Humanize AI

Make ChatGPT outputs sound human via Smart Mode

Add HUMANIZE (or HUMANIZE THIS TEXT) in AI Configuration. MultipleChat's AI Collaboration runs a second pass that performs a meaning-safe ChatGPT paraphrase, varies cadence, and scrubs AI clichés—so your copy reads natural. If you're searching how to make ChatGPT outputs sound human or want to reduce patterns that trigger detectors (avoid ChatGPT detection), this is the switch.

  • One-word setup: HUMANIZE
  • Human cadence: short + long sentence mix
  • Cliché scrub: no "in conclusion", "moreover"

Note: Detectors vary. We focus on authentic, human-sounding writing.

Before → After

Before

"In today's digital landscape, artificial intelligence technologies are revolutionizing business operations across multiple sectors. Organizations are increasingly adopting AI-driven solutions to optimize workflows, enhance decision-making processes, and improve overall operational efficiency."

After (HUMANIZE)

Artificial intelligence has become a critical general-purpose technology reshaping organizational processes across sectors. Firms increasingly deploy AI-enabled systems to streamline workflows, support evidence-informed decision making, and improve operational efficiency at scale.
