Chmod Coach
A guided Unix permissions tutor for coding students that turns terminal errors or screenshots into plain-English causes and the exact chmod or chown command to fix them.
Coding bootcamp students, CS undergraduates, and self-taught devs who freeze whenever they see 'Permission denied' on the terminal
- Screenshot-to-fix: upload a 'Permission denied' terminal error or photo of your TUI and get a plain-English cause plus the exact chmod/chown command
- Interactive rwx grid visualizer where you click owner/group/other cells and watch the octal value and symbolic string update in real time
- Practice drills generated from real-world scenarios: WordPress uploads, SSH key setup, shared git repos, cron job logs, setuid binaries
- Mistake journal that reviews every permission error you got wrong before exams, take-home projects, and technical interviews
Coding bootcamps cover chmod in a single afternoon and students still freeze on real workflows; vision-capable AI now explains terminal screenshots better than any man page, and the rwx GitHub trend (75 stars) shows pent-up demand for friendlier permission tools.
Abundant 'Permission denied' and chmod how-to content (linuxize, GeeksforGeeks, linuxconfig) shows real ongoing confusion, but my bootcamp-specific query returned zero results, indicating the target-student framing is not strongly validated.Fix 'Permission Denied' Error on Linux - LinuxConfig.org ↗
Already crowded: at least 4 free chmod calculators (miniwebtool, devtoolz, dev-toolbox, unixcalculator) plus general AI terminal assistants (Warp, Shellmate, Wing, ai-terminal.dev) that already convert plain English to shell commands and explain errors.Best AI Terminal Assistants of 2026 - Reviews & Comparison ↗Shellmate Terminal Helper ↗
Direct analogues (Shellmate, Wing, Warp, free calculators) are either free or anchor on broader terminal help; a narrow chmod-only tutor has weak paid pull and would compete with free cheat sheets and AI assistants with larger feature surface.AI Terminal Assistants Selection Guide 2026 - Pricing Analysis ↗Unix Permission Calculator - Interactive chmod Calculator ↗
Unix permissions are a 50-year-old fundamental that will outlast this product category; however, terminal AI assistants are rapidly absorbing explain-fix-permission into general-purpose features.
Vision-capable LLMs already screenshot-read terminals well and a chmod reference table is trivial; main work is wrapper UI, not ML.
