-`narrator-ai-web` is a self-hostable Next.js frontend for template-driven commentary-video task creation. It provides the user interface and a thin BFF (Backend-for-Frontend) layer for uploading material, selecting templates, creating tasks, and viewing task progress.
+`narrator-ai-web` is a self-hostable Next.js frontend for NarratorAI, a template-driven workflow that helps users turn movies, short dramas, raw clips, and other long-form video material into commentary videos.
+
+Users upload source videos or import video URLs, choose a commentary template, review the task price, and submit the job. The connected backend can generate commentary scripts, editing instructions, and a condensed commentary video suitable for publishing on short-video platforms.
+
+Each commentary template can carry its own price. Before a task is submitted, the frontend asks the backend for a quote so the user can confirm the charge first.
+
+This project is useful for movie commentary, short-drama commentary, plot recaps, content-studio batch production, and teams that want to package commentary templates as sellable products.
 
 The repository does not include model inference, video generation, wallet, or orchestration services. Those capabilities are expected to run in a compatible backend service that exposes the APIs configured through environment variables.

-`narrator-ai-web` 是一个可自托管的 Next.js 前端，用于模板化解说视频任务创建。它提供用户界面和一层轻量 BFF（Backend-for-Frontend，前端专用后端）能力，支持上传素材、选择模板、创建任务和查看任务进度。
+`narrator-ai-web` 是 NarratorAI 的可自托管 Next.js 前端，用于模板化视频解说制作。它可以帮助用户自动完成电影、短剧等视频的解说制作。
+
+用户上传原始视频、影视片段、短剧素材或其他长视频素材后，选择一个解说模板，系统会通过连接的后端根据模板生成解说文案、剪辑脚本，并合成一条适合短视频平台发布的精简版解说视频。
+
+每个模板都可以配置自己的价格。用户在提交任务前可以看到本次任务价格，确认后再提交生成。
+
+这个项目适合用于电影解说、短剧解说、剧情混剪、内容工作室批量交付，以及想把解说模板做成可售卖商品的团队。
 
 本仓库不包含模型推理、视频生成、钱包或任务编排服务。这些能力需要由兼容后端服务提供，并通过环境变量接入。
