Telegram will translate a message you cannot read, and on a paid account it will translate a whole conversation as it arrives. For anybody in international groups this quietly removes a barrier that used to end participation.
It is very good at giving you the gist and it is unreliable in a specific, dangerous way: the mistakes it makes are fluent. A wrong translation does not look wrong. This step is how to use it and where to stop trusting it.

public Two ways it appears
One message at a time. Hold a message, choose to translate, and a version in your own language appears. This is available to everybody, and it needs switching on once in the language settings — a surprising number of people have never seen the option because the button is off by default.
A whole conversation. With a subscription, a bar appears above a chat in a foreign language, and tapping it translates everything including messages that arrive while you are reading. This is the one that changes what is possible, because it turns a channel you could not follow into one you can.
Alongside both is the setting that actually makes the feature usable: a list of languages you do not want translated. Without it, the bar keeps offering to translate things you read perfectly well. Adding every language you are comfortable in means the offer only appears when it is genuinely useful.
Does the person who wrote the message know you translated it?
Translation is entirely on your side of the conversation, like muting or archiving. Nobody is told, no indicator appears, and there is no counter anywhere. That is worth knowing because it removes any social hesitation about using it — there is no version of this where somebody feels their message was treated as foreign. Write in whatever language is natural and let people read it however they need to.
Which part of a translated message deserves the most suspicion?
Vocabulary is what these systems are best at. What they get wrong, and get wrong without any sign of difficulty, is the small load-bearing material: a date rendered in a different order, a quantity that gains or loses a digit, a name turned into an ordinary word, and negation — where "do not send it before Friday" and "send it before Friday" are one dropped word apart. The rule that follows is narrow and worth keeping: read the translation for meaning, and read the original for numbers.
You translate a message inside a secret chat. What has happened?
Translating requires the text to reach a system that can translate it, which means it leaves the device. In an ordinary cloud chat that changes very little, since the message was already stored on a server. In a secret chat from Step 025 — whose entire purpose is that the content exists only on two devices — it undoes the reason for using it. The same reasoning applies to anything else that processes message text off the device, and it is the one place in this step where the answer is simply not to use the feature.
A translated message from a colleague reads as blunt and slightly rude. What is the most likely explanation?
Registers of politeness are carried very differently between languages — by verb forms, by particles, by conventional phrases with no equivalent — and they are among the first things to disappear. A message that was courteous in its own language routinely arrives as a bare instruction. The practical habit is to suspect the machine before the person, and in the other direction, to be a little more explicit than feels natural when you know you are being read in translation.

rule Writing to be translated
Half of this subject is reading and the half nobody discusses is writing. If you post in a group where people are reading you through a machine, a few habits make you dramatically easier to understand, and none of them require writing badly.
Short sentences survive. Long ones with several clauses are where structure gets lost, and the fix costs nothing — a full stop instead of a comma.
Put numbers and dates in an unambiguous form. Spelling the month rather than using a numeral removes the commonest failure outright.
Avoid idiom, sarcasm and wordplay for anything that matters. They either translate literally, which is confusing, or translate into nothing, which is worse in a group where somebody is trying to follow an instruction.
Say the important thing plainly, once. If a message contains a decision or a deadline, it should be a sentence on its own rather than embedded in a paragraph, because that sentence is the one people will read twice and check.
touch_app Try it now — five minutes
Four steps, and the second is the one that stops the feature being annoying.
- Switch the translate option on In the language settings. Until it is on, the option does not appear when you hold a message, which is why many people believe the feature does not exist.
- Add every language you actually read to the do-not-translate list Including the ones you only half read. This is what turns a bar that offers constantly into one that appears when it is useful.
- Translate something, then read the original next to it Find a message with a number or a date in it. Compare the two. Seeing the kind of mistake it makes once is worth more than being told about it.
- Check your own recent messages in a mixed-language group Look for long sentences, idioms and ambiguous dates. One edit to how you write is a permanent improvement for everybody reading you in translation.
content_cut What translation does to the parts that are not language
A message is not only words. It may contain a username, a link, a reference number, a code block, a hashtag or a piece of formatting, and translation treats all of it as text to be processed.
Usually that is harmless and occasionally it is not. Handles and addresses can lose their formatting in a translated view, so a name that was a tappable link becomes ordinary text. A reference that looks like a word can be helpfully rendered into another word. Spoilers and emphasis from Step 052 may not survive the round trip, which means a message whose meaning depended on formatting arrives without it.
The practical rule extends the one from the quiz above and is worth stating as a single habit: read the translation for meaning, and copy from the original. Anything that has to be reproduced exactly — a code, an address, an account number, a command — should be taken from the untranslated message, where you can be sure that what you are copying is what was sent.
It cuts the other way too, and this is the more useful half for anybody writing to an international audience. A booking reference or a wireless password placed in a code block, as Step 052 describes, is visibly a string rather than a sentence. That marks it as something not to be translated or retyped, and gives the reader a copy control that cannot introduce an error.
help Common questions at this stage
Can I reply in my own language and have it translated for them?
There is a paid feature that translates what you are composing, and it works the same way with the same limitations — fine for the substance, unreliable on numbers and tone. The safer pattern in an important exchange is to write in your own language, translate, and send both versions together. It looks slightly clumsy and it lets the other person check the original if something reads oddly.
Does translation work on captions, channel posts and file names?
Message text and captions, yes. Words inside an image are not text as far as any of this is concerned — the same limitation Step 045 describes for search — so a poster or a screenshot in another language cannot be translated in the app. That is worth remembering when posting to an international audience: an image with text in it excludes everybody who does not read that language, where the same words typed as a caption would not.
Is the translation stored anywhere?
Not in the conversation. What you see is generated for you when you ask for it, and the message itself is unchanged for everybody including you — turn the translation off and the original text is what remains. What happens to the text on its way to being translated is not something any user can verify, which is the honest reason this step recommends against translating inside secret chats rather than making claims about how it is handled.
Why does it sometimes translate a language I speak?
Because that language is not in your do-not-translate list, or because the message mixes languages and was detected as the other one. Short messages are the usual culprits: a few words can genuinely be ambiguous. Adding the language to the list is the fix for the first case, and the second is not worth chasing.
How good is it, honestly?
For following a conversation, deciding whether something concerns you, and reading a channel in a language you do not have — very good, and far better than nothing, which is the realistic alternative. For anything where the exact words carry weight — a contract, a medical instruction, a legal notice, a negotiation — it is a starting point rather than an answer, and the correct response is to get a person involved rather than to read it more carefully.
Should I run a channel in two languages?
It depends on whether the second audience is real. Posting everything twice halves the readability of the channel for everybody and doubles your work, so it is only worth it when a substantial part of your audience genuinely cannot read the first language. The alternative that often works better is a separate channel per language, linked from each other — readers get a clean feed, and you can see from the subscriber numbers whether the second one was needed.
