See what every AI prompt is about to cost you.

Token Wise auto-detects ChatGPT, Claude, Perplexity, Gemini, and Grok, shows a live token-cost estimate next to the prompt box, and rewrites your prompt to be cheaper and clearer in one click. No setup, no API key required.

Everything you need to spend less on AI

Live cost estimate

Token count and credit estimate next to the prompt box as you type, color-coded by spend.

One-click optimize

Cloud rewriter trims fluff and tightens intent. Pick Balanced, Shorter, Clearer, or More specific.

Side-by-side savings

Original vs optimized with token and credit diffs, plus copy and use-this-prompt actions.

Dashboard & history

Today, 7-day, and total-saved stats. A 100-prompt history page with CSV export.

Transparent pricing

Every estimate uses the model's own published per-token rate — see the math on the How it works page.

Keyboard-first

Alt + Shift + O optimizes the current prompt without leaving the keyboard.

Privacy by default

Prompts never leave the browser unless you click Optimize. A local-only mode keeps everything offline.
