Key differences

Different tools for different jobs

Grammarly is a writing assistant that catches errors and suggests improvements as you type. ToneSwap is a rewriter that transforms finished text into your personal voice. They solve different problems.

ToneSwap owns voice matching

Grammarly added a "voice profile" feature in 2023, but it is secondary to their core grammar-checking product. ToneSwap is built entirely around learning your voice. It is the core product, not an add-on.

Outcome-based vs error-based

Grammarly tells you what is wrong with your writing. ToneSwap takes what you wrote and rewrites it for a specific outcome: Work Email, Pitch, Quick Reply. You get finished text, not a list of suggestions.

Grammarly has a bigger toolkit

Grammarly covers grammar, spelling, tone detection, plagiarism, and works in 6 languages. If you need a full writing assistant, Grammarly does more. ToneSwap is focused and does voice-matched rewriting better.
