Common questions
Why do I sign in?
Your account is what lets your boards sync to the web, lets you share a board with other people, and lets ChatGPT or Claude connect to Sidepaper if you choose. You sign in once, the first time you open the app; after that, writing works offline. Sign in with Apple or Google.
How do I see my boards on the web?
In the app, open your account and turn on sync. Then sign in with the same account at sidepaper-web.vercel.app. Photos and recordings stay on your iPhone.
How do I share a board?
Open the board, tap ⋯ and Share, type the email the other person signs in with, choose whether they can edit, and send them the invite link. The link works once, for that email, for 7 days.
How do I delete my account?
In the app, open your account and tap Delete account. It deletes your account and everything synced to it; boards kept only on your iPhone stay there until you delete the app. You can also email us and we'll do it for you.
Something went wrong with a reply from ChatGPT or Claude.
Replies always arrive as suggestions; nothing on your board changes until you keep them, and one step undoes them all. If a reply doesn't open, paste it again from the assistant, or email us the board's name and what you saw.
