FAQ

Is Aithor.com free?

Aithor offers a freemium model. Many features are available for free with sign-up, including limited paper generation and word allowances for tools like Humanizer or Paraphraser. Paid 'Pro' plans offer unlimited priority access to all features.

How does Aithor compare to general-purpose AI models like ChatGPT or Claude?

Aithor is specifically adapted for academic purposes, focusing on formats, citation styles, and academic discourse. Unlike general LLMs that may invent sources, Aithor accesses a database of over 10 million peer-reviewed, verifiable sources. Its Humanizer also aims to bypass AI detection, which general LLMs do not offer.

Is Aithor.com's AI output truly undetectable?

Aithor states that 'Nothing is 100%'. Most tests in English and Spanish returned around 85% human-written scores when the Humanizer is applied. It aims to achieve this quickly, though some cases may require reruns. The company acknowledges that 100% undetectability is an exaggeration due to how AI detectors work.

What types of texts can I write with Aithor?

Aithor helps with research, literature reviews, case studies, reports, essays, and creative writing by providing structure, credible sources, and citations. Users can personalize the experience with the AI writing assistant.

How do refunds work for Aithor subscriptions?

Non-EU residents can request a full refund within 7 calendar days of purchase if they have not exceeded a 10-time 'tryout threshold'. If fewer than 10 uses, a prorated fee may be deducted. EU residents can withdraw within 14 days, but waive this right if they pass the tryout threshold.

Use Cases
