I'm starting to study English.

HeIt said youto use “'langcorrect'.

I recognalized genius Langcorrect is genius.

I am beginning to study English / I have start toed studying English.

Either of these would be good. The second option is more like how you started. The difference is the second option makes it sound like you started studying in the recent past, while the first option makes it sound like you're starting by writing this post.

When it comes to time, I can speak English.

This sentence literally means 「ときは、英語を話せる」, maybe this phrasing makes more sense in Japanese, but in English, it's not clear what connection time has to your ability to speak English.

I asked to ChatGPT.

"ask to" is used like "asked ChatGPT to suggest options" - the target goes after "ask"/"asked", and the request usually goes after the "to". In this case, since you explain the request in the next sentence, it's ok to stop with just "I asked ChatGPT".

HeIt said "you should use “langcorrect."

This could change since AI is still relatively new, but people use gender-neutral terms like "it" for AI

I recognized Langcorrect isas a genius idea.

This might be a little stronger than you intend - it's a very strong statement.

First tTime !

I am starting to study English.

I have used this phrase many, many times.

This would be common in casual speech. For formal speech or writing, only use one “many.”

When it comes to tithe time comes, I can speak English.

I asked to ChatGPT.

How should I study English?

Combine the previous sentence and this one. “I asked ChatGPT, “How should I study English?”’

He said youto use “lLangcorrect.

I recognized that Langcorrect is genius.

This sounds very casual. To give a more formal sound appropriate for writing say something like “I recognized that Langcorrect is a genius tool.”

First tTime !

I have used this phrase many, many times.

When it comes to time, I can speak English.

I have used this phrase many, many times.

When it comes to timeI need to, I can speak English.

I wasn't 100% sure what you meant, but this sounds like a good option in your context.

I asked to ChatGPT.

It's always "ask + noun" when it's a question.

How should I study English?

This should really be one sentence: I asked ChatGPT how I should study English.

He said youtold me to use “langcorrect." Or "He suggested I use Langcorret"

I recognized that Langcorrect is genius.

I'm starting to study English.

I have used this phrase many, many times.

When it comes to time, I can speak English.

I asked to ChatGPT.

How should I study English?

It would be better to combine these two sentences in one of these ways:
I asked ChatGPT how I should study English.
I asked ChatGPT, "How should I study English?"

HeIt said y, "You use “lLangcorrect."

I recognalized Langcorrect is a genius idea.

Your sentence is grammatically correct, but sounds a little awkward.
