Over the last 7 days, AssemblyAI has answered our automated checks with 100.00% availability and a typical response time of ~62 ms. According to AssemblyAI's official status page, the most recent outage began 2026-08-25 14:55 UTC and lasted 6m (severity: degraded). It was reported as "Increased latency for Universal 3.5 Pro Realtime model".

AssemblyAI offers speech-to-text APIs with speaker labels, sentiment, and summarisation, used in call analytics and meeting tools. Because most work is asynchronous, an outage often means transcription jobs accepted but never completing, or real-time streaming sessions dropping while the upload endpoint keeps returning success.

AssemblyAI is also searched for as Assembly AI.

What to do if AssemblyAI is down for just you

  • Reload the page or restart the app — AI tools often recover from transient session errors.
  • Sign out and back in; an expired auth token can look like an outage.
  • Check your API usage or rate limits if you're calling it programmatically.
  • Try a different network — some corporate or school networks block AI endpoints.
