About

Why this exists

Many online tools demand an upload, an account, or bury a simple operation under ads. This site does the opposite: everything runs in the browser — no sign-up, no upload, no watermark.

The prompt side aims to save you from dead ends: each entry states when it fits, when it does not, and how it is commonly misused.

Scale

150 tools, 150 usage guides, 24 multi-step workflows and 5020 prompts across Chinese, English and Japanese.

Of the prompts, 120 are written by us, 2920 come from open-source projects (source and licence labelled on each page), and 1980 are original.

Under the hood

Everything is static HTML. The build scripts have zero third-party dependencies and the server runs nothing but nginx. Tools use native browser APIs — no cloud model is called.
