Meanwhile, cloud photo search uploads your private files to remote servers.</p> <p>I built <strong>Pipit</strong> 🐦 — an open-source, on-device AI universal search engine for Android.</p> <h3> ⚡ Key Features: </h3> <ul> <li> <strong>Deep Content OCR</strong>: Searches <em>inside</em> PDFs, receipts, and screenshots using on-device Google ML Kit.</li> <li> <strong>Semantic Visual Search</strong>: Natural language search across your gallery (<em>"yellow vintage car"</em>, <em>"handwritten grocery list"</em>).</li> <li> <strong>Unified Search Bar</strong>: 7 domains in one place (Photos, PDFs, Messages, Contacts, Video, Audio, Apps).</li> <li> <strong>100% Offline &amp; Air-Gapped</strong>: Runs quantized Google LiteRT multimodal models directly on your phone's silicon. Zero cloud, zero tracking.</li> <li> <strong>Sub-50ms Latency</strong>: Accelerated via local Vulkan GPU/NPU delegates.</li> </ul> <p>Source code and release APKs are available on GitHub:<br> 👉 <strong>Repository</strong>: <a href="https://github.com/sanjay434343/Pipit" rel="noopener noreferrer">https://github.com/sanjay434343/Pipit</a></p> <p>I'd love your feedback, critiques, and ideas!</p> android opensource ai flutter
