Our verdict

ChatGPT is an excellent general tool that can occasionally help on a proposal (rewording, plan inspiration). But it is NOT a public procurement tool: no BOAMP watch, no factual Go/No-Go, no automatic DC1/DC2/DUME, risk of hallucinating French legal articles, and US hosting non-compliant with some public entities' GDPR requirements. Optimal combination: Maître AO for the main workflow (analysis, proposal, admin), ChatGPT as a complement for general tasks.
