LEXA: AI Page Translator by Syntagma

LEXA — Smart AI Translator for Web Pages, Webtoons, and Manga (Bring Your Own Key)

Translate articles, documentation, comics, and images without dry machine literalism, subscription extortion, or overpaying.

🔥 The essentials of LEXA in 10 seconds

LEXA is a free extension from the Syntagma team that turns your browser into a flexible platform for smart, literary translation.

We are not selling you "just another $20/month subscription." LEXA works on the BYOK (Bring Your Own Key) principle: you connect your own API key from Gemini, OpenAI, Claude, DeepSeek, or even a free local Ollama — and you only pay the provider directly for the tokens you consume. Or you pay nothing at all.

• No accounts or registrations: You don't need to create a profile to use LEXA.
• No hidden fees: The extension doesn't charge for "proxy servers" or markup token prices.
• Absolute privacy: Your key is stored locally in your browser and never sent to our servers.
• Honest literary translation: Keeps the original layout intact, supports custom name glossaries, and allows fine-tuning of the AI's voice.

💡 Why regular translators annoy you (and how LEXA fixes this)

Most browser translators fall into one of two extremes:
1. Google Translate and Chrome Translate: Free but produce stiff, word-for-word translations that break context.
2. Commercial AI Translators: Translate well, but extort $15–30 monthly while routing requests through cheap models under the hood.

With LEXA, you get absolute control over your keys, models, and prompts.
