Assembly AI

AssemblyAI provides speech-to-text and audio intelligence APIs that convert spoken audio and video into accurate text transcriptions. The platform is built for developers and engineering teams who need to embed transcription, summarization, and audio analysis features into their own applications. Its models support tasks such as speaker diarization, sentiment analysis, content moderation, entity detection, and topic classification. AssemblyAI also offers Large Language Model-based tools, including LeMUR, which allows developers to query and extract insights directly from transcribed audio data. Customers span industries like media, call centers, virtual meeting software, and telehealth, using the APIs to automate workflows that previously relied on manual transcription and review.
