Stop wasting money on stale data.

Keep your RAG system fresh—automatically.

AI generates extraction strategies in seconds—no coding required. Uses an LLM once, then switches to fast raw scraping for speed, consistency, and price. Monitor any website, detect real changes, and sync only what matters. Cut embedding costs by up to 95%.

Smart Routing

Uses an LLM once to generate strategies, then switches to raw scraping (CSS selectors, DOM parsing) for speed, consistency, and cost-efficiency. Auto-detects APIs for speed, falls back to selectors for reliability.

Semantic Diffing

Ignores ads, timestamps, and layout noise. Only alerts on meaningful content changes that matter to your RAG.

Push or Pull

Webhooks push changes to you instantly. Or poll our API on your schedule. Fits any architecture.

Stop wasting time on custom scrapers

Why spend weeks writing and maintaining selectors? Our AI does it in seconds, then monitors changes automatically.

The Old Way

// Write custom scraper with tons of selectors

const cheerio = require('cheerio');

const axios = require('axios');

async function scrapeProducts() => {

const html = await axios.get('https://shop.com');

const $ = cheerio.load(html.data);

const products = [];

$('.product-item').each((i, el) => {

const name = $(el).find('.product-title h2').text().trim();

const price = $(el).find('.price .amount').text();

const image = $(el).find('img.product-img').attr('src');

const desc = $(el).find('.description p').text();

const rating = $(el).find('.stars .rating-value').text();

const stock = $(el).find('.inventory .stock-count').text();

const sku = $(el).find('[data-sku]').attr('data-sku');

const category = $(el).closest('.category-section').find('.cat-name').text();

const brand = $(el).find('.brand-logo').attr('alt');

const reviews = $(el).find('.review-count').text();

const discount = $(el).find('.badge.sale').text();

const tags = $(el).find('.tags .tag').map((i, t) => $(t).text()).get();

const variants = $(el).find('.variants .variant-option').map((i, v) => {

size: $(v).find('.size-label').text(),

color: $(v).find('.color-swatch').attr('data-color'),

price: $(v).find('.variant-price').text()

}).get();

products.push({ name, price, image, desc, rating, stock, sku, category, brand, reviews, discount, tags, variants });

});

// Now handle pagination, rate limiting, error handling...

return products;

}

Expensive embeddings • Wasted compute • Slow updates

With meter

// Setup once - AI generates strategy

const strategy = await meter.generateStrategy({

url: 'https://example.com',

description: 'Extract products'

});

// Webhook only fires on real changes

meter.onChange((changes) => {

await pinecone.upsert(changes);

});

Cut embedding costs • Real-time updates • Zero waste

Why teams choose meter

Stop serving stale data. Start saving money. Keep your RAG system accurate—automatically.

Never serve stale data

Automatic change detection ensures your vector database stays current. No more outdated search results or hallucinations from stale data.

Save up to 95% on embedding costs

Only re-embed what actually changed. Skip ads, timestamps, and layout updates. Teams report saving thousands per month.

Set it and forget it

Configure once, monitor forever. Automatic scheduling handles everything. Get webhooks when content changes, silence when it doesn’t.

Works with your stack

RESTful API integrates with any backend. Webhooks for real-time updates, or poll our API. Works with Pinecone, Weaviate, Qdrant, and more.

Frequently asked questions

How does AI strategy generation work?

Simply provide a URL and describe what you want to extract. Our AI analyzes the page structure, identifies the best extraction method, and generates a strategy. You can refine it with feedback if needed—all without re-scraping the page.

How do you detect changes?

We use a combination of content hashing, structural signatures, and semantic similarity. This means we ignore ads, timestamps, and layout changes—only alerting you when the actual content you care about has changed.

What happens after the AI generates a strategy?

Once the strategy is created, meter switches to raw scraping (CSS selectors and DOM parsing) for all future scrapes—no LLM costs. You only pay for the initial generation. This gives you the speed, consistency, and cost-efficiency of traditional scraping with the intelligence of AI-powered setup. Scrapes run fast and efficiently using the saved strategy, saving you money on every run.

How do webhooks work?

When we detect meaningful content changes, we POST the updated data to your webhook URL. You can then update your vector database with only the changed content. If nothing meaningful changed, you won’t get a webhook—saving you processing time and costs.

What sites can you scrape?

We handle JavaScript-heavy sites, dynamic content, paginated data, and more. Our system automatically chooses the best extraction method—whether that’s API calls or CSS selectors.

How does pricing work?

Free during beta—no credit card required. Future pricing will be based on the number of sites monitored, not per-scrape. No hidden fees, no per-request charges. Flat monthly pricing that scales with you.
