Exponential Intelligence (expai) for applications #

This page is for application creators who want AI assistance in their application or want to know how it fits. Exponential Intelligence is the expai extension: a writing assistant in the administration that looks up what it needs and writes drafts as the signed-in editor, never publishing on its own (expai). Its full documentation is in its repository and in extension/expai/doc/.

What it does #

• The Intelligence tab of a node: a conversation per user and node; each lookup and draft is a step.
• The edit form: fill fields from a brief, field actions (write, rewrite, shorten, translate, suggest), presets per class, an Improve menu, alternative texts for images from a vision model.
• Vector: threads with plan and write modes, staged review, checkpoints, revert.
• Chains and translation sync run through the job queue.

Requirements and switching it on #

From the feature page: Exponential 6.0.14 or later, PHP 8.0+ with curl, dom, json, mbstring; ezjscore and ezformtoken; expqueue for queued work; a provider key or a local model (Anthropic, OpenAI-compatible services, or Ollama).

1. Activate it in each admin siteaccess (ActiveAccessExtensions[]=expai) or everywhere.
2. Put keys only in settings/override/expai.ini.append.php (mode 0640, never committed).
3. Activate and run expqueue for queued work (Queues with expqueue).

Data policy, usage and audit #

• A master switch ([AISettings] Enabled) and a veto hook.
• Per provider: a region (us, eu, local) and retention; rules per section and class.
• Every request in a usage log (user IDs only), estimated cost, limits and budgets.
• Every request, draft and draft state change in the audit trail channel ai; prompts, answers and keys are never recorded. EI: Summary gives a data protection officer one printable page.

How applications plug in #

Design rules for AI features #

• AI writes drafts; humans publish. Keep it that way in your own features.
• Run as the user, with the user's permissions.
• Keep secrets in settings, never in prompts or payloads.
• Make cost visible and limited.
