Guru requires you to build a knowledge base. AiSU searches the one you already have.
Guru is a knowledge management platform you have to maintain. AiSU retrieves from the systems where your knowledge already lives.

Where they actually differ.
Compiled from each vendor's published documentation and pricing, July 2026. AiSU Strata prices are flat-rate per organisation in EUR, excluding VAT. Where a vendor's support is limited or conditional we mark it partial rather than absent — tell us if anything here is out of date.
The hidden cost
The licence is the cheap part. The upkeep is not.
Why switch
What sets AiSU Strata apart
No migration, no curation
AiSU connects to your existing cloud storage. No one has to create or maintain a separate knowledge base. If a policy changes, the cited answer reflects the updated document immediately.
Cross-platform retrieval
Guru searches Guru. AiSU searches your Google Drive, OneDrive, and SharePoint simultaneously — including all the knowledge that was never migrated to any knowledge base.
Lower cost at scale
Guru at €25/seat for 50 users costs €1,250/month. AiSU costs €699/month for the same team — and searches your existing systems instead of a separate repository.
