Streamr accomplishes its purpose. But the set up isn't easy as they claim it to be on their website. I was finding myself looking at their help center page multiple times to solve the errors I was getting when trying to transcribe a video. Luckily, they had a help center and actual steps on how to solve these errors, but it wasn't as simple as clicking next.
It isn't explicitly mentioned that you are required to create a Google Cloud account for the Streamr to work at all. If you don't thoroughly read the comments on here or their website, you won't be aware of this. Although you need a Google Cloud account for this software to work, I did find it was affordable compared to competitors if you don't plan to use it at a large scale. But isn't clear how much it will cost to use Google Cloud after their 90-day trial/$300 credit. Another thing to note is that the software writes and stores all the transcription data in a bucket (Google Cloud storage) which I don't even know how much will cost me to have.
The interface of the software is easy to use and get a hang of. The subtitle customization is limited, but enough to get the job done. An inconvenience I noticed is that the Streamr doesn't have an option to remember your email or password when starting up the program after a boot, so you need to retype your email and password every time you boot up your computer and want to use Streamr. I also think it would be nice to have an option to customize the number of lines and characters you would like per caption.
Overall Streamr is a helpful tool with about 89% accuracy in the transcription. It significantly reduces the time needed to be spent transcribing a video manually. Transcription results though, isn't provided through Streamr as it is coming from Google's own speech-to-text AI which is also found on YouTube auto captions. For the price that it is being offered Streamr is ok.
