AI Token & Cost Tracker

Stop wondering what that ChatGPT conversation just cost you. AI Token & Cost Tracker sits quietly in your browser and shows you, in real time, exactly how many tokens you're using and what they cost — for every message, every conversation, every day. No copy-pasting into a tokenizer playground. No spreadsheets. No surprises on your usage bill. ⚡ Live, per-conversation tracking A floating badge (which you can drag anywhere or hide entirely) updates as responses stream in, showing your running token count and cost estimate without ever leaving the chat. 💰 Real dollar costs, not guesses Costs are calculated from each model's actual per-token pricing — GPT-4o, GPT-4.1, GPT-5 and beyond, including o-series reasoning models. Switch models mid-conversation and the tracker follows along automatically. 📊 Context window awareness A live context bar shows how close a conversation is to its model's limit, turning amber and then red as you approach it — so you're never blindsided by dropped context. 📅 7-day usage history Open the popup for a full breakdown: today's conversation, and a 7-day chart of total tokens and spend so you can spot your heaviest days at a glance. 🔔 Daily token budgets Set a soft daily limit and keep an eye on cumulative usage across all your conversations, not just the one you're in. 🌓 Light & dark themes Matches your system theme automatically, or pin it manually — the popup and the on-page badge both adapt instantly. 🔒 100% local, 100% private Everything is calculated and stored on your own device with chrome.storage — nothing is ever sent to an external server. Your conversations and usage data never leave your browser. Currently supports: ChatGPT (chatgpt.com / chat.openai.com), with accurate pricing for the full GPT-6 Astra, GPT-4o, GPT-4.1, GPT-5 and o-series (o1/o3/o4) model lineup. Install it once, forget it's there, and let it quietly keep track of what your AI usage actually costs.
