Deep Dive: Key Differences

Rewrite Modes

QuillBot's free tier limits you to two basic modes. Rune offers three—including a dedicated "Formal" mode for professional documents—giving you more flexibility without paying for a subscription.

Tone Adjustment

This is where Rune shines. QuillBot doesn't offer tone customization at any tier. Rune lets you choose between Formal, Friendly, Academic, and Persuasive tones, ensuring your output matches your audience perfectly.

Character Limits

QuillBot's free tier has a frustrating 125-word limit. Rune allows up to 5,000 characters per request, making it far more practical for real-world writing tasks like essays and articles.

Privacy

Rune processes text in real-time and never stores it. QuillBot's privacy policy is less clear, and your data may be used for model training.

QuillBot bombards free users with ads and upgrade prompts. Rune has zero ads—ever.

Use Case Winners

For Students: Rune wins with higher limits and Academic tone.
For Marketers: Rune wins with Persuasive tone and keyword retention.
For Quick Grammar Fixes: Tie—both do this well.
For Privacy: Rune wins—text is never stored.

Conclusion

QuillBot is a household name, but Rune's AI Rephraser offers more features, higher limits, better privacy, and zero ads—all for free. If you're looking for a QuillBot alternative that delivers more value, try Rune's AI Rephraser.
