The pipeline
Multiple readers, one structured output
When you submit your work, Marnie doesn't run a single pass. It sends your document to multiple readers simultaneously — each looking at the same text from a different critical angle. These reads happen independently, so there's no anchoring effect where one opinion shapes the others.
After the first pass, an auditor reviews what each reader found. It checks for overlap, contradiction, and weak reasoning. Issues that don't hold up under that review are filtered out. What remains goes into the next pass, and the process repeats until no new issues are being found.
The final output is a consolidated findings report — ranked by severity, with notes on what the issue is and why it matters.
Why multiple passes
A single read of a document — even a careful one — will miss things. Some issues only become visible when you've already worked through the surrounding context. Others are easy to overlook when you're reading in sequence, but stand out when you come back with fresh attention.
Multiple independent passes with an auditor layer means that issues which show up consistently are surfaced, while noise — things that looked like a problem on first read but didn't hold up — gets filtered before it reaches you.
The auditor
After each set of reads, a separate process reviews the findings before they move forward. It checks whether each issue is specific enough to act on, whether it duplicates something already captured, and whether the reasoning behind it is sound. Issues that fail that check are dropped.
This is what separates Marnie from tools that generate feedback in a single pass. Everything that reaches you has been reviewed at least twice — once when it was identified, and once when it was checked.
Scope options
Full Manuscript runs the complete pipeline on your entire document. All eight section modes run a focused version of the pipeline on a specific part — Abstract, Introduction, Literature Review, Methods, Results, Discussion, or Conclusion. Section mode uses fewer passes and is faster; it's useful when you know exactly what you want reviewed.
