Online whiteboard
A free online whiteboard that does the tidying for you.
An infinite, dotted canvas for the whole team, with everything a whiteboard needs and an AI that does the tedious part: grouping the sticky notes, writing the summary, and turning the result into a flowchart or a set of screens.

In short
Builderii is a free online whiteboard for teams. Everyone sees live cursors and edits, can follow or spotlight, chat at their cursor and react, and leave comments with @mentions. Sticky notes, stamps, dot voting, a timer, a marker and a laser pointer cover workshops, and AI groups notes by theme, summarises the board and draws flowcharts, mind maps and app screens.

Questions
Good questions.
Is this online whiteboard free?
Yes. Builderii is free while it’s new, with every feature on and 200 AI jobs a month per person. Viewers and commenters will always be free, and paid plans will publish their AI allowances.
Do guests need an account?
Not to watch. Anyone with a board’s share link can view it without an account, play its prototype and see edits live, as a named guest with their own cursor. To edit or comment, people sign in and get access by invite, team or link.
Can my team work on a board together?
Yes. Everyone on a board sees live cursors and edits as they happen, can follow someone’s view, chat at their cursor and leave comments with @mentions that send a notification and an email. Invite people as editors, commenters or viewers, or share a link.
Does it work on a phone?
Boards open on phones for looking: pan, zoom, read comments and play prototypes. Making and editing boards is for a computer or a tablet.
