Building an AI chatbot in Angular yourself

An AI chatbot is more than a chat window and a call to a model API. Here’s what it takes to run one well — and what you can skip.

What you’d build and keep running

A model and its bill

Pick a model, handle rate limits and watch token costs grow with traffic.

Your content as answers

Crawl the site, split and embed it, and keep the index in sync when pages change.

The chat UI

Bubbles, streaming replies, typing dots, mobile layout and accessibility on every page.

Conversation memory

Keep each visitor’s thread and feed the right context back within the token budget.

Guardrails

Keep answers on topic, avoid made-up facts and decide what it must never say.

Leads and handoff

Forms in the chat, consent, and passing the right conversations to a person.

Transcripts and analytics

Store chats, email them to the team and see what visitors ask about.

Upkeep

Model updates, prompt tuning, security fixes — and someone on call when it breaks.

With Elfsight: one component

Create and train the agent in the Elfsight editor, then render one component. Answers, leads and settings live in your dashboard — no redeploy to change them.
Angular
<app-ai-chatbot id="YOUR-ID" />

  • Learns from your website automatically

  • Lead forms and human handoff built in

  • Chat history, transcripts and analytics

  • Floating or embedded, styled in the editor

  • Free plan, no credit card

Integration

Add the AI chatbot to Angular

The component

  • Standalone component. Import it where you need it — no module to register.

  • SSR-safe. It touches the document through Angular’s DOCUMENT token.

  • Floating or embedded. Put a floating chat in the app component once; an embedded one where it should show.

Angular
// ai-chatbot.component.ts
import { Component, Input, OnInit, Inject } from "@angular/core";
import { DOCUMENT } from "@angular/common";

const SRC = "https://elfsightcdn.com/platform.js";

@Component({
  selector: "app-ai-chatbot",
  standalone: true,
  template: `<div [class]="'elfsight-app-' + id" data-elfsight-app-lazy></div>`,
})
export class AiChatbotComponent implements OnInit {
  @Input({ required: true }) id!: string;
  constructor(@Inject(DOCUMENT) private doc: Document) {}

  ngOnInit() {
    if (this.doc.querySelector(`script[src="${SRC}"]`)) return;
    const s = this.doc.createElement("script");
    s.src = SRC;
    s.async = true;
    this.doc.body.appendChild(s);
  }
}
Out of the box

What the agent does with no code of yours

Builds from your website

Scans your website to understand your business, products, services, and content, then turns it into an AI agent automatically.

Creates a knowledge base

Turns your website content into accurate AI answers automatically.

Shapes a personality

Creates a name, icon, role, and tone of voice based on your business.

Prepares the first interaction

Generates welcome messages and quick replies designed for your visitors and business goals.

Equips with the right skills

Adds lead capture, action buttons, and other capabilities automatically based on your business.

Learns from conversations

Detects missing knowledge and helps improve future conversations over time.
