分享我刚上线的一个项目: On Brand Ads,粘网址生成品牌广告 最近上线了一个自己做的项目,来 V2EX 分享一下,求各位拍砖。 地址: https://onbrandads.com 做这个的起因:自己在做项目需要投广告时发现,市面上的 AI 广告生成工具基本两种—— 要么给你一个空白 prompt 让你自己写,要么就是把一张图裁成几个尺寸。 品牌对不上,文案更没人帮你写。 所以这个项目反过来做,核心思路是「文案优先」: 1. 粘网站 URL ,自动抓取真实的品牌信息(颜色、字体、Logo 、标题、产品卖点), 每条都标注来源,不编造。 2. 先生成文案:选广告目标(被人认识 / 讲清价值 / 促成下单 / 建立信任), 自动起草标题和 CTA 。 3. 一次出 5 种尺寸:1:1 / 4:5 / 9:16 / 16:9 / 21:9 ,每个尺寸原生构图,不是裁剪。 商业模式是积分制,1 积分 = 1 张图,注册送 6 个积分,不用绑卡。 技术栈: - Next.j
