@Transcript LOL

I already have another transcription tool, but this one is much better. I love the different features such as the summary, quiz, and chapters. It does a great job of them. I've only done one transcript so far to try it out, but I'm truly impressed and am going to grab another code. A couple things that would make it even better are: - the ability to rename the files and organize them through folders. - the ability to download a copy of the other features as well as the transcript. Copying and pasting it works, but doesn't keep the format.

No other tool quite like this, it's pretty straightforward. Needed to extract a long interview from YouTube and it extracted everything, providing it in different meaningful formats in less than two minutes. Awesome

I’ve tested a bunch of speech recognition tools, and Speechmatics really stands out for accuracy across accents and noisy environments. It’s fast, developer-friendly, and feels reliable enough too. Definitely worth a try if you need robust transcription or real-time voice AI.
