SDKs

One published Flutter widget SDK, plus a REST API and OpenAPI spec you can call from any language.

AskAIs is protocol-first: one OpenAPI 3.1 spec, one WebSocket protocol, and HMAC-signed webhooks. You can call the API from any language and render your own UI. Today we publish one packaged UI SDK, the native Flutter widget.

The published SDK: Flutter widget

The one SDK we ship today lives in sdks/flutter-widget/. It is a full, themeable chat UI that talks to the REST API and WebSocket for you. Add it to yourpubspec.yaml as a local package:

# pubspec.yaml
dependencies:
  singchat_widget:
    path: ../sdks/flutter-widget

iOS and Android

There is no separate native SDK for iOS or Android. Two supported paths:

WebView (recommended), load the web widget from /api/widget-embed. It is the full-feature widget and auto-updates, so you never ship an app release just to get new chat features.
REST API, call the API directly and render your own native UI.

There are no ready-made SwiftUI or Jetpack Compose chat views. You either embed the WebView or build the UI yourself on top of the API.

Any other language: call the REST API

We do not ship pre-built clients for Python, Go, Rust, C#, Java, PHP, Ruby, or similar, and there are no official React Native, Unity, or Unreal SDKs. Instead there is a public REST API with an OpenAPI 3.1 spec, so you can call it over plain HTTP or generate your own client:

OpenAPI: GET /api/v1/openapi.json
WebSocket: see Web widget docs for event JSON

Generate a client for the language you want with openapi-generator:

# generate a client from the public spec
npx @openapitools/openapi-generator-cli generate \
  -i https://singchat.org/api/v1/openapi.json \
  -g python \
  -o ./singchat-client

What AskAIs ships

Beyond the widget, these product capabilities are live today:

Unified inbox across the web widget, Telegram, and WhatsApp, with an X (Twitter) slot ready.
Platform-hosted AI: no API key required, token-metered with auto-topup and human fallback, or bring your own key.
AI Training Center: crawl your site, upload PDF, Word, or DOCX files, add Q&A pairs from a CSV, and rehearse in a pre-launch Playground.
50-language help center for self-serve articles and FAQ.
Full white-label branding across every customer-facing surface.
Anti-blocking multi-domain delivery for the widget.

Quick examples

Flutter widget

import 'package:singchat_widget/singchat_widget.dart';

// mount the themeable chat UI
SingChatWidget(
  appId: 'ws_abc123',
  user: SingChatUser(
    externalId: 'user_42',
    email: 'ada@example.com',
  ),
)

iOS WebView

import WebKit

let webView = WKWebView(frame: view.bounds)
let url = URL(string: "https://singchat.org/api/widget-embed?appId=ws_abc123")!
webView.load(URLRequest(url: url))
view.addSubview(webView)

Android WebView

val webView = WebView(this)
webView.settings.javaScriptEnabled = true
webView.loadUrl("https://singchat.org/api/widget-embed?appId=ws_abc123")
setContentView(webView)

Raw curl

# identify against the REST API (any language, no library)
curl https://singchat.org/api/v1/auth/identify \
  -H "Content-Type: application/json" \
  -d '{ "appId": "ws_abc123", "email": "ada@example.com" }'
