Vim Learning Spaced Repetition App

An interactive terminal-based app that teaches Vim keybindings using spaced repetition algorithms. Users learn Vim commands at their own pace with scientifically-optimized review intervals. Target: developers transitioning to Vim, programming students.

Vim adoption has stayed stubbornly flat despite years of Neovim momentum, and most developers who try it quit because muscle memory takes weeks to build without structured reinforcement — spaced repetition directly addresses that dropout point. The closest substitute is Vim Adventures, a browser game that covers basics but doesn't use SRS algorithms or go deep on the full command set. At $500–2k/mo, the math requires roughly 50–200 paying users at a $10/mo price point, which is achievable but tight, and the real ceiling is low because the addressable moment — someone actively learning Vim — is short-lived and one-time. The most likely failure mode is that free alternatives (vimtutor, cheat sheets, YouTube) are "good enough" for the motivated learner, making it hard to convert the audience that actually needs the product.
