Key Points

  • The author is building a mobile app (Android + iOS) that lets you search your phone using natural language queries and semantic search across photos, screenshots, PDFs, notes, documents, and voice recordings.
  • The app is designed to be fully offline and private, so nothing leaves the device.
  • Current phone search is limited to file names or exact words, which makes it hard to locate items like a 'photo of whiteboard architecture' or 'OTP backup codes.'
  • Before deep development, the author is asking the community whether a private on-device AI search would be useful.

Our phones store thousands of photos, screenshots, PDFs, and notes, but finding something later is surprisingly hard.

Real examples I run into:

- “Find the photo of the whiteboard where we wrote the system architecture.”

- “Show the restaurant menu photo I took last weekend.”

- “Where’s the screenshot that had the OTP backup codes?”

- “Find the PDF where the diagram explained microservices vs monolith.”

Phone search today mostly works with file names or exact words, which doesn’t help much in cases like this.

So I started building a mobile app (Android + iOS) that lets you search your phone like this:

- “photo of whiteboard architecture diagram”

- “restaurant menu picture from last week”

- “screenshot with backup codes”

It searches across:

- photos & screenshots

- PDFs

- notes

- documents

- voice recordings

Key idea:

- Fully offline

- Private (nothing leaves the phone)

- Fast semantic search

Before I go deeper building it:

Would you actually use something like this on your phone?
