Show HN: We built a tool to dub any video in the original voice in 40 languages We kept seeing the same problem: creators make great content but the moment they dub it into another language, everything falls apart. Robotic voice. Music gone. Meaning lost. Lips not matching. So we built Vaani. Whatever language you create in, wherever you are in the world, your content can reach a global audience. We clone your voice, match your gestures, preserve your music, and optionally sync your lips to the new language. 10+ Indian languages, 20+ global languages, all in minutes. We built it for 2 reasons: So creators never have to sound like a robot in another language again So the same video you already made can reach a global audience without filming twice Would love your feedback. app.vaani.media https://vaani.media June 7, 2026 at 01:51AM

Show HN: StructOCR – API for parsing global passports, invoices, and containers Hi HN, I built an AI-powered OCR API designed to extract highly structured JSON data from complex documents like global passports, IDs, receipts, and shipping containers. We recently rolled out our Python and Node.js SDKs. Just wanted to share it with the community. https://structocr.com June 6, 2026 at 02:48AM

Show HN: I benchmarked LLM agents on fixing real-world security vulnerabilities https://ift.tt/KVkMXgL

Show HN: I benchmarked LLM agents on fixing real-world security vulnerabilities I built a benchmark with 20 real CVEs across 18 Python projects (Pillow, GitPython, yt-dlp, urllib3, etc). I've run it over 5 LLM agents (3 OpenAI, 2 poolside) and 3 different prompts (full advisory, locate, diagnose) with a total of 300 runs. The agents are tasked to fix security vulnerabilities in a sandboxed environment and they are scored against a hidden security tests from the maintainer's own fix. Best solve rate was 50%. On the other 50%, some fixes are sometimes coherent and pass all regression tests, but vulnerability still present. The main differentiator I found between models is cost: gpt-5.5 at 12× more expensive than gpt-5.4-mini while producing statistically similar results. Within-family performance gaps are small, which points out the difference is likely due to model training data. I also did a power analysis and the task count needed to detect a meaningful within-family edge at ~700.
