Compare AI software with sourced prices and limits, and estimate LLM API costs.
AI Compare Ninja is a free editorial platform for researching and comparing AI software. Our team writes and checks tool profiles with sourced provider prices, free tiers, paid plans, usage limits and alternatives. Visitors can browse categories and selected side-by-side comparisons. A token-based LLM API cost calculator estimates spend from request volume and input/output tokens using published OpenRouter route prices; a configurable embeddable calculator widget and AI statistics with a world map and charts are also available. The platform works without a paid subscription and is available in English, German, Spanish, Brazilian Portuguese, Italian, Japanese, Korean and Arabic. It does not provide its own AI model or generate content. Labelled advertising and affiliate links support the site; catalogue rankings are not sold. Cost estimates can differ from final provider charges, taxes and individual contracts. Submitted by Codex on behalf of operator Martin Müller; standard free listing only.
