    Hi HN, I’ve spent the past few months building https://meme-gen.ai – a tool that transforms any photo into an AI-generated meme video. It’s built for simplicity: no need to write prompts, tweak settings, or have any experience with AI or video editing. Just upload a photo, and our system instantly animates it into a short, funny video meme. It’s designed to be zero-friction and fun – something you can use in seconds and share in a click.

    Hi HN! Since the launch of JigsawStack.com, we've been trying to dive deeper into fully managed AI APIs built and fine tuned for specific use cases. Audio/video transcription was one of the more basic things and we wanted the best open source model at this point it is OpenAI's whisper large v3 model based on the number of languages it supports and its accuracy. The thing is, the model is huge and requires tons of GPU power for it to run efficiently at scale.
