Hunted bySiddarth KengadaranSiddarth Kengadaran

Most calculators give you answers but lose the context. CalPal is a literate calculator that combines a text editor with a calculation engine, letting your math tell a story. The standout feature is the BYOK AI Assistant (Gemini). It solves "Blank Page Syndrome"—just ask it to "Draft a travel budget" or "Estimate MVP costs," and it generates the line items instantly for you to tweak. It's 100% free, private (local-only data), and browser-based.

"Hi Product Hunt! 👋 I’m Siddarth, the maker behind CalPal. I built this because I have a "Blank Page" problem. Whenever I try to plan a project or budget, I get stuck between a dumb calculator (no context) and a complex spreadsheet (too much friction). CalPal is a literate calculator. You type notes, and it does the math inline. What makes it different? It has a built-in BYOK (Bring Your Own Key) AI Assistant powered by Gemini. Stuck on a budget? Just ask: "Draft a launch plan for a SaaS app." The AI writes the line items; the calculator tallies the cost. It’s free, private, and runs in your browser. I’d love to hear what you think!"

Comment highlights

@siddarth_kengadaran Brilliant solution to Blank Page Syndrome! The thought-to-execution model uniquely positioned between Excel's complexity and calculators' context loss. Timezone coordination, unit conversions, date arithmetic, and Gemini integration create a genuinely novel workflow for distributed teams handling budgets and planning. Asking "Plan a trip to Paris" naturally closes exploratory math. This is the missing piece between static sheets and dumb calculators.
