Product Canvas
Nine fields that force strategic clarity: problem, solution, unique value proposition, unfair advantage, customer segments, channels, revenue streams, key metrics, and cost structure. The foundation everything else builds on.
Monthly fees for software you already paid to learn. Price hikes you can't avoid. Features removed behind higher tiers. One-time purchase, lifetime access. No recurring charges, no feature gates, no price surprises.
Product Journey is a single-file journey with 17 tools that runs entirely in your browser. Product Journey is a self-contained, browser-based product lifecycle toolkit delivered as a single HTML file. It organises product creation into four phases: Envision (Product Canvas, User Personas, Feature Brainstorm), Build (Sprint Planner, Pipeline Tracker, Copywriting Lab), Grow (Experiments, Metrics Dashboard, Competitive Arena), and Launch (Pricing & Revenue with 12-month projections, Runway Calculator, Growth Timeline, Milestone Roadmap, Summary Report). Cross-phase tools include Library (templates and examples), Help (onboarding), and Files (multi-project JSON management with 50-step undo). Your roadmap, pricing strategy, and competitive intelligence never leave your machine.
