Even an LLM-writing skeptic makes an exception
“I'm generally allergic to having an LLM write for me, but seeing as it _must_ be in the requested template and ChatGPT saves me a couple of hours, I let this case slide.”
Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.
What they did
Their company requires weekly updates in a specific format. They take notes throughout the week in Obsidian’s periodic weekly notes, then send them all to a custom GPT that writes the update in the template.
How it went
They spend about 10 minutes cleaning it up. Normally allergic to having an LLM write for them, they make an exception because ChatGPT saves them a couple of hours.
Try it yourself with ChatGPT
Here are my notes from this week: [paste]. Write my weekly update in exactly this template: [paste template]. Group items under the right headings, keep each bullet to one line, lead with outcomes rather than activity, and flag anything in my notes that looks like a risk or a blocker. Don't invent anything that isn't in the notes.

Consistent marking and actionable feedback, every time. A UK teacher's custom GPT marks essays for their subject, and the students now use it to revise.
Buying small e-commerce brands, they codified everything they look for into a six page prompt. Given a listing's screenshots and financials, ChatGPT takes a first pass to decide whether a seller call is worth taking.
Booking flights for a Costa Rica trip, a picky traveler asked ChatGPT to look them up. It checked Kayak, noticed the return flights got in too late and offered other options; they ended up booking one.
Completed orders needed checking against CRM records before billing. Every night ChatGPT reviews each order form against the CRM for mistakes, then creates a draft invoice in the accounting system for review.
Building their first AWS project by vibe coding, the writer designed the architecture and let Codex write the code. A flawed first design took a day, against an estimated three or four; the redesign also took a day and scaled.
Safari's lack of a favorite Chrome plugin was the writer's last complaint about it. ChatGPT pulled the source from their installed Chrome extension, ported it, and installed it in Safari in 20 minutes.
