Relevant I Love Free category: Coding & Development

Details:

GhostInterview is built for live technical interviews on macOS and Windows. The desktop overlay is designed to stay invisible during screen sharing while giving candidates real-time support for LeetCode-style coding, system design, object-oriented design, debugging, project deep dives, behavioral rounds, and tough follow-up questions from interviewers.

The product focuses on programmer interview workflows: understanding the live prompt, reasoning through the answer, keeping context from the ongoing interview, and helping candidates respond naturally when the interviewer changes direction or asks deeper follow-ups.

GhostInterview is not just a coding-answer generator. It is made for the full technical interview loop, including interpreting screen and voice context, structuring the answer, explaining tradeoffs, and adapting to follow-up questions while the interview is still moving.

CoffeeTrans: 一键式为音视频生成 Netflix 级别的精准时间轴字幕
大家好，很高兴在这里向各位介绍我的新产品 CoffeeTrans。这是一款针对音频或者视频的上传、字幕识别、翻译、导出的一键式转录翻译平台

网址： https://coffeetrans.app

为什么开发 CoffeeTrans ？

我的大学专业是计算机，接触过很多国外高质量课程，社区贡献了很多高质量的课程翻译，但是更多的课程没有人搬运，我自己英语还做不到流畅的正常速度观看吸收，因此想做一个自己的翻译工具

我知道社区有一些开源的实现，我自己也跑过，老实说对于普通人来说存在一些问题：安装有门槛容易包错、需要比较好的机器性能才能跑比较大的 Whisper 模型，转录速度比不够快、翻译经常抽风，跑到一半直接断了、字幕烧录非常的吃机器性能，一套流程下来耗时挺长的，当然如果是偶尔使用还是可以接受的

又有很多人会说了，这不就调用一下转录模型和大模型进行翻译吗？是的，这个承认，但是多少产品不是这样呢，一个功能到一个产品是有很多坑要踩的

另外就是国外也有很多类似的平台，不过很多聚焦于全视频处理平台，转录和翻译是其中的一小部分，额度很小并且比较贵，对于专门做转录和翻译的选择会更少

最后，因为自己也想搓一个就做了

为什么取名叫 CoffeeTrans ？

我希望泡杯咖啡的时间就能完成高质量的翻译过程，所以就叫 CoffeeTrans 了

核心特点

• 快速翻译：相比本地 Whisper 转录，使用 CoffeeTrans 的转录更快，2小时的视频可以在几分钟内转录完成

• 批量处理：可以上传多个文件同时转录翻译

• 多语言支持：这应该是转录翻译的基本功能

• 高质量翻译：基于最新的大语言模型，翻译质量有保障。

• 上下文感知：在翻译之前会整体扫描一遍上下文，自动提取术语、关系等，后续翻译都会携带上下文，保证翻译的连续性和准确性

• 多格式支持：支持常见的音视频格式

• 精准时间轴：生成的字幕时间轴非常准确，对于需要处理字幕的人来说非常有用

• 字幕导出：支持导出为 srt 方便二次修改

• 支持一次翻译为多种语言：可以一次性选择翻译为多种目标语言，极大的减少工作量，节省 credits

• 智能去除语气词：智能去除语气词，让字幕更加自然流畅

技术选型

• 转录：使用了云服务商提供的 API

• 翻译：使用大模型做上下文提取 + 翻译

• 存储：Cloudflare R2

• 字幕烧录：Modal 动态创建 worker

应用场景

• 学生：学习国外优质课程

• 独立开发：发布自己的多语言版本介绍

• 法律/金融/医疗专业人士：高效翻译专业领域的视频观看

• 内容创作者：将自己的课程发布到全球，获取全球观众

• …

免费用户有 30 积分的额度（相当于 30 分钟的转录或者 30分钟的翻译，一分钟的转录或者翻译消耗 1 个积分）

Hi everyone,

I recently built Image to Music AI, a simple AI tool that turns an image into matching music.

The idea is straightforward:

1. Upload an image

2. Let AI understand the mood, scene, and visual style

3. Generate a piece of music that fits the image

It can be useful for short videos, social media posts, game scenes, product visuals, mood boards, or anyone who wants background music inspired by an image.

For example, you can upload images like:

– a cyberpunk rainy street

– a sunset beach photo

– a fantasy game scene

– a retro record store

– a cozy forest cabin

– a cinematic poster

Then the tool generates music based on the visual atmosphere.

The product offers free credits for new users, so you can try it without paying first.
