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.

Spine is a YC S23-backed AI agent swarm platform that launched a major integrations update today — agents can now pull data from and push finished work to 300+ apps including Notion, Google Docs, Sheets, BigQuery, Snowflake, Salesforce, and more. The platform handles autonomous multi-step research, analysis, and document creation, delivering results directly to wherever your team lives. The integrations update transforms Spine from a standalone agent into a genuine cross-app autonomous worker. A single prompt like "research our top 10 competitors and put a 50-page strategy doc in Notion" now executes end-to-end without human hand-holding — agents coordinate, sources get cited, and the output lands in the right destination. Previous versions required manual copy-paste between Spine and your actual work tools. Spine uses a swarm architecture where specialized sub-agents handle different parts of large tasks in parallel before merging their outputs. The update also adds a new Task Monitor that shows which agents are working on what in real time, giving users visibility into the swarm's progress rather than a black-box wait.
Reviewer scorecard
“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.”
“The 300-integration update is the unlock that turns Spine from an interesting demo into a workflow replacement. The combination of swarm parallelism and direct delivery to work tools is a genuine productivity multiplier. Ship it for research-heavy tasks immediately.”
“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.”
“50-page AI-generated strategy docs sound impressive until you have to review one. Swarm agents that autonomously write to your Notion, Salesforce, and Snowflake are one bad prompt away from expensive messes. The oversight model needs work before this goes near production data.”
“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.”
“Agents that write directly into your system of record — not just suggest edits but actually commit the work — is the next frontier of automation. Spine is early on this, but the integration depth here is the right bet. The companies that embed agents into their data flows now will have structural advantages.”
“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.”
“Research-to-Notion in one prompt is something I've been manually doing in 3 hours. If the output quality holds up for real projects and not just demos, this is a permanent fixture in content workflows.”
