The most natural online whiteboard
IDroo does everything you would expect from an online whiteboard. Instant real time collaboration in your browser without the hassle.
Number one choice for online teachers
IDroo connects thousands of students with teachers for real-time collaboration all over the world.
Start working in seconds
Just share the URL of your board with others and you can instantly collaborate. Log in with social accounts available (Facebook, Google, Windows Live).
Each stroke you make and letter you type is transmitted in real time to all the participants worldwide.
All the tools you expect and even more
Freehand, Line, Rectangle/Square, Ellipse/circle, Text, Formula/Equation, Images and Documents, and an Eraser, of course.
Nice and smooth lines
Draw and sketch your ideas with Freehand tool. Pen tablets or touch screens make drawing easier but are not required. With IDroo, your lines are smooth even with a janky mouse.
You can use our simple yet professional equation editor to type math and physics formulas. Use the toolbar, or TeX-like commands such as \sum, \sqrt, \alpha, \N, etc followed by a space.
Images and documents
Upload images, PDF, Word or other documents by simply pasting or dragging them to the board. You can easily reuse files you have uploaded on other boards. Supported formats include JPG, PNG, GIF, PDF, DOCx, XLSx, PPTx, PAGES, RTF, and many more.
Lock to background
Objects can be locked to background to protect them from deleting or moving around by accident. For example, lock a document page in place to work on it.
Style as you wish
Different fonts and stoke widths, millions of colors to choose from, even all the partially transparent ones.
Everything on the board can be freely copied, changed, moved, scaled, rotated or deleted.
The digital paper we use in IDroo is infinite in all directions and you are working at the center of it. The pens have infinite ink too, to compensate.
Your boards are automatically saved on our server so you can access them later, anywhere and your work won't get lost. You can also access the boards you have been on but don't own. For example, students have access to the teachers boards they have worked on.
All devices and screen sizes
IDroo works on desktop, tablets and everything in between.
No download required
Runs in your web browser, no need to install anything.
All your favorite shortcuts from other programs work in IDroo. Ctrl+C, +V, +X, +Z, +Y. On a touch device hold you finger on the board and a menu appears.
Private and protected when you need it
Board owner can change the default permissions for new joining users. By default all users have permissions to Edit, but it can be changed to View or None. You can also change the permissions for users already on the board, effective immediately.
There is an integrated chat that is saved with the whiteboard so no message gets lost.
