CADENCE keeps the story, channel drafts, approvals, artwork sizes and calendar for every release on your own computer. Drafts come from your own AI provider or a local model, and each approval is tied to the exact text. It never posts by itself: you finish each post, or send approved text to your own Buffer. No account, no telemetry. Windows and Apple Silicon Mac. Free trial on a sample release; $29 launch price until Nov 15, then $39, one-time.
