ChatGPT knows the internet. It doesn’t know your company.
ChatGPT can’t access your documents. AiSU connects to your cloud storage and returns cited answers from your own files.

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Where a vendor's support is limited or conditional we mark it partial rather than absent — tell us if anything here is out of date.
Why switch
What sets AiSU Strata apart
Grounded in your data
ChatGPT generates answers from its training data. AiSU retrieves answers from your actual documents — contracts, policies, reports, emails.
Budget reallocation
ChatGPT Pro costs €185/month for one user. AiSU costs €149/month for your entire micro organisation. Switch and save.
No hallucination risk
AiSU’s cited answers mean your team never acts on unverified information. Every claim links to the source.
