Free AI prompt compressor for ChatGPT, Claude, Gemini, Perplexity and more. Cut tokens, save money, see the CO2 behind every prompt. TerraWatch is a free AI prompt compressor. It shrinks the prompts you write in ChatGPT, Claude and other AI chat tools, so you use fewer tokens, hit usage limits later, and still get the answer you asked for. Every prompt has a price. TerraWatch shows what it costs in tokens, energy, CO2 and water, then helps you cut it in one click. HOW IT WORKS Write your prompt like normal. TerraWatch appears in the corner with a live token count and environmental impact. Click Optimize. A highlighted preview shows exactly what can go: filler words, wordy phrases, unnecessary politeness and repeated instructions. Nothing changes until you choose. Quick Clean applies it instantly. Free, unlimited, no account, and it runs entirely in your browser. Code you paste is left untouched. Deep AI Rewrite goes further, restructuring the prompt with AI while keeping every requirement. 3 free a day with no account, 10 a day with a free account.
