# Toolbench

> Toolbench is a free workbench of 194 online tools — word counter, JSON formatter, image resizer, binary converters, calculators, AI SEO generators and more. No installs, and most tools run entirely in your browser.

Toolbench runs almost entirely client-side: text, code, images and numbers are processed in the visitor's browser, not on a server. Signed-out visitors have nothing saved; signed-in users' settings, history, pastes and images sync privately to their account. AI tools call OpenAI, Anthropic or Google directly with the user's own API key. Every tool is free; no account is needed except a free Google sign-in for AI tools and saving pastes/images.
