Common questions

Can I use DiffusionBee on my phone?

No, DiffusionBee only works on macOS computers. If you need to generate AI images on your phone, use SeaArt.AI in your mobile browser.

Is SeaArt.AI really free?

SeaArt.AI's pricing is not clearly published, so it may offer free credits or a trial, but heavy use could cost money. DiffusionBee is genuinely free forever with no limits.

Which tool is better for a beginner who has never used AI art?

SeaArt.AI is easier for absolute beginners — just type and click. DiffusionBee requires a one-time download and model setup, but is still very beginner-friendly for Mac users.

Can I edit or fix parts of an image after generating it?

DiffusionBee supports inpainting (editing specific areas) and outpainting (extending the canvas). SeaArt.AI lacks these advanced editing features.

Will DiffusionBee slow down my Mac?

It can be resource-heavy, especially on Macs with only 8GB RAM. You may notice your computer getting warm or slowing down during generation. SeaArt.AI runs in the cloud, so it won't affect your device's performance.

DiffusionBee is the free, private, Mac-only powerhouse; SeaArt.AI is the easy, cross-platform browser tool with unclear costs.

If you have a Mac and care about privacy or unlimited free use, go with DiffusionBee. For everyone else — especially if you use a phone or Windows — SeaArt.AI is the simpler, faster choice. Just keep an eye on its unclear pricing if you plan to generate a lot.
