Save Social Media Posts
Before They're Gone

PostKeep saves the content of any social media post — text, images, tags, links, etc., all locally on your device. Your copy survives even if the original is deleted. View, search, and organize your saved posts anytime, and send copies to anyone — even someone who isn't on the platform it came from. No Cloud, No tracking.

The problem

Posts disappear. All the time.

A bookmark is just a pointer. Algorithms bury Posts to keep you scrolling. Posts get deleted, accounts get suspended, platforms shut down. When the destination is gone or you can't find it, so is everything you wanted to keep.

The problem

Posts are scattered and unsearchable.

YouTube favourites, Instagram saves, and Threads bookmarks etc each live in their own silo. There's no way to search across them, tag them, or get them out.

How it works

One tap by you. Permanent.

Save from X, Threads, Reddit, Instagram, YouTube, LinkedIn, TikTok, and more — with one tap from any app. No PostKeep account / login.

1
Tap the share button
From any social media app, tap the share icon — the same one you'd use to send a message. PostKeep appears as a destination in your share sheet.

Sharing

Send it to anyone.

A link assumes the person you're sending it to is on that platform. Send them the post itself instead — as a clean card or a PDF that opens for anyone, with no account, no app, and no login wall.

Share a post
PostKeep recommends the right format for each post — a card for short posts, a PDF for long or image-heavy ones. Only the post you choose leaves your vault.
Share a collection PRO
Filter by tag, wording, platform or date, then send the whole set as one document — posts from every platform side by side. No platform can show you that, because each one only holds its own.
Features & Privacy

Built to be used. Built to be trusted.

Everything you need to capture and keep posts — nothing that gets in your way.

One-tap save
Share any post to PostKeep from the iOS share sheet. Saved in a few seconds, all essential content captured.
Share to anyone
Send any saved post as a card or a PDF. Readable by someone with no account on that platform, and no PostKeep either.
Search everything
Find any post by keyword, tag, or platform — including the text inside images, read on-device.
Works offline
Your vault is fully accessible without an internet connection. Browse, search, and read everything you've saved, anywhere.
No account needed
No email, no password, no profile. Nothing to sign up for and nothing to lose if PostKeep disappears.
Optional cloud backup
Enable Cloud backup to keep your vault safe across devices. Off by default — you choose if and when to turn it on.
AES-256 on-device encryption
Your vault is encrypted on your device. Only you hold the key — PostKeep never sees it.
Encrypted cloud backup
If you enable Cloud backup, your vault is encrypted before it leaves your device. The cloud provider sees only encrypted bytes.
