## A Familiar Scenario

A Familiar Scenario

Independent developers and small teams have probably all experienced moments like this: you spend a weekend writing a thirty-page technical proposal document, complete with architecture diagrams, technology comparison, and risk analysis. You post it to the group chat, and what you get back is—

• Your co-founder replies "I'll look at it later," and that's the last you hear of it;
• The client flips to page three and asks "So which option are we going with, and how much does it cost?";
• At the team review meeting, everyone starts flipping through the document on the spot, and after two hours of discussion you still haven't gotten to the point.

The problem isn't the quality of the document—it's that nobody has the patience to read a long document before making a decision. Decision-makers don't need the process; they need one page: what the plan is, what was chosen, how much it costs, what the risks are, and when it can launch.

In the past, compressing thirty pages into one relied on a senior engineer's experience and at least half a day of repeated editing. Now, AI can handle most of this for you.

Why AI Is Suited for This Task

Document summarization sounds like AI's bread and butter, but a "decision summary" is different from an ordinary summary. An ordinary summary condenses content; a decision summary must answer the questions decision-makers actually care about:

• What are the alternative options, and what are the trade-offs of each?
• What is the core rationale for the recommended option?
• What are the key numbers for cost, timeline, and risk?
• Which items must be decided now, and which can be deferred?

This is exactly the kind of work LLMs excel at: long-text comprehension, structured extraction, and reorganizing information according to a fixed framework. What you need to do is not ask AI to "summarize this for me," but give it a clear decision-summary framework.

My Workflow: Three Steps

Step 1: Prepare the Material

Give the complete technical proposal document to the AI. It can be Markdown, text exported from a PDF, or you can paste it directly. The only requirement is that the document itself contains complete information—AI can only compress information; it cannot fill in content you never wrote.

Step 2: Generate a First Draft with a Structured Prompt

This is the core of the entire process. I use a fixed prompt template so the AI outputs a one-page summary in a consistent format:

你是一位资深技术顾问，擅长把冗长的技术方案压缩成决策层一眼能看懂的摘要。

请阅读以下技术方案文档，输出一份一页决策摘要（中文，总量控制在800字以内），严格按照以下结构：

1. 【一句话结论】这个方案要做什么，推荐哪个选项，预计投入多少（人天/费用区间）。
2. 【备选方案对比】用表格列出2-3个备选方案，维度包括：实现成本、工期、维护负担、主要风险。每格不超过15个字。
3. 【推荐理由】最多3条，每条一句话，必须引用文档中的具体数据或事实。
4. 【关键风险】最多3条，每条附一句应对措施。
5. 【待决策事项】列出需要决策者现在拍板的问题，每个问题给出建议选项。
6. 【时间线】关键里程碑，不超过5个节点。

规则：
- 只使用文档中出现的信息，不得编造数字
- 文档中缺失的信息，标注[文档未提及]
- 删除所有技术细节描述，只保留影响决策的内容

Step 3: Manually Verify the Key Numbers

The AI may rephrase wording and distill arguments, but cost figures, timelines, and risk levels must be checked by you against the original document. My usual practice is to have the AI list all cited numbers in a separate section at the end, then verify them one by one. This step takes five minutes, but it prevents the disaster of "the summary had wrong numbers, and decisions were made based on them."

Before and After: Doing the Math

Using one of my own real use cases as an example (personal experience, not client data):

Roughly speaking, the total time from "document written" to "decision made" for a proposal went from three or four hours down to about half an hour. For a small team, the biggest gain actually isn't those few hours—it's the decision speed. Proposals no longer sit in the group chat for a week; they can be settled the same day, and the overall project delivery cycle shrinks noticeably.

At a rate of four or five proposals per month, the time saved over a year adds up to nearly a full working week. For a one-person team, that's tangible extra capacity.

A Few Practical Tips

1. Have the AI ask questions before summarizing. Add a line at the end of the prompt: "If key decision-making information is missing from the document, list the questions first before outputting the summary." This surfaces gaps in the document itself early.
2. Keep the link to the original. Attach a link to the full document at the end of the summary. Anyone who wants to dig deeper can go read it themselves—the summary serves decision-making only.
3. Build up versions. Reuse the same template. Once the summary format stabilizes, the team develops a shared understanding that "this one page is enough," further reducing communication costs.
4. Turn it into an API. If you produce proposal documents frequently, you can wire this workflow into an API call, automatically generating and pushing a summary whenever a document is submitted. For the pricing of related services, refer to the official pricing page—for one-off tasks of a few thousand tokens like this, the cost is usually negligible.

Final Thoughts

Turning a long document into a one-page decision summary is essentially productizing "the information triage skills that only senior engineers used to have." AI handles compression and structuring; you handle verifying the numbers and making the final call—this division of labor lets a one-person team produce decision materials at the level of a large company.
