About CyberScryb

One person, a laptop, and a lot of late nights.

Why this exists

I am a solo founder. I started building these tools in 2026 while working night shifts as a CNA in a memory care facility. During 12-hour overnights, I had 10-15 minute windows between patient rounds to write code on my phone or laptop.

Most free developer tools online gate access with email forms. You paste your data, the companies collect your info, then they ask for subscription fees. I built alternatives to stop this. The dev tools process everything locally in your browser — no server calls, no database entries, no tracking pixels. The AI tools are the exception: they need a backend to generate results, so your input goes to an AI API for that one step.

What's here

• Anti-AI Humanizer: paste ChatGPT output for text in your own voice
• JSON to CSV Converter: convert in both directions, handle nested objects, process 50,000 rows
• Password Strength Checker: view entropy and estimated crack time without sending data online
• SEO Meta Tag Generator: generate title, description, OG, and Twitter tags
• Base64 Encoder/Decoder: encode or decode text
• Color Palette Generator: pick a base color for matching shades with contrast scores
• Markdown to HTML Converter: type markdown to see live HTML rendering
• Gig Auto-Pilot: write freelance proposals and draft deliverables

How the math works

I don't make stuff up. The calculations behind these tools are based on real standards and published research:

• Password entropy uses Shannon's formula: H = L × log₂(N) where L is the length and N is the pool of possible characters
• Crack time estimates assume modern GPU speeds (RTX 4090-class, roughly 121 billion MD5 hashes per second)
• Color contrast ratios follow WCAG 2.1 compliance
• JSON and CSV parsing follows RFC 8259 and RFC 4180 respectively
• Base64 implements RFC 4648, both standard and URL-safe

Privacy, for real

The dev tools (password checker, JSON/CSV, SEO tags, and the rest) run entirely in your browser with JavaScript — no server-side processing. The benefits:

• Your passwords never leave your computer
• Your JSON and CSV data stays on your machine
• SEO tags get generated locally
• I don't use tracking cookies
• No analytics scripts that phone home with your personal info

The AI tools (Humanizer, Gig Auto-Pilot, Summarizer, and the rest) are the one exception — they send your input to an AI backend to generate the result. That's the only place your data leaves the browser, and nothing is stored beyond generating what you asked for.

Under the hood

The whole site is vanilla HTML, CSS, and JavaScript. No React, no Next.js, no build step. I did this on purpose:

• Loads fast: no framework overhead to download
• Works offline: no server calls needed once loaded
• No supply chain risk: zero npm dependencies in the browser code
• Read the code: right-click, view source, see running scripts

How the tools work (100% Free & Private)

Every tool on CyberScryb is built with simplicity, speed, and privacy in mind:

• Client-side tools (JSON↔CSV, Base64, password checker, regex, medical dispute letter, security deposit demand, etc.) are 100% free forever with no account needed. They run entirely in your browser—your data never leaves your device.
• AI writing & document tools (Humanizer, Summarizer, Gig Auto-Pilot, Hardship letters, and appeals) generate full outputs without paywalls or required subscriptions. Fair usage limits protect server capacity and prevent abuse.
• Zero accounts, zero paywalls: No logins to manage, no recurring subscription charges, and no hidden trial traps. Just visit, run your tool, copy or export your results, and get on with your day.
