AI Fraud Detection
AI Fraud Detection for Document-Intensive Workflows
Hesper AI uses large language models and computer vision to detect document fraud that rule-based systems cannot catch. 94% accuracy, sub-80ms response, deployed by 40+ enterprise finance teams.
How AI fraud detection works
Three steps from document submission to actionable fraud verdict. No setup, no model training, no changes to your existing pipeline.
Upload your document
Send a PDF, PNG, JPEG, or TIFF to the Hesper AI /v1/analyze endpoint via a standard multipart POST. Documents up to 50MB are accepted. No preprocessing, conversion, or special formatting required.
AI analysis runs in milliseconds
Our models run pixel-level forensic analysis, font and character consistency checks, LLM-based semantic validation, and metadata inspection simultaneously — returning a result in under 80ms.
Risk score + explainable findings
The API returns a fraud probability score, a risk classification (clean / suspicious / high-risk), and a list of specific anomalies with highlighted regions — so your team always knows why a document was flagged.
What makes Hesper AI different
Purpose-built for the modern fraud landscape, where AI-generated fakes and pixel-perfect edits fool every rule-based system.
LLM-based semantic analysis
Large language models evaluate the internal consistency of financial documents — detecting implausible income figures, mismatched employer details, and AI-generated text patterns.
Pixel-level forensic detection
Computer vision models scan every pixel for cloning artifacts, brightness inconsistencies, and compression anomalies left by editing tools including Photoshop, GIMP, and AI image generators.
Font and typography fingerprinting
We extract and analyse every character, detecting inconsistent font weights, spacing anomalies, and characters that don't match the document's declared font metadata — the hallmarks of text replacement.
Pattern recognition at scale
Trained on millions of real and fraudulent documents, our models generalise to new fraud patterns without requiring manual rule updates or model retraining from your team.
Explainability built in
Every finding includes a natural-language explanation, a confidence score, and highlighted document regions — giving fraud analysts the context they need to act quickly and confidently.
Continuous model improvement
Hesper AI models update continuously as new fraud techniques emerge. You benefit from the latest detection capabilities without any changes to your integration.
