Generates random integers within a user-defined min-max range with optional unique and sorted output. Uses the browser random number generator — fine for games, raffles, and sampling, not for security secrets. Input never leaves your device — everything runs locally in your browser.
Let the wheel decide — pros/cons scoring plus random pick for stuck choices. End analysis paralysis in 60 seconds — free, local, no signup.
Takes any long URL and generates a compact, shareable short link. Uses cloud-based processing. Short links resolve through managed providers with automatic failover — free, paced ~10 links/min per address.
Generate strong yet memorable passwords — word-based passphrases with real entropy. Get correct-horse grade security you can type — local crypto, free, no signup.
Analyzes your writing with real-time word count, character counts with and without spaces, sentence and paragraph counts, plus estimated reading time (200 wpm) and speaking time (150 wpm). Essential for writers, students, and SEO professionals tracking length and pacing.
12 characters minimum for everyday accounts (≈79 bits of entropy from a 94-character set); 16+ (≈105 bits) for email, banking, and password-manager master passwords. Every extra character multiplies guessing effort ~94×.
Random strings pack more entropy per character; 5-word passphrases are easier to type and remember. Use random for stored-in-manager logins, passphrases for the few you must memorize.
Uppercase + lowercase + digits + symbols gives the full 94-character set. Some legacy sites reject symbols — the generator lets you exclude them without weakening length, which matters more than variety.
No. One breach exposes the pattern. Generate a unique password per site and store them in a password manager — that is the threat model this tool is built for.
No. Generation uses the browser Web Crypto API locally. Passwords never leave your device and are never logged.
The meter maps entropy: Strong at 120+ bits, Good at 80+, Fair at 60+, else Weak. A 16-char all-sets password lands around 105 bits (Good); the Bank/Secure preset (24 chars) lands around 157 bits (Strong). The length slider itself runs 4-64.
