Key features	Sentence-level highlighting rather than a single score Calibrated confidence scores Detects partially AI-written passages in mixed text 10,000 characters per scan with no account Browser extension and free API at 1,000 requests a day	Sentence-by-sentence AI-detection with color-coded highlighting Readability scoring alongside detection Multi-model detection - GPT, Claude, Gemini, and more Multi-language support Free, unlimited checks with API integration
Pros	Sentence-level output shows where a judgement came from Genuinely free with a generous API allowance and no account needed Specific privacy statement: not stored, not shared, not used for training	Genuinely free and unlimited, no paywall on core detection Named, specific model coverage rather than a vague "detects AI" claim API access supports integrating detection into an existing workflow
Cons	AI text detection is not reliable enough for consequential decisions 99.2% accuracy is not a figure any detector has demonstrated in the wild False positives fall hardest on non-native English writers	AI-detection accuracy is inherently imperfect and improves-then-degrades as generative models evolve No paid tier means no stated commercial support or SLA Results should inform judgment, not serve as sole proof of authorship
Company	Buildly LLC	ZeroGPT.cc
