The notebook calculator that thinks for you (now with AI).
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!"
