Tutorials, comparisons, and deep-dives on RAG pipelines, LLM data pipelines, and web scraping for production AI systems.
Screenshot APIs and web scraping APIs both extract web content — but they're optimized for very different AI use cases. Here's a complete guide to choosing between them.
Learn how to extract structured JSON from visual web pages using screenshots and vision LLMs. Full Node.js and Python code, plus benchmarks across 3 page types.
Conversation history is just one type of agent memory. Semantic memory — structured knowledge about the world — is what lets agents reason about facts, not just recall chat logs.
Semantic scraping is the next evolution of web data extraction — extracting meaning, not just text. This guide explains what it means and how to implement it for AI applications.
SERP APIs return search result lists. Content scraping APIs return full page content. Learn when to use each and how to combine them for AI agent workflows.
A practical tutorial for extracting and crawling all URLs from a website's sitemap — with rate limiting, error handling, and clean markdown output for AI applications.
Add KnowledgeSDK to HuggingFace smolagents in under 20 lines. Custom @tool decorator, CodeAgent setup, and full content scraping vs DuckDuckGoSearchTool snippets.
Stagehand is a powerful open-source browser automation framework — but for AI agents that need web knowledge, there's often a simpler path. Here's when to use Stagehand and when to skip it.
Stateless agents forget everything. Stateful agents with web knowledge are unstoppable. Here's how to build agents that persist context AND stay current with the web.
Learn how to extract structured JSON data from any website using KnowledgeSDK. No CSS selectors, no broken scrapers — just a schema and an API call.
Looking for a Supermemory alternative? If your AI agents need to extract and search web content — not just store conversation history — KnowledgeSDK is the extraction-first approach.
Both are developer infrastructure for AI agents. One focuses on memory and session context. The other on extracting and searching web knowledge. Here's the real difference.
