I built a tool that scores your video's opening line before you film it. Looking for 5 creators to try it

I'm a solo founder. Contextify started from one problem: short-form creators only find out their opening was weak after they post, when it's too late to fix. What it does: you paste your hook or script, or upload the video. It scores the words on hook strength, clarity, pacing, rewatch value, and search, points to the exact line losing attention, and suggests a stronger version you can say in one take. It judges the words, not the visuals, and it doesn't predict views. See a real resu

AI 分析

痛点:短视频创作者只有在发布后才知道开场钩子(hook)太弱,此时已无法补救,缺少开拍前的可量化校验工具。

目标用户:TikTok/Reels/Shorts 等短视频的独立创作者与小型代运营团队,尤其是自己写脚本的 solo creator。

证据:short-form creators only find out their opening was weak after they post, when it's too late to fix. / free hook check, no signup ... (score and diagnosis are free; rewrites are part of the paid plan). / I'm looking for 5 creators filming something this week. You get 14 days of Plus free, no card

变现:免费评分+诊断引流,付费订阅(Plus)解锁钩子改写、脚本优化与批量分析;后续可做团队版、API 嵌入剪辑工具、按次付费的 hook 重写包。

MVP:两周内可做:上传/粘贴脚本 → LLM 按 hook 强度、清晰度、节奏、复看价值、搜索性五维打分 → 高亮最弱那句 → 给出 3 条可一次性口播的改写版本。免费出分,改写放在付费墙后,用 Stripe 订阅 + 每日次数限制即可上线。

竞品:ChatGPT/Claude 直接写 hook、Opus Clip、Submagic、VidIQ / TubeBuddy 的标题与脚本建议、Predis.ai、各类 TikTok hook generator 小工具

摘要:一位独立开发者推出 Contextify,可在拍摄前给短视频开场白打分,维度包括钩子强度、清晰度、节奏、复看价值和搜索性,并指出最拖后腿的那一句,给出可直接口播的改写版本。评分与诊断免费、改写属于付费计划,作者正在招募 5 名本周要拍摄的创作者免费试用 14 天 Plus。帖子里没有任何真实付费用户或收入数据,需求仍属创始人自述,且同类 AI 脚本/钩子工具竞争密集。
