Does the job

Pretty happy overall. Automatic punctuation and profanity filtering just works and customization with phrase hints and adapted models. Best accuracy often needs tuning per use case can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Years in this space

I've evaluated a lot of these over the years. What stands out here is automatic punctuation and profanity filtering — handled better than most — and real-time streaming and batch options. Worth the time if this is your use case.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on domain-specific and telephony models, and real-time streaming and batch options caught me off guard. Requires technical setup and API knowledge is why this isn't a perfect score, still, I'd recommend giving it a real trial.
