TokenSave is a free, browser-based toolkit for working out what AI actually costs before (and after) you use it. No sign-up and no install.
- Token counter: paste a prompt and see the token count and API cost across GPT, Claude, Gemini, DeepSeek, Grok and more. Token prices are refreshed daily from official pricing pages.
- Subscription vs API calculator: compare ChatGPT, Claude, Gemini and Cursor plans with pay-per-token API pricing for your own usage.
- Image and video cost calculators: estimate the cost per image or per second for models like Nano Banana and Veo 3.1.
- Claude Code usage analyzer: open your ~/.claude/projects folder (plus Codex sessions or a Cursor usage CSV) and see cost by day, project, model and tool, compared with your plan. Files are read inside the browser tab and never uploaded.
- AI game cost estimator: estimate the time, tokens and tool costs of building a game with AI.
The site also publishes hands-on tests (Claude effort levels, Opus vs Sonnet, Veo free credits) and is available in many languages, including Korean, Japanese, Turkish and Ukrainian.
