Trace, govern and optimize your shared Power BI semantic models across the Service.
Same online connection, broader scope. Scan your whole tenant and answer the questions IT, security and finance keep asking — who owns what, who has access to what, what's actually being used. Tenant analysis docs →
Trace a single column from a source table through every dataflow, semantic model and report — all the way to the individual visual that renders it. End-to-end. No gaps. Nobody else does this.
Copilot in Power BI, Microsoft Fabric Data Agent and every BI Q&A tool are only as good as the model behind them. Three high-leverage cleanups before you turn AI loose on your tenant.
Unused columns inflate the model the AI has to index. Unused measures get suggested as answers nobody intended. Unused tables muddy the lineage the AI is supposed to follow. Measure Killer finds and removes them — at tenant scale, with impact analysis so nothing breaks.
Decommissioned reports and stale pages get suggested by Copilot alongside the ones your team actually uses. Measure Killer surfaces views per report and per page so you can archive the dead weight — Copilot only sees what's alive and worth your team's attention.
Cryptic field names, undocumented measures, missing descriptions and anti-patterns all degrade AI suggestions. The best-practice analysis runs across every model and report in your tenant — fix the worst violations once and every AI tool gets better overnight.
Measure Killer's tenant exports are the richest Power BI metadata you can get anywhere — every DAX expression, every M query, full report lineage, refresh events, best-practice violations, used vs. unused columns and measures, page-level consumption with average load times, and now capacity cost. Feed that to a frontier AI model and you get prioritized optimization suggestions ranked by real financial and performance impact — not generic best-practice noise.
Lineage is only trustworthy if every reference is found. Measure Killer traces each one — down to a tooltip, a conditional-formatting rule, or a measure nested inside another measure — so you see the full downstream impact before you rename, move or remove anything. At 99.99% reference-detection accuracy (the best in the industry), that's the difference between a confident change and a quiet outage. The handful of edge cases that can still slip through are listed transparently.
