Symbl.ai is hosting a challenge in December where participants can win a pair of AirPods Pro by auto-generating a summary of their favorite video using the Summarization API. To participate, sign up for a free Symbl.ai account and follow instructions to submit a video and enable summarization. The challenge requires a few minutes of effort, and participants must tweet or post a screenshot with the generated summary text on social media by December 29th to qualify. Two winners will be randomly selected on December 30th.
