Plugin Description

SlyTranslate brings practical AI translation to WordPress. It is built for teams that need translation directly in editing workflows and also want the same workflows available through REST and MCP automation.

Why this plugin?

Use SlyTranslate when you need one consistent translation workflow for:

page/post translation in wp-admin
inline selected-text translation in Gutenberg
Gutenberg block translation
bulk translation from list-table actions
SEO title/description translation in the same process

Internal flow (short):

Uses native WordPress AI connectors through wp_ai_client_prompt().
Registers translation workflows as WordPress Abilities.
Exposes abilities over REST (/wp-abilities/v1/) and MCP discovery.
Supports long/structured content with chunking and output validation.
Optional direct_api_url supports OpenAI-compatible endpoints for model-specific payload needs.
In WP Multilang mode, translation state is detected from language-specific content so placeholder titles do not count as completed translations.
List-table translation now includes an explicit overwrite option with a confirmation step.
