I Built a Privacy-First Alternative to Microsoft Recall — Using All 3 Gemma 4 Modalities

This is a submission for the Gemma 4 Challenge: Build with Gemma 4

What I Built

After Microsoft's Recall got torn apart for storing screenshots in plaintext with telemetry phoning home, I thought — the idea is genuinely useful. Knowing what you were doing 3 days ago, finding that one message someone sent you, remembering what you were working on before lunch. The execution was just terrible.

So I built ScreenMind — an open-source screen activity journal that runs entirely on your machine. It captures your screen, analyzes every screenshot with Gemma 4's vision, and builds a searchable, chat-able AI memory of your digital life.

The difference from Recall: nothing ever leaves your computer. No cloud. No telemetry. No "trust us with your screenshots." Everything — capture, analysis, search, chat — runs locally on a single GPU.
