Secret Language — Hide a Message in Plain Text

A free secret-language tool that hides any message inside innocent-looking everyday text. Your words are encoded into ordinary sentences you can paste into any chat, and a recipient pastes them back here to recover the exact original — typos, emoji and all. No password, nothing to install, works right in your browser.

How to send a secret message

1
Type your secret

Write anything in the top box — any language, any length, emoji or typos all work.

2
Copy the cover text

The tool turns it into innocent-looking sentences; press Copy to grab them.

3
Send it anywhere

Paste the cover text into a chat, a post, a comment or an email.

4
The recipient decodes

They open this page, paste the cover text into the bottom box, and your exact message appears.

5
Keep it unchanged

Don't edit the cover words; if a tamper warning shows, the text was altered in transit.

Turn your message into ordinary words, then back into the original

0 characters
Try an example:
0 words

Heads up: phone autocorrect (T9) can change words and break decoding. If a message won't decode, turn off autocorrect or paste it unchanged.

Decode

This is a fun secret language, not encryption. Anyone with this tool can decode it — share the trick only with people you trust.

Why this secret language is different

Lossless and exact
Every character comes back exactly — including typos and emoji — because your message is encoded as raw UTF-8 bytes, not translated by meaning.
Survives any messenger
The cover text is only ordinary words, spaces and punctuation — no invisible characters — so it pastes cleanly into Telegram, WhatsApp, Discord, email and more.
Built-in tamper check
A CRC32 checksum warns you when the cover text was edited or cut off, instead of silently returning the wrong message.
Russian or English cover
Cover words are Russian on the Russian site and English everywhere else — yet you can hide a secret written in any language.
No password, instant, in your browser
Encode and decode on one page, with no sign-up and nothing to install; once loaded it keeps working offline.
Natural or plain style
Pick flowing sentences or a compact list of words — both decode to exactly the same message.

What you can do with it

  • Send a note that looks like an ordinary message to everyone but your friend.
  • Build puzzles, treasure hunts, escape-room clues and ARG riddles.
  • Drop a hidden message into a social post, bio or comment.
  • Pass a quick code between people who both know the trick.

Why use a secret language

Sometimes you want to send something in plain sight — a playful note, a puzzle clue, an inside joke — without it obviously looking encrypted. This secret language hides your message inside grammatical, everyday-looking text that travels through any chat untouched, and returns the exact original to anyone who runs it back through the tool. It is built for fun and casual secrecy, with an honest promise: it is robust and lossless, but it is obfuscation, not encryption.

Frequently asked questions

Will the cover text survive copy-paste in messengers?

Yes. The cover text is made only of ordinary words, spaces and standard punctuation, with no invisible or special characters, so it travels safely through Telegram, WhatsApp, Discord, Slack, email and most other apps.

What happens if the cover text gets edited?

A built-in checksum detects it. Instead of quietly returning a wrong message, the decoder shows a "this cover text was edited or cut off" warning. Keep the cover text exactly as generated for a clean decode.

Is this encryption?

No. It is reversible obfuscation — it disguises your message as plain-looking words, but it is not secure encryption. Anyone who knows about this tool can decode the text, so treat it as a fun secret language, not as protection for sensitive data.

What can I hide, and what language is the cover text?

You can hide a message in any language and any length, with emoji, punctuation and even typos. The cover text itself reads as Russian on the Russian site and as English elsewhere, regardless of the language of your secret.

Why does the cover text read so strangely?

The words are chosen by your message's data, so the sentences are grammatical but surreal — a bit like dream poetry. That is normal and is exactly what lets the message decode back perfectly.

Does the recipient need anything special?

Only this page. They paste the cover text into the decode box and read your message. The method is public, so it is security by obscurity — handy for fun and casual secrecy, not for guarding important secrets.

Does it work offline?

Yes. Once the page has loaded, encoding and decoding run in your browser and keep working without a connection.
