Free Business Model Canvas

What a Business Model Canvas actually is

A Business Model Canvas is a single page divided into nine blocks that describe how a business creates, delivers, and captures value. Alexander Osterwalder and Yves Pigneur popularised it in Business Model Generation (2010), and its whole premise is the constraint: nine questions, one page, no room to hide behind a long document. Filling it in forces the parts of the business that do not fit together into the same small space, where the mismatch is hard to ignore.

The honest caveat is that it is a thinking tool, not a business plan and not a forecast. It holds no numbers, no timeline, no competitor analysis, and nothing that proves a customer will pay. What it does well is expose the contradictions between what you claim to offer, who you claim to serve, and where the money is supposed to come from — which is usually the part of the plan that has not been thought through.

The nine blocks, briefly

Each block answers one question, and each has a characteristic way of going wrong. If you can name the mistake before you write, you will avoid most of it.

Customer Segments

The specific groups of people or organisations you serve, described by the job they are trying to get done rather than by age or income. The usual mistake is writing "small businesses" or "everyone who needs X" — a segment you cannot name three real examples of is not a segment.

Value Propositions

The outcome each segment gets, stated as relief from a specific alternative they use today. The usual mistake is listing features or products instead of the change in the customer’s situation.

Channels

How each segment finds you, evaluates you, buys, and receives what they bought. The usual mistake is listing every channel you could theoretically use rather than the one or two that actually deliver customers at a cost you can survive.

Customer Relationships

The mechanics of getting, keeping, and growing a customer: onboarding, support, renewal, and what happens when something goes wrong. The usual mistake is writing "friendly service" — that is an intention, not a mechanism.

Revenue Streams

Who pays, for what, how much, and how often — including the pricing mechanism, not just the category. The usual mistake is writing "sales" and leaving out price, frequency, and whether the payer is the same person as the user.

Key Resources

What you must own, control, or have reliable access to in order to deliver the value proposition. The usual mistake is listing software and equipment — the resources that matter are the scarce ones that are expensive or slow to replace.

Key Activities

The few recurring things your business must do well, every week, for the model to work. The usual mistake is copying a to-do list into the block instead of naming the activities the business depends on.

Key Partnerships

The suppliers, platforms, regulators, and intermediaries you depend on but do not control. The usual mistake is listing everyone you buy from — a partner is someone whose failure or price change would hurt you.

Cost Structure

What it costs to run the model, separated into what is fixed, what scales with volume, and what dominates. The usual mistake is averaging everything into one number, which hides the cost that actually decides whether you can grow.

How to fill it in without fooling yourself

The method matters more than the template. Start by filling the board divergently: pick a block, add notes quickly, and resist tidying the wording as you go. A first pass should take twenty minutes and produce a board you are not proud of. Then stop, leave it, and return in a separate sitting whose only job is critique — deleting notes that are wishful, merging duplicates, and moving anything that is in the wrong block.

The faint numbers on the canvas show a suggested path: start with Customer Segments on the right, then Channels, Key Activities, Cost Structure, Key Resources, Key Partnerships, Customer Relationships and Revenue Streams. Finish with Value Propositions, which should describe the value the rest of the board can actually support.

The 140-character cap on every note is deliberate rather than a technical limit. If an idea does not fit, it is almost always two ideas, and splitting it forces you to say which one you mean. That is also why the notes are cheap to move and cheap to delete: the point is to change your mind quickly.

In the canvas above, every block has an Add note button. While typing a note, Enter saves it, Shift+Enter starts a new line, and Esc cancels without saving. Cmd/Ctrl+Z undoes and Cmd/Ctrl+Shift+Z redoes, keeping the last thirty changes; inside a note field those shortcuts stay with the text, so your typing undo behaves normally. To relocate a note, use the Move control on it and pick one of the nine blocks.

Why sticky notes rather than a spreadsheet

A spreadsheet rewards completeness. Its cells are the same size, they accept any amount of text, and nothing about the format pushes you to decide anything. Sticky notes reward the opposite: the small square forces one idea, the physical metaphor makes position meaningful, and the whole surface is visible at once instead of scrolled through a grid.

Moving a note is thinking. When you take a note out of Key Activities and put it into Cost Structure, you have just decided that someone has to pay for it — a decision a spreadsheet would let you avoid by adding a row. Deleting a note is cheap for the same reason: you never invested in formatting it, so you have nothing to defend. The tool renders the notes as paper-like squares with a slight, deterministic tilt so the board reads as a working surface rather than a form to complete.

Using this tool

The canvas gives you the nine standard blocks, each with a short prompt to keep you on the question. Every note is capped at 140 characters, and the board autosaves to this browser as you work — the toolbar shows a Saved confirmation, or tells you if browser storage is unavailable. New canvases start with a Project name and a Short description of at least ten words before the board opens. Existing boards reopen directly. The name is capped at 80 characters and the description at 240. You can edit both above the board. Both are saved with the rest of the canvas, travel in the JSON export and import, appear in print, and are drawn into the exported PNG. Each block also has an optional AI button that drafts a few note ideas from the project name, description and board; add a project name and a description of at least ten words to enable it. Nothing is added until you accept a draft. The Two-sided business switch adds an A/B toggle to each note, colouring supply notes green and demand notes blue, which is useful when one business serves two distinct groups. Export PNG downloads a branded 3200px-wide image of the whole board, with the Lugetech logo, the title Business Model Canvas 4 All and a by Lugetech byline — usually the easiest thing to send to someone. Export JSON downloads the board, Import JSON loads one back (and warns before replacing what is there), and Print creates a compact report grouped by block, with every accepted note in full and A/B labels for two-sided boards. Large boards continue onto additional pages; unaccepted AI drafts are excluded. Choose Save as PDF in your browser’s print dialog to keep a copy. On phones the toolbar collapses to a compact bar, a block rail jumps straight to any of the nine blocks, and the file, print and reset actions open from the Canvas actions menu. Undo and Redo cover the last thirty note changes. Start over clears the notes, project title and description; note removal can still be undone. There is no PDF export, no drag-and-drop, no account, and no sharing link.

Marketplaces and two-sided businesses

If your business has two distinct sides — drivers and riders, sellers and buyers — the standard nine blocks will fight you, because every block wants a single answer. We wrote a separate guide on splitting the canvas for two-sided marketplaces, including a worked example and what a real board usually gets wrong. The tool uses the same convention: A is supply and green, B is demand and blue, notes without a side stay amber, and while Two-sided business is on the toolbar legend reads A · Supply and B · Demand. Use Rename sides to name them for your business, such as Drivers and Passengers. The colours and provider/customer roles stay the same, and the names travel with saved boards and exports.

Limitations

Be clear about what this is. Your board is saved in this browser only, under this site’s local storage, so it does not follow you to another device or another browser. Clearing your browsing data, using a private window, or switching machines will lose it — export a JSON backup whenever a board matters. There are no accounts, no collaboration, and no live sharing. AI assist is optional and only sends anything when you click the AI button in a block: the project name, the short description, side names and the board’s notes go through our serverless endpoint to OpenRouter to draft a few notes, which you accept or dismiss. The endpoint does not store your canvas or log prompts, and outside that, nothing you type leaves this browser. The privacy page has the details. If your browser blocks local storage, the toolbar will say so rather than silently losing your work.
