We built NeoWiki for use cases including:
- Policy and process documentation
- Project databases and expertise directories
- Authority files and controlled vocabularies
- Museum collections you can publish as linked open data
The official MediaWiki Docker images ship 8.3.36 now: pull and recreate to be safe. Can't update yet? Take the wiki offline until you can.
If your wiki is hosted with us, it is already patched.
🚨 Running MediaWiki? Update PHP now!
PHP has two critical remote code execution vulnerabilities, patched earlier today. watchTowr reports exploitation in the wild.

Same question, different user, different answer, by design!
An admin asks about executive pay and gets a cited answer. A regular employee gets none: the AI Assistant only draws on pages the asking user may read.

Choose the AI behind your wiki's answers!
Configure your MediaWiki chatbot via the admin panel: Anthropic, OpenAI, Google, Mistral, Apertus, or your own self-hosted model. Tune the chat features and apply your branding.

Ask your wiki in any language!
The AI Assistant replies in your language, even when the wiki content is in another. A German question on an English wiki gets a German answer, with citations.

We've released Chameleon 6!
The highly flexible MediaWiki skin now builds on Bootstrap 5: all Bootstrap 5 classes and utilities work in your wikitext and templates, and many customizations are plain CSS edits instead of SCSS recompiles.
