Speech - Introduce Theing LangCorrect

LangCorrect is a proper noun, just like someone's name, so you don't need "The."

I've written a draft of my speech draft and I hope you can point out any errors to me?.

While "speech draft" makes sense and is correct, it is more natural to say "draft of my speech."

Because you didn't write a question, you do not need to use a question mark. You could also say "... and I would appreciate it if you point out any errors to me."

I'm a little nervous because I'm not used to giving such speeches in English.

You could also say "speeches like this in English," which is what I think you were using "such" for.

sSo please go easy on me.

Today I want to introduce a social networking service that will help you learn English, especially writing in English.

You could also use "specifically" instead of "especially," since LangCorrect is more focused on writing (and reading) than speaking or listening.

You can also correct sentences that were written in your native language by other users who are learning it.

This is my composition in English that I posted to LangCorrect.

Each sentence is corrected and you can see what was correcthanged.

The speech is getting a little repetitive with "corrected" so many times close together. I would try to use other words, or work on these sentences to avoid that.

HeAnother user corrected themy sentence to say "It smells like a stinky bug and feels like grass in my mouth".

On the other hand, if a user who issomeone learning Japanese posts sentences, users, including me as a native who speaker of Japanese, like me, will receive a request to correct it.

Your original sentence wasn't too wrong, but it felt long. I reworded it a bit to be shorter, simpler, and sound more natural. Having "user" twice without a clear difference between them can be confusing.

Then we can correct their sentences and reply to them.

This is correct, but you could also say "Then we can correct their posts and comment on them."

Having a native speaker correct your writing will help you practice writinge more natural sentencesly.

The original is good, but if you're better at practicing writing, then you are better at writing in general.

I started thisusing LangCorrect in July 2020 and I have posted 6 sentencries on it.

I'm assuming you've posted more than just six sentences! You could also say "...I have composed 6 posts" instead.

It has a function to allow becoming friends with other usersalso has a "friend" function, I would be happy if you could add my account, Onodak, as a friend.

Speech - Introduce The LangCorrect

Is it "the" LangCorrect? I think maybe not.

So, I think it might be better "help you improve your English, in particular your written English." In part because it's more a practicing and feedback site than a teaching/didactic one, but also because I couldn't find a noun that went well there other than "composition." It's specific, but maybe not familiar to your audience. The verb "writing" is better, but it needs a different set-up.

LangCorrect is a language learning web service run by thethat is community-led.

It might help to give familiar examples here, like Reddit or ... Or in opposition: Not a pay-for-service or corporate website.

You can also correct sentences that were written in your native language by other users who are learning ityour native language.

I thought it was a little confusing without backing up and putting the antecedent, the thing being referred to.

This is my composition in English that I posted to LangCorrect.

Then users who are native English speakers corrected my sentences.

Maybe "corrected me sentence by sentence"

HeA LangCorrect user corrected the sentence to say "It smells like a stinky bug and feels like grass in my mouth".

On the other hand, if a user who is learning Japanese posts sentences, users, including me as a who are native speakers of Japanese like me, will receive a request to correct it.

Just an awkward relative clause order--and again missing a relative pronoun (who, which, that)
