Thaluna: Real-Time Translator

Hi! Thanks again

I want to help you solve this as quickly as possible, so I just need a few small details:

1️⃣ Windows Display Scaling

What scaling are you using in Windows?

• 100%

• 125%

• something else?

(High scaling can sometimes affect OCR.)

2️⃣ Does Snapshot Mode work normally?

When you select text manually with Snapshot Mode,
is the translation correct?

This helps me see whether the problem is Real-Time OCR or the game itself.

3️⃣ Small test

Could you try putting the Real-Time window over a simple Japanese webpage (like Wikipedia JP)?
👉 Does it translate correctly there?

If yes, then the issue is specific to the way the game renders text.

That’s all I need for now — thank you again for your patience! 😊

Hey!

Thanks again for the report — I tested the same Japanese sentence on my side and I was able to reproduce the issue.

It looks like the OCR + translation pipeline didn’t fully refresh after switching languages, which can cause unstable output or repeated text.

Here’s an easy temporary fix:

Switch the translation model to any other one (for example EN→PL or EN→EN).

Switch the OCR mode to a different one just for a moment.

Then switch everything back to your preferred setup:

Translation: Japanese → English

OCR: Japanese

This forces a full internal reset, and after doing this the translation should work correctly again.

I tested the same line using the standard Japanese OCR mode and it worked fine after resetting it this way.

If you want higher-accuracy translations, models from Ollama (like gemma3:4b) generally give better JA→EN results than the default built-in model.

For this game, please switch from Pixel Text OCR to the Standard Japanese OCR mode — that’s the one I tested and confirmed working correctly.

I’ll patch this behavior in the next update so the workaround won’t be necessary anymore.

Thanks again for helping improve the app!

Here’s the result I got on my side after the reset on ollama

Hi again!

I’ve just released a hotfix update that improves OCR/translation synchronization and fixes several UI issues.

Please download the latest version to make sure everything works correctly on your side.

A small clarification regarding the Pixel / Artistic Text OCR mode:

Even though Thaluna supports this mode, please be aware that artistic or hand-drawn fonts used in some games can produce inconsistent results.

This is normal behavior for ALL OCR engines — when fonts are stylized, the model can interpret shapes differently on each pass.

So even if the line is read correctly once,

the same screenshot may produce a slightly different result next time.

It depends on how the artistic shapes are interpreted.

I tested your screenshot here and it works correctly, but different games and unique font styles can still cause unpredictable OCR outputs in Pixel mode.

If you ever get weird results, switching briefly to:

Standard OCR,

then back to Pixel,

or changing OCR language temporarily

usually forces a clean reset and fixes the issue.

Let me know if the new hotfix solves your problem!

Oi! 
Obrigado por entrar em contato e avisar sobre o problema. 💜
Analisei o erro e ele não é causado pelo Thaluna, mas sim por uma biblioteca ausente no seu Windows.

Para corrigir, basta instalar um pacote oficial da Microsoft chamado Visual C++ Redistributable — é o mesmo usado por muitos jogos e programas.

 Siga estes passos:
1️⃣ Acesse a página oficial da Microsoft:
👉 https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist

2️⃣ Na página, procure a seção chamada “Visual Studio 2015, 2017, 2019 e 2022” e clique no link X64 (para Windows 64-bit) para baixar o instalador.
3️⃣ Execute o instalador e, quando terminar, reinicie o computador.

Depois disso, o Thaluna deve abrir normalmente.
Se ainda tiver problemas, me avise aqui — terei prazer em te ajudar!

¡Hola! 😊 Gracias por probar Thaluna.

El traductor debería funcionar sin configuración inicial, pero hay algunos pasos importantes:

1️⃣ Selecciona el modelo de traducción correcto (por ejemplo “Japanese → English”).
2️⃣ Elige el idioma OCR del texto en pantalla (por ejemplo “Japanese”).
3️⃣ Asegúrate de que la traducción no esté en pausa (si ves ▶️, haz clic para iniciar).

Ten en cuenta que el primer inicio puede tardar un poco más de lo normal, ya que Thaluna necesita inicializar algunos procesos en segundo plano antes de empezar a traducir.

Si después de un rato aún no traduce, intenta reiniciar la aplicación o mover ligeramente el marco de captura.
También puede que el equipo sea demasiado lento para el modelo seleccionado, aunque esto es poco común.

Si el problema continúa, por favor envíame una captura de pantalla y te ayudaré a resolverlo.

Hey! 😊 Thanks for reporting this.

That error happens when Thaluna tries to use GPU acceleration (PaddleOCR-GPU) but CUDA/cuDNN isn’t available on your system.

This is already fixed — the next patch will automatically switch to CPU mode instead of closing the app.

For now, you can fix it manually:
1️⃣ Go to the folder where Thaluna is installed.
2️⃣ Open the subfolder _internal.
3️⃣ Find the file config.json.
4️⃣ Open it with Notepad.
5️⃣ Find the line "ocr_device": "cuda" and change it to "cpu".
6️⃣ Save and restart Thaluna.

After that, it’ll work normally 

The issue you reported has been fixed in version 2.2 — Thaluna now automatically switches to CPU if GPU initialization fails.
You can simply re-download the latest version and it should run fine👍

Thank you so much for the kind words!  Thaluna currently works on Windows, but I’ll see what I can do about a Linux version down the line.
