Core is an open-source "AI operating system" built around a single premise: AI should remove operational friction, not just build-time friction. While most AI tools require you to brief them every session and manually synthesize their outputs, Core ships with Alfred — a persistent, named butler agent that executes scheduled tasks autonomously and surfaces results where you already work. The philosophical distinction is between directive AI (you tell it what to do each time) and ambient AI (it runs your backlog while you focus on other things). Alfred maintains context across sessions, executes routine operations on schedule, and doesn't wait to be invoked. Think scheduled research summaries, automated triage, or recurring data pulls — tasks that currently require either expensive automation platforms or manual check-ins. The project is self-hostable via GitHub and is currently in waitlist mode for the hosted version. It's early-stage, but the architecture — a persistent agent with long-running task support and integrations into existing workflows rather than a separate chat interface — points toward a category of tooling that's been largely missing. Most AI assistants are reactive; Core is explicitly designed to be proactive.

PromptPaste is a native Apple app that lets you save, organize, and instantly paste AI prompts from a Mac menu bar overlay or iOS share sheet. Hit ⌘⇧P anywhere on Mac and your entire prompt library is accessible without switching apps or hunting through notes. The app supports dynamic templates using {{variable}} placeholders so prompts can be customized at paste-time, folder-based organization, iCloud sync across all Apple devices, and link-based sharing of prompt collections. Crucially, everything is stored locally — no account required, no cloud sync of your actual prompts outside of iCloud. Built by indie developer Ivan Terehin, PromptPaste fills a genuine gap: most people accumulate dozens of AI prompts scattered across notes, docs, and chat history. Works with every major AI platform — ChatGPT, Claude, Gemini, Grok, Midjourney, GitHub Copilot, and more.
Reviewer scorecard
“The persistent agent with long-running tasks is the right product bet. Most agent frameworks make you rebuild context every session. If Alfred actually maintains state and runs scheduled work reliably, that's solving a real problem. The self-host option with GitHub access is enough to evaluate the architecture.”
“The ⌘⇧P hotkey that drops your prompt library anywhere is the feature I didn't know I needed. I have system prompts, code review templates, and git commit formats that I paste constantly — having them one keystroke away instead of buried in Notion is a real productivity win.”
“Persistent AI agents that run autonomously have a well-documented failure mode: they quietly drift off-task, make irreversible decisions, or rack up API costs with no human in the loop. 'Works while you sleep' sounds great until Alfred posts the wrong thing or deletes the wrong file. The waitlist and vague integration promises suggest this is vapor-forward.”
“This is a well-executed clipboard manager with an AI marketing angle, not really AI itself. Raycast and Alfred already do this with snippet libraries, and most power users are already in those ecosystems. The Apple-only constraint also limits its audience significantly.”
“The ambient computing model — where AI handles operational work continuously rather than responding to prompts — is where the category is heading. Core's framing of 'AI OS' is early, but the architectural intuition is correct. The teams that figure out reliable long-running agent infrastructure in 2026 will be building something foundational.”
“Personal prompt libraries are the new dotfiles — the accumulated knowledge of how to get AI tools to work for your specific workflows. Apps like PromptPaste are the beginning of a whole category of 'AI configuration layer' tools that will become essential infrastructure.”
“For creative workflows, I want AI that responds to what I'm making, not one that's silently operating in the background. The waitlist + vague integrations make it hard to evaluate for content use cases. I'd want to see specific creator-focused workflows before recommending this over established automation tools.”
“For creators who use AI daily across writing, image generation, and video tools, having a single organized library across Mac and iPhone with variable templating is exactly the kind of workflow glue that saves an hour a week.”
