An hour of research for one post became five ready ideas in seconds
A custom GPT that turns a topic, focus and timeframe into five sourced "on this day" facts ready to post or talk about.
This creator knew the value of sharing a good fact nugget but kept putting it off, because each one took an hour. So they built OnThisDay Researcher, a custom GPT that does the ground work in seconds. It is a clear example of turning a recurring chore into a small, useful tool.
Before
They wanted to show topic authority, create engagement and share interesting facts. But each post meant at least an hour of finding the fact, writing the text and making it relevant. So the post kept slipping to next week, and not only once.
“Takes at least 1 hr to find it, create a text, make it relevant. Oh - not today. Maybe... next week.”
In their own words
The turning point
They started by doing the task by hand in ChatGPT-4o and iterating until it worked. Then they asked ChatGPT to write custom instructions for a GPT that asks for a topic, a focus and a timeframe. After refining, an MVP test and a revision with GPT-o1, the tool was ready.
“Now? AI helps. A GPT does the ground work for me.”
In their own words
After
Now a GPT does the ground work for them. They type in a topic, focus and timeframe and get a selection of five options in seconds. They are already working on the next step, an API export to Infinity to keep a history and backlog of posts, and openly say the technical side has been a challenge.
What it lets people do
Anyone who wants to post with authority can get dated, relevant events with a short note on why each matters and a source to check. It turns a blank page into five starting points for a post or a talk.
What they learned
They learned that a tedious task becomes manageable once you test it manually, then hand the pattern to a GPT and keep iterating. They also stay honest about what is worth building next, questioning whether a feature solves a real problem.
“But I am not sure as copy/paste seems not a big issue.”
