Before / After: PDF Insight — from copying tables out of a PDF by hand to exporting the key points in seconds.
Problem: a client report arrived as a long PDF, and pulling the figures I needed meant opening the file, finding each table, and copying numbers into a spreadsheet by hand — slow, and one wrong cell broke the whole summary.
Build: I built PDF Insight with n8n and OpenAI — upload the PDF, ask for the figures and key points in plain English, and get a sourced answer that points back to the exact passage it came from, then export the key points.
Result: the same extraction now takes one question instead of an afternoon of copy-paste, and every number can be traced back to its source. What is the first thing you would ask a long PDF if you could trust the answer?

Automate your data processing, record-keeping, and email follow-ups with this powerful n8n workflow that connects Google Sheets and Gmail. With a single click (or any trigger you choose), the workflow prepares your data, validates it with custom logic, saves it to Google Sheets, emails the right person, waits for the right time, and then follows up automatically.
What problems it solves for clients and companies:
No more manual data entry or copy-pasting into spreadsheets
Data is cleaned, formatted, and checked automatically with custom JavaScript logic
Every record is saved and updated in Google Sheets, so your data stays organized and always up to date
Instant confirmation emails are sent to clients, customers, or team members
Automatic follow-up emails after a delay, so no lead or task is ever forgotten
Sheet status updates automatically, giving you a clear view of what has been done
Saves hours of repetitive work every week and removes human errors
Easy to scale and customize for any business process
How it works:
The workflow starts (manual click, form, webhook, or schedule)
Edit Fields and JavaScript code prepare and clean the data
The If condition checks whether the data is valid
The record is added to Google Sheets, and a Gmail message is sent
The Wait node pauses for the set time
The sheet row is updated, and a follow-up email is sent if needed
Perfect for sales teams, agencies, support teams, HR, recruiters, and small businesses who want smart email follow-ups and organized records without manual work. I can fully customize it to your sheet columns, email templates, delay times, and business rules.

I'd pick Light for an analysis tool, the charts and sources read better on a pale surface and the violet bars still pop. Dark works as the night option. Is the sources panel on the right open by default?
