EncodeKey
Text, emoji, and ciphers
Free · Designed for iPad. Not verified for macOS.
Turn everyday messages into expressive emoji, Morse, Caesar, or custom-key cipher text.
EncodeKey is a playful encoding keyboard and companion app for turning everyday text into expressive formats.
Use Emoji mode to convert meaning-first words and phrases into emoji. Because emoji can have many meanings, decoding shows possible interpretations instead of pretending every emoji has only one answer.
You can also use standard encoding modes like Morse code and Caesar shift, or create private text with a custom key phrase.
Highlights:
- Meaning-first emoji conversion
- Emoji decode with possible meanings
- Morse code encoder and decoder
- Caesar cipher encoder and decoder
- Custom-key text cipher
- Custom keyboard extension
- Dictionary support across English, Vietnamese, Indonesian, Malay, Spanish, French, Portuguese, German, Japanese, Korean, and Thai
EncodeKey is built for fun chats, lightweight privacy, language play, and expressive messages.
