Hi HN! I built Audarma, an open-source React library that adds LLM-powered translation to any app with just a few lines of code.

  Live demo: https://audarma.pages.dev (bonus: Latin, Klingon, Quenya, and Dothraki)

  Key features:
  • Smart caching - translates once, stores in localStorage/DB, instant on revisit
  • View-level batching - translates entire pages in one API call
  • Content-aware - only re-translates when English source changes
  • Adapter pattern - works with any LLM (OpenAI, Anthropic, Cerebras) and any database

  The demo uses Cerebras (free tier) to translate live Hacker News headlines into 10 languages including fantasy languages.

  Tech stack: React hooks, Next.js App Router, Cloudflare Pages + KV

  This is v0.1.0 (alpha) - would love feedback on the API design and use cases you'd want to support.
