Reilaa is a small-footprint entrant in an AI detection market that now has dozens of competing tools, and the honest first question for any tool at this scale is whether it's running its own detection model or wrapping someone else's API behind a different interface. Here is how to tell the difference, what Reilaa is likely measuring either way, and how to verify a score instead of trusting a brand name you haven't heard of before.
A crowded field, and not every entrant built its own model
Training and maintaining a detection model that keeps pace with new AI model generations is expensive and requires continuous retuning. Some smaller detector brands build and maintain their own; others license or wrap an existing detection API and add their own interface and pricing on top. Neither approach is inherently dishonest, but it matters for what you're actually trusting when you read a score, because a wrapped tool's accuracy ceiling is set by whichever underlying model it's calling, not by anything Reilaa itself has published.
Check the tool's about or methodology page for any mention of a proprietary model versus a third-party integration.
A detector with no published information at all about its underlying approach is a reason for more caution, not less.
Price alone tells you nothing about accuracy -- free and paid tools in this category both range widely.
What the score is measuring, regardless of the tool underneath
Every detector in this category, wrapped or independently built, is scoring the same two underlying properties: perplexity, how predictable each word is given what came before, and burstiness, how much sentence length and structure vary across a passage. Human writing tends to be uneven on both measures. Model output tends to be smoother, because smoothness is a direct consequence of what the training objective optimizes for.
The full mechanism, shared across every detector regardless of brand, is explained in how ChatGPT detectors work.
How to verify a Reilaa score before trusting it
Run a passage with a known origin, human-written and AI-generated versions of the same topic, through Reilaa and see whether it separates them correctly. Then run the identical pair through a second, more established detector. If the two tools disagree meaningfully, that disagreement is more informative than either score alone, because it tells you the result is sensitive to which tool you happened to pick rather than reflecting something stable about the text.

The false-positive risk is category-wide, not tool-specific
Non-native English writers and anyone with a formal, technical, or unusually consistent writing style face elevated false-positive risk on any detector in this category, including Reilaa. This isn't a defect unique to smaller tools, it's a known limitation of scoring statistical uniformity as a proxy for machine authorship.
The false-positive patterns that repeat across the category are covered in are AI detectors accurate.
If your text gets flagged
A word-swap pass changes vocabulary, not the sentence-length variance and structural predictability that detectors actually score, so it rarely moves the number in any meaningful way. Structural rewriting is what changes the underlying signal.
Our free AI Humanizer rewrites at the structural level rather than swapping individual words.
Frequently asked questions
Is Reilaa a real AI detector or a wrapper for another tool?
There's no independently verified answer to this without Reilaa publishing its own methodology. Check the tool's about page for any disclosure, and treat the absence of one as a reason for extra verification rather than assuming either way.
How accurate is the Reilaa AI detector?
It's almost certainly using the same perplexity and burstiness signals as every other text detector, with accuracy that depends on how much tuning has gone into the specific implementation. Verify any score against a second, more established detector before trusting it.
Is Reilaa free to use?
Pricing for smaller AI detection tools changes often and isn't reliably documented outside the vendor's own site, so check current terms directly.
