What is K-K?

K-K offers free web tools, minigames, and AI business system consulting. We run URL shortener, QR code generator, calculators, timers, password generator, image resizer, 2048, Tetris, Snake, and more—all in the browser with no install. We also provide AI-era workflow refactoring diagnosis and design for businesses and teams.

Why did we build this site?

We wanted one place for everyday tools (unit conversion, word count, QR codes, etc.) and light games, free to use. We add clear descriptions and tips on tool and game pages so content is genuinely useful, not clickbait. The site is run by an AI/IT team; ad revenue supports maintenance and improvement.

What we offer

• Tools: URL shortener, QR generator, salary/loan/discount calculators, password/hash generator, Base64/JSON converter, word counter, stopwatch, Pomodoro, image resizer, color picker, and more.
• Games: 2048, Tetris, Flappy Bird, Dino Run, Snake, Minesweeper, Memory, Reaction, Wordle, Sudoku, typing practice, and more (some with leaderboards).
• Services: AI workflow diagnosis and refactoring design, IT development inquiries (contact form on the landing page).

Privacy & ads

How we maintain content

We keep expanding usage notes, limitations, and FAQs on tool and game pages. We avoid thin pages that only list links and aim for clear, human-written guidance that actually helps visitors complete a task.

Quality and originality

Explanations are written and edited in Korean, English, and Japanese by our team. AI-assisted products (e.g. Daily Brief) include sources. Please tell us if you spot errors or outdated information.
