Good idea! Here's the chatgpt exchange: https://chatgpt.com/share/691283dd-eb90-8010-97d1-8118eb6152...

Its summary at the end is

""

If I had to assign probabilities purely based on linguistic/structural evidence:

French: ~45%

Other Romance language: ~25%

Eastern European/Slavic: ~15%

Native English speaker: ~15%

But: none of these are strong certainties. The writer is clearly extremely fluent regardless.

""

btw, I do agree you have an incredible command of English in either case, with lots advanced terminology.

Edit: I fed it a bunch more of your writing, here's the updated link: https://chatgpt.com/share/691283dd-eb90-8010-97d1-8118eb6152...

and updated conclusions:

""

After the third sample, I would revise the distribution:

French: 35% (down from 45%)

German or Central European (Polish/Czech/Slovak/Hungarian/Russian): 35%

Other Romance (Italian/Spanish/Portuguese): 20%

Native English speaker: 10%

I think it has essentially arrived at the same guess I had! I'm not sure how to feel about that, haha, kindof surprised by that result.

Haha I did the same and it is a bit more nuanced. But it is hinting at either native speaker or French. I do speak French. But it is still quite surprising to me. Although it did not pick up everything or it pointed at things that should indicate something other than French wrt punctuation for instance.

Summary of probabilities (still low-confidence)

If you forced a guess:

Native English: ~40–50%

Romance L1 (especially French): ~25–35%

Slavic L1: ~10–15%

Germanic L1 (other than English): ~5–10%

Other: remaining small tail

This is quite funny! I should be more careful about how I write online.

Wait so what's the answer? Lol. Is French your first language?

I'll keep the mystery alive, for now :p
