# 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.

## Rankings

- [Best AI Tools for Memory for AI Agents](https://aidemos.com/best/ai-agent-memory-tools) — We tested five memory tools with the same multi-session prompts to see which ones can remember user style, client history, project direction, and delete/forget requests without leaking stale context.
- [Best AI Tools to Scrape Web Pages Into Clean Markdown or Structured Data](https://aidemos.com/best/ai-web-scraping-tools) — 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](https://aidemos.com/best/knowledge-base-chatbot-builders) — 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](https://aidemos.com/best/pdf-to-markdown-apis) — 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)](https://aidemos.com/best/resume-parsing-api) — 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.

## Use Cases

- [Query Live Databases Using Plain English with AI](https://aidemos.com/use-cases/query-live-databases) — This use case shows how business users can query a live database using plain English instead of writing SQL. We tested five AI database tools on the same ecommerce database and found AskYourDatabase to be the best practical workflow because it showed generated SQL, returned readable business answers, handled follow-ups well, and surfaced operational risks like pending-but-paid orders. The page also covers real outputs, limitations, and when users should still review the SQL before acting on results.

## Tools

- [Cognee](https://aidemos.com/tools/cognee) — Inspectable graph-backed memory for AI agents, with strong provenance tracing but cautious update/delete behavior.
- [Supermemory](https://aidemos.com/tools/supermemory) — Hosted agent memory with strong capture and scoping, but mixed retrieval and weak forget behavior.
- [Hindsight](https://aidemos.com/tools/hindsight) — Selective, inspectable memory for real agent workflows, with strong retrieval and scope control.
- [Mem0](https://aidemos.com/tools/mem0) — Mem0 remembers useful agent context across sessions and makes retrieved memory visible, but stale context can linger after updates or forget requests.
- [Zep](https://aidemos.com/tools/zep) — Developer-first memory for AI agents that captures workflow context well, but still needs stronger stale-memory and forget control.
- [Airparser](https://aidemos.com/tools/airparser) — Structured resume parsing across clean, multi-column, and messy PDFs, with fast JSON output and a few field-quality caveats.
- [Skyvern](https://aidemos.com/tools/skyvern) — Visually navigates messy and JS-heavy pages to extract clean structured outputs, but it runs slower than text-first scrapers.
- [Firecrawl](https://aidemos.com/tools/firecrawl) — Reliable on JavaScript-heavy and bot-protected pages, but its markdown output usually needs a cleanup step.
- [Jina AI Reader](https://aidemos.com/tools/jina-ai-reader) — Turns public URLs into LLM-ready text, with the strongest tested results on static pages and weaker results on JS-heavy or protected sites.
- [Spider](https://aidemos.com/tools/spider) — Fast static-page scraping, but weak cleanup and poor reliability on dynamic or protected sites.
- [Upstage AI](https://aidemos.com/tools/upstage-ai) — Solid on native financial tables, but unreliable for multi-column and scanned-document structure in markdown conversion.
- [Nutrient.io](https://aidemos.com/tools/nutrient-io) — A developer-first PDF-to-markdown API that handles straightforward OCR and hierarchy well, but loses fidelity on complex tables, charts, and handwritten visual content.
- [Landing AI](https://aidemos.com/tools/landing-ai) — A capable PDF-to-markdown API for complex financial and scanned PDFs, with strong table and chart extraction but inconsistent heading semantics.
- [Mistral AI](https://aidemos.com/tools/mistral-ai) — A strong hosted PDF-to-markdown API for mixed and scanned documents, with solid OCR, table recovery, and asset export but uneven structural fidelity.
