Facts from each product's IndieNeed listing, side by side.
JustCalculators.app provides more than 290+ free online calculators across six major categories: financial, health & fitness, math, utility, crypto/DeFi, and eCommerce. Every tool delivers instant, accurate results directly in your browser — no registration, no subscription, no downloads required, and your inputs never leave your device.
Six free learning assistants for game theory, data science, reinforcement learning, linear algebra, the web platform and Golden Age inquiry. They run entirely in your browser: retrieval plus BM25 search and a 13,079-parameter policy compiled to WebAssembly, with an optional 22 MB MiniLM model, instead of a large language model. Worked answers show the math.
