Built on Amazon Nova, daily-capped to stay free.
Analysis
Analyze and inspect Markdown documents

CLAUDE.md Reviewer
Claude Code reads your CLAUDE.md every session, so every vague or unused line costs tokens and weakens behavior.

Passive Voice Detector
Paste a draft and find likely passive voice patterns such as be verbs followed by past participles. The detector highlights matching sentences so you can decide whether to rewrite them in active voice.
Word Frequency Analyzer
Paste an article, transcript, landing page, or draft and see the most frequent words and repeated two-word phrases. Toggle stop words to inspect either topical terms or raw language patterns.
JSON Diff & Compare
Paste two JSON snippets and instantly see the structural differences. Toggle 'sort keys' to compare structurally (ignoring key order) — useful when comparing API responses, config files, or data dumps where key order varies. Shows a colored line-by-line diff with added/removed counts and a copyable unified diff. Validates each side independently and shows parse errors inline. Everything runs in your browser.
AI Text Detector (Free, In-Browser)
Paste any text and see how likely it was AI-generated, scored 0-100 from 12 transparent, explainable heuristics: sentence-length burstiness, lexical diversity (MATTR), AI vocabulary clustering (delve, tapestry, leverage), em-dash density, negative parallelisms, rule-of-three triplets, transition-phrase density, and more. Every heuristic's contribution is shown so the score is never a black box. 100% client-side — your text never leaves your browser. This is a transparent smell-test, not proof: heuristic detection produces false positives on formal, academic, and non-native-English writing, so never use it for accusations or grading.
Formatters
Clean up and format Markdown
LinkedIn Text Formatter
LinkedIn has no built-in rich-text editor, so this LinkedIn text formatter converts your text into Unicode characters that display as bold, italic, bold italic, underline, strikethrough, double underline, script, monospace, and other fancy fonts — ready to paste into LinkedIn posts, comments, headlines, and your About and Experience sections. Type your text and every style updates live; click copy and paste it into LinkedIn. Add eye-catching bullet points (•, →, ✓, ★) with one click. It runs entirely in your browser, so your text is never uploaded — completely free, instant, with no signup, no watermark, and no usage cap. Important: Unicode-formatted text is not searchable on LinkedIn, is not read correctly by screen-readers, and counts as more characters, so use it sparingly for headings and short attention-grabbing snippets.
Discord Text Formatter
Discord supports native markdown formatting (**bold**, *italic*, ~~strikethrough~~) in messages, but markdown does not work in usernames, nicknames, or server names. Unicode Mathematical Alphanumeric Symbols are the only way to style those fields — and they work in chat messages too if you want a different look. Type your text and every style updates live; click copy and paste it into your Discord username, server name, nickname, or message. Runs entirely in your browser — completely free, instant, with no signup, no watermark, and no usage cap.
Clean Pasted Text
The fix for text that copied wrong. Paste anything that picked up junk on the way to your clipboard and get clean plain text back: the vertical quote bars (▎ │ ┃) ChatGPT and terminals prepend to quoted lines, leftover ANSI color codes like [1m and [22m, curly smart quotes, em/en dashes, ellipsis characters, zero-width and non-breaking spaces, and paragraphs that got duplicated when the source rendered the same block twice. Six independent toggles, live before/after preview, and a per-fix change count. Runs entirely in your browser — nothing is uploaded.
AI Output Cleaner
Paste AI-generated content and instantly remove common artifacts: 'Certainly!' openers, trailing disclaimers, excessive formatting, em dashes, and filler phrases. Makes AI output sound human.
Remove Em Dashes
The em dash is AI's favorite punctuation mark. Paste any ChatGPT, Claude, or Gemini output and remove em dashes (—), en dashes (–), and replace 20+ AI vocabulary words like 'delve into', 'leverage', 'landscape', 'seamless', 'robust', and 'tapestry' with plain alternatives. Also fixes 'it's not just X, it's Y' patterns. Runs entirely in your browser. No uploads.
Humanize AI Text
Paste ChatGPT, Claude, or Gemini output and get a rewrite that sounds human. Removes AI vocabulary (delve, leverage, robust, tapestry), em-dash overuse, forced rule-of-three triplets, inflated symbolism ('marks a pivotal moment'), promotional language ('nestled, breathtaking'), conversational artifacts ('Certainly!'), and 15+ other patterns identified by Wikipedia's Signs of AI Writing project. Powered by Amazon Nova Micro on AWS. Daily-capped to stay free.
LinkedIn Post Enhancer
The Enhance Post button that doesn't sound like AI. Paste your LinkedIn draft, pick a goal — stronger hook, shorter, more professional, story structure, or just de-slop — and get back a sharper post that still sounds like you. It never adds the tells LinkedIn's built-in AI is famous for: no 'thrilled to announce', no em dashes, no delve/leverage/unlock buzzwords, no forced triplets, no hashtag spam, no motivational-poster endings. Your facts, numbers, names, and links are preserved; nothing is invented. Output is plain text formatted for LinkedIn (short 1-2 line paragraphs, hook under 60 characters, 3,000-character limit tracked). Free, no signup, daily-capped.
Refine Content
Paste any text — an email, ticket description, doc section, blog paragraph, or Markdown — pick a refinement, and get it back improved. Six refinements: shorten (cut ~50% while keeping every point), expand (elaborate without inventing facts), rephrase (same meaning, new wording), simplify (plain 8th-grade language), fix grammar (minimal edits, your voice intact), and change tone — professional, friendly, confident, casual, or fun tones like Gen Z slang, millennial, Shakespearean, and pirate speak. Markdown formatting, facts, names, and links are preserved. Stack refinements by feeding the output back as input. Powered by Amazon Nova Lite on AWS Bedrock. Daily-capped to stay free.
