Every number in the report has to still be that number afterwards
What makes a research report valuable is its data and its conclusions. HumanPen rebuilds only the narrative sentences - figures, units, percentages, exhibit numbering, and the wording of your findings stay exactly as written.

Reports fail when a rewriter helpfully edits the data
General-purpose rewriters fail on reports in a particularly dangerous way: they turn "grew 23.4%" into "grew by almost a quarter", "n=412" into "just over four hundred samples", and "statistically significant (p < 0.05)" into "a clear difference".
Each of those reads more naturally, and each one damages the report - a precise figure replaced by a vague one, a statistical criterion erased, the strength of a finding quietly altered. These errors are also nearly impossible to catch: across forty pages, nobody re-verifies every number.
HumanPen treats numeric values, units, percentages, statistical notation, and exhibit numbering and captions as protected content that never enters the rewrite. What gets rebuilt is the prose carrying them - the over-tidy transitions like "This section will analyse the factors influencing..." that are exactly where AI phrasing concentrates.
Reports have one more structural trait: they are chart-heavy. Charts and tables are independent objects in Word, so their positions, numbering, and captions never enter the text rewrite. After processing, every exhibit is still in place with the same number, and an in-text "as shown in Figure 3" still points where it should.
Frequently asked questions
Are numbers and percentages really left alone?
Numeric values, units, percentages, and statistical notation are treated as protected content and never rewritten. We still recommend spot-checking your key figures before submitting - that is simply responsible practice, and no tool can take responsibility for your report’s accuracy.
Will charts or tables shift?
No. Charts and tables are independent structural objects; positions, numbering, and captions stay as they were, and in-text cross-references to them stay correct.
Will my conclusions be reworded?
The sentences are rebuilt, but the content and strength of a finding are preserved - "a significant correlation" does not become "seems related". If you want the conclusions section untouched entirely, use "specify content" to exclude it.
The report is dozens of pages. Can it handle that?
Yes. No page limit; slices process in parallel, and a report of several tens of thousands of words typically finishes in tens of minutes.
Can I rewrite only the literature section and leave the analysis chapters?
Yes. Scope it with "specify content" - everything else is frozen and not billed.
Can it handle a Chinese-language report?
Not yet - the engine is currently tuned for English.
