# Noxport Labs — Local-First AI Browser Tools & Evidence-Linked Research Software

> Noxport Labs is an independent software engineering studio developing deterministic, local-first browser utilities, evidence-linked knowledge pipelines, and desktop research workbenches. Our flagship commercial product is **Noxport AI Exporter** (`v3.0.4.226`, Available Now) — a local-first Chrome Extension (Manifest V3) that compiles ChatGPT, Claude, Google Gemini, Perplexity, Grok, DeepSeek, Microsoft Copilot, and Qwen threads into clean Markdown, native OOXML Word (`.docx`), Vector Text PDF, and cryptographically verifiable Professional Audit Packs (`.zip`) with zero cloud uploads and no account required.
