Hachi is an AI tool developed by Raman Labs to enhance the search experience across images and videos using natural language processing. It allows users to index their videos and images once, and then make text queries to quickly and accurately retrieve specific data.

In addition to this, Hachi features face recognition technology, enabling users to tag and search image collections using a distinct face. This tool is privacy-focused; all operations, including face recognition, are executed locally on the user's device, making it solely offline and private by nature.

Hachi also offers a unique feature to search across all indexed images and videos with a single text query. It operates as a self-hosted web application on the user's device with no reliance on an internet connection.

The tool delivers a fast and efficient interface to search across various forms of media and aims to be accessible and useful on a consumer-grade CPU.
