QuillBot is the most popular paraphrasing tool online, and its sentence rewriting capabilities are its core feature. The free tier offers Standard and Fluency modes with a 125-word limit. The premium tier at $9.95 per month unlocks Creative, Formal, Shorten, Expand, and Academic modes with no word cap.
Modes vs. Intelligence
QuillBot gives you explicit control over output style through mode selection. Want it shorter? Pick Shorten. More formal? Pick Formal. Txtory takes a different approach — the LLM reads your sentence, understands the context, and rewrites it naturally. There is no mode picker because the model adapts automatically. For users who want precise control, QuillBot’s modes are useful. For users who want quick, natural rewrites, Txtory’s simplicity wins.
The 125-Word Wall
QuillBot’s free tier caps input at 125 words — roughly two sentences. For quick single-sentence rewrites, that is fine. For rewriting a paragraph or longer passage, you either pay for premium or paste in chunks manually. Txtory imposes no word limit, which makes a practical difference for anyone working with text longer than a tweet.
The Bottom Line
QuillBot is the better tool if you want multiple rewriting modes and are willing to pay for unlimited access. Txtory is the better tool if you want fast, unlimited sentence rewriting without restrictions.
