Visio alternative
A Visio alternative that works in any browser.
Visio is the classic for business diagrams, and a lot to buy and install for a flowchart. Builderii draws the diagrams most teams need in any browser, has an AI that does the first draft and the changes, and lets the whole team edit together.
Works in your browser · No card · Free to start
In short
Builderii is a Visio alternative, free to start, that runs in any browser, on a Mac or a PC, with nothing to install. Its AI draws flowcharts, sequence diagrams, ER diagrams, sitemaps and roadmaps from a sentence and changes them in place, a spreadsheet becomes an org chart in one click, and your team edits live with cursors and comments. Visio is the better pick for its huge stencil libraries, BPMN and network diagrams, and data-linked diagrams in the Microsoft world.
