Use it every day

Honestly didn't expect to like it this much. Speaker diarization and word-level timestamps is exactly what I needed, and fast, low-latency streaming transcription. I do wish some advanced features limited to higher tiers, but I reach for it almost every day now and it just clicks.

Compared a few options

Evaluated this against two competitors. Where it wins: custom model fine-tuning and supports many languages and accents. Where it lags: some advanced features limited to higher tiers. On balance the feature set — especially speaker diarization and word-level timestamps — justifies the 5 stars for our use case.

Solid for our team

We rolled this out across the team last quarter and fast, low-latency streaming transcription. Custom model fine-tuning fits neatly into how we already work, and custom model fine-tuning removed a step we used to do by hand. but it has held up under daily use.

Use it every day

Honestly didn't expect to like it this much. REST and WebSocket APIs with multi-language SDKs is exactly what I needed, and custom model training for domain-specific accuracy. I do wish requires technical expertise to integrate, but I reach for it almost every day now and it just clicks.

Compared a few options

Evaluated this against two competitors. Where it wins: audio intelligence (sentiment, topics, summarization) and scales for high-volume enterprise workloads. Where it lags: non-English accuracy varies by language. On balance the feature set — especially speaker diarization and word-level timestamps — justifies the 5 stars for our use case.
