Welcome to StackSave — Save Any Note, Find It Later
Comment @stacksave on anything worth keeping. Then search it all in one place.
Substack’s save button only works on posts. But the best stuff is usually somewhere else — a sharp Note, a reply buried in a comment thread, a one-liner someone dropped that you swore you’d remember. Then you scroll, and it’s gone.
StackSave fixes that. It’s a searchable archive for the things Substack won’t let you save.
How it works (it’s one step)
See something worth keeping — a Note, a post, a comment, a whole thread.
Reply with
@stacksave— same as tagging anyone on Substack.Find it later in your archive — searchable by text, author, and date.
That’s it. No app to install, no button to hunt for. If you can mention someone, you can save anything.
One thing to watch: it only counts when @stacksave is a real tagged mention.
✅ A blue @stacksave (chosen from the dropdown) saves.
❌ Plain grey @stacksave text doesn’t — Substack only notifies us about real mentions.
Where your saves live
Every time you tag @stacksave, that item lands in your private archive at stacksave.live — quietly, no reply cluttering the thread.
To open your archive: subscribe to this publication, and we’ll email you a one-tap sign-in link. Anything you saved before signing in will already be waiting there.
Why bother?
Two reasons:
For you — your archive becomes a searchable swipe file of the best writing on Substack: ideas to build on, lines worth revisiting, proof for your own posts. The stuff you’d normally lose to the scroll, kept and findable.
For the writer — saving someone is a quiet vote of confidence. Every @stacksave is public, so when you save a Note, you’re signaling to that creator (and everyone reading the thread) that their work was worth keeping. It’s a small, genuine way to lift other writers up — the kind of goodwill that tends to come back around.
We’re building toward more here — recognition for creators whose work gets saved often, and ways to discover the most-saved writing on Substack. Early days, but that’s the direction.
We bring it back to you
Saving is only half of it. The real problem is forgetting you saved it — most archives quietly turn into a graveyard you never reopen.
So once a week, StackSave emails you a short digest that resurfaces what you’ve kept. No effort, no remembering to check — the good stuff comes back to you, and your archive stays a living swipe file instead of a junk drawer.
What StackSave catches that the native Substack save doesn’t
✅ Notes (native save: posts only)
✅ Comment threads & replies
✅ Full-text search across everything you’ve saved
✅ Save by mention — no copy-pasting links
✅ Weekly resurface digest — your saves come back to you
A note on early days
StackSave is brand new and we’re in beta testing . I’d genuinely love your feedback — reply to this post or comment on a Note and tell me what’s working and what isn’t.

Very clever, and the marketing is built-in. This is much better than my "Save to Vault" button I created as a Chrome extension. I'll try it out.
Of course this is the week Substack introduces saving notes….
