I extracted the titles of the ~1,600 conversations I had with ChatGPT in 2025 so far and classified it against the list of How People Are Really Using Gen AI in 2025.
Here are the top 8 things I use it for, along with representative chat titles. (The % match in brackets tells you how similar the chat title is to the use case.)
- Improving code (clearly, I code a lot)
- Troubleshooting (usually code)
- Corporate LLM/Copilot (this is mostly LLM research I do)
- Generating code (more code)
- Generating ideas (yeah, I’ve stopped thinking)
- Simple explainers (slightly surprising how often I ask for simple explanations)
- Generating relevant images. (Surprising, but I think I generated a lot of images for blog/LinkedIn posts)
- Specific search (actually, this is mis-classified. This is where I’m searching for search engines!)
My classification has errors. For example, “Reduce Code Size” was classified against “Generating code” but should have been “Improving code”. But it’s not too far off.
Here’s a list of representative chats against these use cases.

How did I calculate this?
- On ChatGPT.com, I scrolled until I had all 2025 chats visible. Then I pasted
copy($$(".group.__menu-item").map(d => d.textContent))to get the chat titles. - On Claude.ai, I transcribed this list of use cases from HBR (prompt: “Transcribe this image”).
- On LLM Foundry (which you may not have access to), I used the Similarity API to get a CSV of similarities between prompts and top 30 use cases in 2025 using text-embedding-3-small.
- On ChatGPT.com, I told it to analyze the data like this:
This sheet has the embedding similarity between my ChatGPT prompts (in column “A”) with different use cases.
Write and run code that tags the prompt with the use with the highest embedding similarity (cell value), drops prompts whose highest embedding similarity is below a cutoff, and shows a table where the rows are the use cases and the values are the frequency. Do this for multiple embedding cutoffs as columns: 0.0, 0.1, 0.2, 0.3, 0.4. So, the table has use cases in rows, embedding cutoffs in columns, and the cell values are the count of prompts tagged with each use case AND have an embedding similarity >= cutoff. Draw this as a heatmap with low numbers as white and high numbers as green.
… and then:
Let me download this as a Markdown list in this style, sorted by descending order at cutoff = 0
- Anti-trolling (mention count of matches at 0 cutoff):
- Tor Technical AMA questions (34%)
- Bot Message Edits (33%)
- Popular Hacker News Keywords (33%)
- …
