supplo shows a 5-star CSAT rating prompt with an optional comment field. It appears once per session. Scores are tracked in your analytics dashboard.
Does the widget work on mobile and tablets?
Yes. Fully responsive with special handling for iOS keyboard push-up, viewport resizing, and safe-area insets. Buttons are touch-friendly and the layout adapts cleanly to any screen size.
Is there a built-in knowledge base?
Yes. The widget has a tabbed interface — Chat and Articles. Visitors can search your help articles, filter by category, and read full articles directly inside the widget without opening a new tab.
