elltwo is a python/javascript application that can be run locally or over the internet. It is ideal for small scale wiki's with lots of technical/mathematical content, writing collaborative textbooks or lecture notes, and fast (but lightweight) TeX-like formatting. Articles can be accessed/shared via URLs or exported as .tex or .md files.
Projects can be fully ungated (wiki-like decentralized editing), require a login to edit (for public viewing; e.g., lecture notes) or require a login to view (completely private mode).
elltwo features intelligent referencing, tex macros, syntax highlighting, command completion, image and figure handling, bibliographic web search/import, integrated version control, full text indexing and search, and more.
elltwo was a lockdown project of Doug Hanley and Evan Piermont. It is named after Ellsworth Avenue in Pittsburgh.
