AI Toolkit (slashmantools.us) is an independent, one-person project that builds and maintains a growing collection of free, fast, privacy-friendly online tools. Everything is free to use, needs no sign-up, and most tools run entirely in your browser — the data you enter never leaves your device.
Most online utilities are cluttered with pop-ups, demand uploads, or hide features behind sign-ups. The goal here is the opposite: clean, single-purpose tools that load instantly, work on mobile, support multiple languages, and respect your privacy by doing the work locally whenever possible.
The tools are hand-built static web apps. Where a tool processes your input (text, files, images), that processing happens client-side in your browser. The finance dashboards are generated from public market data and refreshed automatically.
The site is kept free with the help of advertising and affiliate links (see our Privacy Policy). If a tool saved you time, you can also buy me a coffee on Ko-fi — thank you!
Feedback, bug reports, or suggestions for new tools are very welcome: get in touch or email ytstories0413@gmail.com.
