The platform is used by about 1,050 municipalities and 550,000 public employees for tasks like assembly response drafting, welfare administration, and legal search. Polimill adopted Codex across its engineering workflow, from requirements to testing, citing a 3-5x increase in development speed. Less-experienced staff using AI and accumulated administrative data produced policy proposals approaching veteran-quality output, though top marks still went to experienced officials due to tacit knowledge. Polimill plans a fall 2026 rollout of Qommons ONE, an app marketplace with a super-agent orchestrating multiple AI systems and third-party apps for municipalities. ## Full article daily.dev links to this article rather than hosting it.
