High Performance

Everything you need to analyze files

Stop building fragile regex parsers. Use a battle-tested API designed for heavy I/O workloads.

Instant Extraction: Powered by Go, our parser handles files in memory with zero-copy overhead for sub-millisecond responses.
Security First: We calculate SHA-256 checksums automatically, verifying file integrity before you even process content.
30+ Formats: From PDFs and Docx to rare binary formats. If it has magic bytes, we can identify it.

Advanced Analysis

AI & Screenshot Detection

Don't just detect file types. Understand the content. Our API automatically analyzes images to detect signs of AI generation and screenshot patterns.

AI Generation Detection.: Identifies signs of AI-generated content by analyzing EXIF data presence, noise patterns, and compression artifacts.
Screenshot Classification.: Distinguishes valid photography from device screenshots using resolution heuristics and metadata analysis.
Rich Metadata.: Extract granular details like dimensions, color models, MIME types, and secure SHA-256 checksums.
