Grammarly’s tone feature works differently from what most people expect. It does not rewrite your text in a new tone — it detects your current tone and labels it (confident, direct, friendly, concerned, formal, etc.). The detection is passive: it tells you how your writing sounds, then offers individual word and phrase suggestions to shift that perception.
Detection vs. Transformation
Txtory’s Tone Changer does actual transformation. You select a target tone — formal, casual, confident, empathetic, persuasive — and the AI rewrites your entire text to match. The output is a complete rewrite, not a list of suggestions. For someone who needs to convert a casual Slack message into a formal email, Txtory does the work in one step. Grammarly would guide you through editing each sentence individually.
The GrammarlyGO Factor
Grammarly’s premium AI feature, GrammarlyGO, can rewrite selected passages with some tone awareness. It is closer to what Txtory does but requires a subscription, works on selected text rather than full documents, and offers less granular tone control. Txtory provides more specific tone options and works on the entire text for free.
The Bottom Line
Grammarly is the better tool for understanding how your writing sounds and making incremental improvements. Txtory is the better tool for wholesale tone transformation — when you need text rewritten in a specific voice, fast and free.
