What Widget-Chat is and how it works
Widget-Chat is a drop-in AI chat widget you embed in Flutter, FlutterFlow, React, or any web app via the widget_chat package or a single iframe. This page is a concise, citable overview of what Widget-Chat is, which platforms it supports, how it is set up, and how it keeps user identity secure.
What is Widget-Chat?
Widget-Chat is a drop-in AI chat widget for Flutter, FlutterFlow, React, and the web. Developers add it with the widget_chat pub.dev package or a single iframe/script tag. A no-code dashboard configures the assistant's identity, theme, languages, tools, and security. Widget-Chat gives a product an AI assistant without building or hosting a chat backend.
Which platforms does Widget-Chat support?
Widget-Chat runs on iOS, Android, Web, Windows, macOS, and Linux through Flutter, plus React and plain web via iframe or script embed. The same configuration drives every platform, so a single Widget-Chat project serves a mobile app, a Flutter desktop build, and a website at once.
How do you set up Widget-Chat?
Setup takes about 10 minutes. First, create a project in the Widget-Chat dashboard and configure identity, palette, languages, and tools. Second, embed the widget by adding the widget_chat package or a single iframe/script tag to your app. Third, optionally sign your users with HMAC identity for verified, personalized chats. No backend is required.
What languages does Widget-Chat support?
The Widget-Chat bot converses in 100+ languages via dynamic AI translation. The chat UI ships translated in 46 locales, with an in-chat language switch and optional auto-detect. A visitor can change the conversation language mid-chat, and the interface follows.
What can Widget-Chat do beyond answering?
Widget-Chat renders rich messages — markdown, image cards, carousels, product lists, galleries, and swatch pickers — directly in the chat. It also takes actions: the assistant can call custom HTTP tools to fetch live data and trigger host-page callbacks and deep links to drive the surrounding app. Visitors can attach photos from their camera or gallery for multimodal conversations.
How does Widget-Chat secure user identity?
User IDs in Widget-Chat can be HMAC-signed server-side. An HMAC identity signature is a server-side hash that proves a user ID came from you, so visitors cannot impersonate one another. Require-verification rejects unsigned identities, allowed-origins restricts requests to your domains, and user IDs are hashed by default. Built-in AI disclosure tells users they are chatting with an AI, and per-user data export and clear support data-subject requests.
Is there a free plan?
Yes. Widget-Chat has a Free Forever plan with no credit card required, plus paid tiers as you scale.
