3.9 out of 5
Scored by a Toolio reviewer after real useOur verdict
SummifyYT scans a YouTube video's comments and produces a summary so you can catch the general reaction without scrolling through hundreds of replies. A GPT-4 option can be switched on, and you can set your preferred summary language, but you have to already be logged into ChatGPT for it to work at all. Ratings sit at 2.8 out of 5 across a small sample, suggesting the experience is inconsistent for at least some users.
