Pull invoices from Gmail and organize them
According to the write-up, the poster assembled Invoice Agent for teams that still handle vendor invoices through email. It connects to Gmail or Outlook, detects incoming invoice emails, uses AI to extract the key details, and puts them into a searchable place; at the time of the post, the human’s role was still validating the workflow, pricing, and positioning through feedback. The post gives no usage or accuracy numbers yet; it presents the product as a side project in validation.

Why it matters
Email is where a lot of admin quietly piles up. An agent that can read, sort, draft and follow up turns an inbox from a to-do list into something closer to a summary. It is one of 106 sightings filed under Email & Inbox on Agent Sightings (number 75 by interest), and one of 182 involving Custom agent.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into your own agent or any similar agent and adjust the details to your situation.
Go through my mail for this goal: pull invoices from Gmail and organize them. Propose labels, drafts, and unsubscribes as a checklist; change nothing until I approve.
Tip: Start with read-only access or 'draft, don't send', and check a few drafts before trusting it to send anything.
