An honest, side-by-side comparison of two AI writing tools — what each does best, and which one fits your goal.

## How it works

1. **Paste your text** — Drop in AI output to test Humanit yourself.
2. **Pick a tone** — Choose from 10 modes — Casual to Ultra.
3. **Humanize** — See the rewrite in seconds.
4. **Verify** — Check it with the built-in AI detector.

## Quick verdict

Pick QuillBot if your main job is rewording and paraphrasing text; pick Grammarly if you mostly need grammar, spelling, and style fixes as you type across every app. They overlap in the middle (both check grammar, both paraphrase a little), but each is clearly built around one of those two jobs.

## What QuillBot does best

QuillBot is a polished paraphraser with multiple rewrite modes, a summarizer, a citation generator, and browser extensions. It is the better pick when you want to restate sentences in different words while keeping the meaning, and it bundles lightweight grammar and plagiarism checks on paid tiers.

## What Grammarly does best

Grammarly is a mature, real-time grammar and style assistant that works almost everywhere you type, with clear explanations for each suggestion and tone feedback. On premium it adds a plagiarism checker and an AI detector. It is the better pick for polishing writing you have already drafted.

## Where Humanit fits

Humanit is a free all-in-one writing kit: grammar checking with a reason for every fix, a paraphraser, a summarizer, an AI humanizer with 10 tone modes, and a built-in AI detector to verify your text.
