The Character Counter gives you a precise character count for any text, with real-time updating as you type. Toggle between counting with or without spaces, and check your text against common platform character limits: Twitter/X (280), SMS (160), Instagram bio (150), meta descriptions (155–160), and Google Ads headlines (30). Whether you're crafting the perfect tweet, writing SEO metadata, composing an SMS campaign, or filling out a form with a character limit, this tool ensures you stay within bounds.
The Password Generator creates cryptographically secure, random passwords tailored to your requirements. Choose password length (8–64 characters), and include or exclude uppercase letters, lowercase letters, numbers, and special characters. All generation happens entirely in your browser using the Web Crypto API — your passwords are never sent to any server, never logged, and never stored. Use the copy button to copy instantly. For maximum security, pair generated passwords with a reputable password manager rather than memorizing them or writing them down.
The Word Counter instantly analyzes any text and gives you word count, character count (with and without spaces), sentence count, paragraph count, and estimated reading time. Paste or type your text and get results in real time as you write. Essential for blog posts with minimum word count requirements, college essays with strict word limits, SEO content that needs to hit 1,500–2,000 words, social media posts with character caps, and any writing task where length matters. Results update live — no submit button needed.
