Agentic RAG-as-a-service from Progress: auto-indexes any file or document and powers LLM use cases with one API — EU-friendly, multilingual, multimodal.
Nuclia is a fully managed Agentic RAG platform (now part of Progress Software) that turns any kind of file — PDFs, audio, video, images, web pages, transactional database rows — into structured, retrievable knowledge ready for LLMs and agents. You upload or stream content to a 'Knowledge Box' and Nuclia handles OCR, transcription, translation, semantic chunking, embedding, and indexing automatically; queries return answers with citations, supporting passages, and source files. The differentiators are multimodality (it ingests audio and video natively, not just text), multilinguality (50+ languages with cross-lingual retrieval), and the agentic posture: Nuclia exposes search, ask, and remix endpoints plus an MCP server so agents can plug it in as a tool. It is a Spanish/EU-headquartered company with hosting in Europe, making it a popular pick for European enterprises and public sector buyers who need GDPR-aligned managed RAG. Pricing starts with a free developer tier and scales to per-Knowledge-Box subscriptions plus usage on processing and queries; enterprise plans add SSO, on-prem deployment, and dedicated support. Best when you have heterogeneous content (audio, video, scanned PDFs) and don't want to build the ingestion pipeline yourself.
