ArcadeOn Pixel and ArcadeOn Sprite are native Windows applications that work locally without login, cloud or web upload. Users retain ownership of AI generations and can use downloaded output commercially worldwide without royalties, revenue share or a unit cap. Free provides 15 credits after email verification and 8 free daily credits. One-time packs start at £1, paid once; monthly options include Indie at £4.50 a month and Studio at £11.25 a month.
