Comparison
Both approaches are legitimate. They do not solve the same problem. This page helps you identify which one is yours.
An enterprise generative assistant (Microsoft 365 Copilot, Gemini for Workspace, ChatGPT Enterprise) goes live in days and needs no long training programme.
Broad coverage of personal production tasks: email, minutes, first-pass summaries, rewrites.
Per-seat billing, a short learning curve, experimentation without a cross-functional programme.
The assistant sits in Word, Outlook, Docs or Slack : where individual work already happens.
Each assertion in a deliverable is linked to its sources and carries a visible confidence score.
Draft, reviewed, approved: each stage records the identity of the person who signs.
An Audit Pack can be exported for a committee, a regulator or a statutory auditor.
The technical receipt of a run (versions, parameters, inputs) lets you replay the execution under the same conditions.
| Criterion | Generative assistant | NEXA |
|---|---|---|
| Primary purpose | Individual productivity | Binding collective decision |
| Source traceability | Varies by tool | Native, per assertion |
| Formal validation | Generally absent | Draft → Reviewed → Approved |
| Replay of a past execution | Not available | Available |
| Cost model | Per seat | Per execution |
| Time to deploy | Days | Weeks |
| Change management | Low | Structured around an existing process |

If your issue is speeding up individual production, a generative assistant is probably the right tool, and it will cost less. Deployment in days, immediate adoption, fit with suites already in place.
If your issue is defending a collective decision before a committee, a regulator or a statutory auditor, the question is no longer production speed but the solidity of the dossier: sources, signed validation, audit export, run replay.
No. Most of our clients keep their generative assistants for individual use. NEXA is used on processes where a decision binds the organisation.

A walkthrough on a process your teams already run. Then a framing session to size the first deployment.
