AI Tools
AI-powered image content safety detector using NSFWJS to classify potentially inappropriate content with fallback analysis, supporting GIF/Animated WebP/APNG and JPEG/PNG/WEBP.
Text Processing
Convert AI-typical plain ASCII into proper typography: -- and --- become en/em dashes, straight quotes become curly/smart quotes (locale-aware), ... becomes a single ellipsis …, spaced dashes are tightened, and repeated spaces collapse — while fenced ``` code blocks and `inline` code are left untouched.
Design
Generate a clean, copy-paste HTML email signature that renders correctly in Gmail, Outlook, and Apple Mail — with avatar/logo, social icons (auto-detected from your links), accent color, light/dark/auto theme, and a table-based email-safe layout using inline styles. Copy the raw HTML and paste straight into your mail client.
Validation
Validate 8-digit EAN-8 / GTIN-8 product barcodes with check-digit verification, GS1 country prefix and packaging breakdown.
Media
Convert FLAC audio files to ALAC (Apple Lossless) in an M4A container while preserving lossless quality and metadata when available
Security
Compute an HMAC message-authentication signature over a message + shared secret using SHA-1/SHA-2/SHA-3/BLAKE2, or verify an incoming signature against the secret — with webhook presets for Stripe / Slack / GitHub and constant-time comparison
Extract a dominant color palette from an image (k-means clustering), then export it as CSS variables, SCSS variables, a Tailwind config, or JSON design tokens — with named colors and an auto-generated shade scale for each
