Collection of web-based utilities for everyday tasks.

Three-point task estimation with confidence ranges, grounded in Robert C. Martin's point in The Clean Coder that an estimate is a probability range, not a commitment.

Features:

• Optimistic / nominal / pessimistic per category (impl, review, testing, polish, client comms)
• PERT expected value (μ = (O+4N+P)/6) and combined uncertainty (σ = √Σσᵢ²)
• ~68% and ~95% confidence bands with a live bell curve
• Rough (optimistic-only) vs detailed two-phase workflow
• Newness multiplier for greenfield work, Fibonacci buckets, review-as-%-of-impl
• Live LaTeX formula rendering (KaTeX)
• Client-side only (no data sent to servers)

Usage: Open estimator.html in your browser.

Split long messages into Discord-compatible chunks (2000/4000 character limits).

Features:

• Automatic splitting with newline awareness
• Collapsible preview (first/last 100 chars)
• Copy-to-clipboard with auto-hide
• Restore functionality
• Client-side only (no data sent to servers)

Usage: Open discord_message_splitter.html in your browser.

Find the smallest word that matches two regular expressions using NFAs.

Features:

• NFA simulation with Thompson's construction
• Pair comparison mode for checking two regexes
• Bulk uniqueness checking for multiple patterns
• SVG-based NFA visualization
• Supports literals, concatenation, alternation, Kleene star, plus, optional, and grouping
• Client-side only (no data sent to servers)

Usage: Open regex_intersection_checker.html in your browser.

All tools are standalone HTML files. Open directly in any modern browser. Shared look-and-feel lives in style.css (a small self-contained stylesheet, no framework).
