What our research says

Midjourney

Midjourney still produces the most immediately attractive images of any generator, and it is still the least programmable. Buy it if you are art-directing by eye; look elsewhere if a machine has to call it.

Pros

  • Default aesthetic quality is still the reason people pay for it
  • Style and character references keep a look consistent across a set
  • Image-to-video arrived natively rather than through a bolted-on partner

Cons

  • No official public API, and unofficial wrappers breach the terms of service
  • GPU-hour metering makes cost per image hard to predict, and video burns roughly 26x a still
  • Images are public by default until you reach the $60 Pro tier
  • No free trial since 2023, so evaluation costs $10

SeiSei AI

SeiSei AI's guest mode, three free images a day with no account, is a genuinely low-friction way to test quality before committing, and letting you pick the underlying model per job gives some control over cost versus quality. Beyond the free daily allowance, the mix of subscriptions and separate one-time credit packs makes the pricing a bit more to parse than a single flat plan.

Pros

  • Three free images a day with no account required
  • Choice of underlying model with price shown before generating
  • Both subscription and one-time credit-pack options exist
  • Annual billing cuts the price by roughly 40%

Cons

  • No company or location information disclosed
  • Per-model pricing means cost is not fully predictable until you pick a model
  • Entry subscription is $19/month, higher than some single-purpose image generators

Which one fits

Choose Midjourney if you need

  • Concept art, mood boards and editorial illustration where look beats control
  • Designers iterating visually rather than specifying precisely
  • Client work, provided you are on Pro or above for stealth mode

Choose SeiSei AI if you need

  • Testing product or ad concept images without creating an account first
  • Users who want to choose a cheaper or pricier model depending on the job
  • Occasional users who would rather buy a one-time credit pack than subscribe
