Frequently asked questions
Is this free, and do I need to sign up?
Free, no sign-up. Inputs and results stay in your browser. Analytics record only a tool identifier and action, never your input.
Which frameworks can I edit?
Lean canvas has nine blocks, business model canvas has nine, and value proposition canvas has six blocks split between the customer profile and value map.
Does this generate a validated business?
No. It is a manual editor, not an AI business validator. The canvas records hypotheses, which you must test with customers. Blank blocks are marked To complete in exports.
Are drafts saved between visits?
No. Each framework keeps its own draft only in memory while this page remains open. Export before closing or reloading; no server storage or automatic local persistence is used.
Does PNG export truncate my notes?
The image height expands to fit wrapped text, including line breaks and long words. Each field is limited to 2,000 characters; exceptionally tall exports are rejected with a clear message. Markdown preserves all entered notes.
Are these official branded templates?
This is an independent SaaS editor. Lean Canvas is attributed to Ash Maurya; Business Model Canvas and Value Proposition Canvas to Strategyzer. The layout is our own worksheet, with no implied partnership.
Is a Genesis example prefilled?
No. Start with your own hypotheses. The next step links the public Genesis bank for researched directions; no unpublished idea data is loaded into this editor.
