Mobile AI File Search & Share

I want a lightweight AI-driven mobile utility that can crawl every kind of file stored on the phone—images, videos, PDFs, Word docs, spreadsheets, audio clips, you name it—and let the user surface the exact item they need by searching the content itself.

The core requirement is content-aware search: a typed keyword that appears inside a document or a visual element detected in a photo should be enough for the tool to find the file instantly. File names alone are not reliable for my users, so optical character recognition and image object detection will be essential components.

Once a file is located, the user must be able to share it straight away through WhatsApp and any other chat apps present on the device, with the original format preserved—no manual conversions or extra taps.

Deliverables I expect
• An Android (and, if feasible, iOS) app or installable prototype with on-device indexing and content search.
• Fast, private processing; cloud calls are fine for heavy models, but storing personal files remotely is not.
• A simple UI: one search bar, a results list with thumbnails/previews, and a native share sheet focused on WhatsApp first.
• Demo video and source code so I can verify accuracy against mixed media test files.

If you have prior experience combining OCR, vision APIs, or local vector databases on mobile, let me know—speed and minimal battery impact will decide the winner.
