02 · AI assistant

The AI assistant — from drafting a contract to spotting the risk

Nothing AI writes takes effect on its own. What it proposes is checked by the system against the schema rules, and only becomes a contract once you have reviewed and approved it.

AI proposes → the system validates → a human makes the final call.

Available now

Word/PDF → a structured contract

When a new official document arrives in the shared system it is pulled in and the right member of staff is notified.

Status stays in sync

Progress is synchronised with the shared system automatically, so the record is always current.

Organisations recognised

Organisations registered in Mongolia are matched and registered automatically from the shared directory.
