Translation

Linnet can translate session transcripts via the DeepL API. Translation is available on all tiers; the difference is where the API key comes from.

How to translate a session

Open a session from Session History or after ending a live session
Click Translate
Select the target language
Linnet sends the transcript text (not audio) to DeepL and returns a translated version

The translated transcript is saved alongside the original. Tone labels are preserved and displayed against the translated text.

Tier differences

Tier	DeepL key source
Free (BYOK)	Your own DeepL API key (set `DEEPL_API_KEY` in `.env`)
Paid	CF-managed key, no setup needed

BYOK = bring your own key. DeepL's free tier covers 500,000 characters per month — enough for most personal use.

Getting a free DeepL API key

Go to deepl.com and sign up for a free account
Navigate to Account then DeepL API and copy your Authentication Key

Open your Linnet .env file and add:

DEEPL_API_KEY=your-authentication-key-here

Restart Linnet

Supported languages

Translation supports all languages in DeepL's catalog. The target language list in Linnet's UI reflects DeepL's current supported outputs. See DeepL's supported languages for the full list.

Privacy note

Translation sends transcript text to DeepL's servers. Audio is never transmitted. If your session contains sensitive content, review DeepL's data privacy policy before using translation.

For fully private operation, skip translation or run a local translation model — self-hosted translation support is on the roadmap.
