AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
CLOVA Note is an AI-powered meeting-minutes and voice-transcription service from Naver Corporation, one of South Korea's largest internet companies. First introduced in 2020 and officially launched as CLOVA Note, it lets users record meetings directly on a PC or mobile device, or upload recordings, and then automatically converts the speech to text using Naver's own voice-recognition technology. It applies speaker diarization to distinguish between different participants and uses natural-language processing, including Naver's HyperCLOVA model, to produce summaries, surface meeting topics, suggest next steps, and highlight key points paragraph by paragraph. CLOVA Note supports multiple languages including Korean, English, Japanese, Simplified Chinese, and Traditional Chinese, as well as a multilingual recognition model for mixed-language meetings. It works across smartphones, tablets, and PCs with notes synced across devices, and lets organizations register industry-specific terminology and company names to improve recognition accuracy. It is particularly popular in South Korea and across Asia. CLOVA Note is best for individuals and teams in the region who need accurate Korean-language meeting transcription and AI-generated minutes.

Substrata is an AI sales coaching and deal intelligence platform that takes a different angle from typical conversation intelligence tools: rather than focusing on transcription and summaries, it analyzes the social and emotional signals beneath sales conversations. Its core function is to model buyer psychology, attitudes, and momentum across interactions to help professional dealmakers understand intent and power dynamics. A central component is SoundWave, a real-time conversational analytics engine that listens to sales calls and analyzes voice tone, pace, pauses, interruptions, and the push-pull of social dynamics, surfacing the why behind what is being said rather than just the words. Substrata applies this signal analysis across conversations and email exchanges to gauge buyer sentiment and engagement, giving sellers and revenue leaders a read on how deals are actually progressing. The platform is aimed at B2B revenue professionals and leaders, and is positioned for smaller and mid-sized dealmaking teams that want behavioral insight into negotiations and high-value conversations. It has been recognized as a high performer across sales coaching, AI sales assistant, conversation intelligence, sales analytics, and revenue operations categories. Pricing varies by plan.
