What is DataFuel?
DataFuel is a web scraping API that converts websites into LLM-ready data (markdown, JSON, plain text, or HTML) for RAG systems and model training or fine-tuning. It has GPT-4-powered extraction into custom JSON schemas, authenticated and gated-content scraping with credential encryption, and automated login and retries. Usage is credit-based: one credit per URL scrape, and 15 credits per URL for AI-schema extraction.
Our verdict
DataFuel is a solo-founder product built to solve the founder's own scraping problem for his other product, ChatNode. It has no disclosed funding round, which sets it apart from the category's more established players. It fits teams that want ready-made LLM-formatted output with schema-based extraction, though buyers who need enterprise-scale support should weigh that small-team footprint.
Categories:
AI extraction tools sit between a raw page and your database: you describe the fields you want, and a model returns structured JSON or LLM-ready markdown without hand-written selectors. They hold up well when page layouts change often, at the cost of per-request model spend and the occasional wrong field.
