Timbel (TIMBEL = Timeless Label) combines 20 years of voice-transcription expertise with in-house AI engines to automate the full spectrum of enterprise work — calls, meetings, consultations, knowledge, and marketing.
We began as a stenography service in 2001 and were the first in Korea to fuse AI with transcription. Built on our own speech recognition engine (HAIV) and real-time voice engine (Brain), we are the proven partner that the most security-critical organizations — the Constitutional Court of Korea, the Financial Supervisory Service, and major banks — chose first.
Ten years of in-house R&D and commercialization behind HAIV, Korea's best-performing speech recognition and synthesis engine. From Korea's first CPU-based end-to-end speech recognition to deep-learning speech synthesis in under one second — the heart of every product we make, completed with our own technology, never leaning on external engines.
Every layer developed in-house, with no reliance on external solutions.
From voice engines to LLM and knowledge, domain understanding, and security — because we built every layer ourselves, we deliver sub-1-second real-time responses, fully on-premises deployment, and world-first patents.
In-house STT and TTS trained on 98,000 hours of Korean, plus a real-time voice agent that responds in under a second.
An LLM tuned directly for work domains and a knowledge engine that produces grounded answers and deliverables.
Field-proven AI that knows your domain, fully on-premises deployment that keeps data inside, and proprietary patents.
