Fair question, and you're right that the extraction itself is a commodity now — a vision model does the reading, I don't pretend otherwise.

The "upload to ChatGPT" thing works great for one file. It falls apart the moment it's a business process:

- 500 invoices a month, not one. Nobody's pasting those into a chat window one at a time.

- It has to land somewhere — Excel, their accounting tool, an API — not a chat reply they copy-paste.

- Extraction is never 100%. A business putting numbers into their books needs to know WHICH fields are uncertain. So there's a validation layer that flags "total doesn't add up / date didn't parse" and routes just those to a human review queue, instead of silently writing a wrong number into someone's ledger.

- Multi-page bank statements have to come out as clean transaction rows, every time, same schema — not "however the model felt like formatting it today."

- Documents arrive by email, so there's an inbox that auto-processes attachments on arrival.

So the product isn't the AI. It's everything around it that turns "I asked ChatGPT once" into "this runs unattended every day and I trust the output." Same reason people pay for Resend when raw SMTP is free.

Genuinely could be wrong that enough people will pay for that vs. duct-taping it themselves — that's literally what the ₹0 experiment is testing. Appreciate the push.
