I'm Thibaud, and I'm excited to share the Context Budget Planner. The Problem LLM API bills can be hard to anticipate and most token calculators only support OpenAI, and none let you compare costs across providers. The Solution Context Budget Planner lets you: - 📊 Calculate token counts for Claude, GPT-4, Gemini, and more - 💰 Estimate costs (input + expected output) before sending - ⚖️ Compare models side-by-side to find the cheapest option - 🔒 Keep your data private with 100% client-side processing Why Privacy Matters Your code, documents, and prompts never leave your browser. Everything runs locally using WebAssembly. No servers, no tracking, no data collection. Tech Stack Built with Next.js 16, TypeScript, and tiktoken. It's a static export—zero server-side processing. What's Next? - Pro tier coming in Q1 2026 (unlimited templates, batch processing, cost tracking) - [Join the waitlist](https://docs.google.com/forms/d/...) for early access Try it out and let me know what you think! Happy to answer any questions. 🔗 https://contextbudget.vercel.app
