Comparison
RagNight vs Dust Which RAG infrastructure for your AI agents?
Dust and RagNight are both French tools for connecting AI to your company data. But they address different needs. Here is an honest comparison to help you choose.
The unified enterprise knowledge layer. Your teams — CS, HR, RevOps, Finance — connect ChatGPT, Claude or Dust to all their data in a few clicks, no developer needed.
The AI workspace. Ideal for creating and managing agents directly in Dust — complete UI, but limited to PDF/Word formats and native Dust connectors.

When to choose which?
Choose RagNight if…
- Your data isn't just in Notion or Drive — you have recorded meetings, emails, scanned files or Excel sheets to index.
- You want the whole company to query the same knowledge base, whether the assistant is ChatGPT, Claude or Dust.
- You want an automatic audit of the freshness and quality of your data (Knowledge Pulse).
- Your operational teams — CS, HR, RevOps — need an assistant that truly knows everything, not just what's in Notion.
- You already use Dust but want to give it access to data it can't read on its own.
- You're looking for a startup plan without a credit card, with a free trial.
Choose Dust if…
- You want an all-in-one workspace: Dust manages agents AND the interface, and your data is already in Notion/Drive/GitHub.
- You don't have data outside Dust's native connectors (no audio, no Outlook emails, no scanned files).
- Dust's product experience suits you as-is and you don't need to connect other AI tools.
