Why we made it
Working on more than one laptop means logging in to WhatsApp Web or Gmail just to move one note, photo or PDF file. And remembering to log out. Here you just type your username and PIN. Everything is already there.
See It Live
1. Ravi logs in on his office laptop. Just a username and a 6-digit PIN.
Step by step: log in with a username and PIN, create a board, share its QR code, a friend scans it on their phone and joins then notes, files and drawings sync live between both devices.
Unlimited Devices
Log in on as many phones, laptops and PCs as you like. Notes, drawings and files (PDFs, photos, sheets) are pinned once and show up on every screen, live, with who added them and when.
Animation: people on an office PC, a home laptop, a tablet and phones add ideas to one shared board and every idea appears on every screen within seconds. Any number of devices can be logged in.

How It Works
Takes 10 seconds. That's your account on every device.
One for home, one for office, one for the family. As many as you like.
Share a QR or 6-digit code or add people by username. Everyone sees it live.
Private by design
Just a username and a 6-digit PIN for you. Behind it, the protections a serious app should have.
Only a salted, peppered hash. Not even we can read your PIN.
Forgot your PIN? Your recovery code resets it and logs every other device out.
Wrong PINs are limited per account, device and network. Your own devices stay trusted.
Every logged-in device is listed. Log one out or all others, in a tap.
No public links. Owners can remove, block and report anyone.
No phone, email or contacts. Files and text delete themselves after 7 days.
Always served over HTTPS with strict security headers. No app can promise to be unhackable. We keep the doors few and the locks strong.
Good To Know

Log in with the same username on every device. Your boards, sticky notes, drawings and files show up everywhere and update live within a couple of seconds.
Open the board, tap Share and show them the QR or 6-digit code. Or add them by their username. Only people you add can see the board. There are no public links.
Yes. Drag the corner of any note to resize it, change its colour, make the text bigger or smaller, copy it or duplicate it. Every note shows who wrote it and when.
Any file (photos, PDFs, videos, documents, zips) plus plain text snippets. Filter by type (PNG, JPG, PDF…), date or person. Files and text delete automatically after 7 days. Sticky notes and drawings stay.
Yes, with the recovery code you got when you made your account: tap "Forgot PIN?" on the login card, enter your username, the code and a new PIN. Every other device is logged out and you get a fresh code. We never ask for a phone or email so if you lose your username or both your PIN and your recovery code, the account can't be recovered and you'll need a new one.
Open Security & devices and tap Log out everywhere. Every phone and computer is logged out at once. A device you have not used for 90 days is logged out by itself.
Your PIN is never stored. Only a salted, peppered hash. Repeated wrong PINs are blocked per account, device and network. You can see every logged-in device and log any of them out from Security & devices. You stay logged in until you log out. Boards are only visible to people you add.
Yes, Hi Boards is free to use. It works in any browser and there's an Android app too.
Open Security & devices, scroll to Delete my account and enter your PIN. Your account, your memberships and any board only you were on are deleted straight away.
Free forever for home, family and small teams.
