Voice-preserving humanization
Most humanizers flatten every draft into the same “native generic” paragraph. ChimpWrite does the opposite — it rewrites the statistical patterns detectors flag while preserving the rhythm of a second-language English writer. Your sentences still sound like you.
- Preserves L2-English cadence and phrasing
- Three levels: Light, Medium, Aggressive
- No over-rewriting that strips out personality
Free to start, stronger when you need it
Standard & premium engines
The free tier runs on our fast standard engine. Any credit pack — from $5, one-time, never expires — switches you to the premium engine, our most natural rewrite model, with higher word caps to match.
- Standard engine free: 1,500 words every month
- Premium engine with any pack — our most natural rewrites
- One-time credits, no subscription, never expire
No more “what strength do I pick?”
Document-type presets
Pick what you're writing and ChimpWrite tunes itself to the genre's conventions. Each preset already knows the tone, structure, and formality the document calls for.
- Personal Statement · Essay · Email
- Cover Letter · General
- Removes setup friction before you even start
A reading on every run
Instant authenticity estimate
Every humanization shows a before/after estimate of how human your text reads — 0 to 100, computed instantly. It's an honest directional signal, not a guarantee: detectors evolve, and we say so instead of promising magic.
- Before and after scores on every run
- Flags the patterns detectors look for
- Labeled an estimate — never a fake guarantee
Verify before you submit
Diff view — confirm your meaning survived
Every changed sentence is highlighted side by side so you can confirm your argument is intact before submitting. Nothing is altered behind your back — you see each edit and submit with confidence instead of fear.
- Changed sentences highlighted before/after
- Full history of every run on your account
- Removes the fear of an unreviewed submission
What's coming next
We'd rather show you a real roadmap than pretend everything already exists. These are in the works — clearly labeled until they ship.
Coming next
Independent detector verification
A paid add-on that checks your text against named third-party detectors — real independent verification instead of a humanizer grading its own homework. In the meantime we publish our editorial testing methodology openly.
- Named third-party detectors, real scores
- Independent proof, not self-marking
- Planned as a paid add-on

“Why this was flagged” explainer
When your input reads AI-written, ChimpWrite will name the patterns that triggered it — repetitive sentence length, low burstiness, predictable structure — instead of leaving you guessing.
- Names the exact patterns that flagged you
- Teaches what AI writing looks like
- Built on the same internal check as the estimate
Planned
Voice profile upload
Paste two or three of your own past essays and ChimpWrite will learn your voice, then match it on every future humanize — so the output sounds consistently like you across documents.
- Upload 2–3 authentic past essays
- Builds a reusable profile of your style
- Consistent voice across every document
Planned
Citation & reference preservation
An academic mode that never touches citations, quotes, or reference lists. For thesis and essay writers, a humanizer that mangles a reference is worse than useless.
- Citations, quotes, and references locked
- Critical for theses and graded essays
- Humanize the prose, not the scholarship
Planned
Browser extension
The SOP and email workflow lives in Google Docs, not on our site. A ChimpWrite extension will let you humanize in place — inside Google Docs, Gmail, and Word Online — without breaking your flow.
- Docs · Gmail · Word Online
- Humanize without leaving your document
- Meets the workflow where it happens
Features FAQ
Two things. First, voice preservation: most AI humanizers rewrite your text into a flat “native generic” style, while ChimpWrite preserves a second-language English writer's natural cadence and phrasing. Second, honesty: every run shows a before/after authenticity estimate that is clearly labeled an estimate — not a fake “100% undetectable” badge — plus a diff view so you can confirm your meaning survived.
No honest tool can guarantee that — detectors evolve constantly, and we say so plainly. What ChimpWrite gives you is an instant authenticity estimate on every run showing how human your text reads before and after, based on the same statistical patterns (uniform sentence length, low burstiness, predictable phrasing) detectors score. Independent third-party detector verification is planned as a paid add-on.
