Grammarly vs ChatGPT vs Levee: the definitive comparison for serious writers
Let's be direct.
Grammarly is a spellchecker with aspirations. ChatGPT is a generalist that happens to write. Levee is built for writers who care about voice and control.
They're not the same thing. They don't solve the same problem. And if you're a serious writer, you need to know which one to use—and when.
What each tool actually does
Grammarly checks your grammar. That's its core function. It catches typos, suggests better word choices, and flags passive voice. It's useful. It's not transformative.
ChatGPT generates text. Give it a prompt, it produces a draft. It's impressive. It's also generic. The output sounds like the statistical average of the internet.
Levee helps you write. It doesn't generate full drafts. It extracts your style from a sample, then suggests words and sentences as you pause. You write. It assists. You stay in control.
The feature comparison
Let's look at what actually matters for writers.
Voice preservation
Grammarly doesn't care about your voice. It cares about grammar rules. ChatGPT has no concept of your voice. It generates prose that's technically correct and completely generic.
Levee extracts your voice from a sample. Every suggestion passes through that filter. The output sounds like you. Not a robot. Not a committee of interns. You.
Control over the output
Grammarly offers suggestions. You accept or reject them. ChatGPT spits out a full draft. You spend hours rewriting it.
Levee offers ghost-text suggestions as you pause. Hit Tab to accept. Keep typing to ignore. Word by word. Sentence by sentence. You're in control.
Context and research
Grammarly has none. ChatGPT has what you put in the prompt. Levee has context references and fact lookup. Feed it URLs, articles, or notes. It writes with that context in mind. Highlight a paragraph and it finds relevant facts. No more switching to a browser.
Model flexibility
Grammarly uses its own model. ChatGPT uses one model. Levee lets you pick. DeepSeek for fast autocompletes. Mistral for EU privacy. Claude for polished prose. Switch per document.
Pricing
Grammarly Premium is $12/month. ChatGPT Plus is $20/month. Levee Starter is $10/month with rollover credits. Pro is $20/month for heavy users. Free plan with 50 credits. No card required.
The workflow difference
Here's how each tool fits into your workflow.
With Grammarly
You write. Grammarly underlines things in red and green. You fix them. You're done.
With ChatGPT
You write a prompt. ChatGPT generates a draft. You read it. You rewrite it. You edit it. You fact-check it. You do the hard part after the AI did the easy part.
With Levee
You start writing. Levee suggests the next word, sentence, or paragraph in gray. You accept or ignore. You pause, the suggestion appears. You never break flow. You never leave writer mode. You're the author.
The use case matrix

The bottom line
These tools serve different purposes.
Grammarly is a specialized tool. It fixes your grammar. It doesn't help you write better.
ChatGPT is a generalist. It generates text. It doesn't preserve your voice.
Levee is an assistant. It helps you write better, faster, and in your own voice.
If you just need a spellchecker, use Grammarly. If you want to generate drafts, use ChatGPT. If you want to write with AI without losing yourself, use Levee.
The choice is honestly not that hard.
