Miro alternative
Less whiteboard sprawl. More product.
Miro is a huge canvas for whole companies. Builderii is focused on what product teams make: flows, wireframes and prototypes, drawn by AI and kept tidy by real layout engines, so diagrams stay neat while you change them.

Why teams pick Builderii
Focused on the work you ship.
AI with layout engines
The AI decides what to draw; Builderii lays it out. Flowcharts, mind maps and roadmaps come out tidy, and stay tidy when they change.
Screens and prototypes
Linked app screens from a prompt, low- or high-fidelity, then click through them in the player.
Test with real people
A test link records taps and paths. See heatmaps and where people stopped, right on the board.
Keyboard-first
Single-key tools, ⌥+Arrow quick-add, one-click auto-layout, and ⌘K for every command.
Teams and projects
Team boards everyone can edit, and shared projects with Can edit, Can comment and Can view.
Claude and ChatGPT
Draw and change boards from your AI assistant through Builderii’s MCP server.

Questions
Good questions.
Is Builderii a free Miro alternative?
Yes. Builderii is free while it’s new, with every feature on and 500 AI jobs a month per person. Viewers and commenters will always be free, and paid plans will publish their AI allowances.
Can I run workshops in Builderii?
Yes: sticky notes, stamps, voting with hidden cursors, a timer, templates for retros, SWOT and journey maps, and AI that groups notes by theme and summarises the board.
Can I import from Miro?
There’s no Miro import. Import Excalidraw and draw.io files, paste Mermaid code for editable shapes, paste spreadsheet cells for a table (or an org chart), and paste SQL or Prisma for a database diagram. A screenshot of an existing screen or diagram becomes an editable wireframe or flowchart through the AI bar’s image button.
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.
