FAQs
How accurate is AI detection?
No detector is perfect. We combine model signals with heuristics and show highlights so you can make informed edits — use results as one input, not a final verdict.
What is the minimum text length?
Paste at least 50 characters for a meaningful scan. Longer drafts produce more reliable highlights.
Can teachers or editors use this?
Yes — many users scan student submissions or client drafts before feedback. Pair scores with your own review process.
Does Pro include the humanizer?
Yes. One $10 Pro payment unlocks unlimited access to all heyLoo tools.
