A QuillBot Alternative Guided by AI Detection
QuillBot paraphrases by mode, blind to AI detectors. CheckAI shows which sentences still read as AI, then rewrites exactly those — so you reword where it counts and can verify the AI signal actually dropped.
CheckAI is a QuillBot alternative for people whose goal is passing AI detectors: it scores your text at the word and sentence level, rewrites only the lines that read as AI, and lets you re-check the score — rather than paraphrasing the whole text blindly. Free to start with 20 checks daily.

Reword where it counts in 4 steps
Paste your text
Add an AI-written or AI-assisted draft. CheckAI scores it at the word and sentence level.
See which lines still read as AI
A token-level heatmap shows exactly which sentences need rewording — so you do not paraphrase everything.
Rewrite the flagged lines
Rephrase those sentences into natural language while keeping your meaning, or let Instruct do it.
Re-check the result
Run detection again to confirm the rewording actually lowered the AI signal.
Paraphrasing with a target
Reword what reads as AI, keep what already works.
Detection-guided
CheckAI knows which lines read as AI and rewrites those, instead of running your whole draft through a mode.
Keeps your meaning
Targeted rephrasing changes wording and tone, not your ideas, so the paraphrase still says what you meant.
Verify the drop
Check the AI signal before and after each rewrite, so you know the rewording improved it.
Detect and reword in one loop
No bouncing between a detector and a separate paraphraser — do both in the same editor.
Why look for a QuillBot alternative?
QuillBot is a popular paraphraser and grammar tool, great for rewording and polishing in general. But it paraphrases by mode without any awareness of AI detectors — so if your actual goal is to make AI-assisted text read human and pass AI checks, you are rewording in the dark. You cannot see which sentences still read as AI, or whether your rewrite helped.
How CheckAI compares
CheckAI approaches rewriting from the detection side. It first scores your text at the word and sentence level, shows which lines read as AI, and then rewrites exactly those — keeping your meaning intact. Because detection and rewriting share one editor, you can re-check after every edit and watch the AI signal drop, instead of hoping a paraphrase worked.
Targeted beats blind
Rewording an entire passage is slow and risks your meaning. CheckAI lets you paraphrase only the sentences that need it, then verify the result — less effort, less risk, and a clearer outcome than a full blind rewrite.
