Sole Engine
Every plugin that wants to be clever ends up building the same plumbing: somewhere to keep an API key, a way to count requests, a plan for when the model is slow or the network drops. Sole Engine builds it once, underneath, so the plugins on your site don't have to.
It is a shared layer of intelligence for WordPress. You install one plugin and set it up a single time. From then on, every other Sole-aware plugin on the site can reach for language-model tasks and semantic search through the same quiet backbone — one well they all draw from, instead of each one digging its own.
What that backbone offers, through a small and plain PHP interface:
- Language-model calls — chat, translation, summarization, and other prompted work, asked for in a line or two of code.
- Semantic search and similarity — embeddings and vector queries that run over the site's own content, so a plugin can find what a page means and not merely what it spells.
- A content index that keeps itself current — built and maintained in one place, so no plugin has to crawl the site and rebuild the same picture over again.
It is built for WordPress on purpose. That is where the real webmasters are — the people who tend a site day after day — and a shared engine is only worth building where plugins actually live together.
Status
In build, and honest about it. The heart of it already runs: the engine loop turns those requests into answers, and the shared plugin library is there for the plugins that will lean on it. The account dashboard, where you will set the engine up and keep an eye on it, is what we are building next. It is not yet open for signups — when it is ready to let people in, you will hear about it here.
