Rosey Version: v0.3.2
Released April 16, 2026
Rosey for Microsoft Word is now available in limited access beta. This is the first public release of Rosey — an independent quality layer for documents touched by AI.
What Rosey does
Rosey works inside Microsoft Word to find and fix errors, omissions, and weaknesses in high-stakes business documents — investment memos, client deliverables, board reports, and similar deliverables where document quality has real consequences.
It does this in two ways:
Claim verification. Rosey checks the factual and quantitative claims in your document against the supporting material you provide. Contradicted, unsupported, and weakly-supported claims are surfaced for your review.
Expert reviewer simulation. Rosey simulates expert reviewers — a CFO, IC Chair, Industry Analyst, Operating Partner, Adversary, Audience CEO, and others — to surface weaknesses from each perspective before a real high-stakes reader does.
Rosey fixes what it can as tracked changes and flags what it can’t, with citations and rationale, all inside the Word workflow you already use.
Available in this release
Microsoft Word add-in. Install from the Microsoft AppSource marketplace; works in Word for Windows, Mac, and the web. See: Installing the Rosey add-in.
Project workspaces. Group a document with its supporting material and reviewer configuration. Create projects right from inside Word.
Supporting material upload. Provide source documents — financials, transcripts, reference PDFs — that Rosey treats as authoritative when verifying claims. Supports PDF, DOCX, XLSX, CSV, TXT, and Markdown.
Built-in reviewer library. 9 reviewers ship with Rosey: Accuracy, Adversary, Audience CEO, CFO, IC Chair, Industry Analyst, Operating Partner, Operations, and Readability.
Findings panel with three tabs. To Do (issues to act on), Review (suggested edits awaiting your decision), and FYI (minor changes and observations that don’t require action).
Tracked-change integration. Suggested edits are applied as Word tracked changes; accept or reject them from the Rosey side panel.
Source traceability. Every supported claim is one click from its source. Contradicted claims open the supporting material at the exact line where the contradiction occurs.
Benchmark
We ran a formal benchmarking study to test how well AI catches errors in AI-generated work. We had a leading model produce an earnings summary from real source documents, hand-verified the output to identify the errors it contained, and then tested whether leading AI models could catch those same errors.
The best model found fewer than half. Rosey caught 4x more errors and had a 4.1x lower false-positive rate than the average LLM configuration.
Full study materials, including the test corpus, will be published soon so you can run the benchmark yourself.
Getting access
Rosey is available to a limited group of beta users during this release. To request access, visit insummary.com/request-access. New beta users are onboarded on a rolling basis.
What’s next
Future releases will expand Rosey beyond Word into additional integrations, deepen reviewer customization (including user-created reviewers based on real individuals), and broaden the data source footprint with knowledge sources teams already maintain.
