Features
A memory for the things you save
Saving is easy. Finding it again three weeks later is the hard part — that is the part Keepstack is built for.
Save from anywhere
Share from Safari, social apps or Photos straight into your stack. Saved pages keep their title, preview image and full text.
On-device AI
Reads the text inside screenshots, writes key-point summaries and sorts saves into smart categories — all on your iPhone.
Search by meaning
“That pasta sauce” finds the recipe even when those words aren’t in it. Your saves show up in iPhone Spotlight too.
Collections & categories
Group saves into collections — Recipes, Travel, Finance, Tech or your own. One item can live in several at once.
Six kinds of save
Web links, notes, photos & screenshots, videos, voice memos and PDFs — one stack, not six scattered apps.
Private by design
No account, no sign-up, no ads, no tracking across apps. Saves stay on your device — or sync privately through your own iCloud.
How it works
Three taps, then forget about it
Share it in
Hit Share in any app and pick Keepstack — or capture a note, photo, voice memo or PDF directly inside the app.
It reads itself
Keepstack pulls the page text, runs OCR over screenshots, writes a summary and suggests tags and a category. On device.
Find it later
Search by what it meant, not the exact words. Browse by collection, kind or date — or set a reminder to come back to it.
Your stack is nobody else’s business
No account. No advertising SDKs. No server of ours ever receives what you save. The AI that reads your screenshots runs on your iPhone, using Apple’s own frameworks — nothing is sent to an AI service. The app sends anonymous usage statistics so we know what to improve; they contain nothing you saved, and you can switch them off in Settings.

Questions
Good to know
Do I need an account?
No. There is no sign-up and no login anywhere in Keepstack. Open the app and start saving.
Where is my data kept?
On your iPhone. If you switch on iCloud Sync, your saves also sync through your own private iCloud account so they appear on your other devices — that stays between you and Apple. None of your saves ever reach a server of ours — the only thing we receive is anonymous usage statistics, which you can turn off in Settings.
Does the AI send my saves anywhere?
No. Text recognition, voice-memo transcription, summaries, tagging and semantic search all run on your device using Apple’s Vision, Natural Language, Speech and Apple Intelligence frameworks. Voice memos are transcribed in the languages Apple can transcribe on the device.
Do you collect any usage data?
Anonymous statistics only — device and app version, which screens are opened, and crash diagnostics — tied to a random installation ID, never to you, and never including anything you saved. Switch it off in Settings → Privacy. Details.
What happens to my saves if I stop paying for Pro?
Nothing is deleted or locked. Everything you saved stays; only the Pro features switch off until you resubscribe.
Which device do I need?
Keepstack runs on iPhone and iPad with iOS 17 and later.
