Extracting Structured Data from Documents with an LLM and a Self-QA Step

The problem

Getting an LLM to pull numbers out of a PDF or press release is easy in a demo. Doing it for thousands of documents a day is not: the model grabs last year's figure instead of this year's, confuses net result with operating profit, invents a value when the field is missing - and you have no reliable way to know which outputs to trust. Adding more instructions to the prompt makes it slower and not much better, and stakeholders want an accuracy number you can't give them.

The solution

A walkthrough of the pipeline I run product on for financial disclosures: a configurable taxonomy to find candidates, a focused extraction prompt per datapoint, then an LLM QA pass that returns OK/KO with a reason - plus how we measure quality and latency. Client data stays private; I show the design. Or bring your extraction use case and we review prompts, schema and evaluation live.

How the session works

Live demo & walkthrough

The expert opens their real project and shows how it works: the setup, the decisions behind it and the pitfalls they hit along the way.

Setup review & troubleshooting

You show your screen or project. The expert walks through it with you, points out what to improve and gives concrete recommendations.

Which format fits depends on your focus - you pick it when you book.

FAQ

Before you book

What is a WIDMN session?

A 1:1 working session with a practitioner who has already solved your kind of task in real life. No theory, no slide decks, no courses. Depending on the case, the expert shows their real setup, reviews yours, or works through your questions with you.

Why not just ask AI or watch a tutorial?

Docs, YouTube and AI assistants are strong on the ideal path. What they can't give you is what a practitioner carries in their head.

Where it actually breaks: the limit that quietly eats your budget, the workaround that isn't written down anywhere.

What you didn't know to ask: an expert looks at your setup and flags the security hole, the rate limit, the cost trap waiting two weeks down the road.

Your screen, not a generic example: you can't paste a live workflow and error logs into a chat. On a call the expert watches your actual setup and tells you what to change.

What's the difference between a coffee chat and a case session?

Coffee chat: many experts offer one - a short, free call to check the fit. Meet the expert, describe your task and hear straight whether they can help with it. Not a free consultation.
Case session: focused time around your task. It may be paid or free. The expert shows how they built their solution, or reviews your setup and gives concrete recommendations - the exact format depends on the case and what you need.

What if the expert doesn't offer a coffee chat?

Then describe your problem in as much detail as you can when you book. The expert reads it before the call. If your task is outside what they can help with, the booking is cancelled and you are not charged.

What happens on a deep dive call?

Two formats, and you pick the focus when you book:
Live demo & walkthrough: the expert opens their real project and shows how it works - the setup, the decisions behind it and the pitfalls they hit along the way.
Setup review & troubleshooting: you show your screen or project, the expert walks through it with you and gives concrete recommendations on what to improve and how to get unstuck.

What exactly do I get in a deep dive?

An honest read on your own situation from someone who has built this: what in your setup holds and what doesn't, the pitfalls you'd otherwise find out about the hard way, and concrete next steps you can take on your own. You leave knowing what to change first.

How is this different from a course or agency consulting?

A course gives you static material for everyone - at 300 EUR or more. An agency takes over the work - at 5,000 EUR or more. WIDMN is in between: one focused session with a person who actually runs this in production, shaped around your task. It's peer-to-peer, so the expert won't do the work for you - but you'll leave with a clear plan and a pattern that already works.

Why pay for a deep dive?

You pay for someone's honest read on your task, not for information - that part is free. If the expert offers a coffee chat, use it to check the fit first. Otherwise describe your problem in detail when booking: if it's outside their scope, the booking is cancelled and refunded in full.

How do I prepare?

Bring your real context: the task you're working on, what you have tried, and 1-2 questions you would like to explore. That's enough - the expert can shape the conversation around what matters to you.

Can I get a refund?

Yes, in three cases. If you cancel at least 24 hours before your session. If the expert doesn't show up. And if your task turns out to be outside the expert's scope - we cancel the session and refund you in full. Refunds go back to the card you paid with.

What if something goes wrong?

If a session can't happen or didn't go as it should, write to widmn.contact@gmail.com - we'll sort it out, including a refund where it's fair.
