Vext Labs, Inc.

Vext Labs is an AI research company and product studio building verifiable AI systems for researchers and organizations that need auditable AI work. Its flagship product, JUWEL OS, is a conversational AI interface designed to handle complex, multi-step workflows and produce what Vext calls durable runs with receipts, signing material actions onto a record you can verify independently. That verification layer, STOA Receipts, is built so the checker is not the vendor, meaning results can be confirmed offline without trusting Vext's own servers. On the research side, Vext Labs publishes public papers on AI capability growth (which it calls capability accretion) and labels each claim by scope such as toy, measured, proven, or proposed, and it archives failed experiments alongside successful ones. On Product Hunt the company also described Theron, positioned as a council of domain specialists that deliberate per query on an owned foundation model, and AE OS, a company-facing AI OS with Slack, Gmail, and GitHub connectors. JUWEL OS is currently in beta with private pilot and dogfood testing, so broad availability is limited.

Researchers and organizations use Vext Labs' JUWEL OS to run complex AI workflows and get verifiable, offline-checkable records of AI work.
