AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
CallBro is a desktop AI meeting assistant that records and transcribes meetings in real time directly from your device's system audio and microphone, without sending a separate bot to join the call. Because capture happens locally at the system level, it works with any meeting platform, including Zoom, Google Meet, and Microsoft Teams, as well as in-person conversations, and it remains invisible to other participants. CallBro combines the live transcript with the user's own typed notes to generate structured summaries that highlight key decisions, action items, and next steps, and it includes an AI chat that can answer questions about the meeting or draft follow-ups using the full context of the transcript and notes. The product is offered as a downloadable application for macOS and Windows, with Linux noted as upcoming, and the website lists dedicated use cases for lawyers and students alongside general business meetings. Its bot-free, device-only approach makes it relevant for professionals handling sensitive conversations, such as legal client meetings and consultations, where a visible third-party recorder may be undesirable. Pricing varies by plan. Check the official website for current pricing.

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.
