Key features	Synthesizes knowledge from PDFs, Excel, CAD, databases, tickets and wikis Cited, source-traceable answers Specialized agents: sales engineering, diligence, legal, patent prosecution Human review queue before information enters the knowledge base Cloud, on-premises or air-gapped deployment	Unified control layer for building, governing and scaling enterprise agents Deployment across cloud, on-premise and fully air-gapped environments Security and governance controls built into the platform rather than added later Monitoring and observability across agents in production Extensible ecosystem for connecting enterprise systems and data
Pros	Explicitly refuses to guess when evidence is insufficient, rather than always answering Cited, source-traceable answers support real accountability Air-gapped deployment option for genuinely restricted data environments	Air-gapped support opens use cases most agent platforms cannot serve Governance built in rather than bolted on after a pilot Single control layer avoids ungoverned departmental sprawl
Cons	Review-queue safeguard depends on the review actually being performed rigorously No self-serve pricing - requires booking a working session Specialized agents (legal, patent) still need domain-expert oversight, not blind trust	Enterprise implementation effort, not a self-serve signup Pricing is not published, requiring a sales process