Markdown Snippet Cleaner
Fix common issues when pasting content from Notion, Google Docs, Slack, or other sources: smart quotes to straight quotes, non-breaking spaces, zero-width characters, inconsistent line breaks, and broken list formatting.
Markdown Table Formatter
Paste a messy Markdown table and get it properly padded, aligned, and formatted. Fixes inconsistent spacing and pipe alignment.
Markdown Prettifier
Normalize heading styles, list markers, blank lines, and spacing across an entire Markdown document. Choose ATX or Setext headings, dash or asterisk lists, and more.
List Sorter
Paste a Markdown list (bulleted or numbered) and sort items alphabetically, in reverse, or by line length. Handles nested lists and preserves indentation.
URL Reference Converter
Convert all inline links [text](url) to reference-style [text][ref] with definitions at the bottom, or convert reference links back to inline. Keeps your document clean.
XML Formatter & Validator
Paste XML and instantly format it with indentation, minify it, or validate that it is well-formed. Useful for DITA topics, RSS feeds, SVG, sitemap XML, SOAP payloads, and config files. Runs entirely in your browser using DOMParser, so nothing is uploaded.
Bug Report Formatter
Paste half-formed bug notes — a description, some steps you tried, maybe an environment detail — and get a structured, triage-ready bug report: clear title, numbered Steps to Reproduce, Expected vs Actual behavior, Environment section, estimated severity, and flags for missing info the developer will ask for anyway. Formatted in GitHub-Flavored Markdown for GitHub, GitLab, Jira, Linear, and Notion. Powered by Amazon Nova Micro on AWS Bedrock.
AI JSON Repair (Fix Broken JSON)
Paste JSON that's almost-but-not-quite valid — from an LLM response, a log file, a half-broken config, or someone's hand-typed mess — and get back clean valid JSON with a visual diff showing exactly what changed. Handles trailing commas, unquoted keys, single quotes, Python True/False/None, JavaScript undefined, comments, surrounding prose, and markdown code fences. Built on Amazon Nova Micro (cheap and fast). Daily-capped to stay free.
LLM JSON Extractor (ChatGPT, Claude, Gemini)
Paste any LLM response — even one full of prose, markdown headings, code fences, summaries, and commentary — and get back just the JSON it contains, cleaned and valid. Designed for developers building on Claude / ChatGPT / Gemini APIs who need a quick paste-and-fix when JSON-mode isn't enforced. Handles multiple JSON blocks (returns them as an array), Python-style booleans, trailing commas, and the usual LLM output quirks. Built on Amazon Nova Micro.
Utilities
Reference guides and power-user tools
Markdown Cheat Sheet
Complete Markdown syntax reference with live rendered examples side by side. Covers standard Markdown, GitHub Flavored Markdown, and common extensions.
Regex Find & Replace
Search your Markdown with plain text or regular expressions and replace matches with live preview. See highlighted matches before applying changes.
YAML Frontmatter Editor
Build and edit YAML or TOML frontmatter visually. Add fields like title, date, tags, and categories through a form, then copy the formatted frontmatter block.
Transcript Cleaner
Paste a raw transcript from YouTube, Zoom, Otter.ai, or any auto-captioning tool and get clean, readable text. Removes timestamps, SRT sequence numbers, speaker labels, filler words (um, uh, like), stutters, and merges broken caption lines into proper paragraphs.
Base64 Encode/Decode
Encode any text (including Unicode/UTF-8) to Base64, or decode Base64 strings back to readable text. Works entirely in your browser - no data is sent to any server.
HTML Entity Encoder/Decoder
Convert special characters like <, >, &, and quotes to their HTML entity equivalents, or decode HTML entities back to readable text. Includes a reference table of common entities.
Color Converter
Enter a color in any format (HEX, RGB, or HSL) and see it converted to all other formats instantly. Includes a live color preview and one-click copy for CSS variables and Tailwind classes.
Regex Tester
Build and debug JavaScript regular expressions with live feedback. Toggle flags (g, i, m, s, u, y), see every match highlighted in your test string, inspect numbered and named capture groups in a table, and switch to Replace mode for a live preview of the substituted output. Fully client-side, uses your browser's native RegExp engine so behavior matches what you'll see in production JS code.
Text Repeater
Type text once, choose a repeat count up to 10,000, pick a separator, and copy the repeated output. Useful for test data, placeholders, repeated phrases, and quick text generation.
Password Generator
Generate cryptographically secure passwords in your browser. Adjust length (4-128), toggle uppercase / lowercase / numbers / symbols, optionally exclude ambiguous characters (i, l, 1, L, o, 0, O). Shows real-time entropy in bits with a strength label. Generate 1-20 passwords at once, copy with one click. Built on the Web Crypto API — no random number predictability, no server roundtrip, no logging.
Token Counter & Cost Estimator (Claude, GPT, Gemini, Nova)
Paste any text and see token counts + USD cost across every major LLM provider — OpenAI (GPT-5, GPT-4o, o1), Anthropic (Claude Opus 4.5, Sonnet 4.6, Haiku 4.5), Google (Gemini 2.5 Pro/Flash), Amazon (Nova Micro/Lite/Pro), DeepSeek, xAI Grok, Mistral. OpenAI counts are exact (gpt-tokenizer / o200k_base BPE). Other providers use character-based estimates because they don't publish browser-runnable tokenizers — drift is clearly labeled. Choose input-only, output-only, or 50/50 mix; project cost at 1 to 1M calls. All client-side, no signup.
