What Makes AI Text Sound Stiff
Language models default to a formal, precise register. They avoid contractions, favour multi-syllable verbs and produce sentences of uniform length. Three quick rewrites break the pattern:
- Contractions — "do not" → "don't", "it is" → "it's", "cannot" → "can't". Human writers contract by habit.
- Simpler vocabulary — "utilize" → "use", "commence" → "start", "facilitate" → "help", "implement" → "build".
- Sentence variety — pair a 4-word punch with a 30-word sprawl. AI flattens this rhythm.
What This Tool Does
It applies a curated replacement dictionary plus a conjunction-based sentence splitter. It is a fast first pass — you still need human editing to add specificity, opinion and voice. The tool does not invent facts, restructure arguments or paraphrase meaning.
Beyond Mechanical Rewrites
The real humanisation is editorial: add a concrete example, insert a contradictory opinion, cut a generic transition, replace a paragraph's "topic + 3 supports" structure with something less tidy. Use this tool for the mechanical 60% and do the editorial 40% yourself.
