It's clear the creators of this tool have run YouTube ads before; they've thought of everything! You can search for monetised videos by placement, keywords, similar videos, and others.

+ One very helpful feature is being able to search all the videos for a specific channel and copy the URLs for every video, so you can add them in as individual placements in your campaigns. Great timesaver.

+ The tutorials are quick, to the point, and easy to understand.

+ They have an academy section, where you can learn more about YouTube ads -- I'll be going through to brush up on my skills and ensure I haven't missed anything!

+ They've partnered with wave.video (another great AppSumo-listed software) so you can create your ads inside the Biteplay platform.

+ They already have some great tools, but it also looks like they have lots of other things in development -- there's a few "coming soon" sections.

- Minor thing: When I went to search for similar videos to a particular video URL, I wanted to find ones from different youtube channels. However, only similar videos from that same channel appeared. There is no way (yet) to exclude particular channels in this search function.
