Developer Tools & APIs
Developer Tools & APIs on AI Demos focuses on structured, agent-ready building blocks that turn messy inputs into usable data. Tools like Firecrawl for web scraping and data extraction, LlamaParse and Airparser for resume parsing and schema extraction, and AskYourDatabase for natural-language SQL queries show how teams can move from raw documents and web pages to clean outputs fast. If you’re shipping AI workflows, support bots, or data pipelines, this category helps you compare APIs by real behavior—not hype—so you can plug the right tool into production with confidence.

Best AI Tools to Scrape Web Pages Into Clean Markdown or Structured Data
We tested four AI web-scraping tools on three live targets—a cluttered recipe blog, a JS-heavy Nike product page, and a protected Glassdoor jobs page—to see which ones return usable Markdown or structured data with zero manual selectors.
Best AI Tools to Build a Website Chatbot From Your Knowledge Base
We tested six RAG chatbot tools on the same seven-document NovaTech knowledge base to see which ones could retrieve accurate answers, handle multi-document follow-ups, stay grounded under complex policy questions, respond responsibly to emotional edge cases, and deploy as embeddable website widgets.
Best AI APIs to Convert Complex PDFs to Clean Markdown
We tested hosted PDF-to-markdown APIs on the same three hard documents: a long hybrid annual report, a table-heavy financial report, and an image-only scanned research paper. The goal was usable markdown with OCR, tables, charts, and reading order preserved well enough for downstream RAG, search, and reuse.
Best AI Tools for Parsing Resumes via API (2026)
This ranking evaluates AI resume parsing APIs based on their ability to convert resume PDFs into structured, machine-readable data. Using the same three resume inputs across all tools—a clean single-column resume, a multi-column sidebar resume, and a messy real-world resume—we tested extraction accuracy, layout handling, JSON consistency, and automation readiness. The analysis highlights which APIs are best suited for ATS platforms, recruitment software, HR-tech products, and large-scale hiring workflows.
