What AI tools really cost per minute, image and word
Plans are sold in credits, tokens and "generations", which makes them hard to compare. We converted 12 tools' plans into the thing you actually get: a minute, an image, 1,000 words. Only at the rate each vendor publishes; where a page doesn't say, the tool isn't here.

How we calculate
For each paid plan we take the monthly price (billed monthly where the vendor offers it) and the allowance the pricing page states, and divide. The table shows each tool's cheapest plan per unit. Credits are converted only with the vendor's own rate (for example credits per minute), and every allowance is matched to the vendor's wording. Higher tiers often add features rather than cheaper units, so the cheapest per unit isn't always the cheapest plan. Unlimited plans are left out because they have no per-unit cost.
