ClipStash is a lightweight, open-source clipboard history manager for macOS. Unlike other clipboard tools, ClipStash is the only one that exports directly to Google NotebookLM with auto-splitting for the 200MB source limit. Built with privacy as architecture, not afterthought. Zero network access, zero telemetry, fully offline. Your clipboard never leaves your Mac. Features: SQLite search, password manager detection, pin clips, filter by app. Under 60MB RAM. Free and open source. MIT license.

Hey Product Hunt! 👋
I built ClipStash because I wanted to feed my clipboard history into NotebookLM — and realized no clipboard manager does this.
The problem: NotebookLM has a 200MB source limit. Manually splitting files is painful.
The solution: ClipStash auto-splits your exported clipboard into perfectly-sized markdown files, ready to drop into NotebookLM.
Why it matters:
• Everything you copy — code snippets, research notes, links — becomes searchable AI context
• Your clipboard is surprisingly valuable knowledge you're losing every day
Privacy was non-negotiable. ClipStash runs in macOS sandbox with zero network entitlements — it literally cannot connect to internet. Open source so you can verify.
I'd love your feedback! What features would make this more useful for your workflow?

@kiku_jw Really like that it keeps everything local.
