Unfair advantage

JSON backups are needed to resume later. CSV and PDF are report snapshots. Large reports stop at 40 pages. This PDF uses one landscape page and rejects text that cannot fit.

Nothing is saved automatically. JSON backups are readable, unencrypted files. Export before closing. PDFs support Latin, Greek and Cyrillic text.

How privacy works

How it works

Complete the nine business-model blocks, build the report and review a three-by-three canvas. Export CSV, a one-page PDF or JSON to continue editing.

Supported formats

Nine blocks up to 1,200 characters each; CSV, one-page landscape PDF and JSON. Long blocks must be shortened to fit the print layout.

Good to know

This is a planning canvas, not market research or financial forecasting. The blocks do not validate demand, profitability or competitive advantage.

Worked example

Before

Problem: shops need regular graphics; segment: independent retailers; revenue: monthly service fee

After

Nine clearly labeled blocks showing the proposed business model

The tool preserves your hypotheses without claiming that a subscription business will succeed.

Make assumptions testable

Describe a specific customer and problem, then identify the measures you would use to test the proposed solution. Export a snapshot for discussion and retain JSON for revisions.

Troubleshooting

Why is my Lean canvas PDF rejected?

A section or title exceeds the fixed page’s available space. Shorten the named block; text is never deliberately truncated to force a fit.

Common questions

Is this the same as a complete business plan?

No. It is a concise nine-block summary. Detailed operating plans and forecasts need separate work.

Can I use this without an internet connection?

Yes, after you prepare this tool from Offline help and the browser retains its assets. Installation is optional. All processing dependencies are bundled locally.
