AI Content Detection
APIs for Developers & Platforms
Integrate scalable AI detection and content verification directly into your applications using secure, developer-friendly APIs for text analysis, with document and image support in the web app (AI video detection is coming soon).
Complete AI Verification API Suite
A robust, highly accurate multi-modal developer toolkit designed to process visual and textual content formats.
AI Text Detection API
Analyze text for AI-generated patterns across ChatGPT, GPT-5, Claude, Gemini, and other language models.
AI Document Detection API
Upload and scan PDF, DOC, and DOCX files for AI-generated content and authenticity analysis.
AI Image Detection API
Identify AI-generated visuals, manipulated images, and synthetic media using advanced image analysis.
AI Video Analysis API (Coming Soon)
Video and deepfake detection is not available yet. Image deepfake checks are available today.
Readability Rewriter API
Rewrite text for clarity and tone through an API, with the same daily limits as the web tool.
Batch Processing API (Planned)
Not available yet. Today each API call checks one piece of content; contact us if you need high volumes.

Start Integrating in Minutes
Use clean API documentation, SDK examples, and simple request structures to integrate AI detection into your product quickly.
// Illustrative example — real scores depend on your text
const res = await fetch(API_URL, {
method: "POST",
headers: { "x-api-key": "YOUR_API_KEY" },
body: new URLSearchParams({ content: "Your text here" })
});
const result = await res.json();
console.log(result.ai_probability, result.verdict);
// e.g. 85 "Likely AI" (a probability, not proof)REST API with cURL, JavaScript, Python and PHP examples in the docs. Official SDKs are planned.
Built for Real-World AI Verification Systems
Scale verification rules across diverse workflow engines, HR portals, sitemaps, and content storage structures.
EdTech Platforms
Analyze assignments, essays, and academic submissions for AI-generated content within LMS modules.
HR & Recruitment
Verify resumes, cover letters, and candidate-generated writing to ensure authentic skills vetting.
CMS & Publishing
Detect AI-generated articles and synthetic media before publication to preserve organic content rankings.
SaaS Applications
Integrate AI verification directly into content moderation systems and automated text processing pipelines.
Enterprise Compliance
Support governance, risk analysis, and digital authenticity workflows at scale to prevent misinformation risks.
Secure & Privacy-Focused API Infrastructure
Content sent to the API is used only to produce the result and is not saved by ProofAI. To analyse it we send it to the AI model providers listed in our privacy policy. We keep a record of each call (date, type and score, not the content) for usage limits and billing.
HTTPS Encryption
HTTPS/TLS via Cloudflare.
Domain-Based Rules
Secure keys to specific domains.
Secure API Keys
Keys are stored only as hashes.
Content Not Saved
Only a record of each call is kept.
Rate Limiting
Per-plan limits and request rate limits.
Scalable AI Detection Infrastructure
Designed for startups, enterprise platforms, and large-scale workflows requiring reliable AI verification at scale.
