Nenex: A Neural Personal Wiki Idea
Proposal for a personal wiki built on neural nets: all edits are logged & used to finetune a NN assistant in realtime.
Main Page — ibis.wiki
Ibis is a federated encyclopedia which uses the ActivityPub protocol, just like Mastodon or Lemmy. Users can create, browse, edit articles and use many other features. If you want to start a wiki for a TV series, a videogame, or an open source project then Ibis is for you! You can register on an existing instance or install it on your own server. Then you can start editing on the topic of your choice, and connect to other Ibis instances for different topics. Federation ensures that articles get mirrored across many servers, and can be read even if the original instance goes down. Ibis is fully open source to make future enshittification impossible.
Wikidata
the free knowledge base with 120,900,955 data entities that anyone can edit.

Wiki Builder: A Claude Code Plugin for Building LLM Knowledge Bases
Wiki Builder is an open-source Claude Code plugin that turns the LLM-knowledge-base workflow into a one-command setup. Scaffold a configurable wiki, point Claude at sources, and let the agent compile durable pages, indexes, and concept maps for you.

lichen.wikiDiscovered an open source alternative to DeepWiki recently, made by @sashimikun-void.bsky.social & friends. I believe that app archetype is an outstanding use case for ‘version-control everything, so your AI-agent can’t break anything or make a mess’.
