Hook: The Power of Solving a Real Problem
钩子：解决实际问题的力量

As developers, we all know the frustration of trying to find reliable answers to our coding questions. While tools like ChatGPT can be helpful, they often generate code with errors or hallucinations. This is the problem I set out to solve with my startup, Devv (https://devv.ai) - an AI-powered search engine built specifically for developers.
作为开发人员，我们都知道试图为我们的编码问题找到可靠答案的挫败感。虽然像 ChatGPT 这样的工具可能会有所帮助，但它们通常会生成带有错误或幻觉的代码。这就是我的创业公司Devv（https://devv.ai）要解决的问题，Devv是一个专门为开发人员构建的人工智能搜索引擎。

Understanding the User: 50 Developer Interviews
了解用户：50 次开发人员访谈

Before writing a single line of code, I wanted to deeply understand the needs and pain points of our target users. I conducted 1:1 Zoom interviews with 50 developers from various backgrounds, digging into their current challenges and the solutions they were using. A common theme emerged: developers were fed up with the inaccurate code snippets and explanations from generalist AI tools. They wanted a reliable, dev-focused alternative.
在编写一行代码之前，我想深入了解目标用户的需求和痛点。我对 50 名来自不同背景的开发人员进行了 1：1 的 Zoom 采访，深入探讨了他们当前面临的挑战以及他们使用的解决方案。一个共同的主题出现了：开发人员厌倦了来自通用人工智能工具的不准确代码片段和解释。他们想要一个可靠的、以开发为中心的替代方案。

Building the Solution: Devv, an AI-Powered Search Engine for Devs
构建解决方案：Devv，面向开发人员的 AI 驱动的搜索引擎

Armed with this key insight, we got to work building Devv. Our goal was to create an AI search engine that could provide trustworthy, error-free answers to coding questions and generate clean, functional code snippets.
有了这个关键的见解，我们开始着手构建 Devv。我们的目标是创建一个人工智能搜索引擎，为编码问题提供值得信赖、无错误的答案，并生成干净、实用的代码片段。

Under the hood, Devv is powered by RAG (Retrieval-Augmented Generation) and large language models. To ensure the most relevant and accurate results, we built our own specialized search indexes spanning development-related websites, official documentation, and open-source code repositories.
在引擎盖下，Devv 由 RAG（检索增强生成）和大型语言模型提供支持。为了确保最相关和最准确的结果，我们建立了自己的专业搜索索引，涵盖与开发相关的网站、官方文档和开源代码库。

To validate our idea quickly, we challenged ourselves to build and launch an MVP within just 1 week. The initial version was bare-bones but functional, focusing solely on solving the core problem of unreliable AI code generation and answers. After shipping the MVP to a small group of friends and colleagues, the feedback was overwhelmingly positive. Developers loved having an AI tool they could actually trust for their day-to-day coding needs. This gave us the confidence to keep pushing forward.
为了快速验证我们的想法，我们挑战自己，在短短 1 周内构建并启动 MVP。最初的版本是简陋的，但功能强大，只专注于解决不可靠的人工智能代码生成和答案的核心问题。在将 MVP 发送给一小群朋友和同事后，反馈非常积极。开发人员喜欢拥有一个他们可以真正信任的 AI 工具来满足他们的日常编码需求。这给了我们继续前进的信心。

Differentiating Devv in a Crowded Market
在竞争激烈的市场中实现 Devv 的差异化

We knew we weren't the only generative search engine out there. Competitors like Perplexity, You.com, and Phind had already established themselves in the market. While they also utilized Google or Bing search results for up-to-date information, we believed that to truly serve developers, we needed to go a step further.
我们知道我们并不是唯一的生成式搜索引擎。Perplexity、You.com 和 Phind 等竞争对手已经在市场上站稳了脚跟。虽然他们也利用 Google 或 Bing 搜索结果来获取最新信息，但我们认为，要真正为开发人员服务，我们需要更进一步。

That's why we made the decision to build our own custom search index specifically tailored to development-related scenarios. In addition to integrating Google search, we crawled and indexed a vast array of developer websites, official documentation, and open-source code repositories like GitHub.
因此，我们决定构建自己的自定义搜索索引，专门针对与开发相关的方案进行定制。除了集成 Google 搜索之外，我们还抓取并索引了大量开发人员网站、官方文档和 GitHub 等开源代码库。

