Compatibility
What it works with
Requirements and supported providers, models and plugins for version 1.6.0 of the free plugin and for AI Blog Writer Pro.
WordPress and PHP
| WordPress | 6.0 or later, tested up to 7.1 |
|---|---|
| PHP | 7.4 or later |
| Editor | Drafts are core blocks. The sidebar with provenance, sources, section rewrites and SEO suggestions needs the block editor. |
| Multisite | Yes. Activate per site or network-wide; each site keeps its own keys, settings, jobs and writer profiles. |
| Themes | Any theme that displays core blocks. |
Server
| Outbound HTTPS | To your AI provider's API, and to the source URLs you supply. |
|---|---|
| Sodium | To save API keys encrypted in the database (included in PHP since 7.2). Without it, define the key in wp-config.php instead. |
| Background jobs | WP-Cron, or a server scheduler calling wp-cron.php every minute if DISABLE_WP_CRON is set. See Background jobs and WP-Cron. |
| WP-CLI | Optional: wp aibcg job run <job-id> runs one stage of a job. |
