Tools for evaluating AI.
Free tools we built — and use ourselves — for AI cost evaluation, vendor comparison, capability research, and team planning. Updated weekly. Designed for builders, buyers, and the procurement teams in between.
Cost & Comparison
Pricing data, cost estimation, and side-by-side vendor comparison. Built so AI buyers — from solo developers to enterprise procurement — can make decisions with real numbers, not vendor pitches.
LLM Cost Calculator
Compare cost, intelligence, speed, and latency across 100 leading LLMs.
AI Subscriptions
Every direct-to-consumer AI plan in one place — Claude Pro, ChatGPT Plus, Gemini Advanced, and more.
Team Usage Calculator
Estimate monthly LLM costs across employees, workflows, and providers — with real cost breakdowns.
Directories & Leaderboards
Curated reference resources — directories of AI capabilities and modality-specific leaderboards. The places to go when you need to know what exists and what's best.
MCP Directory
A curated directory of Model Context Protocol servers — every MCP an AI builder might integrate.
Claude Skills Library
Curated capabilities that extend Claude for specific workflows — official Anthropic skills + community submissions.
AI Model Leaderboards
Top 10 AI models for each modality — image, video, speech, music — ranked by performance benchmarks.
