GPT Image 2.0 Prompt - Emblème technologique premium Univer

You are designing the master brand mark for a premium technology ecosystem named "Univer". This is not a playful startup logo. This is a serious, long-term, world-class brand symbol meant to represent a platform for intelligence, context, memory, files, workflows, and trusted AI experiences. Brand essence: - universal - intelligent - structured - calm - powerful - precise - trustworthy - modern - enduring - premium The logo must feel like a symbol that could sit comfortably beside the branding of Apple, OpenAI, Stripe, Anthropic, Linear, Notion, or Arc, while remaining entirely original and unmistakably Univer. Design objective: Create a single iconic abstract mark with a subtle connection to the letter "U", but it must NOT be a literal U. The mark should feel like a gateway, aperture, frame, or portal into a larger intelligent system. It should imply entry, access, structure, and depth. Core design principles: - one unified symbol, not multiple shapes - bold, stable silhouette - strong negative space - minimal geometry - excellent optical balance - architectural proportion - premium restraint - memorable from a distance - clear and legible at tiny sizes - capable of functioning as an app icon, favicon, embossed hardware mark, product badge, and brand stamp Visual direction: - geometric, not organic - minimal, not decorative - confident, not flashy - timeless, not trendy - futuristic, but not cliché futuristic - elegant, but not luxurious in a fashion-brand way - strong, but not aggressive - simple, but not generic The symbol should evoke: - a doorway into knowledge - a controlled opening - a structured portal - a contained universe - a trusted environment - a system that organizes complexity Important constraints: - do NOT create a literal uppercase U - do NOT use obvious AI clichés: brain, circuit, neuron, atom, globe, star, sparkle, chatbot bubble, robot face, AI swirl, hexagon network, or generic tech mark - do NOT make it look like a random abstract art piece - do NOT make it too complex - do NOT use thin lines or fragile details - do NOT use gradients, shadows, bevels, 3D effects, or glossy rendering - do NOT make it look like a temporary startup logo - do NOT make it look like a gaming logo or a crypto logo - do NOT use a lowercase or uppercase text logo as the main symbol Form language: - strong outer mass - controlled inner cut or aperture - high-quality negative space - subtle internal symmetry - possible hidden suggestion of U through shape or void, but only as a discovery, never as an obvious literal form Brand behavior: This symbol should look equally strong: - in black on white - in white on black - as a standalone icon - when embossed or engraved - when reduced to 16x16 px - when printed on product surfaces - when used across the full family: Univer, Apex, Normal, Swift Typography note: The logo mark should be able to live independently. Wordmark is optional and secondary. The symbol must carry the identity on its own. Design tone: - premium enterprise - calm authority - deep intelligence - highly refined simplicity - emotionally restrained - confident and enduring Output expectations: Provide a distinctive, polished, brand-ready master mark that feels inevitable, as if it has always belonged to Univer.
