Invite as Many People to your Board as you Need
Drag and drop people to cards to divvy up tasks. Everyone sees the same board and the whole picture all at once.

Start a Discussion with Comments and Attachments
Add a quick note or a detailed, Markdown-enabled diatribe. Mention a member in a comment to make sure they get notified. Add files by uploading them from your computer, Google Drive, Dropbox, Box, and OneDrive. Liven it up with emojis, too.

Notification System
You’ll get notifications wherever you are: inside the app, via email, desktop notifications via the browser, or via mobile push notifications. Notifications stay in sync across all your devices.

Checklists and Due Dates
You won’t miss important tasks, upcoming dates, or items. And with the Calendar Power-Up, everything is in a nice calendar view inside Trello. Or use the iCal feed in your own calendar app.

Use Organizations to Keep Everyone Connected
Organizations are groups of people and boards, like your company, your family, or your roommates. You can make as many organizations as you want with your free account.

Trello Works Wherever you are
We have apps for iPhone, iPad, Android phones, tablets, and watches, Kindle Fire Tablets, and Windows 8. Trello also works on the web at any screen size.

You’ll Find Everything with Search, Filtering, and Labels
Search is incredible fast and powerful, with sophisticated operators that help you narrow your search. Labels help you finely categorize your cards so you can find and filter them later. You’ll never lose a card.

Power-Ups
We’re dedicated to keeping the core of Trello dead simple. We’ll never overload you with features you won’t use. If you’re looking for a bit more, we’ve got Power-Ups, like Calendar, Voting, and Card Aging, that you can turn on. It’s a way to give your boards a little more umph without adding a billion buttons and making Trello hard to use.

Create Cards and Comment via Email
Every board has a special email address you can use to create cards. Trello uploads the attachments you send along, too. Also, when you get notifications via email, you can reply via email without opening Trello. Pretty handy.

Private and Secure
You have full control over who sees your boards. All data is sent over a secure, SSL/HTTPS connection, the same encryption technology used by banks. We keep encrypted, off-site backups of your data in case of disasters.
