Claude-optimization tools in a side panel — count tokens, audit prompts, compare model costs — right alongside claude.ai. A side panel for builders working with the Claude API. Open it next to claude.ai (or any tab) and run the TurnTwo Workbench tools without leaving the page: • Count tokens in any text (≈ within 10% of Claude's tokenizer) • Audit a prompt for the most common cost mistakes — and what fixing them saves • Find wasteful phrasing (hedges, filler, wordiness) with leaner replacements • Compare what a call would cost across Claude, GPT, and Gemini It's free, needs no account and no API key, and the tools run on TurnTwo's servers — the extension only sends the text you type into the panel. For generative work (rewriting, drafting) use Claude itself; this panel is for the exact numbers Claude can't compute on its own. Part of the TurnTwo Workbench: https://turntwo.dev/use
