AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
Anarlog is an open-source, local-first AI meeting notetaker developed by Fastrepl, Inc., the team behind the project previously known as Hyprnote and Char. It is positioned as an open-source alternative to cloud meeting-notes tools and is designed for people who want to keep meeting data under their own control. Instead of sending a bot into a call, Anarlog captures system audio directly on the user's computer, transcribes it locally, and merges the transcript with short notes the user jots down during the meeting to produce structured, editable summaries with action items. Audio, transcripts, and notes are stored as files on the local disk rather than in an external service, and users can choose between running local AI models or supplying their own API keys for cloud processing. The application is available for Apple Silicon Macs and its codebase is published on GitHub under a GPL license, so it can be inspected, forked, and self-hosted. Anarlog is best for engineers, privacy-conscious professionals, and teams that want bot-free meeting notes with full ownership of their data. Pricing varies by plan.

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.
