What our research says

Ideogram

If the image needs words in it, this is still the model that spells them correctly, and that single capability is worth more than a broader feature list to anyone making posters or packaging — everything else about it is merely competitive.

Pros

  • Text rendering remains the best in the category and is the whole reason to choose it
  • Documented API at docs.ideogram.ai for integration
  • Style presets, region editing and character consistency round it out beyond a bare generator
  • Entry tier at about $8 is cheap next to Midjourney

Cons

  • Credit costs vary by model and quality setting, so plan sizes are hard to translate into images
  • Free tier is a weekly trickle rather than anything usable
  • The pricing page is bot-protected, making prices hard to confirm independently
  • Priority credits are monthly and the queue is genuinely slow without them

Logo Diffusion

The best of the AI logo generators if you can already art-direct, because sketch-to-logo plus real SVG export puts it ahead of the template mills. If you want a finished identity handed to you, hire a designer; this gives you raw marks you still have to curate.

Pros

  • Sketch and image inputs give far more control than prompt-only generators
  • True vector SVG export rather than an upscaled raster
  • Vectoriser, upscaler and mockups bundled, removing a round trip to other apps
  • The $15 one-time pack lets you finish one logo without subscribing

Cons

  • Credits expire monthly, so unused allowance is money lost
  • The free tier's 24 credits is roughly a dozen generations, enough to evaluate but not to finish
  • Commercial licence on the cheap Starter Pack covers only a single logo
  • No API and no team or brand-kit management
