# Tier System

Linnet is available on two tiers. All core functionality runs locally on the Free tier.

## Comparison

| Feature | Free | Paid |
|---------|:----:|:----:|
| Real-time transcription (local Whisper) | Yes | Yes |
| Tone annotation (local SER) | Yes | Yes |
| Elcor mode | Yes | Yes |
| Speaker diarization | Yes | Yes |
| Session history | 30 days | Unlimited |
| Corrections + local model retraining | Yes | Yes |
| Meeting notes export (Markdown, plain text, CSV) | Yes | Yes |
| Embeddable widget | Yes | Yes |
| Translation (BYOK: your own DeepL key) | Yes | Yes |
| Translation (CF-managed DeepL key) | No | Yes |

SER = speech emotion recognition. BYOK = bring your own key.

## Free tier

The Free tier is fully functional for personal, non-commercial use. Transcription, tone annotation, Elcor mode, speaker diarization, corrections, and export all work without a license key or an internet connection.

The only limitations are:
- Session history is retained for 30 days
- Translation requires your own DeepL API key (DeepL offers a free tier at 500,000 characters/month)

## Paid tier

The Paid tier adds:
- Unlimited session history retention
- CF-managed DeepL key (translation works without your own key)

## License keys

License keys use the format `CFG-LNNT-XXXX-XXXX-XXXX`. Enter your key in **Settings** then **License**.

Free keys for personal use are available at [circuitforge.tech/software](https://circuitforge.tech/software).
