Baltic Cyrillic Alphabet Translator Online

Convert Latin-script text into the Baltic Cyrillic alphabet, or turn Baltic Cyrillic characters back into Latin, letter by letter using a fixed 33-letter map. Unlike a bare two-box converter, it states the direction, shows the mapping used, and preserves punctuation, digits, and unsupported characters instead of dropping them. Try it online.

What is the Baltic Cyrillic Alphabet Translator Online?

This is a character-level converter for the Baltic Cyrillic alphabet (BCA), a custom Cyrillic-style script used to write Latin-script Baltic text. You give it Latin letters and it returns the matching BCA Cyrillic characters; give it BCA Cyrillic and it returns the Latin letters. It is a substitution cipher over a fixed alphabet, not a language translator: it does not know Latvian or Lithuanian grammar, and it does not produce English meanings.

The converter works on a paired 33-letter map covering uppercase and lowercase forms, including the extended Latin letters Ģ, Ž, Ļ, Ņ, Ñ, Ķ, Č, Š, and Ė, each of which has its own distinct Cyrillic counterpart. Spaces, punctuation, digits, and line breaks pass through unchanged.

Key Features

Two-way conversion. Latin to Baltic Cyrillic and Baltic Cyrillic back to Latin, using the same map in inverted form.
Full case coverage. Every letter has an uppercase and lowercase entry, so mixed-case sentences convert consistently.
Extended-letter support. Letters such as Ģ, Ļ, Ņ, Ñ, Ķ, Č, Š, Ž, and Ė are mapped individually rather than folded to their base letters.
Visible mapping table. On request the agent prints the exact letter pairs it applied, so you can check any character.
Unsupported-character reporting. Anything outside the map is kept in place and listed, never silently deleted.
Round-trip check. For reversible text the agent can convert forward and back to confirm the result matches the original.

How to Use

Type or paste your text and say which direction you want, for example "Latin to Baltic Cyrillic: Labdien, pasaule!" If you do not state a direction, the agent infers it from the script of your text and tells you which way it went.
Read the converted text in the copyable block. The original spacing, punctuation, and line breaks are preserved.
Ask for the mapping table, a reverse conversion, or a round-trip check if you want to verify the result.

Example Use Cases

Rendering a Latvian phrase in Baltic Cyrillic script. Convert "Labdien, pasaule!" to see each letter swapped for its BCA counterpart, useful for conlang notes or decorative text.
Reading Baltic Cyrillic text back into Latin letters. Paste a line of BCA Cyrillic and get the Latin letters so you can pronounce or edit it.
Checking a mixed-case name or place name. Convert something like "Ķīpsala" or "Liepāja" and confirm the extended letters Ķ and Ģ-style characters map correctly rather than collapsing.
Verifying reversibility. Convert a sentence forward, then back, and confirm you recover the original text exactly.

Tips for Best Results

State the direction explicitly when your text is short or ambiguous, such as a single letter or a string of digits.
Keep the original text intact when you ask for a round-trip check; the agent compares against what you supplied.
If a character comes back unchanged, ask for the unsupported-character list to see whether it is outside the 33-letter map.

FAQ

What input format does it accept?
Plain text of any length, including multiple lines. Latin input may include the extended letters Ģ, Ž, Ļ, Ņ, Ñ, Ķ, Č, Š, and Ė. Digits, punctuation, and spaces are preserved as typed.

Is this a translation into English or Baltic languages?
No. It is a letter-for-letter script conversion. It does not translate meaning, and it does not add vocabulary or grammar.

How accurate is the result?
Accuracy is exact for characters inside the 33-letter map, because each substitution is deterministic. Characters outside the map are preserved and reported rather than guessed.

How is this different from some free text tools?
Some free text tools present two input boxes with no indication of direction, no visible mapping, and no report of characters they could not convert. This agent states the direction, can print the mapping table, preserves unsupported characters, and can verify a round trip. It does not claim any official or historical standard beyond the supplied map.

Can it produce audio, fonts, or handwriting?
No. The output is plain Unicode text only.
