Development

CSV Malformed Row Surgeon

Surgically repair malformed CSV rows one at a time: unescaped (stray) quotes, mixed delimiters (tab/semicolon/comma in the same file), BOM-prefixed headers, CRLF/CR line endings and trailing empty lines. The surgeon parses tolerantly, shows a row-level red/green diff of every change it made (before → after, with the repair reason tagged), lists the rows it accepted unchanged, and emits the cleaned CSV. Optional AI repair can review suspicious rows after the deterministic pass. It complements the CSV Validator (which only reports problems) by actually fixing the damaged rows.

Development

CSS Beautifier

Format and beautify minified or messy CSS code into readable, well-indented stylesheets

Development

CSV Header Alias Resolver

Map messy CSV headers onto a clean target schema. Paste a CSV whose first row holds inconsistent column names (Customer ID, user_id, customerId, CUST_ID…) plus your target schema (one column per line) and an optional "alias=target" dictionary. Each source header is resolved through four layered passes — exact, dictionary, normalized (strips case/accents/separators/camelCase), then fuzzy edit-distance — and shown in a mapping table with method and confidence, plus target coverage and an optional normalized CSV export.

Data Processing

CSV Validator

Validate CSV structure, detect malformed rows, unbalanced quotes and column mismatches

Format Conversion

Caesar Cipher

Encode, decode, and brute-force the Caesar cipher with any shift (1–25), or print all 25 candidate decodings.

Text Processing

Capitalize Sentences

Capitalize only the first letter of each sentence while preserving all other letters exactly as typed. Fixes sentence starts without disturbing acronyms, proper nouns, or intentional mixed-case.

Data Visualization

Central Limit Theorem Demonstrator

See the Central Limit Theorem in action: draw samples from a non-normal source distribution (uniform, exponential, Poisson, or Bernoulli), plot the histogram of sample means, and overlay the predicted Normal curve N(μ, σ²/n). Compare empirical vs theoretical mean and standard error, and watch convergence tighten as the sample size grows.

AI Tools

AI RAG Chunk Quality Scorer

Score candidate RAG chunk-splitting schemes for a document across four metrics — coherence (clean sentence/paragraph boundaries), coverage (topic focus / key-term concentration), context overlap health, and chunk-size consistency — then compare up to three schemes side by side and recommend the best. Pure offline heuristics, no model calls.

Science & Education

Codon to Amino Acid Translator

Translate a DNA or mRNA sequence into protein using the standard genetic code. Scans all 6 reading frames (forward and reverse complement), marks start (AUG) and stop codons, identifies the longest open reading frames (ORFs), and shows the amino-acid composition with color-coded residue types. Supports T→U normalisation and reverse-complement translation.

Design

CSS Target Color Filter Generator

Solve a CSS filter chain that closely reproduces a target hex color from a monochrome base color

Text Processing

Cursive Text

Render text in hand-written cursive Unicode — delicate Script (ℋℯ𝓁𝓁ℴ) or heavier Bold Script (𝓗𝓮𝓵𝓵𝓸). Plain Unicode text, no font needed.

AI Tools

AI Prompt A/B Variant Generator

Generate controlled A/B variants of a prompt across the persona, tone/style, output format, and constraints dimensions, then compare them side by side with a heuristic rubric score and a word-level diff against the baseline. A reproducible way to test how a prompt behaves under different framings before picking one for production.
