Stop guessing which AI tools are good. Agentix grades any agent or tool S-F in seconds — then tracks momentum so you know who's rising and who's slipping. Search an agent, get an instant score broken down across 5 pillars, and watch its grade momentum rise or fall over time. WHAT YOU CAN DO • Grade any AI agent or tool and get a single S–F letter grade in seconds • See the score broken down by pillar — acceleration, traction, app & team credibility, and niche position — each with a plain-English rationale • Compare an agent head-to-head against the top 2 rivals in its space • Build a watchlist and track each agent's momentum (up or down) as it improves or slips • Call an agent's trajectory in play-money paper mode — go long or short and follow your P&L (no real money, ever) WHY AGENTIX Every other AI directory just lists thousands of tools and leaves you to guess. Agentix grades them. The score is forward-looking, transparent, and hard to fake — built to tell you not just what an agent is, but whether it is getting better or worse. WHO IT IS FOR Builders, investors, and curious users who want to evaluate AI agents before they trust them — and keep tracking the ones that matter. Agentix is free — no account, no sign-up. Grade as many agents as you like and keep your full history. Built by Jason Colapietro, founder of Suede Labs — building ownership infrastructure for the AI era. Grades are informational and are not financial advice. Paper mode uses play money only.
