Head-to-head
Totally Lean vs Miro
Same Lean Canvas framework, two very different products. Totally Lean runs entirely in your browser with no account, no server, and free AI features that edit what you wrote. Miro is a general-purpose online whiteboard with a large template library including lean canvas.

When to pick which
Pick Totally Lean if…
- You want to sketch a business model tonight, without a signup flow between you and the canvas.
- Your early hypotheses shouldn't sit on a third party's server.
- You want AI help on your canvas — but the AI should edit what you wrote, not write for you.
- You share canvases with people who shouldn't have to install or sign up for anything.
- You want the Sankey flow, threads, and weighted validation without paying.
Pick Miro if…
- You already use Miro for other work and don't want another tool.
- You run live whiteboard workshops where multiple people sketch together.
- You need a wide range of templates, not only Lean Canvas.
- Your team pays for Miro anyway and you want to use what you already have.
Methodology & sources
- What was compared
- Feature availability on the public product, pricing on the public pricing page, and data-handling claims published by the vendor. Features marked as local ai rewrites a single field you wroteor similar are treated as “yes” only when the vendor documents them publicly; unverified items show as “not documented.”
- What was tested
- Totally Lean: the author uses and maintains it. Miro: observed from the public marketing site and documentation. We did not test paid tiers or private team features.
