Can I code DeepL?

Sending text to an existing translation API and returning the result is a thin, honest wrapper — you're integrating an existing translation model, not building one.

VIBE SCORE 99/100

how this is worked out

Why CanICodeThis says Build it

  • Submitting text to an existing translation API and displaying the result is a bounded, well-documented integration
  • A simple two-panel UI (source language, target language) is standard form work
  • Detecting the source language automatically is a feature most translation APIs already provide

Read before building

  • The underlying translation model's quality and nuance across languages is genuinely hard, specialist ML research — you're integrating an existing one
  • API costs scale with usage and character volume, so real traffic needs a pricing plan
  • Document-format translation (preserving formatting in a Word doc or PDF) is real, separate work beyond plain text

The build spec

Build me a translation tool: a two-panel UI where text typed on one side sends a request to an existing translation API and shows the result on the other, with automatic source-language detection. Use an established third-party translation API — don't attempt to build your own translation model.

What it actually costs to build

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.

AI agent — with a subscription (Claude Pro/Max, Cursor, etc.)$0 marginal
AI agent — pay-per-use API, no subscription$16–$27 one-time
Hosting, once it's running$0/mo (free tier)
Domain name, if you want your own~$12/yr

DeepL costs $8.74/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 4 months.
