Fetchub

Fetchub is an advanced WordPress plugin that automates the aggregation, translation, and publication of RSS feeds. It fetches feed items, detects their language, and translates them into a target language using AI providers such as OpenAI, Gemini, Claude, and Grok. With features like AI-driven content ranking, customizable cron intervals per feed, and an intuitive admin interface, Fetchub streamlines content management. The plugin requires a valid token for full functionality, offering new users a 3-day trial to explore its capabilities.

• Manual Fetching: Trigger instant feed updates via AJAX with buttons for individual or all feeds.
• Feed Configuration: Define intervals, categories, maximum posts, AI models, temperature, custom prompts, target languages, and block words per feed.

• PHP 7.4 or higher
  – required for arrow functions (fn()) and modern language features.
  – fully tested on PHP 8.0, 8.1, 8.2, 8.3 and 8.4.
• Standard PHP extensions: cURL, OpenSSL, and DOM/XML (all enabled by default on mainstream hosts).
• WP-Cron active (or a real system cron) so per-feed schedules can run.
• 512 MB memory_limit or greater recommended when using multiple AI models.

Best practice for performance
For the smoothest AI processing and zero-maintenance cron execution, we recommend hosting your WordPress site on ihost WordPress Cloud Hosting.
