How can
we help?

An iPhone with iOS 27 or later. Sanctum also runs on iPad, but it's designed for iPhone.

No. Open the app and start saving. There's no sign-up and no profile.

Nothing. Sanctum is free, with no in-app purchases and no ads.

1. In Sanctum, tap +, then Ask any AI, then Copy the prompt.
2. Paste it into ChatGPT, Claude, Gemini or any AI, with your quotes under it: a list, your notes, screenshots' text, or just a topic you need lines for.
3. Copy the AI's answer, come back to Sanctum and paste it. Every line shows for review, word for word, with its topic.
4. Untick any you don't want, then tap Add.

Sanctum doesn't talk to the AI itself; you carry the words across, so nothing leaves your phone unless you paste it somewhere.

Yes. Tap +, then Paste notes. Numbered lists, bullets, one per line, "quote" — Author: Sanctum splits it into lines and files each under a topic. Tap Join between two pieces if it split wrong, or long-press a piece to split it.

No. Sanctum never asks for Photos. Paste the words instead, or hand the text to any AI with Sanctum's prompt.

1. Select the text in any app, such as Safari, Books or Notes.
2. Tap Share.
3. Choose Save to Sanctum.

1. Open the Share sheet and scroll the row of actions to the end.
2. Tap Edit Actions (or More).
3. Find Save to Sanctum, turn it on, and drag it near the top so it's easy to reach.

If it's still missing, open Sanctum once after installing or updating, then try again.

Yes. Add a line in the app and type it in. Notes to yourself are some of the best lines.

1. Open All lines, touch and hold a collection, and choose Share collection.
2. Tap Send it and pick AirDrop, Messages, Mail or Files.
3. On their iPhone, they tap the .sanctum file. It opens in Sanctum, shows them what's in it, and one tap adds it as a collection of theirs. They need Sanctum installed.

Only the lines go: no saves, dates or check-ins. Lines they already have are left as they are.

No. Every line is kept exactly as written.

Sorting happens automatically on your phone, so it won't always be perfect. You can move a line to a different topic or collection in the app.

1. Touch and hold an empty area of your Home Screen until the apps jiggle.
2. Tap Edit, then Add Widget.
3. Search for Sanctum, choose a size, and tap Add Widget.

1. Touch and hold your Lock Screen, then tap Customize.
2. Choose the Lock Screen, then tap the area below the clock.
3. Pick Sanctum from the list.

Remember that Lock Screen widgets can be seen without unlocking your phone.

1. Swipe down from the top-right corner to open Control Center.
2. Touch and hold an empty area, then tap Add a Control.
3. Search for Sanctum and choose a control.

iOS decides exactly when widgets refresh, so a new line can take a little while to appear. If it seems stuck:

• Open Sanctum once, then return to your Home Screen.
• Check that Low Power Mode is off, since it can delay widget updates.
• Remove the widget and add it again.

• Go to Settings > Notifications > Sanctum and make sure Allow Notifications is on.
• Check whether a Focus mode is silencing Sanctum, and add it as an allowed app if you'd like.
• If you use Scheduled Summary, your reminder may be grouped into the summary instead of arriving on its own.

Yes, you can choose the time in Sanctum's settings.

Sanctum sends one reminder a day on purpose. Your widgets and Control Center are there whenever you want more.

No. Miss a day or a month and nothing is lost.

On your iPhone. They never leave your phone. Read more in our privacy policy.

Deleting Sanctum deletes all of your lines from your iPhone. We don't keep a copy, so we can't restore them.

Either set up your new iPhone from a backup of your old one (iCloud Backup, Quick Start or a computer) and Sanctum's data comes across with the rest of your apps, or in Sanctum open your profile, tap Back up & share my lines, save the file to Files or iCloud Drive, and on the new iPhone tap Restore in the same place and pick it.

No. Your lines stay on the device where you saved them.
