invisible-message-facebook.mp4
This is a tool (userscript) for encoding/decoding Facebook Messenger messages to invisible characters
(Thanks to zws for the zero width characters table: https://github.com/zws-im/tools)
You're free to re-use the source code, but please keep the credit
The tool will be hooking into your Facebook messenger's React component to support 2 main features:
- Encode your message into invisible messages (on demand)
- Decode invisible messages sent by you and others to the normal/readable format
- No manual interaction required (no manual scripting/injection into dev console, blah blah,...just install once and use forever)
- Easy to use
- Sent messages remain fully invisible when you turn off the tool, fully invisible on mobile devices
- v0.8: Now with inline hidden messages
- v0.10: Now you can put hidden text between other visible texts. Syntax changed to:
> text <
- Install Tampermonkey
- Install my userscript from here
- Turn off your Facebook/Messenger tab and open it back again (to reflect the changes)
- When you need to encode a message, add ">" at the beginning of the message. Example: >Hello
