TokenSave - Count AI tokens and cut them up to 50% with one click

by•
Non-English prompts cost more: the same text in Korean, Japanese or Greek can use 1.4–2× the tokens of English. TokenSave counts tokens and cost for GPT, Claude and Gemini, then translates your prompt to English in the browser and adds "Reply in ", so you get the same answer for fewer tokens. Code stays untouched; only comments are translated. Also compares ChatGPT, Claude and Gemini plans with the API. 41 languages, no sign-up, nothing uploaded.

Hi Product Hunt 👋 I'm a solo developer from Korea. I write most of my prompts in Korean, and I noticed my usage limits ran out faster than my English-speaking friends'. It turns out the same prompt in Korean takes about 1.4× the tokens, Japanese about 1.8×, and some languages over 2×. So I built TokenSave: • Paste a prompt and see tokens and cost for GPT, Claude and Gemini • One click translates it to English (on your device) and adds a line so the AI still answers in your language • Code blocks are left alone, only comments get translated • A calculator that tells you whether a subscription or the API is cheaper for how you actually use it Everything runs in your browser. No account, and your text never leaves your device. I'd love to hear which language you prompt in and how much it saved you. Feedback and feature ideas are very welcome!
