# Glossaries

A glossary maps a source term to the translation you want AI Glot to prefer. Use it for brand vocabulary, product terms and wording that must remain consistent.

_Glossaries are organised by language pair_

## How glossaries work

Each glossary belongs to one workspace and one language pair, such as English to French. At translation planning time, AI Glot automatically takes a snapshot of the matching glossary; edits made after a batch starts affect future batches, not work already running.

```text
checkout,commande
shopping cart,panier
AI Glot,AI Glot
```

The source term is matched exactly as terminology guidance, while the translation engine still adapts grammar and surrounding sentences.

## Create or edit one

1. Open **Glossaries** in the app.
2. Choose the source and target languages.
3. Add source and preferred target terms.
4. Save. Fully empty rows are ignored; a half-filled row is rejected.

_Edit terms directly in the two-column glossary editor_

You can also manage glossaries through the [REST API](/docs/api/glossaries/list), [CLI](/docs/cli/commands#glossaries), or [MCP tools](/docs/mcp/tools#glossary-tools).

## Limits

| Plan     | Glossaries | Terms in each |
| -------- | ---------: | ------------: |
| Free     |          1 |            50 |
| Starter  |          3 |            50 |
| Pro      |  Unlimited |           150 |
| Business |  Unlimited |           500 |
| Custom   |  Unlimited |    Contracted |

Glossary size is capped because every term is added to every matching translation request. Large glossaries increase processing cost repeatedly, not only when they are saved.

> **Warning: PUT replaces everything**
>
> In the API, CLI and MCP Code Mode, a full glossary replacement deletes terms that are absent from the new set. Use the surgical update operation when you only need to add, change or remove a few terms.
