How we ranked these
We ranked tools by how directly their own pages show concept-art workflow features such as sketch and reference input, style control and editing, then by stated commercial-use terms and cost to start, using official feature, pricing and licence pages. Ideogram and Recraft were left out because we did not read pages showing a concept-art workflow, and several vendors did not publish prices or commercial terms on the pages we read; we say so rather than guess. Leonardo.Ai and Midjourney prices were read from each vendor’s pricing page; billing terms for Leonardo.Ai and Krea are not fully explained there. This is a general guide, not legal advice on image rights. Facts are taken from each maker's own published information; check the official site before you buy.
