AI Image Generator From Text Free Online 对比 Prexi

AI Image Generator From Text Free Online is a browser-based image generation site that turns written prompts into finished artwork. You type a description, pick one of four model presets, choose output dimensions, and download the result in seconds. The homepage runs without an account, which makes it a quick option when you need a visual draft rather than a full design suite.

Where many image tools bury model choice behind settings panels, aiimagegenerator.is puts Normal, Realistic, Anime, and 3D Anime on the main workflow. The site also advertises an image-to-image mode that keeps the structure of an uploaded file while applying your text edits. Stable Diffusion XL sits at the center of the stack, so the trade-off is speed and simplicity over deep inpainting or layer control.

The site targets hobbyists, bloggers, marketers, and indie designers who want stock-style visuals without opening Photoshop. FAQ copy states that regular users face a daily generation cap while premium accounts get higher or unlimited access, and that commercial use is permitted. If you need predictable billing or team seats, the missing public pricing page is the main gap.

Prexi 是一个由三人团体在里斯本精选的提示词库，收录了 3,400+ 个经过测试的图像提示词。您可以浏览 Liminal Spaces 或 Tokyo Nights 等合集，复制为 Flux 1.1 Pro、Midjourney v7、Nano Banana Pro、SD3.5、Seedance 及 Veo 优化的提示词，并在不离开标签页的情况下重新混合变体。浏览与复制始终免费，而 Studio 套餐每月 9 美元则可解锁更高的生成限制。

大多数提示词列表均从论坛爬取，并在模型更新后迅速过时。Prexi 会在 Flux、Midjourney 或 Nano Banana 发布新版本时亲自重新测试批次，这对需要仍能清晰渲染的提示词至关重要。代价是其专注于图像提示词，而非通用聊天模板或视频脚本。

设计总监、创意技术专家及音乐视频导演使用 Prexi 来制作氛围板、将特定模型的提示词粘贴到 fal.ai 或 Discord，并分享合集链接以替代 Pinterest 画板。免费账户每天可生成 1 次预览；Studio 套餐将每日预览生成次数提升至 100 次。
