Humanise AI text. Canadian spelling included.
Colour, favour, behaviour and centre survive the rewrite. A humaniser that respects how Canadians actually spell.
Humanise versus humanize, settled in one paragraph
Both spellings are correct. Humanize is standard in the United States and common in Canada; humanise follows British convention and remains the natural choice for many Canadians, particularly anyone educated on Commonwealth English. Canadian usage happily mixes the two systems, organize but colour, realize but centre. Thousands of Canadians search for an AI humaniser every month, and most tools, built for the American market, neither use the spelling nor respect it in your text. This page is for you, and so is the tool above.
Why spelling preservation actually matters
Here is the failure mode nobody warns you about. You paste a carefully written Canadian English draft into an American humanizer. The output reads smoother, but colour has become color, behaviour has become behavior, and the cheque your client owes you is now a check. Submit that to a Canadian employer, a government posting or a university with style requirements, and the Americanisms read as carelessness, the exact opposite of what you wanted from polishing the text.
This humaniser preserves the spelling conventions of your input. Canadian and British spellings pass through the rewrite untouched, because the engine treats them as your voice, not as errors to correct. The same respect extends to vocabulary: a draft that says hydro bill or toque does not come back saying electricity bill and beanie. Your text stays Canadian while losing the machine cadence.
Same engine, full strength
To be clear about what this page is: the same humanizer that lives on the homepage, at full capability. Up to 6,000 characters per run, three tones, French support, processed in memory and never stored, complete results with no account. We built a page for the humanise spelling because meeting people at their own spelling beats pretending only one variant exists. The engine underneath plays no favourites, and yes, favourites keeps its u.
A note for editors and teams
If you edit other people's writing, the spelling preservation matters twice over. You can run a colleague's AI assisted draft through the humaniser without introducing a spelling system your style guide forbids, and without the silent vocabulary swaps that force a second proofread. The output respects the conventions of the input, which means your red pen stays focused on substance, where it belongs.
