# It’s Fully Online — Browser-Native Tools for AI Agents ## Overview A free collection of 145 privacy-focused browser-native tools for AI agents. Most tools run as vanilla ES modules in your runtime; a subset (image conversion, PDF/DOCX generation, and a few analysis tools) runs server-side through the public connector API. No accounts, no tracking, no data uploads, no API keys. ## How Tools Work - **AI agents:** Fetch `https://itsfullyonline.yunusemrevurgun.com/api/manifest.json` for the full tool catalogue. Tools with a `clientModule` are imported as ES modules and executed by calling the exported `execFunction`. Tools without one are executed through the connector API (below). - **API access:** POST to `/backend/connector-api.php?action=execute` with `{"tool": "slug", "data": {...}}` payload. No token needed. Server-side tools execute directly; browser tools return execution instructions. ## Tool Categories ### Text Tools Word & Character Counter, Text Editor, Email Subject Line Length Checker, Markdown Previewer, Smart LaTeX Editor, Resume ATS Formatting Checker, Text Color Changer, Whitespace & Line Cleanup, Copy-Paste Cleanup for AI Outputs, Remove Invisible Characters, WhatsApp Message Formatter, Tweet/X Character Counter, Discord Markdown Formatter, Text Similarity Comparator, Language Detection + Reading Level, Duplicate Line Finder + Remover, Smart Text Cleaner & Rewriter, Advanced Regex Extractor, Text Diff Viewer, Named Entity Highlighter, Text Entropy Calculator, Base64 Text Encoder/Decoder, Text Template Filler, Bulk Text Find & Replace, Lorem Ipsum Generator, Text to Slug Converter, TF-IDF Text Summarizer, Named Entity Extractor, Text Diff & Patch Visualiser, Extractive Text Summarizer, Regex Tester & Explainer, Structured Data Extractor, Text Chunker for RAG Pipelines, Citation & Reference Formatter, Tone & Sentiment Analyser, Prompt Optimizer for LLMs ### File Converters TXT ↔ DOCX Converter, TXT to PDF Converter, Image Converter (JPG/PNG/WebP), Image Compressor, Image Resizer, SVG to PNG Converter ### Developer Tools Image to Base64, JavaScript ES6 Vanilla Syntax Validator, JSON Formatter & Validator, JSON Validator/Beautifier/Minifier, JSON Key Sorter, CSV to JSON (Flattened), CSV Delimiter Detector, Sensor CSV Trend Detector, CSV Auto-Profiler, UUID Generator + Validator, Epoch Timestamp Batch Converter, What Is My User Agent?, Base64 Media Encoder/Decoder, Color Format Converter (HEX/RGB/HSL), Cron Expression Parser & Builder, URL Encoder/Decoder ### Security Tools Password Generator, Passphrase Generator, WebGL Fingerprint Detector, WebGPU Fingerprint Detector, JWT Decoder & Analyzer, Hash Type Identifier, Password Strength Auditor, Password Strength Analyzer, Security Headers Checker, Vulnerability Pattern Scanner, Entropy & Randomness Analyser, Code Security Auditor, HTTP Header Security Analyser ### Privacy Tools Image EXIF Viewer + Remover, Canvas Fingerprint Detector, Audio Context Fingerprint Detector, Font Fingerprint Detector, Document Cleaner & Redactor ### Design Tools Color Palette Extractor, Color Contrast Checker (WCAG), Organic Random Shape Generator, Browser Paint with Smart Palette, SVG Optimizer & Analyser, Image Color Picker, Image Histogram Viewer ### Media Tools MP3 Trimmer, MP3 Audio Effects, YouTube Title Length Checker, Reddit Title Character Counter, Text to Audio Morse Code (MP3), Neural Network Pi Sound Generator, QR Code Generator, QR Scan Reliability Predictor, Audio Frequency Visualizer, GIF Frame Extractor, Audio Waveform Analyser, Video Metadata Parser, Image Metadata Analyser ### Utility Tools What Is My Geolocation?, What Is My IP Address?, What Is My Timezone?, What Is My Network Information?, What Is My Screen Size?, Timezone Meeting Overlap Finder (2-4 Zones), Smart Mindmap Generator ### Other Tools Solar Flare Tracker, Visual Neural Network Grid ### AI & ML Tools K-Means Clustering, Confusion Matrix Calculator, Linear Regression Analyzer, Naive Bayes Text Classifier, Linear Regression & Feature Correlation ### Math Tools Derivative & Integral Calculator, Fourier Series Visualizer, Matrix Calculator, Statistics Significance Tester, Numerical Differentiation, Numerical Integration, Matrix Operations Suite, Taylor Series Expansion ### Physics Tools Projectile Motion Simulator, Wave Superposition Simulator, Pendulum Wave Simulator, Ideal Gas Simulator, Electric Circuit Analyzer, Pendulum Calculator, Circuit Analyzer, Wave Interference Simulator, Thermodynamics Calculator, Orbital Mechanics Calculator, Wave & Oscillation Analyser, Electromagnetic Field Calculator ### SEO Tools LLMs.txt / AI.txt Generator, Structured Data (JSON-LD) Validator, Meta Tags SEO Analyzer, Robots.txt Tester, Canonical URL Checker, Keyword Density Analyzer, OpenGraph & Twitter Card Validator, Page SEO Auditor, Robots.txt & Crawl Budget Analyser, AI/LLM Visibility Checker, Content Gap & Semantic Keyword Analyser, XML Sitemap Validator & Analyser ## Publication **Agentic AI in the Browser** — a practical guide to privacy-first, browser-native agentic workflows.
