Shortlist Ava when real-time captioning for deaf and hard-of-hearing participants matters most, and Substrata when coaching sellers on social dynamics in high-stakes conversations matters most. Run both through a week of actual calls to see which suits your workflow.
AI live captioning and transcription app for accessibility, providing real-time captions for conversations and video meetings.
AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
Ava is a live captioning and transcription service built primarily for deaf and hard-of-hearing users, as well as for organizations that need accessible meetings and conversations. The app captures audio from in-person conversations and from video conferencing tools, then generates real-time captions on a phone, computer, or in the meeting interface. Ava combines automatic speech recognition with an optional professional scribe service for higher-accuracy, ADA-compliant captioning, giving users a choice between fast AI captions and human-assisted transcription. Features include color-coded speaker identification so users can follow who said what, support for many languages, and stored transcripts and summaries after a conversation ends. Through its Ava Connect integration, the service connects with Zoom, Google Meet, and Microsoft Teams, and it is available across mobile (iOS and Android), web, and desktop (Windows and Mac). Ava is aimed at individuals who need accessibility support in daily conversations and meetings, as well as at educational institutions, healthcare providers, corporations, and event venues that must provide compliant real-time captioning without committing to a traditional CART contract. 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.
