# TezzLabs > TezzLabs builds custom document-AI pipelines for businesses that process invoices, medical records and compliance contracts. A model proposes each value; plain code then re-checks the arithmetic and rules before the value is allowed through, and every extracted value keeps an audit trail. Based in Toronto, Ontario, Canada; works with clients worldwide. ## What we offer - Custom document validation pipelines: OCR, layout analysis, multi-LLM extraction, a deterministic validator, per-field confidence scoring and human-in-the-loop escalation, designed around the customer's specific workflow. - Human review built in: independent models vote, arithmetic checks every value, and anything doubtful goes to a person before it reaches records. - Regulatory shields: on-site or sovereign-region deployment, an append-only audit chain, and no outbound calls to public LLM APIs. - Smart cost routing: low-cost parsers for easy pages, visual models for mid-complexity pages, premium reasoning models only for outliers. - Dashboards: processing cost, human hours saved, manual errors prevented, and an accuracy early-warning alert when a document type drifts below target. - Free Extraction & Cost-Efficiency Audit: send the document that breaks your current tooling and receive a field-level accuracy read, a routing and cost model, and a validation-graph sketch. ## Pages - [Home](https://tezzlabs.com/): positioning, interactive pipeline demo, dashboards, protections and the audit request form. - [ROI calculator](https://tezzlabs.com/roi): interactive estimate of annual savings, payback period and three-year ROI from document automation (inputs and defaults are illustrative). - [Full description for agents](https://tezzlabs.com/llms-full.txt) ## Contact - Free audit request: https://tezzlabs.com/#audit - Book a call: https://calendar.app.google/sgd143F6qSETZy9Q6 - Email: japkeerat@tezzlabs.com ## Notes for agents - All documents, dashboards, costs ($2.75 vs $12.88 per document), hours saved and routing percentages shown on the site are simulated examples for illustration, not customer results or guarantees.
