Studio activation workflows save outputs to generated assets for your brand. Campaign Builder lives at /halo-studio/campaign-builder; the Messaging matrix uses a run id you create in the browser.
Campaign Builder: /halo-studio/campaign-builder — brief → AI concept & headlines → edit → channel copy → review. Legacy /studio/campaigns/builder redirects here.
Messaging matrix: /studio/messaging/matrix — enter audience pain points and messaging pillars (pre-filled from Messaging Architecture session pillars, then published strategy fields, then research when available), then open Quick grid for pain-point × pillar cells (primary, alt, CTA, alignment score, Review badges) or Strategic system for a full Brand Intelligence brief with QA. Export CSV from Quick grid. Alignment failures show N/A on the score badge.
Credits and governance
Each step uses your plan credits. Matrix runs one generation per cell (with concurrency limits) plus alignment checks. Low scores surface in the UI; you can follow up in Brand governance like other tools.
Pre-fill pillars from your Messaging Architecture workflow session when present, then from published Messaging pillars strategy fields—both pages read them automatically for faster input.
