Jag fick hjälp i chatten, även om jag trodde att ingen skulle svara så sent.

Yes. Swedish very often uses få hjälp = get help where English might also say get help or receive help.

So:

• Jag fick hjälp = I got help
• literally, I received help

This is a very natural Swedish expression. Swedish does not need a passive form here. Saying something like Jag blev hjälpt is possible in some contexts, but it is much less neutral and much less common for this everyday meaning.

Because hjälp here is being used as an uncountable noun, like help in English.

Compare:

• Jag fick hjälp = I got help
• Jag fick en hjälpande hand = I got a helping hand

In the sentence, hjälp means assistance in general, not one help as a countable thing.

I chatten means in the chat.

A few things are happening here:

• chatt = chat
• chatten = the chat
  The ending -en is the definite article attached to the noun.

So:

• i chatt would sound incomplete or unnatural here
• i chatten refers to a specific chat, such as the support chat or message thread

As for i vs på:

• i chatten is the most natural way to say in the chat
• på chatten may sometimes appear in certain contexts, but i chatten is the standard choice here

Även om means even if or even though, depending on context.

In this sentence, it introduces a contrast:

• Jag fick hjälp i chatten = one thing happened
• även om jag trodde att ingen skulle svara så sent = despite what I thought

So here it works like even though.

You can think of även om as a fixed expression. Learners should usually memorize it as a unit.

Because the speaker is referring to what they thought at that time in the past.

• tror = present: think / believe
• trodde = past: thought / believed

The first part is already in the past:

• Jag fick hjälp = I got help

So it makes sense that the thought is also placed in the past:

• jag trodde = I thought

Because att introduces a subordinate clause, like that in English.

• Jag trodde att ingen skulle svara = I thought that no one would answer

In English, that is often optional:

• I thought no one would answer

In Swedish, att is very commonly kept after verbs like tro when followed by a full clause. It sounds natural and clear here.

Because ingen means no one / nobody, while någon means someone / anyone.

So:

• ingen skulle svara = no one would answer
• någon skulle svara = someone would answer

The speaker expected no reply, so ingen is the correct choice.

Also note that ingen can mean:

• no one
• nobody
• sometimes none, depending on context

Skulle svara is the natural way to express would answer here.

The sentence is reporting a past thought about the future:

• at that earlier time, the speaker thought an answer would not come later

This is a common pattern in Swedish:

• present perspective: ingen kommer att svara = no one will answer
• past perspective: ingen skulle svara = no one would answer

So skulle is not just a conditional word; it is also often used as the future seen from the past.

Because this is a subordinate clause, and Swedish subordinate clauses usually keep the subject before the finite verb.

Structure here:

• att = subordinator
• ingen = subject
• skulle = finite verb
• svara = infinitive

So:

• att ingen skulle svara = correct
• att skulle ingen svara = incorrect

A useful rule:

• In main clauses, Swedish often has verb-second word order.
• In subordinate clauses, that pattern does not apply in the same way.

Så sent means so late.

• så = so
• sent = late (adverb form)

Why sent and not sen? Because it modifies the situation of answering, not a noun.

Compare:

• Det är sent. = It is late.
• De svarade så sent. = They answered so late.

So så sent is an adverbial expression describing the time of the action.

Because sen is the common adjective form, while sent is the t-form and is also used adverbially in expressions like this.

In this sentence, sent functions adverbially:

• svara så sent = answer so late

You will often see:

• Det är sent. = It is late.
• Hon kom sent. = She arrived late.

So learners should get used to sent as the normal form in many time expressions.

Because även om introduces a subordinate clause that comes after the main clause here.

The structure is:

• Jag fick hjälp i chatten = main clause
• även om jag trodde att ingen skulle svara så sent = subordinate clause

Since the main clause comes first, it keeps normal main-clause order.

If the sentence began with the subordinate clause, then the following main clause would show inversion:

• Även om jag trodde att ingen skulle svara så sent, fick jag hjälp i chatten.

Notice fick jag after the initial subordinate clause, not jag fick.

Not exactly, though they can sometimes express a similar contrast.

• även om = even though / even if
• fast = often though / although in spoken Swedish
• men = but

In this sentence, även om is a very good choice because it clearly introduces a concessive idea: something happened despite the speaker’s expectation.

Possible alternatives:

• Jag fick hjälp i chatten, fast jag trodde att ingen skulle svara så sent.
  This is more conversational.
• Jag trodde att ingen skulle svara så sent, men jag fick hjälp i chatten.
  This changes the structure and emphasis.

So även om is slightly more formal and neatly fits the sentence as written.
