Toolbench puts 194 everyday tools in one fast, keyboard-friendly workbench: search with /, open with Enter, pin favorites to number keys and send any output straight into another tool.
Nearly every tool is plain JavaScript running in your browser. Text you paste, images you drop and numbers you enter are processed locally, not on a server. Nothing is saved unless you sign in — then your settings, history, pastes and images sync privately to your account. Where a tool genuinely needs the network — AI generation, IP lookups, YouTube thumbnails — the page says so, and exactly where the request goes.
The AI SEO and AEO tools call OpenAI, Anthropic or Google directly from your browser with your own API key. There’s no middleman server and no markup, and your keys are never stored by us.
