List the top 1 to 3 problems, one per line. Add the existing alternatives people use today.
Who has the problem? Name the early adopters you would call first.
One clear sentence on why you are different and worth a click. Optional: a high-level concept such as X for Y.
One simple feature per problem, one per line. Not a roadmap.
How you will reach those customers, free and paid.
What customers pay for and how. Add a price if you have tested one, or mark it as an assumption.
What it takes to win customers, deliver the product and run the team.
The few numbers that tell you the business is working, one per line.
Something that cannot be copied or bought easily. Leave it blank if you have none yet; that is an honest answer.
    How it works

    What this lean canvas template does for you

    Nine boxes on one page

    The layout follows the lean canvas Ash Maurya adapted from the Business Model Canvas: Problem, Customer Segments, Unique Value Proposition, Solution, Channels, Revenue Streams, Cost Structure, Key Metrics and Unfair Advantage. On a phone the boxes stack in a suggested fill order.

    Checks on your wording

    As you type, the tool looks for common gaps: more than three problems, fewer solutions than problems, a long value proposition, a revenue box with no price, and an advantage anyone could copy. These are editorial rules of thumb, not a score and not market data.

    Copy or download

    The canvas is rebuilt as Markdown text under the boxes after every keystroke. Copy it into a document or download it as a file. Everything runs in your browser, so nothing is saved once you close the tab.

    Before you start

    How to fill in a lean canvas without fooling yourself

    1. 1

      Start with the problem, not the product

      Write the top one to three problems your customer has, and the alternatives they use today. If nobody uses any alternative, ask yourself whether the problem is real.

    2. 2

      Name who you would call first

      A broad segment is hard to test. Describe the early adopters: the people who already feel the problem enough to look for a fix.

    3. 3

      Mark guesses as guesses

      Price, channels and costs are assumptions at this stage. Write the word assumption next to them so you know what still needs a test.

    4. 4

      Pick the riskiest box and test it

      A finished canvas is a list of hypotheses. Choose the one that would sink the idea if it were wrong and talk to customers about it this week.

    Before you trust the canvas

    A lean canvas is a list of guesses, not a plan

    The whole point of the format is that it fits on a page so you can see where your reasoning is thin. The common mistake is to polish the boxes until they look convincing. A canvas that reads well but has never met a customer is still a draft. Fill it in quickly, then change it every time a conversation proves a box wrong. The template cannot tell you whether your idea is any good. It can only make the missing pieces visible, which is where the useful work starts.

    • Keep each box to a few lines
    • Write assumption next to anything untested
    • Redraw the canvas after every customer conversation

    Lean canvas template: common questions

    Is this lean canvas template free?
    Yes. It is free, needs no account, and runs entirely in your browser. Nothing you type is sent to a server, so it is safe to draft an idea you are not ready to share.
    What is a lean canvas?
    A one-page business plan made of nine boxes. Ash Maurya adapted it from the Business Model Canvas for early-stage startups. It swaps four of the original boxes (Key Partners, Key Activities, Key Resources, Customer Relationships) for Problem, Solution, Key Metrics and Unfair Advantage.
    What is the difference between a lean canvas and a business model canvas?
    The business model canvas describes how an established business works. The lean canvas is built for an idea with unknowns, so it starts from the customer problem and asks for metrics and an unfair advantage instead of partners and resources. We compare them in more depth in our article on lean canvas vs business model canvas.
    What do the notes under the canvas check?
    Simple wording rules, not a score. They flag more than three problems, fewer solution lines than problems, a value proposition longer than 25 words, a revenue box with no price or assumption, more than five metrics, and an unfair advantage that is easy to copy. The limits are editorial rules of thumb, not published statistics.
    Does a full canvas mean my idea is good?
    No. A full canvas means you have written down your guesses. It says nothing about whether customers agree. The next step is to pick the riskiest box, usually the problem or the customer, and test it with real people.
    Can I save my canvas?
    The page does not store anything. Use Copy as text to paste the canvas into a document, or Download .md to keep a Markdown file. Do it before you close the tab, because a refresh clears the boxes.
    How long should each box be?
    Short. A line or two per item is enough, and a box that needs a paragraph usually hides two ideas. If you cannot fit the problem in three lines, you probably have not chosen yet.
    Should I fill in the boxes in numerical order?
    The numbers suggest an order that starts with the customer problem and leaves the unfair advantage for last. You can fill the boxes in any order. If you know your solution but not the problem, that is a flag worth noticing.