This exclusive focus on developer resources allowed us to provide more relevant and accurate results for coding queries. Rather than relying solely on general web results, Devv could draw upon a rich knowledge base of programming-specific information to answer questions and generate code snippets.
这种对开发人员资源的独家关注使我们能够为编码查询提供更相关和准确的结果。Devv 可以利用丰富的编程特定信息知识库来回答问题并生成代码片段，而不是仅仅依赖一般的 Web 结果。

To further differentiate Devv, we implemented two other key features:
为了进一步区分 Devv，我们实现了另外两个关键功能：

1. Agent Mode: For complex queries, Devv infers the user's intent and selects from specialized agent types (code generation, explanation, debugging, optimization, web searches) to provide tailored solutions.
   代理模式：对于复杂的查询，Devv 会推断用户的意图，并从专门的代理类型（代码生成、解释、调试、优化、Web 搜索）中进行选择，以提供量身定制的解决方案。

2. Clean, dev-focused UI: We designed Devv's interface to be clutter-free and intuitive, allowing developers to focus on their work without distractions from the tool itself.
   简洁、以开发人员为中心的 UI：我们将 Devv 的界面设计为整洁直观，使开发人员能够专注于他们的工作，而不会受到工具本身的干扰。

By combining our custom developer search index with these unique capabilities, we were able to carve out a compelling value proposition for Devv as the go-to search engine for developers. Our specialized approach set us apart from the more general-purpose offerings of our competitors.
通过将我们的自定义开发人员搜索索引与这些独特的功能相结合，我们能够为 Devv 打造一个引人注目的价值主张，使其成为开发人员的首选搜索引擎。我们的专业方法使我们有别于竞争对手的通用产品。

Finding Initial Traction in China
在中国寻找初步牵引力

With an optimized MVP in hand, it was time to get Devv in front of a larger audience. We started by sharing it with my existing Twitter following, which consisted mainly of developers based in China.
有了优化的 MVP，是时候让 Devv 出现在更多观众面前了。我们首先与我现有的 Twitter 粉丝分享它，这些粉丝主要由中国的开发人员组成。

The response exceeded our wildest expectations. Through word of mouth alone, Devv grew to over 500,000 users within just a few months. Developers across China were raving about the tool, and our user base was growing exponentially.
反响超出了我们最疯狂的预期。仅通过口口相传，Devv 在短短几个月内就发展到超过 500,000 名用户。中国各地的开发人员都对这个工具赞不绝口，我们的用户群也呈指数级增长。

But just as we were hitting our stride, disaster struck. Devv was suddenly blocked by the Great Firewall, cutting off access for all of our users in mainland China. In an instant, our primary growth engine disappeared.
但就在我们大踏步前进时，灾难降临了。Devv突然被防火长城封锁，切断了我们在中国大陆所有用户的访问。转眼间，我们的主要增长引擎就消失了。

Overcoming Adversity: Getting Banned in China
克服逆境：在中国被禁止

Losing our Chinese user base was a devastating blow, but we refused to give up. We knew we had built something of value, and we believed developers outside of China faced similar challenges.
失去我们的中国用户群是一个毁灭性的打击，但我们拒绝放弃。我们知道我们已经建立了一些有价值的东西，我们相信中国以外的开发商也面临着类似的挑战。

So we went back to the drawing board, adapting Devv for a global audience. We started from scratch, rebuilding our user base one developer at a time. Slowly but surely, we began to gain traction in other markets.
因此，我们回到了绘图板，为全球观众调整了 Devv。我们从零开始，一次重建一个开发人员的用户群。缓慢但肯定的是，我们开始在其他市场获得牵引力。

Rebuilding and Monetizing
重建和货币化

As our global user base grew, we started thinking about monetization. We wanted to build a sustainable business without compromising the user experience.
随着全球用户群的增长，我们开始考虑变现。我们希望在不影响用户体验的情况下建立可持续的业务。

In March, we launched a premium subscription plan for Devv. To our delight, it generated over $28,000 in revenue in the first month alone. And that number has only continued to grow in the months since.
3 月，我们推出了 Devv 的高级订阅计划。令我们高兴的是，仅在第一个月，它就产生了超过 28,000 美元的收入。从那以后的几个月里，这个数字一直在继续增长。

Today, Devv is helping developers across the world write better code, faster. And we're just getting started.
如今，Devv 正在帮助世界各地的开发人员更快地编写更好的代码。而我们才刚刚开始。
