Hachi

Hachi is a self-hosted, offline AI tool for natural language search across personal videos and images. It indexes your media locally, supports face recognition, and runs on consumer-grade CPUs without sending data to the cloud. A free version is available on GitHub, with a paid upgrade for face search and support.

Hachi is a self-hosted web app that lets you search your personal videos and images using natural language. Instead of manually scrolling through folders or tagging files by hand, you type a description of what you are looking for and Hachi returns the matching scenes, objects, or people. It also includes face recognition that can find a specific person across an entire image collection. The tool runs entirely on your own machine, with no internet connection required, so your media never leaves your device. Under the hood, Hachi builds a local index of your videos and images the first time you add them. Once indexed, searches are fast and work across the whole library, not just one file at a time. For videos, you can search while playback is running, which is useful for finding a particular moment in a long recording. The face recognition feature is also fully local, letting you search for yourself or loved ones without uploading anything to a server. The product is aimed at individuals and small teams who want a private, offline way to manage large media collections. It suits photographers, videographers, researchers, and anyone who values data privacy. Because it is self-hosted, you need a machine with a quad-core CPU supporting AVX2 instructions and at least 4GB of RAM, running an x86_64 architecture. Setup is more involved than a typical cloud service, but the trade-off is complete control over your data. Hachi is open source under the AGPLv3, with a free version available on GitHub and a paid version sold through Gumroad. The free tier covers live video search, natural language search across indexed videos and images, and unlimited indexing. The paid version adds face recognition across indexed images, improved video search, email support, and one year of free updates. The paid license is for personal, non-commercial use only. Hachi competes with cloud-based media search tools by offering privacy and offline operation, though it requires more technical setup and lacks some polish of commercial alternatives.
