Quick Start Example

Basic Inline AI Assist with Summarize Button

import { InlineAIAssist } from '@syncfusion/ej2-interactive-chat';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize Inline AI Assist
let inlineAssist: InlineAIAssist = new InlineAIAssist({
    relateTo: '#summarizeBtn',
    placeholder: 'Ask AI to help...',
    promptRequest: (args) => {
        // Connect to your AI service
        setTimeout(() => {
            let response = 'AI-generated summary of the content...';
            inlineAssist.addResponse(response);
        }, 1000);
    },
    responseSettings: {
        itemSelect: (args) => {
            if (args.command.label === 'Accept') {
                // Apply the AI response to your content
                document.getElementById('content').innerHTML = args.response;
                inlineAssist.hidePopup();
            } else if (args.command.label === 'Discard') {
                // Reject the response
                inlineAssist.hidePopup();
            }
        }
    }
});

inlineAssist.appendTo('#inlineAssist');

// Show popup on button click
document.getElementById('summarizeBtn').addEventListener('click', () => {
    inlineAssist.showPopup();
});

<button id="summarizeBtn" class="e-btn e-primary">Summarize</button>
<div id="content" contenteditable="true">
    Your content here...
</div>
<div id="inlineAssist"></div>

Common Patterns

Pattern 1: Quick Command Actions

let inlineAssist: InlineAIAssist = new InlineAIAssist({
    relateTo: '#improveBtn',
    commandSettings: {
        commands: [
            { label: 'Summarize', prompt: 'Summarize this content', iconCss: 'e-icons e-collapse-2' },
            { label: 'Shorten', prompt: 'Make this shorter', iconCss: 'e-icons e-shorten' },
            { label: 'Translate', prompt: 'Translate to Spanish', iconCss: 'e-icons e-translate' },
            { label: 'Make Professional', prompt: 'Rewrite professionally', iconCss: 'e-icons e-elaborate' }
        ]
    },
    promptRequest: (args) => {
        // Handle different commands
        callAIService(args.prompt);
    }
});

Pattern 2: Accept/Reject Workflow

let inlineAssist: InlineAIAssist = new InlineAIAssist({
    relateTo: '#editor',
    promptRequest: (args) => {
        // Get AI response
        getAIResponse(args.prompt).then(response => {
            inlineAssist.addResponse(response);
        });
    },
    responseSettings: {
        itemSelect: (args) => {
            if (args.command.label === 'Accept') {
                // Apply changes
                applyChanges(inlineAssist.prompts[inlineAssist.prompts.length - 1].response);
                inlineAssist.hidePopup();
            } else if (args.command.label === 'Discard') {
                // Discard changes
                inlineAssist.hidePopup();
            }
        }
    }
});

Pattern 3: Streaming Responses

let inlineAssist: InlineAIAssist = new InlineAIAssist({
    relateTo: '#generateBtn',
    enableStreaming: true,
    promptRequest: (args) => {
        // Stream response from AI service
        streamAIResponse(args.prompt, (chunk) => {
            inlineAssist.addResponse(chunk);
        });
    }
});

Pattern 4: Custom Editor Template

let inlineAssist: InlineAIAssist = new InlineAIAssist({
    relateTo: '#customBtn',
    editorTemplate: () => {
        return `
            <div class="custom-editor">
                <textarea id="customPrompt" placeholder="Type your request..."></textarea>
                <button id="sendBtn" class="e-btn">Generate</button>
            </div>
        `;
    }
});

document.addEventListener('click', (e) => {
    if (e.target.id === 'sendBtn') {
        const textarea = document.getElementById('customPrompt');
        inlineAssist.executePrompt(textarea.value);
    }
});
