Developers waste time switching between coding and tutorial resources when learning new tools like Vim.
Build embeddable, interactive tutors that run directly in browser-based IDEs (VS Code, Gitpod, etc). These would demonstrate commands and provide real-time feedback as users practice.
Monetize through marketplace sales to IDE extension stores and custom integrations for engineering education platforms.
MVP could be a single-topic tutor (like Vim motions) packaged as a VS Code extension.
Risk: IDE vendors might build this functionality natively.
