Nuclia

Nuclia is a fully managed Agentic RAG platform — now sold as 'Progress Agentic RAG' after Progress Software acquired the Spanish startup — that turns any kind of file 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 EU-headquartered with European hosting options, making it a popular pick for European enterprises and public sector buyers who need GDPR-aligned managed RAG. Pricing starts with a 14-day free trial; the Starter plan is $700/month and caps you at 750MB per file (text only), 5GB indexed data, and 15k requests, with Growth and Enterprise tiers above for larger corpora, multimodal ingestion, on-prem deployment, SSO, and dedicated support. Best when you have heterogeneous content (audio, video, scanned PDFs) and don't want to build the ingestion pipeline yourself.
