Trend Chat is a powerful tool that enables users to track, analyze, and interact with trends from various online communities. Whether you're a business owner, marketer, or enthusiast looking to stay ahead of the curve, Trend Chat provides real-time insights into the conversations that matter most to your industry.
By leveraging BrightData for web scraping and AI for generative analysis, Trend Chat allows users to gather relevant data, analyze it for actionable insights, and chat with these trends to make informed decisions.
What I Built
Trend Chat is designed to solve the problem of information overload in today’s fast-paced digital world. It empowers users to track trends across niche online communities, scrape data from various websites, analyze that data to uncover key insights, and interact with those insights via a simple chat interface.
Key Features:
- Web Scraping: Automatically gather data from websites, primarily Reddit, based on user requests, leveraging BrightData Web Scraping Browser for huge dynamic websites like reddit.
- Data Analysis: Analyze scraped data to uncover patterns, trends, and actionable insights based off named entity extraction for commonalities in a season
- Chat Interface: Chat with the collected insights, allowing users to ask questions and get responses based on the data.
- AI-Powered Insights: Use AI models to generate real-time analysis, recommendations, and insights from trends.

How I Used Bright Data
Bright Data plays a crucial role in Trend Chat by providing the web scraping infrastructure that powers the collection of data from Reddit. Using the Bright Data Scraping Browser, I can:
- Gather Real-Time Data: Bright Data allows me to scrape Reddit data based on specific user inputs, ensuring that the data is always up-to-date.
- Access Diverse Data: Scrape content from subreddits, including forum posts, comments, and articles, based on a wide range of topics and keywords.
- Customize Scraping: The flexibility of Bright Data enables me to tailor the scraping process to suit specific needs, such as collecting posts and discussions from specific subreddits related to emerging trends.
This integration with Bright Data is what enables Trend Chat to provide real-time, dynamic insights from niche online communities.
Sample Code for Scraping Reddit Data using Bright Data API (Typescript)
// Function to generate the Reddit search URL based on the keyword
function generateRedditSearchUrl(keyword: string): string {
const encodedKeyword = encodeURIComponent(keyword);
return `https://www.reddit.com/search/?q=${encodedKeyword}`;
}
// Function to scrape Reddit posts based on a search URL
async function scrapeRedditPosts(searchUrl: string) {
const browser = await puppeteer.connect({
browserWSEndpoint: "puppeteer ndpoint from your scraping browser",
});
console.log("Connected to browser...");
const page = await browser.newPage();
await page.goto(searchUrl, { waitUntil: 'domcontentloaded' });
console.log("Navigated to Reddit search page");
await page.waitForSelector('div[data-testid="post-container"]', { timeout: 30000 });
const posts = await extractPostData(page);
await browser.close();
return posts;
}
// Function to extract post data from the Reddit search results page
async function extractPostData(page: puppeteer.Page) {
return await page.evaluate(() => {
const postElements = document.querySelectorAll('div[data-testid="post-container"]');
const posts = [];
postElements.forEach((postElement: Element) => {
const title = postElement.querySelector('h3')?.innerText;
const author = postElement.querySelector('[data-testid="post_author_link"]')?.innerText;
const upvotes = postElement.querySelector('[data-click-id="upvote"]')?.textContent;
const comments = postElement.querySelector('[data-click-id="comments"]')?.textContent;
posts.push({ title, author, upvotes, comments });
});
return posts;
});
}
AI for Named Entity Extraction
To extract valuable information from the scraped posts, Trend Chat uses AI models powered by the Transformers library for Named Entity Recognition (NER). This allows us to identify and extract key entities such as people, places, organizations, or any other relevant keywords from the data.
We use a pre-trained NER model from the Hugging Face Transformers library to analyze Reddit posts and identify entities like product names, trending topics, and more.
Sample Code for Named Entity Recognition (NER) using Transformers (Typescript)
import { pipeline } from 'transformers'; // Importing the HuggingFace pipeline for NER
const nerModel = pipeline('ner', 'dbmdz/bert-large-cased-finetuned-conll03-english'); // Pre-trained NER model
const extractEntities = async (text: string) => {
const entities = await nerModel(text);
return entities;
};
const sampleText = "I love programming in Python and recently explored Next.js for building dynamic web apps!";
extractEntities(sampleText).then(entities => {
console.log('Extracted Entities:', entities);
}).catch(error => console.error('Error extracting entities:', error));
The extracted entities can be further analyzed to find trends or insights such as frequent mentions of specific topics, brand names, or even upcoming technologies.
Combining the Two
async function main() {
const prompt = "Tell me about recent discussions on code editors and their features, especially AI-powered editors"; // Example prompt
// Step 1: Extract keywords
const keywords = await extractEntities(prompt);
console.log("Extracted Keywords: ", keywords);
// Step 2: Search Reddit for the extracted keyword(s)
for (const keyword of keywords) {
const searchUrl = generateRedditSearchUrl(keyword);
console.log(`Searching for "${keyword}" on Reddit...`);
// Step 3: Scrape the posts for the keyword
const posts = await scrapeRedditPosts(searchUrl);
console.log(`Found ${posts.length} posts related to "${keyword}":`);
console.log(posts);
}
}
// Run the main function
main().catch(error => {
console.error("Error running the pipeline:", error);
});
Named Entity Extraction for the Posts
import { pipeline } from '@huggingface/transformers';
// Example of Reddit post data (this would be scraped using BrightData)
const redditPosts = [
"Tesla's stock price surged after the announcement of their new electric car model in Berlin.",
"Apple released new MacBook Pro models with improved performance and battery life."
];
// Initialize the NER pipeline
async function performNamedEntityRecognition(posts: string[]) {
try {
// Use Hugging Face's NER pipeline with a pre-trained model
const nlp = await pipeline('ner', 'dbmdz/bert-large-cased-finetuned-conll03-english');
// Loop through each Reddit post and extract named entities
const results = await Promise.all(
posts.map(async (post) => {
const entities = await nlp(post);
return { post, entities };
})
);
// Log the results
results.forEach((result) => {
console.log(`Post: ${result.post}`);
console.log("Entities:", result.entities);
console.log("-------------");
});
} catch (error) {
console.error("Error during NER:", error);
}
}
// Run NER on Reddit posts
performNamedEntityRecognition(redditPosts);
