最近对网站进行了重构，做成了免费的视频工具站：[ArtPlayer Tools]( https://artplayer.org/tools/) 主要是围绕着 ffmpeg.wasm 和 mediabunny 实现的一些可以直接在浏览器里用的视频/音频工具，常用的有： - 视频压缩：[Compress Video]( https://artplayer.org/compress-video/) - 视频裁剪：[Crop Video]( https://artplayer.org/crop-video/) - 视频合并：[Merge Video]( https://artplayer.org/merge-video/) - 视频尺寸调整：[Resize Video]( https://artplayer.org/resize-video/) - 视频旋转：[Rotate Video]( https://artplayer.org/rotate-video/) - 视频调速：[Change Video Speed]( https://artplayer.org/change-video-speed/) - 添加文字到视频：[Add Text to Video]( https://artplayer.org/add-text-to-video/) - 添加水印：[Watermark Video]( https://artplayer.org/watermark-video/) - 提取字幕：[Subtitle Editor]( https://artplayer.org/subtitle-editor/) - HLS 转 MP4：[HLS to MP4]( https://artplayer.org/hls-to-mp4/) - 音频可视化：[Audio Visualizer]( https://artplayer.org/audio-visualizer/) 大部分工具都是本地处理，文件不会上传到服务器。最开始是因为自己偶尔要处理一些视频，开剪辑软件又有点重，在线工具又担心隐私，所以就慢慢做成了一个站。 目前还在持续完善，体验肯定还有不少粗糙的地方，比如不同浏览器的兼容、移动端操作、长视频性能之类的。 网站： [ArtPlayer Tools]( https:

Show HN: Diff two versions of an AI agent and catch silent permission changes

I collect records and I build apps in my spare time (and listen to records while I build apps), and this is what happens when those two things run into each other. Many people post photos of what they have spinning on their turntables on social media, and most never get any engagement. It occurred to me that people might want a better way to do this, and bringing them together in a niche social site might help. So I made Wax Spinner. Connect your Discogs (the de-facto vinyl collector's catalogue) account, post whatever you're playing with an optional note, and it lands in a feed where people can like it and comment. You can also browse anyone's full collection on their profile, and filter the feed by genre, pulled straight from Discogs metadata. The conversation and the discovery are the primary purpose. The details this crowd might find interesting: every spin generates its own OpenGraph share card on the fly, with cover art, artist, year, and notes rendered server-side and cached

I like doodling, and I like character animation. I made a little tool that can animate your hand drawn characters and put them into an animated meme. It's free, there's no login needed, and it uses an animation pipeline (not generative AI) to create the outputs. Works on desktop and mobile. If you give it a try, I'd love to hear your feedback. Thanks!

Scout is the best tool for finding activities for your child. I built this to solve my personal pain point. Currently the best solutions are wordpress blogs where people manually aggregate this information. But human-run blogs can't possibly find every event, they don't know what my child's interests are or what's near my home, so my wife & I would spend hours just learning what we can do with our child. Scout is totally different. Our Agents intelligently crawl the web and find everything in a specific geographic region. We're staring with Seattle, where I live. Scout event has an "inclusivity" filter which lets you find events that are sensory friendly, ASL/assistive listening/captioning, LGBTQ+ & trans affirming, wheelchair accessible, etc. My favorite feature is the daily email with a curated list of events for you. This week I've gone to 2 events based on those emails alone. Please take a look and give me your feedback! demo: https://youtu.be/6wEVtp7-wV4 The link above is

Show HN: Durable AI agents without the workflow engine

You write 8 text completions and open models score how predictable each word was too them. Predictable => clanker. You can share results with your friends. The scoring checks every word you write against the model's logprobs. Right now I'm using Llama3.1, Deepseek v3 and Qwen3 to keep costs low. I tried to calibrate it so other models (chatgpt/claude) score 100% and interesting human responses score in the 10-30% range. Totally free, no signup
