Answers
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.
The fastest way to check AI patterns
Scan, highlight, and fix — with heyLoo's full toolkit behind you.

Answers
FAQs
How does an AI-to-human text converter work?
You paste AI-generated text, pick a tone, and our model rewrites phrasing and structure to sound more natural. We score AI-likeness before and after so you can see improvement.
Will it change my meaning?
The goal is to preserve facts and intent while changing how the text reads. Always review output before publishing — especially for technical or legal content.
How much does Pro cost?
Pro is a one-time $10 payment for lifetime unlimited access to the humanizer and all other heyLoo tools. No recurring subscription.
Can I use the checker after humanizing?
Yes. Open the AI Checker from the homepage workspace or visit the checker tool page to verify your rewritten draft.
Is there a free trial?
Yes — free daily runs without an account. Create a free account for saved history; upgrade to Pro when you need unlimited passes.

- Field-based builder — not 100 random one-liners
- Works in any major chatbot
- Free daily generations
- Humanizer + checker included in Pro ($10 once)
Generate the prompt, run the AI elsewhere, then humanize and verify in heyLoo.
