Grubby AI is a powerful tool that can humanize AI text and bypass AI detectors.

In other words, it rewrites robotic content and transforms it into natural-sounding writing. This process helps users pass AI detection tools while improving readability.

Writers often use AI to speed up content creation. But raw AI text can sound flat, repetitive, and inauthentic. That's where Grubby AI steps in.

According to thisGrubby AI review, the tool is designed for simplicity. It supports content writers, students, marketers, and social media managers.

Grubby's humanization technology modifies sentence structure, vocabulary, tone, and rhythm. The result? Text that reads like it came from a human, not a machine.

Some call it part of the "human loop," where AI generates content, and tools like Grubby refine it for real-world use.

Grubby AI does a decent job. But it has limits, especially in its free version.

This is where the Humanize AI of Toolsmart offers a significant upgrade.

Humanize AI of Toolsmart offers a free and effective alternative to Grubby AI to humanize the text.

Here's why I recommend it.

1. Free and Easy Access

Toolsmart's humanizer doesn't hide behind paywalls or word limits.

You don't need to download any software or create an account to use it. Go to theToolsmart Humanize AI page and start humanizing your content immediately.

In contrast, Grubby's free tier only lets you process three short texts per month.

Toolsmart has no such restriction.

2. Eight Humanized Modes for Every Writing Style

Toolsmart gives you more than just a one-click option.

You can choose from eight unique humanization modes, each crafted for different goals. These include:

  • Creative – Adds personality and storytelling tone

  • Formal – Suited for business, academic writing

  • Casual – Light, relaxed tone

  • Marketing – Optimized for conversion and engagement

  • And more...

Whether you need content for blogs, essays, sales copy, or personal messages, there's a mode to match your voice.

From my experience, the Marketing mode has helped sharpen product descriptions and make CTAs feel natural, not robotic.

3. Customize the Level of Humanization

Here's what makes Toolsmart truly stand out:

You can adjust the level of human-like sound in the output.

There is a slider to adjust the intensity of human tone. You can go from light edits (just smoothing sentences) to complete rewrites that add flow, nuance, and emotional tone.

This is ideal when you need precise control over your final content. Grubby doesn't offer this level of customization.
