Peekaboo is a native macOS task manager built by Emanuele Di Pietro that hides in a screen corner and reveals itself when you rest the cursor there. On Mac, you choose a screen corner and pause your cursor there to reveal your tasks, and moving away tucks Peekaboo quietly back into the corner. Work is organized across To Do, In Progress, and Done, with a Backlog for capturing ideas until you are ready to start , plus None, Low, Medium, or High priority per item. A purchase includes both the Mac app and its iPhone companion, which sync automatically over the same iCloud account with no separate login .
The launch is filed under AI Agents because of an optional integration path for local assistants. On Mac, Agent Access lets compatible local AI assistants connect to Peekaboo through the Model Context Protocol (MCP), where they can read, create, update, complete, and delete tasks without controlling the app's interface. Agent Access is disabled by default, runs only on your Mac, and requires a private access token , and Peekaboo stores tasks locally using SwiftData and synchronizes them through your private iCloud database , so the surface area exposed to any agent stays on device.
This release matters because it lands as more developers wire MCP-capable tools (Claude, Codex, and similar) into their daily workflow and want a lightweight, always-available place for those agents to drop and retrieve tasks. Di Pietro is shipping Peekaboo as a tiny, open source, native Mac utility rather than another Electron productivity suite, aimed at operators and builders who want a task list that stays out of the way until a cursor flick or an agent call brings it back.

Category says AI Agents but I see zero agents here, just a hot corner and a to-do list. Not mad about it, just noting the App Store SEO hustle.

The corner-hover interaction is the entire pitch and it's a good one. Screen-recording that in the launch tweet instead of a static shot would've printed way more clicks.

Opensource + native + tiny is a rare trifecta on Mac these days. Please don't add a Slack integration in v2.

Where does the task data live, iCloud or local sqlite? Asking because I'd like to actually trust this thing before I dump my life into it.

Tweet cuts off mid-bullet with a t.co link, brutal. Whatever came after 'Set' better be worth the cliffhanger.

Counterpoint: the truncated tweet made me click through to see what 'Set' was. Chaos as a funnel, unintentional but effective.

Kanban in a screen corner is such a 2019 idea I'm delighted someone finally shipped it. Whatever happened to Trello desktop widgets, huh.

Reminds me of a portfolio thing we passed on because 'too small to be a company,' now I use three of those every day. Rooting for tiny native apps.

Launch tweet has no screenshot in the first frame, first-scroll conversion is going to suffer. Pin a 6-second silent loop as the top reply, thank me later.
