sebg··on Ask HN: Workflow to generate complex proposals with AI
Got it—no constraints, mostly PDFs in → PDFs out, with 90% of answers covered in a Google Doc answer bank.

Given that, here’s a streamlined approach:

1. Extract RFP Content

Azure Form Recognizer, AWS Textract, or Adobe Acrobat API can extract text and structure from PDFs.

If RFPs follow a standard layout, LlamaIndex or LangChain can help chunk and categorize sections.

2. Retrieve and Insert Answers

Use Google Docs API to pull relevant responses based on keyword or semantic search.

OpenAI Assistants API or Claude 3 can rephrase and tailor the responses dynamically.

3. Automate Formatting with a Template

Microsoft Copilot (Word/Excel + SharePoint):

Copilot can fetch Google Doc answers and insert them into a predefined template.

If you standardize the output format in Word, you can generate a PDF-ready final draft.

Alternative: Python + Pandoc + Jinja2 templates if you want a more controlled workflow.

4. Output Final PDF

Convert the formatted document to PDF using Word’s built-in save-to-PDF, Pandoc, or LibreOffice headless mode.

** Low-Code Implementation

If you're looking for minimal coding:

Microsoft Power Automate + Copilot → Automatically extract, populate, and format RFP responses.

Zapier + OpenAI + Google Docs → Retrieve answers, format them, and push to a doc/PDF.

Would Copilot’s Word integration work within your workflow, or do you need more automation for final formatting?

If you want a completely hands-off approach, a small workflow automation script could eliminate the remaining 20% of manual work.

sebg··on Ask HN: Workflow to generate complex proposals with AI
You could build an AI-powered RFP response assistant using a combination of document automation, retrieval-augmented generation (RAG), and a structured workflow.

I'm thinking something like:

1. Extract and Parse the RFP

Use an LLM for summarization and section extraction.

Leverage OCR tools (e.g., Tesseract, AWS Textract, or Azure Form Recognizer) if the RFPs are PDFs with scanned text.

Convert the RFP into structured data using LangChain’s document loaders or Unstructured.io.

2. Automate Reusable Content Insertion

Maintain an answer bank (e.g., .txt, .md, Notion, Airtable, Google Docs, or even a vector database like Weaviate or Pinecone).

Implement retrieval-augmented generation (RAG) to pull relevant answers dynamically.

LlamaIndex or LangChain can help fetch the closest responses.

Use Embeddings (OpenAI, Cohere, or Ada models) for semantic search.

If a response needs tweaking, allow the AI to highlight differences and suggest edits.

3. Prompt for Missing Information

If the AI detects missing information:

Generate a draft response using context from existing data.

Provide a structured form/UI (e.g., Google Forms, Typeform, or an internal dashboard) for manual input.

4. Generate the Final RFP

Use LLMs to rewrite responses for coherence and consistency.

Automate formatting with Markdown-to-PDF tools (Pandoc, LaTeX) or Microsoft Word templates.

Consider using Zapier or Make.com to integrate responses into a shared document repository. Low-Code/No-Code Approach

If you want minimal coding:

Microsoft Copilot (Word + Excel) or Google Gemini AI could automate drafting and inserting responses.

Zapier + OpenAI + Google Docs can build a pipeline to parse, retrieve, and generate answers. Notion AI can assist in structured knowledge retrieval.

Would love to hear more about your constraints (e.g., compliance needs, integration with existing tools) to refine this further.

sebg··on Math Academy pulled me out of the Valley of Despair
It really depends on how much your son wants to do math.

As you can imagine, there is a whole world of kids like your kid who love math and want to do nothing more than math.

If you're interested I can chat with you or recommend resources here if you decide to help your kid do more math.

sebg··on What about K?
A companion guide that I always recommend if interested in K is: Q for mortals, found here - https://code.kx.com/q4m3/

Note, from wikipedia: Q serves as the query language for kdb+, a disk based and in-memory, column-based database. Kdb+ is based on the language k, a terse variant of the language APL. Q is a thin wrapper around k, providing a more readable, English-like interface.

sebg··on Ask HN: How to passively prepare for a job interview?
You don't :)

Seriously though, the pitch is: "I want to get a job in what you're doing, and you have that job; I'd love to learn more."

sebg··on Ask HN: How do I get good at math as a 42yo with kids?
You could also try beast academy and aops. We are huge huge huge (did I mention huge?) huge fans of them and have worked through pretty much all of their classes (1st grade through pre-calculus thus far).

Beast academy is around 15/20 a month and apps is more but you can just buy the book and work through it. Richard (the aops co/founder) has a ton of YouTube videos as well.

A third option is aops’s alcumus - which is a free math problem database. We use that a bunch as well and you could use it to figure out what you know and don’t know

sebg··on Ask HN: How to passively prepare for a job interview?
- scan indeed for jobs that appeal to you

- look at keywords they mention

- figure out if you know what those keywords are (what it means, why you would do that, why it's better than prior solutions, some real world examples)

- after a few weeks of this, you'll have a list of companies and words that you're interested in

- go on linkedin (or HN) and look for people working either at those companies and/or using those words

- ask them for a 15 minute chat to hear how they are approaching the problems you're interested in (not for a job, but to hear how they talk about it)

- use what you learned from the previous step to write some blog posts / articles / tutorials / tiny projects that let you see how much you know and then can later show people when you apply to those jobs

- reach out to the groups / companies you want to work and say that you're interested in that area and if you could have a chat about the work they are doing.

- remember that a) everyone is always hiring even if they don't have a job post, b) most job posts never make it public, c) shoot your shot

sebg··on Ask HN: How do I get good at math as a 42yo with kids?
https://www.mathacademy.com/ is probably the most popular HN response.

It's expensive at $50 per month, but it seems highly thought of if you look at Algolia (https://hn.algolia.com/?q=math+academy).

I haven't used it myself, but I am evaluating it for my kids to use.

It's too early to give feedback on that front, though.

sebg··on Ask HN: Important works that haven't been translated into English
There are a great deal of math articles/books in Latin, French, and Russian that have no English translations at this point.

For example, Euler wrote 800 articles (in Latin and French) and only 207 have been translated into English.

Examples of works in the French language:
