QuillBot Proのヒントとショートカット

After two years of daily use, these are the habits that save time.

Saving time here means fewer edits later, not skipped review.

キーボードショートカット

アクション	ショートカット
Rephrase highlighted text	Ctrl + Enter
Undo a rewrite	Ctrl + Z
Freeze a word or phrase	Click the word, then Freeze
Open the next suggestion	タブ

ほとんどの人が見逃す隠れた機能

Word freezing: Lock brand names and technical terms so the paraphraser never swaps them.
Compare modes: View two rewrites side by side and pick the stronger sentence structure.
QuillBot Flow: The unified 2026 workspace keeps every tool inside one document.

Here are the benefits that keep me paying for it:

QuillBotでよくある間違いとその回避方法

Mistake #1: Pasting Whole Documents at Once

❌ 間違い: Dropping a 2,000-word draft in and accepting whatever comes back.

✅ 右: Rewrite one paragraph at a time and read every new version.

Mistake #2: Skipping the Citation

❌ 間違い: Rewording else’s work and treating the rephrased text as your own.

✅ 右: Cite the original source, even after paraphrasing it completely.

Mistake #3: Trusting the Output Blindly

❌ 間違い: Publishing a blog post without checking whether the meaning survived.

✅ 右: Read the output aloud, since awkward phrasing is obvious when spoken.
