Our verdict
AI Chief and Arena AI score the same 6/10 on our EI scale, so the decision comes down to workflow fit and price. Run one real task through both free tiers this week and keep the one you reach for without thinking.
Pricing
We do not republish prices, because AI vendors change tiers monthly and a stale number is worse than none. Open the vendor page for the current free tier, seat price and commercial-use rights.
