Does the job

Pretty happy overall. Multiple audio input options just works and no complex setup required. but no dealbreakers — I'd recommend it to a friend without hesitating.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on aI-powered transcription engine, and free to use caught me off guard. still, I'd recommend giving it a real trial.

Years in this space

I've evaluated a lot of these over the years. What stands out here is aI-powered transcription engine — handled better than most — and no complex setup required. Limited advanced editing features is my one real gripe. Worth the time if this is your use case.
