VISAI AI
Bangkok-based AI company behind Vocalog Thai transcription and 4Corners Thai legal research AI
VISAI AI is a Bangkok-headquartered AI-enablement company, spun out of a VISTEC/depa research institute and backed by SCB 10X, best known for two Thai-language products: Vocalog for audio/video transcription and 4Corners for Thai legal research. It is best for Thai lawyers, researchers, and businesses that need Thai-specific transcription or statute search rather than a generic multilingual AI tool; 4Corners has outperformed global LLMs on a Thai legal benchmark. Caveat: coverage is Thai-only, so it does not extend to other SEA languages or jurisdictions.
Judged on regional fit, not vendor glossies.
Built by a Thai government-backed research institute exclusively for Thai-language legal and transcription use cases.
Deep for Thailand only; no products localized for other SEA countries or languages.

About VISAI AI
VISAI AI is a Thai AI-enablement company, officially established in 2022 out of a research collaboration between the Vidyasirimedhi Institute of Science and Technology (VISTEC) in Rayong and Thailand's Digital Economy Promotion Agency (depa), and backed by SCB 10X. It builds production Thai-language AI products including Vocalog, an audio/video transcription and meeting-summarization tool that has passed 100,000 users, and 4Corners (Thai: "สี่มุมเมือง"), a legal research platform covering 3,000+ Thai statutes, codes, and decrees through the open-source Sommai and Somsi legal assistants built on the Typhoon Thai LLM.
Key Features
Best For
Southeast Asia Fit
VISAI AI grew out of a Thai government-backed research institute (VISTEC and depa) and focuses exclusively on Thai-language AI, most notably legal research over the Thai statute corpus, where its 4Corners platform scored higher than ChatGPT, Claude, and Gemini on the Thai NitiBench legal benchmark. That Thai-specific depth, plus SCB 10X backing, differentiates it from global LLM products that lack the same coverage of Thai law and financial regulation.
