AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
AudioPen is a voice-to-text tool that captures spoken thoughts and turns them into polished written notes. You record your voice (or upload an audio file), and AudioPen transcribes the speech, then rewrites it into clear, structured text by fixing grammar, cutting filler words, and organizing rambling input into coherent prose. Rather than producing a verbatim transcript, it reshapes what you said into finished writing in a style you select or train over time, with preset and custom styles available. It supports multiple languages and can transcribe speech in one language while writing the output in another. A SuperSummaries feature combines several notes into a single cohesive summary, and existing notes can be reformatted for different purposes such as emails or to-do lists. Built by independent developer Louis Pereira, it runs across iOS, iPad, Apple Watch, Android, Mac, and a Chrome extension, with Zapier and webhook integrations for sending notes elsewhere. It is aimed at people who think out loud and want to convert informal speech into professional written content.

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.
