What it does
CapFlow Studio allows creators to add AI-powered captions to their videos automatically with Whisper AI. It's mostly free, there are no uploads, and it runs ENTIRELY in your browser via WebAssembly. What’s inside: 100% Private: Zero uploads. Pro Styles: Dozens of unique styles, effects, and presets. Accuracy: Full control over word-level timing and highlights. Flexible: Export as MP4, SRT, VTT, or TXT.
Add captions to your videos automatically with Whisper AI — free, no uploads, runs in your browser. Word-level timestamps, 17 animations, 7 glow effects.
Auto-captions for TikTok, Reels & Shorts. Upload your video, get your captions, export and post. Drag the slider to reveal how CapFlow Studio's editor transforms raw footage into viral captioned clips. Word-level highlights, animated text, minimal effort. Built for creators who move fast. No servers, no queues, no account. CapFlow Studio was built because other caption tools either upload your videos to a server or charge for features that should be free. So, we made one that does none of that. We value your privacy. Your video never leaves your device. No subscription required to start. No sign-up. No credit card.

All I wanted was a simple way to auto-generate captions for my videos—no paywalls, no upload limits, no “surprise, now you need a subscription” popups. As a broke small creator and podcaster, I wasn’t about to drop a pile of cash on tools that watermark my stuff and send my files who-knows-where. So I built my own. I made it free, offline-first and available for Mac (Apple Silicon). Just drag in your video, and it spits out clean, accurate subtitles using the local OpenAI’s Whisper model you choose. What’s the deal? - Animated subtitles that don’t…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
