A lab report should not be made to sound more natural - it is supposed to read that way
Lab reports follow disciplinary conventions: passive voice, fixed sections, measurements precise to the unit. General rewriters, chasing natural-sounding prose, tend to strip exactly those. HumanPen rewrites within the academic register and leaves the conventions alone.

AI phrasing and disciplinary convention look similar - they are not the same thing
Lab reports read somewhat mechanically by design - that is the convention, not a flaw. The methods section uses passive voice ("The solution was heated to 80°C") to keep focus on the procedure rather than the person performing it, and the fixed introduction / methods / results / discussion structure exists so others can reproduce the work.
The problem is that general rewriters treat these as things to fix. "The solution was heated to 80°C" becomes "We heated the solution up to around 80 degrees" - voice changed, precision lost, and the conventional third person swapped for first. AI phrasing may well be reduced; so is compliance with the format you were asked to write in.
The actual AI signal sits elsewhere: the discussion section’s tidy, evenly unfolding argumentation in every paragraph, and introductions that lay out background without a single judgement of your own. Those are the parts worth rebuilding.
HumanPen rewrites within the academic register: passive voice and third person are preserved, section structure is preserved, measurements and units keep their exact form, and what gets rebuilt is the over-templated argumentation in the discussion and introduction.
Frequently asked questions
Will passive voice in the methods section be switched to active?
No. The rewrite stays within the academic register; passive constructions and third-person phrasing in methods are preserved rather than casualized.
Will measurements, units, or error margins change?
No. Numeric values, units, and statistical notation are treated as protected content. Spot-checking key data before submission is still recommended.
What about chemical formulas, equations, and sub/superscripts?
Unaffected. Equations and specialized typesetting are structural objects and never enter the text rewrite.
Lab reports are short - is it worth processing one?
Billing is on words actually rewritten, so a 1,500-word report is about 150 credits (roughly $1.50). If several are due the same week, upload them separately - up to three jobs run at once. Note the 10-credit minimum per job.
Can I rewrite only the discussion?
Yes, and we recommend it. Discussion and introduction are where AI phrasing concentrates; methods and results are supposed to read conventionally. Scope it with "specify content" - the rest is neither processed nor billed.
Can it handle a Chinese-language lab report?
Not yet - the engine is currently tuned for English.
