Seeking feedback: dynamic_i18n — automatic dynamic translation of HTML via OpenAI

[Bona2000]

Hello everyone,

I'm relatively new to Python, and I’m currently building a chat platform. One problem I've encountered: I need to translate all HTML pages into many languages—ideally, I’d like to maintain a single source HTML in my language, and have it automatically displayed in the user’s language. The translation must be high-quality and preserve page layout (so the page doesn’t "shift" due to differences in text length).

I haven’t found any existing library that does this seamlessly at runtime with caching and layout awareness. Does anyone know of such a solution? Or would it make more sense to develop my own library—tentatively named **dynamic_i18n**—that handles dynamic translation using OpenAI, with caching, change detection, and layout stability?

Any pointers to related projects, libraries, or feedback would be greatly appreciated!

Thank you!

Hello everyone,

Since I didn’t find any ready-made solutions here, I decided to build one myself.

auto-i18n-lib — a dynamic HTML internationalization library that provides:

Automatic translation of pages into the user’s language with high quality;

Layout stability (preserving structure and design even with different text lengths);

Caching of translation results for fast rendering;

Change detection so only updated content is re-translated.

I’ve already tested the library in a real project — it works as expected.

Resources:

GitHub repository: https://github.com/Aalam2000/autoi18n/

Install via PyPI: pip install auto-i18n-lib

Feedback, ideas, and pull requests are very welcome!

you can use google cloud translate
there is an example of it's usage here
and here

[Bona2000]

That’s not it at all. It’s harder to use, and the result isn’t right.
What I ended up with is a single library that I use during rendering. I don’t touch the pages at all—they’re in one version, in a language I understand, with no modifications.

Consider using gettext or Flask-Babel for static i18n, but for dynamic translation with layout stability, your idea for dynamic_i18n sounds promising. Combine OpenAI for translation, Redis for caching, and use layout-aware diffing.

I didn’t quite understand what was removed. As I mentioned earlier, the library is already built and working. For now, it satisfies my needs, so I’m not planning to improve it further. If anyone has suggestions, I can update it.

Nice :-)

You could add openai as dependency. This would prevent the import error, if only your package is installed and openai were not.

[Bona2000]

Yes, added openai to dependencies. Thanks for the hint.
