NextGenUp is a free, open-source AI upscaler. Sharpen photos to 8K and video to 4K , restore faces, and clean up noise — all locally, with no cloud, no subscription and no watermark. An open alternative to Topaz Gigapixel AI and Topaz Video AI. Real-ESRGAN and GFPGAN, bundled and running locally — no setup, no accounts, nothing to configure. Four modes — Quick, Quality, Enhance and Ultra — from a fast preview to maximum detail. Basic and professional AI modes upscale footage frame-by-frame with FFmpeg. GFPGAN v1.4 detects faces and recovers the detail generic upscaling misses. Enhance mode removes noise and blur at the original resolution when you don't need more pixels.

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1.
