What Pixel Dust is

A second brain for everything on your screen.

You no longer need perfect naming, pristine folders, or heroic memory. Pixel Dust keeps a private, searchable timeline so your past work is always one shortcut away.

Pixel Dust runs in the background and captures moments from your screen at a configurable cadence. It extracts OCR text and semantic vectors for retrieval, then lets you instantly search or ask questions.

It is built for people who live in tabs, docs, code, chat, and meetings. Instead of context-switching to reconstruct what happened, you jump straight to the source moment.

How it works

Capture -> OCR -> Retrieval -> Ask

Four steps turn your day into something queryable, without forcing you to manually save or tag everything.

1

Capture

Pixel Dust records lightweight timeline moments from your screen in the background, with pause available from the menu bar.

2

OCR

Readable text is extracted from each moment so snippets from docs, chats, slides, and browser tabs become searchable.

3

Retrieval

Keyword and semantic indexing map your timeline for instant recall, including fuzzy queries when wording is imperfect.

4

Ask

Ask natural-language questions against your own history and jump to the source moment instead of hunting through apps.

Why it is different

Private. Fast. Built for real recall.

Pixel Dust is opinionated about speed and ownership. It is not another cloud transcript dump.

Local-first architecture

Screenshots, OCR text, and embeddings stay on your Mac by default. No hidden cloud sync.

Privacy controls that matter

App exclusions, window redaction, keyword scrambling, retention policy, and one-click pause/delete.

Speed over ceremony

Keyboard-first recall is measured in seconds, so context-switches are shorter and less mentally expensive.

Source-grounded answers

Ask mode cites your own timeline moments, helping avoid made-up answers and stale memory guesses.

Feature highlights

Everything you need to remember work in motion.

Designed for people who forget where they saw something, not people with perfect filing systems.

Trust and security

Built with privacy posture first, growth hacks second.

Your timeline can be deeply sensitive. Pixel Dust defaults to local ownership and explicit control.

Data residency: your Mac

Captured moments and indexes are stored locally and encrypted at rest. Nothing is sold or used for ad targeting.

Explicit cloud opt-in

Any remote model integration is opt-in and visible. If you never enable it, your timeline remains local.

Operational controls

Pause capture, exclude apps, redact windows, and purge history without opening a support ticket.

FAQ

Common questions before you install.

What data does Pixel Dust store?

By default it stores timeline thumbnails, OCR text, and retrieval embeddings on your Mac. Optional full video mode is off until you enable it.

Can I disable capture whenever I want?

Yes. Use the menu bar control for immediate pause, plus exclusion and deletion controls in settings.

Does Pixel Dust work offline?

Core capture, indexing, and search are local-first and work offline. Cloud AI behavior depends on whether you enable an external provider.
