Sewkal vs QuillBot — Which Shows You More?

Both tools rewrite text with AI. The key difference is transparency: Sewkal shows a per-sentence fidelity score and a word-level diff on every change, so you know precisely what was altered. QuillBot offers synonym replacement and fluency modes but does not expose a sentence-level similarity score.

Try the editor — paste text and see per-sentence fidelity scoring in action.

Feature comparison

QuillBot provides synonym suggestions, a grammar checker, and summariser. Sewkal focuses exclusively on high-fidelity rewriting with auditability — a sentence-level similarity score, a word-level diff view, and individual accept/reject controls. It does not include a grammar checker or summariser.

Which is right for you

If you want to see exactly what the AI changed and measure how closely the rewrite preserves your meaning, Sewkal's diff view and fidelity scoring give you that visibility. If you want an all-in-one writing suite with grammar checking, QuillBot covers more ground.
