Where each tool wins (and loses).
Every tool has a reason to exist. Here's an honest take on each one.
The only platform that covers all five modalities — text, images, video, speech, and documents — without enterprise pricing. Built for newsrooms, education, and legal teams who encounter AI content in every format.
The most recognized name in AI text detection. Strong for educators catching AI-written essays. Doesn't touch images, video, or speech — and its false positive rate has drawn criticism in academic circles.
Popular with content teams and SEO agencies. Solid text detection, experimental image analysis. No video, no speech, no document scanning. Good for written content at scale.
Long-standing plagiarism detection tool that added AI detection. Good for institutions already using it. Limited to text and basic document scanning. Not built for the multimodal world.
The enterprise multimodal option. Strong accuracy, API-first. But it's built for large platforms with dedicated engineering teams — not schools, newsrooms, or SMBs. The pricing alone disqualifies it for most buyers.
If you only need text detection under $15/mo, GPTZero or Copyleaks work fine. If you need multimodal coverage and have a $1k+/mo budget, Hive is solid. If you need everything at SMB pricing — RealCheck is the only option.
