What users say about Assembly AI

Trusted by teams at EdgeTier, Jiminny, and Earmark

EdgeTier

The transcript quality is critical, both for user perception and our AI models. Once you lose trust in transcript accuracy, you erode trust in the product. For text classification, phrase detection, and agent evaluation, the language has to be correct - otherwise, the whole system falls apart.

Jiminny

AssemblyAI has a real high-touch personal service. It's a great partnership and we're very collaborative and get to test new AI models early and work together. And AssemblyAI is really pushing boundaries, helping us create a well-rounded conversation intelligence platform.

Earmark

The cost saving is literally the difference between being profitable or not for us, but beyond the economics, AssemblyAI gave us something invaluable: peace of mind. We can focus on building our product instead of worrying about infrastructure limits.

Mark Barbir
CEO at Earmark

I love how AssemblyAI delivers outstanding transcription accuracy even on noisy or low-quality audio. The SDKs, documentation and code samples made integration into our codebase very easy and almost instantaneous.

The speed difference is immediately noticeable - our users see their conversations transcribed almost instantaneously. It feels so much more responsive than what we were using before.
