Merlin is a single AI sidebar tied to one model. CouncilMind is a multi-model council that queries GPT-5, Claude Opus 4.6, Gemini 2.5 Pro, and DeepSeek V4 in parallel, then returns a consensus you can act on.
The right metric for retention is cohort-based, not aggregate—Merlin would have given you the aggregate.
Cohort retention is right, but daily granularity is overkill—weekly cohorts surface the signal faster.
Combining: weekly cohorts plus a 30-day rolling window for the dashboard.
One model, one bias. A council, four perspectives, one consensus.
Every query goes to every available model at once. No model-switching menu.
When models disagree, you see exactly where. That's where the real insight lives.
Run the same query as a skeptic, an optimist, a domain expert, or a devil's advocate.
Same fast workflow, four times the perspective
Anything from a quick fact-check to a strategic decision.
Four models respond in parallel, you see each stream live.
One synthesized answer with disagreement clearly marked.
