More than a text checker
DOSafe combines a self-hosted multimodal model, deterministic provenance checks, and on-chain proof into a single trust layer for any content.
Multimodal detection
Detect AI-generated text, images, audio, and video — all in one tool. Most competitors only handle text. DOSafe uses a single self-hosted multimodal model to analyze any content type.
On-chain verified results
Every detection result is recorded on DOS Chain — a tamper-proof, verifiable audit trail. Share a link to any result that anyone can verify independently, without trusting DOSafe.
201 languages
Natively multilingual — no translation step. DOSafe detects AI content in Vietnamese, Chinese, Thai, Indonesian, and 197 more languages. Built for a global audience.
Risk scores, not binary labels
AI detection is probabilistic — not a yes/no. DOSafe shows a confidence score with explanation: what signals triggered, how confident, and what to do next. No false certainty.
API access for developers
Integrate AI detection into your app in minutes. OpenAI-compatible endpoint, pay-as-you-go pricing via DOS AI. Build content moderation, trust scoring, or review pipelines with a few lines of code.
C2PA provenance check
When content carries a C2PA cryptographic signature (from Adobe, Canon, Nikon, and major media organizations), DOSafe verifies it first — 100% accurate provenance, no AI guesswork needed.
Build trust into your product
Add AI content detection to your platform in minutes. Pay per verification, no subscription required for API access.

Frequently asked questions
How accurate is DOSafe?
DOSafe runs a multi-layer detection pipeline — combining statistical signals, zero-shot model analysis, and a final review by our own hosted multimodal model. This layered approach catches what single-method detectors miss. No AI detector is perfect; we always return a confidence score, not a binary label. Treat results as risk signals, not ground truth.
Is it really free?
Yes. Text and image detection is free with no signup required. Free users get 10,000 words of detection per month. For higher volume or API access, see our paid plans.
Does DOSafe store my content?
Content submitted for analysis is processed and immediately discarded. We store only the detection result score and a hash on-chain — no raw text, images, or personal data. See our privacy policy for details.
What does "on-chain verified" mean?
Every detection result generates an on-chain record on DOS Chain with a unique attestation ID. Anyone can verify the result independently — even if our servers go down. This is the tamper-proof audit trail no centralized competitor can offer.
Can I use DOSafe via API?
Yes. API access is available through DOS AI (dos.ai). Get an API key and call our detection endpoint with any content type. We charge per verification with no monthly minimum.
What languages are supported?
201 languages — including Vietnamese, Chinese, Japanese, Korean, Thai, Indonesian, Arabic, and all major European languages. Our model handles all languages natively without a separate translation step.
How is DOSafe different from GPTZero or ZeroGPT?
Three key differences: (1) Multimodal — we detect AI in images and video, not just text. (2) On-chain proof — every result has a verifiable, tamper-proof record. (3) Multilingual — 201 languages natively vs. English-focused competitors.
Can I detect AI-generated images?
Yes. Upload any image and DOSafe runs multiple checks: cryptographic provenance verification, metadata analysis, and visual inspection by our hosted model. You get a confidence score and a breakdown of what signals triggered.
