You already have Copilot. Here's what it can't do.
Microsoft 365 Copilot searches Microsoft only. AiSU searches across all your platforms — with cited answers.

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Where a vendor's support is limited or conditional we mark it partial rather than absent — tell us if anything here is out of date.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 per-seat problem
Per seat, the answer costs more the more people need it.
Why switch
What sets AiSU Strata apart
Cross-platform search
Copilot can’t search Google Drive. If your organisation uses multiple platforms, you’re searching blind on everything outside M365.
73% cost savings at 50 users
AiSU costs €699/month for a 50-person org. Copilot costs €1,050-1,500/month for the same team. And with AiSU, everyone gets access.
Verifiable answers
AiSU cites the source document for every claim. Your team can verify any answer in seconds.
