Notta

Notta is a widely adopted AI transcription and translation service in Japan. It supports 58 languages with auto summaries, popular for meeting notes at small teams.

Better Japanese accuracy than Otter and the live EN↔JP translation is genuinely useful in cross-border calls. A default for Japan-facing small teams.

클로바노트

Clova Note is an AI voice recording service developed by Naver. It automatically transcribes and summarizes meetings, lectures, and interviews. With excellent Korean speech recognition, it is optimized for Korean business environments.

For Korean meeting transcription, Clova Note's accuracy is in a different league from foreign STT services — it catches industry terms and proper nouns that others mangle. As a Naver service, data is processed domestically, which can be a meaningful advantage in B2B contracts where data residency matters.

뤼튼

Wrtn is a Korean-optimized AI writing and workflow automation platform. Access ChatGPT, Claude, Gemini and more through a single interface to automate marketing copy, emails, and reports.

For Korean-language AI writing, the ability to compare GPT-4, Claude, and Gemini side-by-side in one interface is Wrtn's standout advantage. It's particularly efficient for repetitive Korean content work like marketing copy and social posts. The value is hard to beat — multiple AI models for just a few dollars a month.

채널톡

Channel Talk is an all-in-one business communication platform combining AI-powered customer support and team messenger. Small teams can deliver enterprise-grade customer experiences through chatbot automation and live chat.

If you need a CS tool for the Korean market, Channel Talk is the de facto standard. Running a separate team messenger alongside a customer chat creates context gaps — Channel Talk solves both in one place. The free tier is genuinely usable for small teams, so there's no reason not to try it.
