1. Create your account
Create an account on tuckthis.app. Tuck confirms your email with a sign-in link. If early access is enabled, signup may also ask for an invite or referral code. A friend’s referral code counts as an invite, and opening their referral link fills it in for you. After your first sign-in, you can add a passkey so future sign-ins do not require an email link.2. Create your vault
On your first device, Tuck asks you to create a vault passphrase. This is different from signing in to your Tuck account. Choose something strong that you can remember. Tuck uses it to unlock the encryption key for your vault. If Tuck says This account already has a vault. Reload to unlock it., your vault was already created, perhaps in another tab or on another device. Reload the page and unlock it with that vault’s passphrase instead of making a new one. A new vault includes four welcome thoughts: a short tour, getting-started docs, your referral details, and Recovery Kit guidance. The docs thought demonstrates a todo suggestion, and the referral thought includes an open todo. You can edit or delete these thoughts as you settle in.3. Save your Recovery Kit
Tuck creates a Recovery Kit when your vault is created. Store it somewhere you can reach if you forget your vault passphrase.4. Tuck your first thought
Focus the capture box with⌘K on Mac or Ctrl+K on Windows and Linux. Type something and press Enter.
That is enough to start.
