AiRxiv vs Westlake University AiraXiv: Free AI Paper Review for Everyone
The AI Paper Review Revolution: Two Platforms Compared
In September 2025, Westlake University's NLP lab launched AiraXiv and DeepReview, an innovative AI-powered academic paper review system. But there's another platform that's been helping researchers even longer: AiRxiv - a completely free, publicly accessible AI paper review tool for researchers worldwide.
If you're searching for "AI paper review", "free paper review online", or "AiraXiv alternative", you've come to the right place. Let's compare these two platforms and see which one is right for you.
What is Westlake University's AiraXiv?
Westlake University's Natural Language Processing lab (WestlakeNLP) created:
- AiraXiv: An open preprint platform for AI-generated academic papers
- DeepReview: An AI reviewer that simulates human expert thought processes
DeepReview uses a multi-stage review process:
- Innovation Verification: Checks novelty against existing literature
- Multi-dimensional Assessment: Evaluates quality across multiple criteria
- Reliability Verification: Validates research methodology
Sounds impressive, right? It is. But there's a catch...
