An elegant idea buried in a sea of redundancy.
AI roast score: 55/100 (D)
The idea
An elegant HTML plan generator? Yawn. The market is flooded with tools that do more, better, and with less friction.
In the founder's own words
plannotator/effective-html — Agent skill for elegant and simple html plans, architecture diagrams, or whatever else you can think of.
HTML skills for pragmatic visual artifacts

Note: The diagram was made by Fable 5 , I will create more fable 5 artifacts and add them to the skill folder for smaller models to distill.
example demo
Focused skills for generating self-contained HTML deliverables with a strong visual bias:
html : an HTML file for whatever you're describing, in the effective HTML style
html-diagram : architecture, stack, and systems understanding rendered as full-screen HTML diagrams with high-quality SVG
html-plan : HTML plan pages in the effective HTML style
Render and annotate your HTML with Plannotator (optional): https://github.com/backnotprop/plannotator

The roast
Your pitch for a tool that generates HTML plans and diagrams is painfully late to the party. The market is suffocated with similar offerings, from Figma to Lucidchart, and frankly, the world doesn't need another one. Your unique selling point is just 'simpler' when the complexity is what drives innovation. Plus, with only a solo effort and no funding, your execution capability looks shaky at best. It's hard to see how a subscription model can scale when you're essentially recreating features that are already standard in existing tools.
Red flags
- Lack of any competitive differentiation beyond simplicity.
- Solo founder with no funding indicates limited capacity for growth.
- Market is saturated with established players offering more robust solutions.
Verdict
Reassess the need for your product in a crowded space before proceeding.
