  Hello HN Over the New Year's break, I created semanticvideosearch.com. This can search any video based on meaning and context. I would love to get your feedback on it. What should I change and what can be improved? The preprocessed videos can be search very quickly, while the youtube video links take some time (yt videos also have a upper duration limit due to compute issues). I intend to add search based on the frames of the video soon. I would love to know your thoughts on the demo and any suggestions for improvements. Thanks! PS: the inspiration to create this was to get the 2 mins of…

  Hey HN, I wanted a way to search across multiple YouTube videos at once, find every time someone discusses a topic, compare how different creators explain the same concept, or pull all mentions of a keyword across a channel's archive. The interesting part: it uses Gemini's multimodal capabilities to search visually, not just transcripts. So you can find "the whiteboard diagram" or "when he shows the demo", things transcript-based tools completely miss. Stack: Next.js, Convex, Clerk, Gemini 3 Flash Would love feedback from anyone who works with video content. https://momentclip.com

  After 2.5 years on my side project, it has hit £500/month revenue▲647

  It's been a long slow hog and I almost gave up a few times (more than a few) but when covid hit this year it gave me some time to really focus on my product. There were stupid user journey things that I knew needed fixed. There were some features I knew needed added. And I knew the pricing was wrong. I spent some hardcore time working on these things back in March / April and since then my MRR has continued to grow. My product is SongBox (https://songbox.rocks) - it's an alternative to things like bandcamp and soundcloud for creators who need to share audio files privately.…
