With Codex, finance teams can just build things. Start with the close workbooks, revenue and expense dashboards, forecast updates, prior MBRs, and owner notes you already use. Codex can help turn that context into tangible assets your team can review, refine, and share, no coding required. Use it to spend less time assembling the first pass and more time shaping the story, checking the numbers, and preparing for the decisions ahead.
