What is AssemblyAI?

AssemblyAI provides a cloud API for automatic speech recognition (ASR) and audio content analysis. Developers can send audio or video files and get back transcriptions, along with insights like detected topics, summaries, or content moderation flags. It supports real-time transcription as well. AssemblyAI’s models are known for high accuracy and are trained on a diverse range of accents and acoustic scenarios. While it's primarily a developer service (no end-user app), its technology powers many transcription tools and AI note-taking apps. Pricing is pay-as-you-go per minute of audio with a free tier for testing.
